i'm using "openapi-generator-maven-plugin" version 6.2.1 for generate modules from a YAML file and consume a RestAPI.
The code that is generated from the plugin looks fine and it work great with "GET" requests, the problem that i've encountered so far, is on "POST" requests. Apparently when I pass an object with null values (even if they are nullable) it throws "Unable to serialize property" from [org.eclipse.yasson.internal.Marshaller], even if the object is Serializable.
More specific:
I've this object generated from the plugin.

When I make the request the only property that I set for the moment is the "link" property, because the REST service knows what to do.
public File getFileByLink(String link) throws WebServiceException, DataNotFoundException {

File file;
try {
ModelFile inputFile = new ModelFile();
inputFile.setLink(link);

}
Now when it perform the actual request and try to serialize the object throws this error:
13:55:36,124 SEVERE [org.eclipse.yasson.internal.Marshaller] (default task-1) Unable to serialize property 'data_JsonNullable' from org.openapitools.client.model.ModelFile

At first I didn't use the property <serializableModel>true</serializableModel>, and I thought that the object could not be searialized for this problem, but even if the class implement the Serializable interface the problem still occur.
If can help, I've tried to set values to all the object's properties and as long as they are not null, there's non serialization problems. The problem occur when there's at least one property that is null.

Please let me know if I need to provide further information. i am trying to get better at how i post questions here. I searched for a long time before asking but all I can find is that it might be something with my equals/hash code. I'm just not sure what is getting changed when the comparison is made because it is not happening with my other objects.
Thank you for any hints, and please don't bite my head off!
It seems some fields are not equal. try to compare all fields one by one to identify non-equal fields: assertEquals(fromDao.getOrgId(), org.getOrgId() and all the rest of organization's fields)
Thank you all for your assistance! I was able to convert my org and fromDao objects to string to see them in the test window. The problem was with my Mapper method for the Organization object. See original and the fix below:
Original Version
private static final class OrgMapper implements RowMapper<Organization> {
#Override
public Organization mapRow(ResultSet rs, int i) throws SQLException {
Organization org = new Organization();
org.setOrgId(rs.getInt("org_id"));
org.setOrgName(rs.getString("org_name"));
org.setOrgDescription(rs.getString("org_description"));
org.setOrgPhone(rs.getString("org_phone"));
org.setOrgEmail(rs.getString("org_street_address")); //wrong field
org.setOrgCity(rs.getString("org_city"));
org.setOrgState(rs.getString("org_state"));
org.setOrgZipCode(rs.getString("org_zip_code"));
return org;
}
}
Fixed OrgMapper:
private static final class OrgMapper implements RowMapper<Organization> {
#Override
public Organization mapRow(ResultSet rs, int i) throws SQLException {
Organization org = new Organization();
org.setOrgId(rs.getInt("org_id"));
org.setOrgName(rs.getString("org_name"));
org.setOrgDescription(rs.getString("org_description"));
org.setOrgPhone(rs.getString("org_phone"));
org.setOrgEmail(rs.getString("org_email"));
org.setOrgStreetAddress(rs.getString("org_street_address"));
org.setOrgCity(rs.getString("org_city"));
org.setOrgState(rs.getString("org_state"));
org.setOrgZipCode(rs.getString("org_zip_code"));
return org;
}
I have a GraphQL query similar to this:
query {
getPosts {
...PostFragment
}
}
fragment SpecificPostFragment on SpecificPost {
owner {
id
name
}
}
fragment PostFragment on Post {
id
object
... on SpecificPost {
...SpecificPostFragment
}
}
I try to know if:
the field object is requested
the field owner is requested
I try to apply what is written here:
https://www.graphql-java.com/documentation/v11/fieldselection/
But dataFetchingEnvironment.getSelectionSet().contains("XXX") does not seem to work well with fragments.
How to do that ?
I haven't found any built-in solution, so I wrote my own. Here is my code
import java.util.List;
import java.util.Objects;
import java.util.stream.Collectors;
import java.util.stream.Stream;
import graphql.execution.MergedField;
import graphql.language.Field;
import graphql.language.FragmentDefinition;
import graphql.language.FragmentSpread;
import graphql.language.InlineFragment;
import graphql.language.SelectionSet;
import graphql.schema.DataFetchingEnvironment;
public class GraphQLUtil {
private static class PathElement {
private final String name;
private final String typeName;
public PathElement(String name, String typeName) {
this.name = name;
this.typeName = typeName;
}
public String getName() {
return name;
}
public String getTypeName() {
return typeName;
}
}
public static boolean containsIncludingFragments(DataFetchingEnvironment env, String path) {
Objects.requireNonNull(env, "The data fetching environment must not be null");
Objects.requireNonNull(path, "The field path must not be null");
List<PathElement> elts = Stream.of(path.split("/")).map(p -> {
String pt = p.trim();
if (pt.isEmpty()) {
throw new IllegalArgumentException("Empty path element found");
}
int sepIdx = pt.indexOf(":");
String name = pt;
String typeName = null;
if (sepIdx >= 0) {
typeName = pt.substring(0, sepIdx);
name = pt.substring(sepIdx + 1, pt.length());
}
return new PathElement(name, typeName);
}).collect(Collectors.toList());
if (elts.isEmpty()) {
return false;
}
MergedField mf = env.getMergedField();
return searchPathElement(env, elts, 0, mf.getSingleField().getSelectionSet(), null);
}
private static boolean searchPathElement(
DataFetchingEnvironment env,
List<PathElement> elts,
int eltIndex,
SelectionSet selectionSet,
String selectionTypeName) {
if (eltIndex >= elts.size()) {
return true;
}
PathElement currentElt = elts.get(eltIndex);
String currentName = currentElt.getName();
String currentTypeName = currentElt.getTypeName();
List<Field> fields = selectionSet.getSelectionsOfType(Field.class);
boolean found = false;
for (Field f : fields) {
if (f.getName().equals(currentName) && (currentTypeName == null
|| selectionTypeName == null
|| currentTypeName.equals(selectionTypeName))) {
found = searchPathElement(env, elts, eltIndex + 1, f.getSelectionSet(), null);
if (found) {
return true;
}
}
}
List<FragmentSpread> fragments = selectionSet.getSelectionsOfType(FragmentSpread.class);
for (FragmentSpread f : fragments) {
FragmentDefinition fDef = env.getFragmentsByName().get(f.getName());
found = searchPathElement(env, elts, eltIndex, fDef.getSelectionSet(), fDef.getTypeCondition().getName());
if (found) {
return true;
}
}
List<InlineFragment> inlineFragments = selectionSet.getSelectionsOfType(InlineFragment.class);
for (InlineFragment f : inlineFragments) {
found = searchPathElement(env, elts, eltIndex, f.getSelectionSet(), f.getTypeCondition().getName());
if (found) {
return true;
}
}
return false;
}
}
And you call it like this:
DataFetchingEnvironment dataEnv = ... // If like me you use GraphQL SPQR, you can get it with io.leangen.graphql.execution.ResolutionEnvironment
boolean t1= GraphQLUtil.containsIncludingFragments(dataEnv, "id");
boolean t2 = GraphQLUtil.containsIncludingFragments(dataEnv, "owner/id");
boolean t3 = GraphQLUtil.containsIncludingFragments(dataEnv, "SpecificPost:owner/id"); // You may give the type of the field, if in some inheritance scenario, it is ambiguous
Note that this solution does not support wild card (* or ?). And I haven't tested it if the main query contains multiple entries (getPost + getPeople in the same query for example), but that probably does not work in that case.
So, this isn't how to find method references using Eclipse IDE.
I need to find them via code (Java).
Background:
We have hundreds of projects, all based off a common project. Over the years, the common project has some really bad code that has been replaced. The bad code has been marked as Deprecated.
Now, I want to remove all the deprecated code. But, I want to create some code to migrate all the other projects we have.
Approach:
Now, for some things, I could search the project code for some keywords (i.e method name) and replace with something else. However, there are some method names that would collide and doing a simple search/replace would not work.
My thought is, if I have a deprecated method:
com.foo.bar.SomeClass.someMethod(String)
Then some way to find every place that someMethod(String) is used, I could then replace that one with newMethod(String)
I have looked some at:
org.reflections.Reflections
ASM
Basically, I want to create a migration program to make migrating to the new common code simple. I plan to use this same migration code to help migrate the projects from JDK8 to OpenJDK11.
Thoughts on how I can accomplish this?
You can certainly use ASM with a ClassVisitor / MethodVisitor to find all references to this method.
You just have to override visitMethod in the ClassVisitor to return your own MethodVisitor, and in the MethodVisitor override visitMethodInsn.
In the visitMethodInsn you check if the target is one of the deprecated methods, and log where it is used. Here an example:
import java.io.File;
import java.io.IOException;
import java.io.UncheckedIOException;
import java.util.jar.JarEntry;
import java.util.jar.JarFile;
import org.objectweb.asm.ClassReader;
import org.objectweb.asm.ClassVisitor;
import org.objectweb.asm.MethodVisitor;
import static org.objectweb.asm.Opcodes.*;
public class MethodScanner extends ClassVisitor {
private final String fileName;
private MethodScanner(String fileName) {
super(ASM7);
this.fileName = fileName;
}
public static void main(String[] args) throws IOException {
scanJar(new File("path/to/some.jar"));
}
public static void scanJar(File jarFile) throws IOException {
var jf = new JarFile(jarFile);
jf.stream().filter(je -> getFileExtension(je.getName()).equals(".class"))
.forEach(je -> processEntry(jf, je));
}
private static String getFileExtension(String name) {
int idx = name.lastIndexOf(".");
if (idx == -1)
return "";
return name.substring(idx);
}
private static void processEntry(JarFile jf, JarEntry je) {
try {
byte[] bytes = jf.getInputStream(je).readAllBytes();
MethodScanner ms = new MethodScanner(jf.getName() + "!" + je.getName());
ClassReader cr = new ClassReader(bytes);
cr.accept(ms, 0);
} catch (IOException ioe) {
throw new UncheckedIOException(ioe);
}
}
#Override
public MethodVisitor visitMethod(int access, String name, String descriptor, String signature,
String[] exceptions) {
return new MethodScannerVisitor(super.visitMethod(access, name, descriptor, signature, exceptions), fileName, name + descriptor);
}
private static class MethodScannerVisitor extends MethodVisitor {
private final String fileName;
private final String methodName;
private MethodScannerVisitor(MethodVisitor parent, String fileName, String methodName) {
super(ASM7, parent);
this.fileName = fileName;
this.methodName = methodName;
}
#Override
public void visitMethodInsn(int opcode, String owner, String name, String descriptor, boolean isInterface) {
super.visitMethodInsn(opcode, owner, name, descriptor, isInterface);

System.out.println("reference to Math.random() from " + fileName + " in " + methodName);
}
}
}

classUsed[com.e2open.selenium.api_common.AbstractPage]; methodUsed[radioButtonGet]; methodParameters[(Ljava/lang/String;Ljava/lang/String;)Lorg/openqa/selenium/WebElement;]
However, the results are not correct.
If I take one of the methods:
com.e2open.selenium.api_common.abstractHelpers.SystemInformation.isInternetExplorer8()
And use Eclipse to find References, I get
isInternetExplorer8 Eclipse References Image
And for the other method doing a search on:
com.e2open.selenium.api_common.AbstractPage.radioButtonSelect(String, String)
radioButtonSelect Eclipse Reference Image
I am unsure what to change or where to go from here.
I have a problem in getting checkbox's value from JSP.
I used SpringMVC, and my related class as follows:
Form:
#Getter #Setter
public class Sample3Form extends AbstractForm {<
private List<Sample1Bean> sampleList; //all data
private ValidPagedListHolder<Sample1Bean> samplePagedList;//1 page data
}
the class to control changing page:
ValidPagedListHolder:
#SuppressWarnings("serial")
public class ValidPagedListHolder<E> extends PagedListHolder<E> implements
Serializable {
...
...
/**
* Return a sub-list representing the current page.
*/
#Override
#Valid
public List<E> getPageList() {
return super.getPageList();
}
/**
* コンストラクタ生成時の初期化処理を行うメソッド
*/
protected void init() {
setPageSize(DEFAULT_PAGE_SIZE);
}
}
Sample1Bean:
#Getter #Setter
public class Sample1Bean extends AbstractOnlineDataBean {
private String keiyakuno;
private String keiyakunm;
private String torisakino;
}
Parent Bean Class:
#Getter
#Setter
public abstract class AbstractOnlineDataBean extends AbstractDataBean {
private Integer selectedIndex;
private String maskPattern;
}
Controller:
#Controller
#RequestMapping(value = "app/sample3")
#SessionAttributes(value = "sample3Form")
#NotCheckToken
public class SampleController3 extends AbstractController {
private static Logger logger = LoggerFactory.getLogger(UserUtil.class);
#ModelAttribute(value = "sample3Form")
public Sample3Form getForm() {
return new Sample3Form();
}
......
......
#RequestMapping(value = "delete")
public String delete(Model model, #Validated Sample3Form form, BindingResult result, HttpServletRequest request) throws GdcSystemException {
List<Sample1Bean> list = new ArrayList<Sample1Bean>();
int size = form.getSampleList().size();
ValidPagedListHolder<Sample1Bean> plist = form.getSamplePagedList();
list = plist.getPageList();
for (int i = 0 ; i < size; i ++) {
if (form.getSampleList().get(i).getSelectedIndex() == null ) {
} else {
//I cannot arrive here even though I checked in JSP
list.add(form.getSampleList().get(i));
}
}
...
...
}
JSP:
<ab:form id="sample3" action="submit" modelAttribute="sample3Form">
<table width="100%" class="tableborder" cellpadding="0" cellspacing="0">
...
...
<ab:tr index="${row.index}">
<td width="2%" class="data_list_area">
<ab:checkbox path="${sample3Form.samplePagedList.pageList[row.index].selectedIndex}" fwformat='NONE'
value="${sample3Form.samplePagedList.page * sample3Form.samplePagedList.pageSize + row.index }" name="checkedids"/>
</td>
<td width="5%" class="data_list_area">
<!--ab:out value="${sample3Form.samplePagedList.pageList[row.index].keiyakuno}" /-->
<ab:label path="" fwformat='NONE'>${sample3Form.samplePagedList.pageList[row.index].keiyakuno}</ab:label>
</td>
...
...
In above JSP, I set checkboxes and bind the checkboxes to selectedIndex property for for every row data.but i cannot get selected row in controller as follows:
form.getSampleList().get(i).getSelectedIndex()
The return value is always null.
why? Could who please tell me how i can get the selectedIndex in controller?
By the way, I can get checked row in controller like below:
String[] arr = request.getParameterValues("checkedids");
Remarks: in JSP, These added checkboxes is defined by name "checkedids".
and <ab:checkbox> is a tag class extends AbstractSingleCheckedElementTag.
the src for CheckboxTagImpl is here:

Thanks.
Essentially, this is the kind of data I want returned:
{
"Top10BidAsks":[
{
"Bid":{
"Price":10.0,
"Size":2.0,
"ExchangeID":"SMART",
"timeStamp":0
},
"Ask":{
"Price":12.0,
"Size":2.0,
"ExchangeID":"SMART",
"timeStamp":0
}
},
{
"Bid":{
"Price":0.0,
"Size":0.0,
"ExchangeID":"SMART",
"timeStamp":0
},
"Ask":{
"Price":13.0,
"Size":12.0,
"ExchangeID":"SMART",
"timeStamp":0
}
}
]
}
The {"Price":10.0,"Size":2.0,"ExchangeID":"SMART","timeStamp":0}, essentially represents a MarketData Object that I've created with those 4 fields.
The main function I'm calling is:
public MarketDataListLevel2 getMarketDataDepth() {
try {
MarketDataListLevel2 md = cs.getMarketDataDepth();
log.info(md.toString());
return md;
}
catch ( Exception e) {
....
}
}
Where cs is just an interface that retrieves the JSON data from a site.
The MarketDataLevel2 object is:
public class MarketDataListLevel2 {
public static class MarketDataList {
public MarketData[] a;
}
public MarketDataList[] listofmarketdatalists;
public MarketDataListLevel2(#JsonProperty("Top10BidAsks") MarketDataList[] listofmarketdatalists) {
this.listofmarketdatalists = listofmarketdatalists;
}
I tried to make this object match the output I want (formatting wise), but apparently I might have a data structure error here, because I'm not getting the data I want returned.
When I run the first method that I listed:
MarketDataListLevel2 a = getDepthMarketData(coin);
When I debug this 'a' object, I see that each element in the listofmarketdatalists array is 'null'
instead of containing an object with this format: {"Bid":{"Price":10.0,"Size":2.0,"ExchangeID":"SMART","timeStamp":0},
"Ask":{"Price":12.0,"Size":2.0,"ExchangeID":"SMART","timeStamp":0}}.
Any advice would be awesome.
You have to create correct POJO classes which represent your JSON. See below example:
import java.math.BigDecimal;
import java.util.HashMap;
import java.util.List;
import java.util.Map;
import com.fasterxml.jackson.annotation.JsonAnySetter;
import com.fasterxml.jackson.annotation.JsonProperty;
import com.fasterxml.jackson.databind.ObjectMapper;
public class JacksonProgram {
public static void main(String[] args) throws Exception {
ObjectMapper mapper = new ObjectMapper();
Root root = mapper.readValue(json, Root.class);
System.out.println(root.getTop10());
}
}
class Root {
#JsonProperty("Top10BidAsks")
private List<MarketDataEntity> top10;
public List<MarketDataEntity> getTop10() {
return top10;
}
public void setTop10(List<MarketDataEntity> top10) {
this.top10 = top10;
}
}
class MarketDataEntity {
private Map<String, MarketData> datas = new HashMap<String, MarketData>();
#JsonAnySetter
public void setMarketData(String key, MarketData data) {
datas.put(key, data);
}
#Override
public String toString() {
return datas.toString();
}
}
class MarketData {
#JsonProperty("Price")
private BigDecimal price;
#JsonProperty("Size")
private BigDecimal size;
#JsonProperty("ExchangeID")
private String exchangeId;
private int timeStamp;
public BigDecimal getPrice() {
return price;
}
public void setPrice(BigDecimal price) {
this.price = price;
}
public BigDecimal getSize() {
return size;
}
public void setSize(BigDecimal size) {
this.size = size;
}
public String getExchangeId() {
return exchangeId;
}
public void setExchangeId(String exchangeId) {
this.exchangeId = exchangeId;
}
public int getTimeStamp() {
return timeStamp;
}
public void setTimeStamp(int timeStamp) {
this.timeStamp = timeStamp;
}
#Override
public String toString() {
return "MarketData [price=" + price + ", size=" + size + ", exchangeId=" + exchangeId + ", timeStamp=" + timeStamp + "]";
}
}
Above program prints:
[{Bid=MarketData [price=10.0, size=2.0, exchangeId=SMART, timeStamp=0], Ask=MarketData [price=12.0, size=2.0, exchangeId=SMART, timeStamp=0]}, {Bid=MarketData [price=0.0, size=0.0, exchangeId=SMART, timeStamp=0], Ask=MarketData [price=13.0, size=12.0, exchangeId=SMART, timeStamp=0]}]
