using JPA to connect to database using spring and inteliJ

using JPA to connect to database using spring and inteliJ - java

I am trying to use JPa to connect to my mysql database.
I have generated persistance.xml:
<?xml version="1.0" encoding="UTF-8"?>
<persistence xmlns="http://java.sun.com/xml/ns/persistence" version="2.0">

<property name="toplink.jdbc.password"/>
</properties>
</persistence-unit>
</persistence>
and alsto by doing it intelij generated POJO class:
#Entity
#Table(name = "torko", schema = "tornoci", catalog = "")
public class TorkoEntity {
private int id;
private String meno;
TorkoEntity(){}
#Id
#Column(name = "Id", nullable = false)
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
#Basic
#Column(name = "meno", nullable = false, length = 250)
public String getMeno() {
return meno;
}
public void setMeno(String meno) {
this.meno = meno;
}
#Override
public boolean equals(Object o) {
if (this == o) return true;
if (o == null || getClass() != o.getClass()) return false;
TorkoEntity that = (TorkoEntity) o;
if (id != that.id) return false;
if (meno != null ? !meno.equals(that.meno) : that.meno != null) return false;
return true;
}
#Override
public int hashCode() {
int result = id;
result = 31 * result + (meno != null ? meno.hashCode() : 0);
return result;
}
}
I have created entity manager and want to get results from it :
public class manager {
#PersistenceContext
EntityManager em;
manager(){}
public List<TorkoEntity> getHim(){
Query q = em.createNativeQuery("SELECT * FROM TorkoEntity", TorkoEntity.class);
return q . getResultList();
}
}
and route:
#RestController
public class test {
#RequestMapping( value = "hi" , method = RequestMethod.GET)
public String testt(){
manager m = new manager();
List<TorkoEntity> t = m.getHim();
return t.get(0).getMeno();
}
}
however when i navigate to localhost:8080/hi
it throws
Whitelabel Error Page
This application has no explicit mapping for /error, so you are seeing this as a fallback.

I have no idea what can cause this problem , all help is highly appreciated

The problem seems to be, that you are creating with this part
manager m = new manager();
You should autowire your manager class into your controller to make it work. If you debug your program, you should see, that manager is null.
A good answer is here:
Why is my Spring #Autowired field null?

The problem with the field is the type of which is another class

I created a field that is converted into another class, through which I get json, where the problem occurs, but I can't understand what I'm doing wrong
User class
public class User extends BaseEntity<Integer> {
private String firstName;
private String lastName;
#Column(name = "username")
private String username;
#Convert(converter = PurshasedProductConverter.class)
private PurshasedProductConverter purshasedProducts;
}
PurshasedProductConverter class
public class PurshasedProductConverter implements AttributeConverter<PurshasedProduct, String> {
private static final Logger LOG = (Logger) LoggerFactory.getLogger(PurshasedProductConverter.class);
private final ObjectMapper mapper = new ObjectMapper();
#Override
public String convertToDatabaseColumn(PurshasedProduct attribute) {
try {
if (attribute != null)
return mapper.writeValueAsString(attribute);
else
return null;
} catch (JsonProcessingException e) {
LOG.error(e.getMessage(), e);
throw new RuntimeException(e);
}
}
#Override
public PurshasedProduct convertToEntityAttribute(String dbData) {
TypeReference<HashMap<String, String>> typeRef
= new TypeReference<HashMap<String, String>>() {
};
try {
PurshasedProduct purshasedProduct = new PurshasedProduct();
if (dbData != null)
purshasedProduct.strings = mapper.readValue(dbData, typeRef);
return purshasedProduct;
} catch (IOException e) {
LOG.error(e.getMessage(), e);
throw new RuntimeException(e);
}
}
}
PurshasedProduct class
public class PurshasedProduct {
public Map<String, String> strings = new HashMap<>();
public static PurshasedProduct create(String key, String value) {
PurshasedProduct purshasedProduct = new PurshasedProduct();
purshasedProduct.set(key, value);
return purshasedProduct;
}
public void set(String lang, String text) {
if (text == null || lang == null) {
return;
}
strings.put(lang, text);
}
public String get(String lang) {
if (lang == null) {
return null;
}
if (strings.containsKey(lang)) {
return strings.get(lang);
}
return null;
}
public void remove(String lang) {
if (lang == null) {
return;
}
if (strings.containsKey(lang)) {
strings.remove(lang);
}
}
public Set<String> getLangs() {
return strings.keySet();
}

return CollectionUtils.isEqualCollection(strings.entrySet(), that.strings.entrySet());
}
#Override
public String toString() {
return "PurshasedProduct{" +

'}';
}
}
When building the application, no error occurs, an error occurs when I try to enter the admin. Here are the logs :

Take a look:

private PurshasedProductConverter purshasedProducts;
You used PurshasedProductConverter in annotation and field type as well. You should change it to field type which are you converting from/to in PurshasedProductConverter.
#Convert(converter = PurshasedProductConverter.class)
private PurshasedProduct purshasedProducts;

Spring Cloud REST: 400 while requesting for a JWT token

I'm trying to receive a token object from an AUTH service, but I keep getting a 400 message. With POSTMAN the request with such header + body works fine.
Request code:
...
HttpHeaders httpHeaders = new HttpHeaders();
String auth = "app" + ":" + "thisissecret";
byte[] encodedAuth = Base64.encodeBase64(auth.getBytes(Charset.forName("US-ASCII")));
String authHeader = "Basic " + new String(encodedAuth);
httpHeaders.set("Authorization", authHeader);
Map <String, Object> body = new HashMap <>();
body.put("grant_type", "password");
body.put("scope", "webclient");
body.put("username", authEntity.getUsername());
body.put("password", authEntity.getPassword());
HttpEntity <Map> requestEntity = new HttpEntity <>(body, httpHeaders);
ResponseEntity <Token> loginResponse = restTemplate.exchange(AUTHORIZATION_URL, HttpMethod.POST, requestEntity, Token.class);
The last line is what generates the 400 error.
Here is the Token class:
public class Token {
private String accessToken;
private String tokenType;
private String refreshToken;
private String expiresIn;
private String scope;
private String organisationId;
private String jti;
... getters / setters
And here is how the response json object supposed to look like:
{
"access_token": "*****",
"token_type": "bearer",
"refresh_token": "*****",
"expires_in": 43199,
"scope": "webclient",
"organisationId": "*****",
"jti": "***"
}
And the exception itself:
Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception [Request processing failed; nested exception is org.springframework.web.client.HttpClientErrorException: 400 null] with root cause

Thanks in advance!!

I've solved the problem with this code. Notice the 'MultiValueMap' and 'RestTemplate'.
ClientHttpRequestFactory requestFactory = new
HttpComponentsClientHttpRequestFactory(HttpClients.createDefault());
RestTemplate restTemplate = new RestTemplate(requestFactory);
HttpHeaders httpHeaders = new HttpHeaders();
String auth = "app" + ":" + "thisissecret";
byte[] encodedAuth = Base64.encodeBase64(auth.getBytes(Charset.forName("US-ASCII")));
httpHeaders.setContentType(MediaType.APPLICATION_FORM_URLENCODED);
String authorisation = "Basic " + new String(encodedAuth);
httpHeaders.add("authorization", authorisation);
MultiValueMap <String, String> body = new LinkedMultiValueMap <>();
body.add("scope", "webclient");
body.add("grant_type", "password");
body.add("username", authEntity.getUsername());
body.add("password", authEntity.getPassword());
HttpEntity <MultiValueMap <String, String>> requestEntity = new HttpEntity <>(body, httpHeaders);
ResponseEntity <Token> loginResponse = null;
try {
loginResponse = restTemplate.exchange(AUTHORIZATION_URL, HttpMethod.POST, requestEntity, Token.class);
} catch (HttpClientErrorException ex) {
log.error("Exception: {}", ex.getLocalizedMessage());
response.setStatus(HttpServletResponse.SC_UNAUTHORIZED);
}

run a simple spring batch from restcontroller

when i run the spring boot application,the batch works perfectly without instantiating the JobLauncher,i think because of the annotation #EnableBatchProcessing,but when i enter a specific url to launch the same batch in restController by instantiating the JobLauncher and guetting the initial job from the context it fails,here is the code :
#RestController
#Import(BatchConfiguration.class)
#EnableBatchProcessing
public class BatchController {
#Autowired
JobLauncher jobLauncher;
#RequestMapping("/run")
public void runBatch() {
System.out.println("starting the job..........");
ApplicationContext context = new AnnotationConfigApplicationContext(
"src/main/resources/batchjob.xml");
Job job = (Job) context.getBean("job");
try {
JobParameters jobParameters = new JobParametersBuilder().addLong(
"time", System.currentTimeMillis()).toJobParameters();
jobLauncher.run(job, jobParameters);
} catch (JobExecutionAlreadyRunningException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (JobRestartException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (JobInstanceAlreadyCompleteException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (JobParametersInvalidException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
System.out.println("finishing the job..........");
}
}

Spring boot: Handle Custom Exceptions using ControllerAdvice for REST

I want to handle all exceptions at one place using #ControllerAdvice. I have written generic Exception handler class which is:
#ControllerAdvice(basePackageClasses = RepositoryRestExceptionHandler.class)
public class GenericRepositoryRestExceptionHandler{
#Autowired
MessageSource messageSource;
#ExceptionHandler
ResponseEntity<?> handleConflict(DataIntegrityViolationException e) {
return response(HttpStatus.CONFLICT, 40901, "Operation cannot be performed. Integrity Constraint violated", e.getRootCause().getMessage(), "");
}
#ExceptionHandler(InconsistentEditException.class)
ResponseEntity<?> handleInconsistentEditException(InconsistentEditException e){
return response(HttpStatus.CONFLICT, 40902, e.getMessage());
}
private ResponseEntity<RestError> response(HttpStatus status, int code, String msg) {
return response(status, code, msg, "", "");
}
private ResponseEntity<RestError> response(HttpStatus status, int code, String msg, String devMsg, String moreInfo) {
return new ResponseEntity<>(new RestError(status.value(), code, msg, devMsg, moreInfo), status);
}
}
This exception handler is working for exception thrown by DB operation: DataIntegrityViolationException but not for my custom exception: InconsistentEditException which is:
public class InconsistentEditException extends RuntimeException{
public InconsistentEditException(String message){
super(message);
}
public InconsistentEditException(String message, Throwable cause){
super(message, cause);
}
}
it returning this response for my custom exception:
{
"timestamp":1484673344950,
"status":500,
"error":"Internal Server Error",
"exception":"com.example.vmi.exception.InconsistentEditException",
"message":"Operation restricted to prevent data Inconsistency.",
"path":"/api/fits/2"
}
I am expecting this response:
{
"status":409,
"code":40902,
"message":"Operation restricted to prevent data Inconsistency.",
"devMessage":"",
"moreInfo":""
}
I don't know why custom exception is not handled by Exception handler. What am I missing?
Edit: Adding class where custom exception is thrown.
#Service
#Transactional(readOnly = true)
public class FitService {
private final Logger logger = LoggerFactory.getLogger(BuyerService.class);
#Autowired FitRepository fitRepository;
#Autowired SKURepository skuRepository;
public Fit findOne(Integer id) {
return fitRepository.findOne(id);
}
public Fit findOne(String name) {
return fitRepository.findByName(name);
}
#Transactional
public Fit updateFit(Fit fit){
System.out.println("No. of Skus: " + skuRepository.countByFit(fit));
if (skuRepository.countByFit(fit) > 0){
throw new InconsistentEditException("Operation restricted to prevent data Inconsistency.");
}
Fit fit2 = fitRepository.findOne(fit.getId());
fit2.setName(fit.getName());
return fit2;
}
}

You're missing one annotation:
#EnableWebMvc
#ControllerAdvice
public class GenericRepositoryRestExceptionHandler{
#Autowired
MessageSource messageSource;
#ResponseBody
#ExceptionHandler
ResponseEntity<?> handleConflict(DataIntegrityViolationException e) {
return response(HttpStatus.CONFLICT, 40901, "Operation cannot be performed. Integrity Constraint violated", e.getRootCause().getMessage(), "");
}
#ResponseBody
#ExceptionHandler(InconsistentEditException.class)
ResponseEntity<?> handleInconsistentEditException(InconsistentEditException e){
return response(HttpStatus.CONFLICT, 40902, e.getMessage());
}
private ResponseEntity<RestError> response(HttpStatus status, int code, String msg) {
return response(status, code, msg, "", "");
}
private ResponseEntity<RestError> response(HttpStatus status, int code, String msg, String devMsg, String moreInfo) {
return new ResponseEntity<>(new RestError(status.value(), code, msg, devMsg, moreInfo), status);
}
}
is what you're looking for.
Removing basePackages solved the problem.

SseEmitter and jackson No suitable converter for class java.lang.String

I'm trying to send messages from backend to frontend with SseEmitter from spring 4.2.6 but when I'm send some message or object, I'm getting the error No suitable converter for class java.lang.String because we have the jackson converter on our application, here is the code.

A little bit late but worth mentioning to try to declare a StringHttpMessageConverter bean and add it to the configuration.
i.e.:
#Bean
public StringHttpMessageConverter stringMessageConverter() {
return new StringHttpMessageConverter();
}
#Override
public void configureMessageConverters(List<HttpMessageConverter<?>> converters) {
converters.add(jacksonConverter());
converters.add(stringMessageConverter());
}

The problem seems to be, that you are creating with this part manager m = new manager(); You should autowire your manager class into your controller to make it work. If you debug your program, you should see, that manager is null. A good answer is here: Why is my Spring #Autowired field null?
