Spring Boot - Large Objects may not be used in auto-commit mode

I have an entity class called ItemType with the following relation:
#OneToMany(orphanRemoval = true,targetEntity = BinaryObjectType.class, cascade = {
javax.persistence.CascadeType.ALL
})
#JoinColumn(name = "PRODUCT_IMAGE_ITEM_TYPE_HJID")
public List<BinaryObjectType> getProductImage() {
if (productImage == null) {
productImage = new ArrayList<BinaryObjectType>();
}
return this.productImage;
}
Then, BinaryObjectType has the following relation:
#Basic
#Column(name = "VALUE_")
#Lob
public byte[] getValue() {
return value;
}
I've created a custom repository in a Spring Boot application just for testing as follows:
package eu.nimble.service.catalogue.config;
#Service
#Transactional(transactionManager = "barTransactionManager")
public class CustomRepo {
#Autowired
#Qualifier("barEntityManager")
private EntityManager em;
public ItemType getItem() {
String query = "SELECT it FROM ItemType it WHERE it.hjid = 147";
Query q = em.createQuery(query);
List<ItemType> i = q.getResultList();
return i.get(0);
}
}
And finally, the DB config has been instantiated as follows:
#Bean(name = "barDataSource")
#ConfigurationProperties(prefix = "persistence.orm.ubl.spring")
public DataSource dataSource() {
return DataSourceBuilder.create().build();
}
#Bean(name = "barEntityManagerFactory")
public LocalContainerEntityManagerFactoryBean barEntityManagerFactory(
EntityManagerFactoryBuilder builder,
#Qualifier("barDataSource") DataSource dataSource) {
LocalContainerEntityManagerFactoryBean emfBean = builder
.dataSource(dataSource)
.persistenceUnit("ubl-data-model")
.build();
return emfBean;
}
#Primary
#Bean(name = "barEentityManagerFactory")
public EntityManagerFactory entityManagerFactory(
#Qualifier("barDataSource") DataSource dataSource,
#Qualifier("barEntityManagerFactory") LocalContainerEntityManagerFactoryBean emfBean) {
return emfBean.getObject();
}
#Bean(name = "barTransactionManager")
public PlatformTransactionManager barTransactionManager(
#Qualifier("barEntityManagerFactory") EntityManagerFactory barEntityManagerFactory) {
return new JpaTransactionManager(barEntityManagerFactory);
}
#Bean(name = "barEntityManager")
public EntityManager entityManager(
#Qualifier("barEentityManagerFactory") EntityManagerFactory emf) {
return emf.createEntityManager();
}
I can retrieve the ItemType instance from the DB but when I return the obtained instance via a REST service (see below), I get the following exception:
Could not write content: Unable to access lob stream (through reference chain: eu.nimble.service.model.ubl.commonaggregatecomponents.ItemType[\"productImage\"]); nested exception is com.fasterxml.jackson.databind.JsonMappingException: Unable to access lob stream (through reference chain: eu.nimble.service.model.ubl.commonaggregatecomponents.ItemType[\"productImage\"])
The complete stack trace is as follows:
org.springframework.http.converter.HttpMessageNotWritableException: Could not write content: Unable to access lob stream (through reference chain: eu.nimble.service.model.ubl.commonaggregatecomponents.ItemType["productImage"]); nested exception is com.fasterxml.jackson.databind.JsonMappingException: Unable to access lob stream (through reference chain: eu.nimble.service.model.ubl.commonaggregatecomponents.ItemType["productImage"])

The REST service is a simple one as follows:
#RequestMapping(value = "/temp",
produces = {MediaType.APPLICATION_JSON_VALUE},
method = RequestMethod.GET)
public ResponseEntity tempMethod() {
ItemType c = repo.getItem();
return ResponseEntity.status(HttpStatus.OK).body(c);
}
So, how can I return the data properly? I already tried to set the hibernate.enable_lazy_load_no_trans to true and hibernate.connection.autocommit to false without success. I also tried to add getCatalogueByUuid to the REST service method (i.e tempMethod) as well as to the repository method i.e. getItem.
Thanks for your helps in advance.

Spark: Streaming DataFrame

I wrote a SpringBoot App that can run as Spark Submit job (Never ending job) giving me an endpoint that I can use to get data from SQLContext. I need to stream data as I get from dataframe. I do the following.
Spring Configuration Class
#Configuration
public class SparkConfiguration {
#Bean
public SparkConf sparkConf(){
return new SparkConf().setAppName("TestApp").setMaster("local[*]");
}
#Bean
public JavaSparkContext sparkContext(final SparkConf sparkConf){
return new JavaSparkContext(sparkConf);
}
#Bean
public SQLContext sqlContext(final JavaSparkContext javaSparkContext){
return new SQLContext(javaSparkContext);
}
Rest Controller Class
#RestController
#RequestMapping("/api")
public class TestResource {
#Autowired
private SQLContext sqlContext;
#GetMapping
#ResponseBody
public void test(HttpServletResponse httpServletResponse) throws
IOException {
DataFrame dataFrame =
sqlContext.sql("SELECT * from TABLE_1").toDF();
PrintWriter writer = httpServletResponse.getWriter();
dataFrame.collectAsList().forEach(row -> {
System.out.println(row);
writer.write(String.valueOf(row.get(0)));
writer.flush();
});
}
}
This works fine!!
But this is not really streaming data.
The moment I do, the below.
dataFrame.collectAsList()
The data get accumulated and then I loop.
Let's say the data is huge (in millions), So I tried to get to the "Row" and push data to writer.
Like this:
#GetMapping
#ResponseBody
public void test(HttpServletResponse httpServletResponse) throws IOException {
DataFrame dataFrame = sqlContext.sql("SELECT * from TABLE_1").toDF();
PrintWriter writer = httpServletResponse.getWriter();
dataFrame.javaRDD().map(new Function<Row, Object>() {
#Override
public Object call(Row row) throws Exception {
writer.write(String.valueOf(row.get(0)));
writer.flush();
return null;
}
}).collect();
}
I get Error:

In Jmeter, how do I test a Map Value?

I'm testing a Spring Web Service with Jmeter. We're also using activiti, but since I'm a newb at both, that's about as far as I can tell. Supposedly, the application is to receive parameters from the request.
However, I hit a snag here (UpdateInbdParams):
private String taskId;
private Map<String, String> vars;
public String getTaskId() {
return taskId;
}
public void setTaskId(String taskId) {
this.taskId = taskId;
}
public Map<String, String> getVars() {
return vars;
}
public void setVars(HashMap<String, String> vars) {
this.vars = vars;
}
I'm supposed to send a string, and a Map. The latter is there so supposedly, we could send any parameters we need later, without modifying the code. But how do I test the latter, like this?
That returns this:
{"vars":null}
For reference, here's part of the code that bugs out:
#RequestMapping(method = RequestMethod.POST)
public UpdateOutbdParams post(Locale locale, UpdateInbdParams model) {
UpdateOutbdParams response = new UpdateOutbdParams();
try{
try{
TaskService taskService = this.processEngine.getTaskService();
Task task = taskService.createTaskQuery().taskId(model.getTaskId()).singleResult();
RuntimeService runtimeService = this.processEngine.getRuntimeService();
/** ERRORS HERE **/
runtimeService.setVariables(task.getExecutionId(), model.getVars());
/** ERRORS END HERE **/
taskService.complete(model.getTaskId());
System.out.println(model.getVars().toString());
System.out.println("Task execution id " + task.getExecutionId());
}catch(Exception ex){
ex.printStackTrace();
System.out.println("Inner catch: "+ex.getMessage());
}
}catch(Exception ex){
ex.printStackTrace();
System.out.println("Outer catch: "+ex.getMessage());
return response;
}
return response;
}
And here's the actual error:
java.lang.NullPointerException

Inner catch: null
So I'm guessing it has something to do with how it (didn't) receive a Map value. Any ideas?
Thanks.

I keep getting an Exception for the below code:
org.springframework.integration.MessageDispatchingException: Dispatcher has no subscribers
#Bean
public MessageChannel topicChannel(){
return new DirectChannel();
}

Cannot Initialize a class using the Singleton Method

I created a class that gets an instance of a Database connection. However I am getting an error saying the calling class is null. I will post my error below.
Now I have a working and non working version of this code. I first just jammed everything into a single class to get it up and running then started to clean it up which is when I ran into issues.
This class "createJobTicket" calls the instance of DataBaseConnectionDAO

You can notice that the following is commented out:
//private java.sql.Connection conn = null;
//private java.sql.Statement stmt = null;
This is because if I my IDE said:
Cannot make a static reference to the non-static field conn
Cannot make a static reference to the non-static field stmt
My DataBaseConnectionDAO looks like the following:
public class DataBaseConnectionDAO {
#Inject
private static Environment env;
private static DataBaseConnectionDAO instance;
// Step 1: JDBC props
String DB_URL = env.getProperty("spring.datasource.url");
String USER = env.getProperty("spring.datasource.username");
String PASS = env.getProperty("spring.datasource.password");
java.sql.Connection conn = null;
java.sql.Statement stmt = null;
private DataBaseConnectionDAO() { }
public static DataBaseConnectionDAO getInstance() {
if (instance == null) {
synchronized (DataBaseConnectionDAO.class) {
if (instance == null) {
instance = new DataBaseConnectionDAO();
}
}
}
return instance;
}
public java.sql.Connection getConnection() throws ClassNotFoundException,
SQLException {
Class.forName("com.mysql.jdbc.Driver");
if (conn == null) {
conn = DriverManager.getConnection(DB_URL, USER, PASS);
}
return conn;

You need to start by understanding what this error message means:
java.lang.NoClassDefFoundError: Could not initialize class com.htd.web.rest.util.createJobTicket
When the JVM loads a class, it will complete any static initialization for that class, i.e. assign any values given to static fields and run any static { ... } blocks. As this involves running Java code, this process may cause an exception to be thrown. If an exception is thrown during a class's static initialization, the class loading will fail. Java will wrap the exception in an ExceptionInInitializerError and throw that. If you make a second attempt to load the same class, Java will flatly refuse to load it, and instead throw a NoClassDefFoundError with message Could not initialize class ....
As this is the error you are seeing, I can only conclude that your createJobTicket class is failing its static initialization, and that the exception stacktrace above is not from the first time you attempt to use the createJobTicket class. If, for example, your application is a web application, try restarting the web application container, trying again and seeing if you get a different error first time around.
The static initialization for your createJobTicket class is the following line:
private static DataBaseConnectionDAO databaseConnection = DataBaseConnectionDAO.getInstance();
So your DataBaseConnectionDAO.getInstance() method must be throwing an exception.
The best way to avoid static initialization issues like this is to avoid static initialization altogether. For example, in the following, we create a method getDatabaseConnection() which sets the databaseConnection field if it hasn't already been set, and additionally calls the DAO to return a JDBC Connection object:
private static DataBaseConnectionDAO databaseConnection;
private static java.sql.Connection getDatabaseConnection() {
if (databaseConnection == null) {
databaseConnection = DataBaseConnectionDAO.getInstance();
}
return databaseConnection.getConnection();
}
public static HSSFWorkbook getWorkbook(HSSFWorkbook workbook, Long id, Environment env){
try{
java.sql.Connection conn = getDatabaseConnection();
// ...
This approach should stop your createJobTicket class from failing to complete static initialization. However, please do not expect your code to immediately start working after doing this. The change above goes no way to fix the exception that causes the static initialization to fail. All it does is to make sure this exception only gets thrown after the class has been statically initialized. If you then attempt to run your code, you should hopefully see the actual exception in your log, instead of the NoClassDefFoundError.
So, why would your DataBaseConnectionDAO.getInstance() method be throwing an exception? My best guess is this:
#Inject
private static Environment env;
A few searches suggest that you can't use Spring to inject values into static fields like this, so perhaps you are getting a NullPointerException trying to look up values in an environment that is null. However, I haven't looked into this fully so I don't guarantee that this actually is the problem.
