Any help is greatly appreciated!!
Thanks!!!
AbstractItemCountingItemStreamItemReader implementations aren't thread-safe. You can try to solve it implementing your own reader and synchronizing methods that mutate shared state like close(), open() and update().

HijackAroundMethod.java

public class HijackAroundMethod implements MethodInterceptor
{
public Object invoke(MethodInvocation methodInvocation) throws Throwable {
System.out.println("Method name : "

System.out.println("Method arguments : "

//same with MethodBeforeAdvice
System.out.println("HijackAroundMethod : Before method hijacked!");

System.out.println("HijackAroundMethod : Before after hijacked!");
return result;
}catch(IllegalArgumentException e){
//same with ThrowsAdvice
System.out.println("HijackAroundMethod : Throw exception hijacked!");
throw e;
}
}
}
App.java
package com.mkyong;
import org.springframework.batch.core.Job;
import org.springframework.batch.core.JobExecution;
import org.springframework.batch.core.JobParameters;
import org.springframework.batch.core.launch.JobLauncher;
import org.springframework.batch.item.ExecutionContext;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
public class App {
public static void main(String[] args) {
String[] springConfig =
{
"Spring-Customer.xml"
};
ApplicationContext context =
new ClassPathXmlApplicationContext(springConfig);
JobLauncher jobLauncher = (JobLauncher) context.getBean("jobLauncher");
Job job = (Job) context.getBean("helloWorldJob");
try {
JobExecution execution = jobLauncher.run(job, new JobParameters());
ExecutionContext executionContext = execution.getExecutionContext();
executionContext.put("Test", "Test String");
System.out.println("Exit Status : " + execution.getStatus());
} catch (Exception e) {
e.printStackTrace();
}
System.out.println("Done");
}
}
So when the execution.getExecutionContext() method is called then it must call the invoke method in HijackAroundMethod class, but somehow it doesn't work like that.
I'm currently trying to get Spring Data JPA to work with two DataSources and thus two EntityManagers. My Repositories all inherit from a custom base class "BaseRepositoryImpl".
Problem:
I always get the following exception:
org.springframework.beans.factory.NoSuchBeanDefinitionException:
No unique bean of type [javax.persistence.EntityManagerFactory] is defined:
expected single bean but found 2: entityManagerFactory1,entityManagerFactory2
Question:
How can I tell my custom RepositoryFactory which EntityManagerFactory to use?
Here's my Spring configuration:
<jpa:repositories base-package="package1" transaction-manager-ref="..."
factory-class="MyFactoryBean"
entity-manager-factory-ref="entityManagerFactory1"/>
<bean id="dataSource1" class="org.springframework.jndi.JndiObjectFactoryBean">
<property name="jndiName" value="..." />
</bean>
<bean id="entityManagerFactory1" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
<property name="dataSource" ref="dataSource1" />
<property name="persistenceUnitName" value="unit1" />
...
</bean>
<jpa:repositories base-package="package2" transaction-manager-ref="..."
factory-class="MyFactoryBean"
entity-manager-factory-ref="entityManagerFactory2"/>
<bean id="dataSource2" class="org.springframework.jndi.JndiObjectFactoryBean">
<property name="jndiName" value="..." />
</bean>
<bean id="entityManagerFactory2" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
<property name="dataSource" ref="dataSource2" />
<property name="persistenceUnitName" value="unit2" />
...
</bean>
The class "MyFactoryBean" is implemented exactly as described at http://docs.spring.io/spring-data/jpa/docs/1.4.x/reference/htmlsingle/#repositories.custom-behaviour-for-all-repositories.
The configuration "entity-manager-factory-ref" seems to be ignored by Spring, at least when using a custom RepositoryFactory.
Any hints?
Entity manager factory is used to create entity managers for different persistence units. You declare your entity manager bean and then give entity manager factory bean as it's class.
This is what worked for me:
<tx:annotation-driven transaction-manager="transactionManager" />
<bean class="org.springframework.orm.jpa.support.PersistenceAnnotationBeanPostProcessor"/>
<bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager">
<property name="entityManagerFactory" ref="defaultEntityManager"/>
</bean>
<bean id="defaultDataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
<property name="driverClassName" value="${hibernate.connection.driver_class}"/>
<property name="url" value="${db.default.url}"/>
<property name="username" value="${db.default.username}"/>
<property name="password" value="${db.default.password}"/>
</bean>
<bean id="defaultEntityManager" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
<property name="dataSource" ref="defaultDataSource"/>
<property name="persistenceUnitName" value="defaultPersistenceUnit"/>
</bean>
<bean id="otherDataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
<property name="driverClassName" value="${hibernate.connection.driver_class}"/>
<property name="url" value="${db.other.url}"/>
<property name="username" value="${db.other.username}"/>
<property name="password" value="${db.other.password}"/>
</bean>
<bean id="otherEntityManager" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
<property name="dataSource" ref="otherDataSource"/>
<property name="persistenceUnitName" value="otherPersistenceUnit"></property>
</bean>
Then when you are implementing your data access classes just declare:
#Repository
#Transactional
public class MyDAOImpl implements MyDAO
{
#PersistenceContext(unitName = "defaultPersistenceUnit")
private EntityManager entityManager;
}
and for DAO that uses other persistence unit:
#Repository
#Transactional
public class MyOtherDAOImpl implements MyOtherDAO
{
#PersistenceContext(unitName = "otherPersistenceUnit")
private EntityManager entityManager;
}
I am trying to update the user_info table with the new password using EntityManager.merge(), but it is not getting committed. Below is my code:

Here is my DAO
public class ForgetPasswordDAO {
private Vector loginResult = null;
private int resultTrue = 1;
private int resultFalse = 0;
protected EntityManager entityManager;
JpaEntityManager jpaEntityManager;
public ForgetPasswordDAO() {
}
public EntityManager getEntityManager() {
return entityManager;
}
public void setEntityManager(EntityManager entityManager) {
this.entityManager = entityManager;
}
public Integer fetchUser(ForgetPasswordModel model) throws Exception {
try {
ForgetPasswordDTO DTO ;
if(model == null) {
throw new Exception("102");
}
Integer result = 0;
String userName = model.getUser_id();
String dob = model.getDob();
System.out.println("UserDTO " + model.getUser_id() + " "
+ model.getDob());
ForgetPasswordModel forgetModel = null;
System.out.println(entityManager.isOpen()+">>");
forgetModel = entityManager.find(ForgetPasswordModel.class, model.getUser_id());
entityManager.close();
System.out.println("UserDAO " + forgetModel.getUser_id() + " DOB "
+ forgetModel.getDob()+" EMAIL_ID "+forgetModel.getEmail_id()+" PASSWORD "+forgetModel.getPasswd());
if(model.getDob().equals(forgetModel.getDob())) {
System.out.println("USER VALID , CAN PROCEED WITH PASSWORD RESET");
String passwd = GenerateRandomPassword.generateRandomPassword();
System.out.println("generated password is" +passwd);
entityManager.getTransaction().begin();
forgetModel.setPasswd(passwd);
entityManager.merge(forgetModel);
entityManager.getTransaction().commit();
System.out .println("updated password is "+forgetModel.getPasswd());
String email=forgetModel.getEmail_id();
ForgetPasswordSendMail.SendMail( email, passwd);
result=1;
}
else
{
System.out.println("USER InVALID , Please Provide Valid Data");
}
return result;
} catch (Exception e) {
throw new Exception("103", e);
}
}
}
When I run the above code I get the following error:

Since you are using Spring, you need to use Spring transactions, not JPA transactions.
You need to declare the transaction in Spring, or access the EntityManager directly, not through Spring.
