JBoss 7 Spring JPA + Hibernate应用程序：没有事务在进行中
问题内容：
我正在尝试使用JPA和Hibernate和JPA Provider使用Spring 3.2开发一个简单的薪资应用程序。我正在将它部署在JBoss AS
7服务器上。我不断收到以下错误：
16:42:13,811 ERROR [org.apache.catalina.core.ContainerBase.[jboss.web].[default-host].[/PayrollApp].[payrollApp]] (http--127.0.0.1-8080-1) Servlet.service() for servlet payrollApp threw exception: javax.persistence.TransactionRequiredException: no transaction is in progress

我正在使用没有任何 persistence.xml 文件的Spring 3.2 。我的 Spring App Config 文件的相关部分：
<!-- Turn on annotation driven features of spring-->
<mvc:annotation-driven/>
<!--<context:annotation-config />-->
<!--Enable Spring to detect the Controllers and other components automatically and configure them as beans-->
<context:component-scan base-package="com.colenso.payrollapp" />

如您所见，我将提取在 standalone.xml 文件中配置的数据源。
控制器：
@Controller
public class PaySlipController {
@Autowired
HRService hrService;
public PaySlipController() {
}
@RequestMapping("/")
public String showHomePage(Map<String, Object> model) {
Employee employee1;
employee1 = new Employee();
employee1.setFirstName("FN");
employee1.setLastName("LN");
Calendar myDOB = new GregorianCalendar(1965, 6, 15);
employee1.setDateOfBirth(myDOB);
hrService.addEmployee(employee1);
return "home";
}
}
我正在按照本文The type-safe generic DAO pattern中提到的在此处输入链接描述， 这里是所有相关代码： 接口 公共接口GenericDAOInterface {
void add(E entitry);
void remove(E entity);
E findById(K id);
}
实作
public abstract class GenericDAO<E, K> implements GenericDAOInterface<E, K> {
protected Class entityClass;
@PersistenceContext
protected EntityManager entityManager;
public GenericDAO() {
ParameterizedType genericSuperclass = (ParameterizedType) getClass().getGenericSuperclass();
this.entityClass = (Class) genericSuperclass.getActualTypeArguments()[1];
}
@Override
public void add(E entity) {
if (entityManager==null)
System.out.println("Entity Manager Not Initialised!!");
entityManager.persist(entity);
entityManager.flush();
}
@Override
public void remove(E entity) {
entityManager.remove(entity);
}
@Override
public E findById(K id) {
return (E) entityManager.find(entityClass, id);
}
}
接口：
public interface EmployeeDAO extends GenericDAOInterface<Employee, Integer>{
}
实作
@Repository
public class EmployeeDAOImpl extends GenericDAO<Employee, Integer> implements EmployeeDAO{
}
接口：
public interface HRService {
public void addEmployee(Employee employee);
}
实作
@Component
@Transactional(propagation = Propagation.REQUIRED)
public class HRServiceImpl implements HRService{
@Autowired
private EmployeeDAO employeeDao;
@Override
public void addEmployee(Employee employee){
employeeDao.add(employee);
}
}
问题答案：
鉴于使用JTA，对于 persistence.xml 是强制性的。这就是我最终要做的。
我的 persistence.xml
<?xml version="1.0" encoding="UTF-8"?>
<persistence version="2.0" xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd">
<persistence-unit name="myPU" transaction-type="JTA">
<provider>org.hibernate.ejb.HibernatePersistence</provider>
<jta-data-source>java:/jboss/datasources/MySqlDS</jta-data-source>
<exclude-unlisted-classes>false</exclude-unlisted-classes>
<class>com.colenso.payrollapp.persistence.entities.Employee</class>
<properties>
<property name="hibernate.archive.autodetection" value="class"/>
<property name="hibernate.cache.provider_class" value="org.hibernate.cache.NoCacheProvider"/>
<property name="hibernate.hbm2ddl.auto" value="update"/>
<property name="hibernate.current_session_context_class" value="jta"/>
<property name="hibernate.transaction.manager_lookup_class" value="blah blah"/>
<property name="hibernate.dialect" value="org.hibernate.dialect.SQLServerDialect"/>
<property name="hibernate.connection.release_mode" value="after_statement"/>
</properties>
</persistence-unit>
</persistence>
我更改了 Spring Context xml ：
<!--********************DataBase Configurations********************************-->

<jee:jndi-lookup id="datasource" jndi-name="java:jboss/datasources/MySqlDS" resource-ref="false" />
