hibernate - JBoss 7 Spring JPA + Hibernate 应用程序 : no transaction is in progress

Question

我正在尝试使用 JPA 和 Hibernate 以及 JPA 提供程序使用 Spring 3.2 开发一个简单的薪资应用程序。我将其部署在 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:

    <mvc:annotation-driven/>
    <!--<context:annotation-config />-->

    </bean>
    <tx:annotation-driven />
    <tx:jta-transaction-manager />

如您所见，我正在提取在 standalone.xml 文件中配置的数据源。

Controller :

@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";
    }
}

我遵循本文中提到的类型安全的通用 DAO 模式 enter link description here这是所有相关代码:界面 公共(public)接口(interface) GenericDAOInterface {

void add(E entitry);

void remove(E entity);

E findById(K id);

实现

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(interface):

public interface EmployeeDAO extends GenericDAOInterface<Employee, Integer>{

}

实现

@Repository
public class EmployeeDAOImpl extends GenericDAO<Employee, Integer> implements EmployeeDAO{

}

接口(interface):

public interface HRService {

    public void addEmployee(Employee employee);
}

实现

@Component
@Transactional(propagation = Propagation.REQUIRED)
public class HRServiceImpl implements HRService{

    @Autowired
    private EmployeeDAO employeeDao;


    @Override
    public void addEmployee(Employee employee){
        employeeDao.add(employee);
    }

}

Answer 1

我设法根据这个 Question 的答案找到了我的问题的解决方案

假设要使用 JTA，它是 persistence.xml 所必需的。这就是我最终所做的。

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>

我更改的Spring Context xml:

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