struts2+spring3.0+JPA1.0(hibernate3.3)工程的构建

  构建JPA工程J2EE 5 只支持JPA1.0 ;要构建JPA2.0 要j2EE6 现在支持开源的应用服务器不多 只有glassfish；构建的报需要如下

 

    

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

这些包我不上传了官方都有。（如果觉得有些包比较难找 可以用www.findjar.com搜索）

persistence.xml 中的配置为：

  <persistence-unit name="tcsdatasource" transaction-type="RESOURCE_LOCAL"> 
      <properties> 
       <!-- 数据库方言--> 
       <property name="hibernate.dialect" value="org.hibernate.dialect.MySQLDialect"/>
       <!-- 数据库驱动 --> 
       <property name="hibernate.connection.driver_class" value="com.mysql.jdbc.Driver"/>
       <!-- 数据库用户名 --> 
       <property name="hibernate.connection.username" value="admins"/> 
       <!-- 数据库密码 --> 
       <property name="hibernate.connection.password" value="root"/> 
       <!-- 数据库连接URL --> 
       <property name="hibernate.connection.url"
             value="jdbc:mysql://10.6.0.6:3306/tcscloud?useUnicode=true&amp;characterEncoding=UTF-8"/> 
       <!-- 最大抓取深度 --> 
       <property name="hibernate.max_fetch_depth" value="3"/>
       <!-- 更新方式创建库表 -->
       <property name="hibernate.hbm2ddl.auto" value="update"/>
       <!-- 显示SQL --> 
       <property name="hibernate.show_sql" value="true"/> 
       <!-- 格式SQL --> 
       <property name="hibernate.format_sql" value="true"/>
       

      </properties> 
 </persistence-unit> 

 

spring 的配置文件如下：

   <context:annotation-config/> 
   
    <bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalEntityManagerFactoryBean"> 
      <property name="persistenceUnitName" value="tcsdatasource"/> 
    </bean> 
   
    <bean id="txManager" class="org.springframework.orm.jpa.JpaTransactionManager"> 
      <property name="entityManagerFactory" ref="entityManagerFactory"/> 
    </bean> 
   
    <tx:annotation-driven transaction-manager="txManager"/>

 

struts 配置文件（实现了自定意拦截器）：

<struts>
 <constant name="dev.model" value="true" />
 <constant name="struts.i18n.encoding" value="UTF-8"></constant>
 <constant name="struts.convention.default.parent.package" value="project-default" /> <!--设置默认的包-->
  <constant name="struts.convention.package.locators" value="action" />
 
 <package name="project-default" extends="convention-default">
   
  <!--拦截器配置-->
  <interceptors>
  
      <!--登录拦截器-->
   <interceptor name="loginInterceptor"  <!--spring 配置文件自定意的类-->
    class="loginInterceptor">
   </interceptor>
   
   <!--权限拦截器-->
   <interceptor name="permissionInterceptor"  <!--spring 配置文件自定意的类-->
       class="permissionInterceptor">
   </interceptor>
      
   <interceptor-stack name="loginDefaultStack">
    <interceptor-ref name="loginInterceptor"></interceptor-ref>
    <interceptor-ref name="permissionInterceptor"></interceptor-ref>
    <interceptor-ref name="defaultStack"></interceptor-ref>
   </interceptor-stack>
  </interceptors>
  
  <default-interceptor-ref name="loginDefaultStack"></default-interceptor-ref>
  
  <!--全局返回配置-->
  <global-results>
   <result name="error">/pages/common/error.jsp</result>
   <result name="sessionTimeout">/pages/common/sessiontimeout.jsp</result>
  </global-results>
 </package>
 

</struts> 

  

 

DAO的EntityManager 注入：

 /**
 *@see 框架测试的Dao
 *@author desert
 *@version 1.0
 */
public class TestDaoImpl implements TestDao{
 
   @PersistenceContext
   private EntityManager em; 
 
 public void saveTest(TestBean testBean){
    this.em.persist(testBean);
 }

    ....................

}
 

 

事务处理的DEMO:

 @Transactional
public class TestServiceImpl implements TestService{
 
 @Resource
 private TestDao testDao;
 
 @Transactional(propagation = Propagation.REQUIRED) 
 public TestBean getTestBeanById(int id){
   
    return this.testDao.getTestById(id);
 }
 
 // @Transactional(propagation = Propagation.REQUIRED) 
 public void  removeTestBean(TestBean testBean){
   this.testDao.removeTest(testBean);
 }
 
 // @Transactional(propagation = Propagation.REQUIRED)  
 public void  saveTestBean(TestBean testBean)throws Exception{
  try{
    this.testDao.saveTest(testBean);
    this.testDao.getTestBeanList();
  }catch(Exception e){
   throw new TcsException(e.getMessage());
  }
 }
 
 @Transactional(propagation = Propagation.NOT_SUPPORTED) 
 public List<TestBean> getTestBeanList()throws Exception{
  List<TestBean>  list = null;
     list = this.testDao.getTestBeanList();
  return list;
 }
 

}

 

测试代码编写：

   /**
 *@see 框架测试的Junit
 *@author desert
 *@version 1.0
 */
public class JunitTest {
 
  private static TestService  testService;
 
  @BeforeClass 
  public static void setUpBeforeClass() throws Exception {  
        try {  
             ApplicationContext applicationContext = new ClassPathXmlApplicationContext(new String[]{"applicationContext-service.xml","/springconfig/*-service.xml"});  
             testService = (TestService) applicationContext.getBean("testService");  
         } catch (RuntimeException e) {  
             e.printStackTrace();  
         }  
     }  
  
     @Test 
     public void testSave()throws Exception{   
     

     }  
  
     @Test 
     public void testUpdate() {  
       
     }  
  
     @Test 
     public void testGetById() {  
      /*TestBean object = this.testService.getTestBeanById(1);
      System.out.println(object.getUserName()+" "+object.getPassword());*/
     }  
  
     @Test 
     public void testDelete() {  
         
     }  
  
     @Test 
     public void testGetList()throws Exception{
      List<TestBean> testBean_list = testService.getTestBeanList();
       for(TestBean object:testBean_list){
        System.out.println(object.getUserName()); 
       }
       
     }  
}

struts2 注解demo：

/**
 *@see 框架测试的TestAction(测试通过)
 *@author desert
 *@version 1.0
 */
@ParentPackage("project-default")  //可以省略不写（设置了默认）
@Namespace("/test")  //为了维护方便必须写
@Results({
  @Result(name="success",location="/pages/common/sessiontimeout.jsp"),
  @Result(name="index",location="/pages/common/error.jsp")
})
public class TestAction extends BaseAction{
 
 private static final long serialVersionUID = 1L;
 
 @Resource
    private TestService  testService;
 
 public String forwardIndex()throws Exception{
   testService.getTestBeanList();
   return "index";
 }

}

 

TestAction 去掉Action 并且第一个字母小写得到test做为Action类的访问名

访问路径为：http://工程名/test/test!forwardIndex.action
