单元测式ssh 项目 跟spring注角功能的应用

第一步搭建ssh 项目 添加三个框架的支持;
第二步添加注解功能
在spring配制文件中加如下代码

	<!-- 启用注解 -->
	<context:annotation-config />
	<!-- 使用annotation 自动注册bean,并保证@Required,@Autowired的属性被注入 -->
	<context:component-scan base-package="com.*" />

dao层的实现类的类名上面加上代码如下

@Repository("起的别名service跟据该名字找到此类生成实例对像")

service层实现类的类名上面加上代码如下

@Service("别名action层据该名调用")

声明dao接口

 @Resource(name = "dao层的别名")
    private  dao层的接口  别名;

service 层据别名调用接口的方法
如：
 

 别名.dao接口方法

action层 类前面的声名

@Controller(value="actin别名")
@Scope(value="prototype")

action层的方法调用跟service层一样

单元测式

public class UserActionTest  {
    //@Resource(name = "userServiceImpl") //自动装配注入  
    public static UserService userService;
    
    @BeforeClass
    public static void setUpBeforeClass() throws Exception {
        System.out.println("before class");
        ApplicationContext context=new ClassPathXmlApplicationContext("resource/spring/applicationContext.xml");
      userService=(UserService) context.getBean("userServiceImpl");

    }
    @AfterClass
    public static void tearDownAfterClass() throws Exception {
        System.out.println("after class");
    }
}
