Spring 整合hibernate和mybatis的 applicationContext.xml的配置

Spring整合hibernate的applicationContext.xml配置

注解的整体把握 

1、<context:component-scan base-package="com.eduoinfo.finances.bank.web"></context:component-scan> 作用

Spring 容器初始化的时候，会扫描 com.eduoinfo.finances.bank.web下 标有 (@Component,@Service,@Controller,@Repository) 注解的 类 纳入spring容器管理

在类上 ，使用以***解，实现bean 的声明

@Component 泛指组件，当组件不好归类的时候，我们可以使用这个注解进行标注。

@Service 用于标注业务层组件

@Controller 用于标注控制层组件（如srping mvc的controller,struts中的action）

@Repository 用于标注数据访问组件，即DAO组件

示例：

@Controller
@RequestMapping(value = "/test")
public class TestController {

}

------------------------------------------------------------------------------------------------------------------

在类的成员变量上,使用以***解，实现属性的自动装配

@Autowired : 按类 的 类型进行装配

@Resource (推荐) : 1 如果同时指定了name和type，则从Spring上下文中找到唯一匹配的bean进行装配，找不到则抛出异常

    2. 如果指定了name，则从上下文中查找名称（id）匹配的bean进行装配，找不到则抛出异常 

    3.如果指定了type，则从上下文中找到类型匹配的唯一bean进行装配，找不到或者找到多个，都会抛出异常 

    4.如果既没有指定name，又没有指定type，则自动按照byName方式进行装配；如果没有匹配，则回退为一个原始类型进行匹配，如果匹配则自动装配；

@Resource注解在字段上，这样就不用写setter方法了，并且这个注解是属于J2EE的，减少了与spring的耦合。 

示例：

@Resource
private TestServiceImpl testServiceImpl;
