    1. mybatis与spring集成

      1、Mybatisspring集成

      2、Aop整合pagehelper插件

       

      Mybatisspring集成

       

      1、导入pom依赖

        注:使用mybatis-generator插件,pom文件添加支持

      4、Spring Test+junit组合

       

      1、在工程的pom文件中增加spring-test的依赖

       

           <dependency>
      
      
             <groupId>org.springframework</groupId>
      
      
             <artifactId>spring-test</artifactId>
      
      
             <version>${spring.version}</version>
      
      
           </dependency>
      

       2、 创建BaseTestCase,并在该类上加上两个注解

         @RunWith(SpringJUnit4ClassRunner.class)

         @ContextConfiguration(locations={"classpath:applicationContext.xml"})

      相关代码:

      Aop整合pagehelper插件

       

      注意:记得开动态代理

       

      使用AOP编程解决分页代码重复的问题

         @Around("execution(* *..*Service.*pager(..))")

      语法结构:execution(方法修饰符  方法返回值  方法所属类 匹配方法名 (  方法中的形参表 )  方法申明抛出的异常  )

      "*"  :代表一个任意类型的参数;

      ..”:代表零个或多个任意类型的参数。
