  • 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

    2、利用mybatis逆向工程生成模型层层代码

    generatorConfig.xml:

                <!-- 建立的Model对象是否 不可改变  即生成的Model对象不会有 setter方法,只有构造方法 -->
                <property name="immutable" value="false"/>
            </javaModelGenerator>
    
            <!-- 02 指定sql映射文件生成的位置 -->

            </javaClientGenerator>
    
            <!-- 配置表信息 -->

            <!--<!– 忽略列,不生成bean 字段 –>-->

            </table>
    
        </context>
    </generatorConfiguration>
    

     

      mybatis.cfg.xml:

    <?xml version="1.0" encoding="UTF-8"?>
    <!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN" "http://mybatis.org/dtd/mybatis-3-config.dtd">

    3、编写配置文件applicationContext-mybatis.xml

    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(..))")

       public Object invoke(ProceedingJoinPoint args)

     

    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。
