        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

                    </dataSource>
                </environment>
            </environments>
        
        
            <mappers>
                <mapper resource="com/lingerqi/mapper/BookMapper.xml"/>
            </mappers>
        </configuration>
        

          

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

        <?xml version="1.0" encoding="UTF-8"?>
        <beans xmlns="http://www.springframework.org/schema/beans"

            <aop:aspectj-autoproxy/>
        </beans>

        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:
