通用Mapper配置

1.Maven的Pom.xml文件配置：

com.github.abel533

mapper

${mapper.version}

2.SqlMapConfig.xml文件配置

通用Mapper配置：

        

         interceptor= "com.github.abel533.mapperhelper.MapperInterceptor" >

            

             name= "IDENTITY" value= "MYSQL" />

            

             name= "mappers" value= "com.github.abel533.mapper.Mapper" />

        

3.修改POJO

修改pojo，增加JPA注解

作用是把类名和表名进行映射

类中的属性名和表中的列名映射

4.接下来就可以使用UserMapper了。

private NewUserMapper newUserMapper;

this.newUserMapper.insert(user);

this.newUserMapper.selectOne(param);

Listlist = this.newUserMapper.select(param);

int count = this.newUserMapper.selectCount(null);

User user = this.newUserMapper.selectByPrimaryKey(1l);

this.newUserMapper.insertSelective(user);

this.newUserMapper.delete(param);

this.newUserMapper.updateByPrimaryKey(user);

this.newUserMapper.updateByPrimaryKeySelective(user);

this.newUserMapper.delete(param);
