Mybatis动态sql----if--where

当使用Map做为参数和pojo作参数时，两者配置文件写法相同

     
    select * from user
    
    
    and username like '%${username}%' 
    
    
    
    and sex=#{sex} 
    
    
    
    and address like '%${address}%' 
    
    
     
    ```

select * from user


and username like '%${username}%' 



and sex=#{sex} 



and address like '%${address}%'
