Mybatis传递多个参数的解决办法(三种)

Public User selectUser(String name,String area);

select * from user_user_t where user_name = #{0} and user_area=#{1}

Public User selectUser(Map paramMap);

select * from user_user_t where user_name = #{userName，jdbcType=VARCHAR} and user_area=#{userArea,jdbcType=VARCHAR}

Private User xxxSelectUser(){
Map paramMap=new hashMap();
paramMap.put(“userName”,”对应具体的参数值”);
paramMap.put(“userArea”,”对应具体的参数值”);
User user=xxx. selectUser(paramMap);}

Public User selectUser(@param(“userName”)Stringname,@param(“userArea”)String area);

select * from user_user_t where user_name = #{userName，jdbcType=VARCHAR} and user_area=#{userArea,jdbcType=VARCHAR}
