mybatis mapper 传入多个参数方法

1、使用 @param注解

import org.apache.ibatis.annotations.Param;
public interface UserMapper {
    User selectUser(@Param("username") String username, @Param("hashedPassword") String hashedPassword);
}

2、mapper xml中使用

<select id=”selectUser” resultType=”User”>
  select id, username, hashedPassword
  from some_table
  where username = #{username}
  and hashedPassword = #{hashedPassword}
</select>
