Parameter 'id' not found. Available parameters are [id , param1]
MyBatis传入参数时，报错Parameter ‘id’ not found. Available parameters are [id , param1]
解决办法：
1.删除Mapper接口中的@Param(“param”）
public int add2(@Param("articleInfo") ArticleInfo articleInfo);
public int add( ArticleInfo articleInfo);//对象
public int updateTitle(@Param("id") Integer id ,@Param("title") String title);//普通的变量
2.xml中写成 #{param.xxx}
insert into articleinfo(title,content,uid)
values(#{articleInfo.title},#{articleInfo.content},#{articleInfo.uid})
insert into articleinfo(title,content,uid)
values(#{title},#{content},#{uid})
update articleinfo set title=#{title} where id=#{id}
普通的变量不用像类的属性那样访问
