User.xml


。。。

select uid,uname,upasswd,email,ustat,uface,uintro,uexp,urmb,active,gender from User

package com.ssm.bbs.dao.UserDao
public interface UserDao {
public List queryList();
}

这个错误的原因是，我在其他mapper.xml中错写了一个resultMap="java.util.Map" 改成resultType就不报错了。
但是有一个新的错误：

 Error querying database.  Cause: java.lang.IllegalArgumentException: Mapped Statements collection does not contain value for com.ssm.bbs.dao.UserDao
### Cause: java.lang.IllegalArgumentException: Mapped Statements collection does not contain value for com.ssm.bbs.dao.UserDao] with root cause
java.lang.IllegalArgumentException: Mapped Statements collection does not contain value for com.ssm.bbs.dao.UserDao

我已经检查过了，我的接口全名和mapper的namespace是一致的，接口名和mapper的文件名也是一致的，但还是有问题

//替换成下面的
<select id="queryList" resultMap="Map">
    select uid,uname,upasswd,email,ustat,uface,uintro,uexp,urmb,active,gender from User
</select>

    //Model对象和数据库表对象映射resultMap是不是没有加
//type写成你的User类，包含包名和类名：如com.model.User
<resultMap id="userMap" type="com.model.User" >
        <!--column对应数据库字段名，property对应User对象属性名，一一对应好-->
        <id column="ID" property="uid"/>
        <!--其他字段-->
    </resultMap>
    <select id="queryList" resultMap="userMap">
        select uid,uname,upasswd,email,ustat,uface,uintro,uexp,urmb,active,gender from User
</select>

没问题了，就是这

其他mapper.xml中错写了一个resultMap="java.util.Map" 改成resultType就不报错了。

的问题

上面我说的，是我测试类的问题改了就好了。

Result Maps collection does not contain value for java.util.Map
这句话的意思是，你的map中没有value
