数据库查询结果无法封装到com.entity.User。entity.xml再检测仔细点!

把你的user代码和数据库表贴出来看看

把你的user代码和数据库表贴出来看看

package com.entity;

	public int getId() {

	public void setPassword(String password) {

create table USERS

javaType=”java.lang.Integer” jdbcType=”INTEGER”   这段代码去掉试试

去掉也不行,一样的异常

Mapped Statements collection does not contain value for后面是什么类什么方法之类的: 
错误原因有几种: 
1、mapper.xml中没有加入namespace 
2、mapper.xml中的方法和接口mapper的方法不对应 
3、mapper.xml没有加入到mybatis-config.xml中(即总的配置文件),例外:配置了mapper文件的包路径的除外 
4、mapper.xml文件名和所写的mapper名称不相同。

都不符合

感觉是
<select id=”queryAllUser” resultMap=”user“>
        select * from users
    </select>
这里的user没有配置
