SpringMVC 整合Mybatis 启动tomcat时报错
现在有时间就搞了一个小的权限管理系统，以前用的是springmvc的框架，现在又加上了mybatis之后，就启动tomcat出现错误
在spring配置文件内加上这个配置就启动报错，不加就没问题：
<!-- mapper扫描器 -->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="basePackage" value="com.popedom.mapper"></property>
<property name="sqlSessionFactoryBeanName" value="sqlSessionFactory" />
</bean>
请问各位大牛是什么原因，现在百思不得其解。报错如下：
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'userLoginMapperCustom' defined in file [F:\soft\apache-tomcat-6.0.35\webapps\popedom\WEB-INF\classes\com\popedom\mapper\UserLoginMapperCustom.class]: Invocation of init method failed; nested exception is java.lang.IllegalArgumentException: org.apache.ibatis.builder.BuilderException: Error parsing Mapper XML.

这是 UserLoginMapperCustom.java 接口：
package com.popedom.mapper;
import java.util.List;
import com.popedom.po.*;
public interface UserLoginMapperCustom {
public List<UserLoginCustom> findUserByUserNameAndPassword(
UsersLoginQueryVo userLoginVo);
}
这是 UserLoginMapperCustom.xml文件
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.popedom.mapper.UserLoginMapperCustom">
<resultMap id="userResultMap" type="UserLoginMapperCustom">
<id column="userid" property="userid" />
<result column="username" property="username" />
<result column="userprop" property="userprop" />
<result column="propid" property="propid" />
</resultMap>
<select id="findUserByUserNameAndPassword" parameterType="com.popedom.po.UsersLoginQueryVo"
resultMap="userResultMap">
SELECT
USERID,USERNAME,USERPROP,PROPID
FROM T_ADM_USER
WHERE
USERID=#{UserLoginCustom.userid}
AND

</select>
</mapper>
到底是个啥问题，跪求！！！！！！！！！！！！！！！！！！！！！！！

你看看你的sqlSessionFactory配置没有。
不是光写在MapperScannerConfigurer这个bean里，还需要你写个bean配置sqlSessionFactory，里面带链接池配置参数和xml文件扫描路径，你这个明显的ClassNotFound是没有找个这个文件映射不了
ascendlin 2015-11-30
sqlSessionFactory

看看你的映射文件里怎么写的。

把扫描包的配置放到springmvc配置文件试试，我记得以前遇到过，要么放到spring配置文件里，要么放到mvc配置文件里。具体在哪个里面不记得了
一点点小无奈 2015-11-26
我的项目结构是这样的。一点点小无奈 2015-11-26
我的UserLoginMapperCustom 这个算是dao的接口类，实现dao的接口是用mybatis的xml文件来实现的。
就是老是报这个错误，请问怎么改呢 ？
一点点小无奈 2015-11-26
我的dao和映射文件是放在同一个包内的，都是放在：com.popedom.mappe包内的，我看网上有些放在一起，有些没有放在一起，跟这个有关系吗 ？ 我怀疑是spring的问题。
a1247041186 2015-11-25
我好像知道原因了 <property name="basePackage" value=""/> value指向的是Dao接口包路径
我之间指向的是映射XML包路径

我也遇到这个问题，楼主解决了吗
