急！！SSM项目出现错误！文档根元素 "beans" 必须匹配 DOCTYPE 根 "null"。

Question

添加!DOCTYPE的方法行不通，
版本应该也没问题
文件名也没问题
就是出不来，新建了项目，配置文件换了两种写法，改了好多次，结果都是一样的错误
请大家帮我看看代码错在哪啊
首先是测试文件

package com.yangquan.test;

import com.yangquan.dao.OusersMapper;
import com.yangquan.domin.Ousers;
import org.apache.ibatis.io.Resources;
import org.apache.ibatis.session.SqlSession;
import org.apache.ibatis.session.SqlSessionFactory;
import org.apache.ibatis.session.SqlSessionFactoryBuilder;
import org.springframework.context.annotation.ImportResource;
import org.springframework.context.support.ClassPathXmlApplicationContext;

import java.io.IOException;
import java.io.InputStream;

public class t2 {

    public static void main(String[] args){
        InputStream inputStream = null;
        try {

            inputStream = Resources.getResourceAsStream("springApplication.xml");
        }catch (IOException e){
            e.printStackTrace();
        }
        SqlSessionFactory build = new SqlSessionFactoryBuilder().build(inputStream);
        SqlSession sqlSession = build.openSession();
        OusersMapper ousersMapper = sqlSession.getMapper(OusersMapper.class);
        Ousers ousers = (Ousers) ousersMapper.selectAll();
        System.out.println(ousers);
        sqlSession.close();



    }
}

然后是配置文件springApplication.xml

<?xml version="1.0" encoding="utf-8" ?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

        <!-- 当获取连接失败重试次数 -->
        <property name="acquireRetryAttempts" value="${acquireRetryAttempts}"/>
    </bean>
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <!--注入我们的数据源 -->
        <property name="dataSource" ref="dataSource">

        <!--扫描mapper配置文件中的.xml文件-->
        <property name="mapperLocations" value="classpath*:com/yangquan/mapper/*.xml"/>
        <!--设置别名-->

    </bean>

</beans>

mapper的映射文件和配置文件是自动生成的，应该没错。
网上能试的方法都试过了，但都没用，求各位帮忙找找错误在哪里

Answer 1

你用spring的配置文件去启动mybatis？人才啊
