我应该从哪些方向来看

并不是连不上数据库,是解析xml的时候报错了, 贴mybatis-config.xml看看

https://github.com/lusparioTT/MSN
看DEMO

<?xml version="1.0" encoding="UTF-8"?>  
<!DOCTYPE configuration  
PUBLIC "-//mybatis.org//DTD Config 3.0//EN"  
"http://mybatis.org/dtd/mybatis-3-config.dtd">  
<configuration>  
    <settings>  
        <setting name="cacheEnabled" value="true" />  
        <setting name="lazyLoadingEnabled" value="true" />  
        <setting name="multipleResultSetsEnabled" value="true" />  
        <setting name="useColumnLabel" value="true" />  
        <setting name="useGeneratedKeys" value="false" />  
        <setting name="autoMappingBehavior" value="PARTIAL" />  
        <setting name="defaultExecutorType" value="SIMPLE" /> <!-- BATCH, REUSE -->  
        <setting name="defaultStatementTimeout" value="25000" />  
        <setting name="safeRowBoundsEnabled" value="false" />  
        <setting name="mapUnderscoreToCamelCase" value="false" />  
        <setting name="localCacheScope" value="SESSION" />  
        <setting name="jdbcTypeForNull" value="OTHER" />  
        <setting name="lazyLoadTriggerMethods" value="equals,clone,hashCode,toString" />  
    </settings>  
    <typeAliases>  
        <typeAlias alias="UserEntity"  
            type="com.ssmtest.entity.UserEntity" />  
  
    </typeAliases>  
</configuration>

为啥spring会读取这个xml呢, 这不是spring配置文件呢

spring的配置文件applicationContext.xml里有这个配置

	<!-- define the SqlSessionFactory -->  
    <bean id="sqlSessionFactoryUser" class="org.mybatis.spring.SqlSessionFactoryBean">  
        <property name="dataSource" ref="dataSource" />  
        <property name="configLocation"  
            value="classpath:mybatis-config.xml" />  
    </bean>

把这段删掉

<!DOCTYPE configuration  
PUBLIC "-//mybatis.org//DTD Config 3.0//EN"  
"http://mybatis.org/dtd/mybatis-3-config.dtd">

把声明部分删了报其他的错误了

 org.springframework.beans.factory.xml.XmlBeanDefinitionStoreException: Line 2 in XML document from class path resource [mybatis-config.xml] is invalid; nested exception is org.xml.sax.SAXParseException; lineNumber: 2; columnNumber: 16; cvc-elt.1: 找不到元素 'configuration' 的声明。

这个框架是我从别的地方考来的，还有很多不明白的地方。我先学习下，

昨天我刚刚整好mybatis：

 <!-- Mybatis Spring SqlSessionFactoryBean -->
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource" />
        <property name="typeAliasesPackage" value="com.aebiz.app.test.modules.models" />
    </bean>

    <!-- 注册器查找配置 -->
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="basePackage" value="com.aebiz.app.test.modules.mappers" />
        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory" />
    </bean>

<build>
        <sourceDirectory>src/main/java</sourceDirectory>
        <resources>
            <resource>
                <directory>src/main/java</directory>
                <includes>
                    <include>**/*.xml</include>
                </includes>
                <!-- 是否替换资源中的属性-->
                <filtering>false</filtering>
            </resource>
            <resource>
                <directory>src/main/resources</directory>
                <includes>
                    <include>**/*</include>
                </includes>
                <filtering>true</filtering>
            </resource>
        </resources>

还有把xml 一起打包
