异常就是上面的信息:

下面是配置XML

<bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource"
init-method="init" destroy-method="close">
<property name="driverClassName">
<value>com.mysql.jdbc.Driver</value>
</property>
<property name="url">
<value>jdbc:mysql://localhost:3306/webtest</value>
</property>
<property name="username">
<value>root</value>
</property>
<property name="password">
<value>123456</value>
</property>
<property name="maxActive">
<value>20</value>

<property name="initialSize">
<value>1</value>

<property name="maxWait">

</property>
<property name="removeAbandoned">
<value>true</value>
</property>
<property name="removeAbandonedTimeout">
<value>180</value>
</property>
</bean>


<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="dataSource" />  
</bean>


<bean id="sqlSession" class="org.mybatis.spring.SqlSessionTemplate">
<constructor-arg index="0" ref="sqlSessionFactory" />
</bean>

可以确定是： 

        1.照别人通过的版本更改后测试 还是会出现这个问题 ，所以跟Jar版本的冲突无关

        2.数据源连接正常

我只想知道这个问题的产生的原因？ 采用的其他的方式可以创建SqlSessionFatory成功

Spring的Jar版本 4.3.2 

mybatis是3.4.1

mySql驱动包是5.1.40

mybatis-spring包是 1.3.0

求大神解答下 菜鸟一枚

Answer 1

答案也不是这样的 假如我的SqlSessionFatory Bean 都创建不成功的话， 把Dao层注入到SqlSession也没用的，毕竟SqlSession是SqlSessionFatory的openSession方法创建出来的

Answer 2

回复
注意SqlSessionFactory和SqlSessionFactoryBean不是一个类

Answer 3

<bean id="sqlSession" class="org.mybatis.spring.SqlSessionTemplate">

<constructor-arg index="0" ref="sqlSessionFactory" />

</bean>

这句配置错了，SqlSessionTemplate 需要的是SqlSessionFactory的实例，可以尝试如下配置

<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="basePackage" value="com.XXX" />
<property name="sqlSessionFactoryBeanName" value="accountSqlSessionFactory" />
</bean>
