java.lang.IllegalAccessError : org. apache.commons.dbcp.DelegatingPreparedStatement.isClosed()Z

Question

我尝试将 spring 和 mybatis 集成。

jdk:1.8

运行我的测试:

    @Test
    public void testFindUserById() throws Exception{
        UserMapper userMapper=(UserMapper)applicationContext.getBean("userMapper");
        User user=userMapper.findUserById(1);
        System.out.println(user);
    }

和错误:the full stacktrace

java.lang.IllegalAccessError: org.apache.commons.dbcp.DelegatingPreparedStatement.isClosed()Z

spring配置文件:

    <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"
        destroy-method="close">
        <property name="driverClassName" value="com.mysql.jdbc.Driver" />
        <property name="url" value="jdbc:mysql://localhost:3306/custom?useSSL=false" />
        <property name="username" value="root" />
        <property name="password" value="qqwe5631652" />
        <property name="maxIdle" value="5" />
    </bean>

    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource" />
        <property name="configLocation" value="classpath:SqlMapConfig.xml" />

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

    <bean id="userDao" class="dao.UserDaoImpl">
        <property name="sqlSessionFactory" ref="sqlSessionFactory" />

    </bean>
</beans>

我把 commons-dbcp-1.2.1.jar 改成 commons-dbcp-1.4.jar ，现在可以了!
