spring中junit 提示Failed to load ApplicationContext

错误提示: 1:java.lang.IllegalStateException: Failed to load ApplicationContext

    2:Error creating bean with name ‘userService‘ defined in class path resource [UserService.xml]: Initialization of bean failed; nested exception is org.springframework.aop.framework.AopConfigException: Cannot proxy target class because CGLIB2 is not available. Add CGLIB to the class path or specify proxy interfaces.

    3:Cannot proxy target class because CGLIB2 is not available. Add CGLIB to the class path or specify proxy interfaces.

根本原因:由于web在加载spring的配置文件(applicationContext.xml)时,发生了错误,而错误是3(cglib2不可用),所以根本原因是缺少cglib的包。

 

applicationContext.xml中的代理配置如下

  <!-- 指定使用cglib -->
    <aop:aspectj-autoproxy proxy-target-class="true" />
    
    <tx:advice id="txAdvice" transaction-manager="transactionManager">
        <tx:attributes>
            <tx:method name="*" />
        </tx:attributes>
    </tx:advice>
    <!-- 通过AOP配置提供事务增强,让service包下所有bean的所有方法拥有事务 -->
    <aop:config proxy-target-class="true">
        <aop:pointcut id="serviceMethod" expression=" execution(* com.luxl.service..*(..))" />
        <aop:advisor pointcut-ref="serviceMethod" advice-ref="txAdvice" />
    </aop:config>

解决方法:在maven中添加cglib的包,如下:

  <dependency>
        <groupId>cglib</groupId>
        <artifactId>cglib</artifactId>
        <version>2.2.2</version>
    </dependency>
