摘要
在配置spring aop的时候总是出现下面的错误,找了很多种办法,这篇文字给了自己点灵感,通过这种方式解决了。

解决办法
Note that the Java 8 bytecode level (-target 1.8, as required by -source 1.8) is only fully supported as of Spring Framework 4.0. In particular, Spring 3.2 based applications need to be compiled with a maximum of Java 7 as the target, even if they happen to be deployed onto a Java 8 runtime. Please upgrade to Spring 4 for Java 8 based applications.
大概的意思就是java1.8版本只支持spring4.0以上。所以解决方法有2中①把sping版本换成4.0以上②把jdk调低点。

spring 整合junit
package com.sp.demo; import org.junit.Test; import org.junit.runner.RunWith; import org.springframework.test.context.ContextConfiguration; import org.springframework.test.context.junit4.SpringJUnit4ClassRunner; import javax.annotation.Resource; @RunWith(SpringJUnit4ClassRunner.class) @ContextConfiguration("classpath:applicationContext.xml") public class OrderDaoTest { @Resource(name = "orderDao") private OrderDao orderDao; @Test public void run() { // ApplicationContext context = new ClassPathXmlApplicationContext("applicationContext.xml"); // orderDao = (OrderDao) context.getBean("orderDao"); this.orderDao.save(); this.orderDao.find(); } }

我使用的是IDE是Idea,可以通过下面的方式进行修改
File->Project Structure->Project
修改为
到此解决
