java.lang.IllegalStateException: Failed to load ApplicationContext

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。

参考： https://blog.csdn.net/qq_32786873/article/details/56480880

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
