IDEA Junit FileNotFoundException: class path resource [spring/spring.xml] cannot be opened because it does not exist

今天打算写一个单元测试,但是已经有写好的单元测试无论怎么弄都提示文件不存在,自己一度以为是启动方式不正确.这里简单记录一下处理过程

1 异常信息:

2 项目目录结构

3 处理方式

　　1. 首先是获取单元测试工作目录

    @Test
    public void demoTest(){
        System.out.println(AccountTest.class.getClassLoader().getResource("").getPath());
    }

　　输出信息:

　　/D:/git/zzlh/guarantee/target/test-classes/

　　2. 然后去这个目录下查找是否有自己的配置文件 -> spring/spring.xml

　　发现确实没有,这时我想到是不是IDEA的原因,之前用eclipse也常是这种因为build path的原因造成文件找不到

　　3 IDEA需要你指定单元测试的resouces目录

　　　　a. 如果你test目录下有resouces目录文件,需要如下操作

　　　　　　确认 test/resources 目录为 [test/resources] --右键--> [Mark Directory as] -->[Test Resources Root]

　　　　b. 如果没有需要添加test的resource目录

　　　　　　File -> Project Structrue... -> Project Settings -> Modules 进行如下配置
