错误
SpringBoot项目，单元测试的时候，报错：
java.io.FileNotFoundException: Could not open ServletContext resource [/config.properties]
测试代码：
@Test public void testGetCreditListByPost(){ String result=creditService.getCreditListByPost("XX公司"); log.info(result); }
完整报错：

原因
这个原因不是config.properties配置找不到，而是项目中存在@PropertySource注解 。
@PropertySource("config.properties")
解决办法
将
@PropertySource("config.properties")
替换成：
@PropertySource("classpath:config.properties")
OK，问题解决。
