解决@springboottest注解无法加载src/main/resources目录下文件

解决@springboottest注解无法加载src/main/resources目录下文件

目录结论环境及问题描述问题分析1.首先com.xx.xxx.service.SsoService该类存在2.再看下pom文件的配置3.这个类是在src/main/resources目录下的资源文件里配置

Springboot微服务框架是目前越来越流行的框架,省去了很多繁琐的xml配置。最近新启了个项目,采用SpringBoot框架从头搭建,中间也遇到过各种坑,现在先描述一下 Junit4单元测试之坑吧。

结论

@SpringBootTest注解,只会加载test路径下的资源文件(即xml配置),并不会加载main路径下的资源文件,这点很坑。。。

环境及问题描述

1.SpringBoot版本:2.0.0.RELEASE

2.通过项目入口类启动Application.main() OK,能正常处理web请求

3.启动单元测试,执行测试类

问题分析

1.首先com.xx.xxx.service.SsoService该类存在

并且项目正常启动时,并没有这个错误提示,那肯定是单元测试配置的有问题了,首先检查下相关的配置,@RunWith(SpringRunBpDhdYuREhner.class)使用SpringRunner以便在测试开始的时候自动创建spring的应用上下文,没毛病。

@SpringBootTest(classes = 启动类.class)配置也没问题,网上有讨论说springboot 1.4以下版本,要使用@SpringApplicationConfiguration(classes = 启动类.class),而我的项目版本是2.0,显然这个配置也没毛病。

代码如下:

package com.xx.xxx.activity;

import org.junit.After;

import org.junit.Before;

import org.junit.runner.RunWith;

import org.springframework.boot.test.context.SpringBootTest;

import org.springframework.test.context.junit4.SpringRunner;

import org.springframework.test.context.web.WebAppConfiguration;

/**

* 单元测试基类

*/

@RunWith(SpringRunner.class)

@SpringBootTest(classes = Application.class)

//由于是Web项目,Junit需要模拟ServletContext,因此我们需要给我们的测试类加上@WebAppConfiguration。

@WebAppConfiguration

public class BaseTest

{

@Before

public void init() {

System.out.println("开始测试----------------");

}

@After

public void destory() {

System.out.println("结束测试----------------");

}

}

2.再看下pom文件的配置

引用了对应的test包,也没毛病

org.springframework.boot

spring-boot-starter-test

${springboot.version}

test

3.这个类是在src/main/resources目录下的资源文件里配置

即xml中配置的bean,而src/test下并没有resources目录,莫非是这个原因?于是乎在test目录下创建resources路径,并把xml文件拷贝至test对应的路径下,结果能够正常进行单元测试了,数据也写入到数据库中,终于松了口气 -

准备就此作罢,不想在这个问题上浪费时间了,但是再做考虑,这样做欠妥,毕竟我每次改完xml文件的配置,必须得拷贝到test目录对应的文件夹下,这拷来拷去,并不是最好的解决方案啊,能不能打包时,把src/main/resources的资源文件也拷贝到src/test/resources中?这样就不用手工拷贝了。

答案是:当然有了,看pom.xml配置:

id-web-activity-root

src/main/resources

true

**/*.*

src/test/resources

src/main/resources

这时再去执行单元测试,正常执行,同时test-classes路径下已经有了xml资源配置文件,如下图:

单元测试的坑算是填了,再接着填其他坑吧。。。
