1.Sping整合Junit4进行单元测试:使用spring-test和Junit4进行单元测试(1)maven依赖:添加spring-test和Junit4 jar包
对于jdk1.7版本,spring4版本,依赖如下:
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>4.12</version>
<scope>test</scope>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-test</artifactId>
<version>3.2.9.RELEASE</version>
</dependency>
对于jdk1.8,spring 5,依赖如下:
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>4.12</version>
<scope>test</scope>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-test</artifactId>
<version>3.2.9.RELEASE</version>
</dependency>
注意:这里的junit和spring-test版本号,否则报错;junit和spring-test之间具有版本对应关系(上面的对应关系是经过多次测试得到的)。
(2)编写单元测试:
package com.shang;
import java.util.List;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4Cla***unner;
import com.alibaba.fastjson.JSON;
import com.shang.pojo.Account;
import com.shang.service.AccountService;
@RunWith(SpringJUnit4Cla***unner.class)
@ContextConfiguration(locations={"classpath:applicationContext.xml"})
public class TestController {
@Autowired
AccountService accountService;
@Test
public void test(){
List<Account> list=accountService.getAll();
System.out.println(JSON.toJSONString(list));
}
}
注意:(1)ContextConfiguration(locations={"classpath:applicationContext.xml"}) 中的applicationContext.xml的存储路径为:src/main/resources
(2)ContextConfiguration(locations={"classpath:applicationContext.xml","其他路径"})中的locations中可以指定多个路径。
2.单元测试中的注释含义:
(1)@RunWith 注释是 Junit 提供的,用来说明此测试类的运行者,这里用了 SpringJUnit4Cla***unner,这个类是一个针对 Junit 运行环境的自定义扩展。
(2)@ContextConfiguration 注释是 Spring test context 提供的,用来指定 Spring 配置信息的来源,支持指定 XML 文件位置或者 Spring 配置类名,这里我们指定 classpath 下的 applicationContext.xml为配置文件的位置。
(3)@Autowired 进行对象的实例化,用来说明测试类是在 Spring 容器中管理的,可以获取容器的 bean进行注入,不用手工获取要测试的 bean 实例了。
3.完整的Spring MVC和单元测试的pom文件如下:

通过以上配置,就可以在spring中进行单元测试了。
4.单元测试配置时的错误
(1)org.springframework.test.context.junit4.SpringJUnit4Cla***unner的解决
原因:依赖的jar包对应的版本不一致。
解决:(1)添加依赖:
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>4.12</version>
<scope>test</scope>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-test</artifactId>
<version>3.2.9.RELEASE</version>
</dependency>
(2)右键根项目—maven—update dependencies.重新更新依赖关系,让工程可以找到最新的依赖。
