Junit 使用方法

1、pom.xml中引入需要的jar

注：建议spring-Test.jar在pom.xml 文末引入，我在最前面引入报错，说是缺少jar,这点事需要注意的

<dependency><groupId>junit</groupId><artifactId>junit</artifactId><version>4.12</version></dependency><dependency>              <groupId>org.springframework</groupId>              <artifactId>spring-test</artifactId>              <version> 3.2.4.RELEASE  </version>              <scope>provided</scope>          </dependency>

2、写Junit基类，别的类通过继承此类调用

package com.loan.util;import org.junit.runner.RunWith;import org.springframework.test.context.ContextConfiguration;import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;@RunWith(SpringJUnit4ClassRunner.class)//注入bean@ContextConfiguration("classpath:/application-context.xml")public class BaseJunit {}

3、书写测试类

package com.loan.back.controller;import javax.annotation.Resource;import org.junit.Test;import com.loan.security.service.ResourceService;import com.loan.util.BaseJunit;public class JunitTest extends BaseJunit{@Resourceprivate ResourceService resourceService;@Testpublic void load(){System.out.println(resourceService.load((long)8).toString());}}

4、运行方式

鼠标放置到需运行的方法（load）上，然后右键run as -> JUnit Test即可

Controller测试：

@Controller@RequestMapping("/admin/resource")public class ResourceController extends BaseJunit{@javax.annotation.Resourceprivate ResourceService resourceService;@javax.annotation.Resourceprivate RoleResourceService roleResourceService;@Test@RequiresPermissions("resource:view")@RequestMapping(value="/list", method = RequestMethod.GET)public void load(){System.out.println(resourceService.load((long)8).getPic());}}

至此，成功！
