SpringMVC Junit4测试 "No ServletContext set"

讲真搞了一整天,虽然知道引发错误的是什么,但不能不使用它.

看下这个：https://stackoverflow.com/questions/48367588/spring-boot-with-aclpermissionevaluator-resulting-in-illegalstateexception-no-s

额柳暗花明又一村 ,
刚准备关闭问题就找到了解决方案

@RunWith(SpringJUnit4ClassRunner.class)
@WebAppConfiguration
@ContextConfiguration(locations = { "classpath:applicationContext.xml","classpath:springmvc-servlet.xml" })
public class MybatisTest {
    //Test methods
}

一开始测试方向就错了应该是测试 web context 所以需要使用注解

@WebAppConfiguration("src/main/resources") : 注解在类上,用来声明加载的ApplicationContex 是一个WebApplicationContext ,它的属性指定的是Web资源的位置,默认为 src/main/webapp ,自定义修改为 resource
这下能混合测试了。

补充问题时被封号了........

如果不进行测试(没有测试用例)则可以正常运行,由此可推出 Junit 没有生成 ServletContext

MyTest.java

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = { "classpath:springmvc-servlet.xml"  })
public class MyTest {

    @Resource
    TestService ts;
    @Test
    public void testSelect() {
        System.out.println("■■■■T■■■E■■■S■■■T■■■C■■■O■■N■■■S■■■O■■■L■■■E■■■■");
        System.out.println();
        System.out.println(ts.test());
        System.out.println();
        System.out.println("■■■■T■■■E■■■S■■■T■■■E■■■N■■D■■■I■■■N■■■G■■■!■■■■");
    }
}

Service实现类,接口就不贴了

@Service("testService")
public class TestServiceImpl implements TestService {

    @Override
    public String test() {
        return "cow cow";
    }

}

如果Config类没有@EnableWebMvc是正常运行的,也就是说
@EnableWebMvc 与 src/test/java 目录中的类有冲突,没有测试类能编译通过能在Tomcat运行,有测试类则不能用@EnableWebMvc 原因技术有限无法明白
这种情况隐约感觉跟配置或注解有关,拜托了各位

结贴了真是技术有限无法实现 , 若真如此贴所示 Junit无法启动 web容器那也就说的通了,**无法启动也就 no servletContext**
参考 junit能否启动web项目设置的web listener？
