Spring Junit 单元测试@Test 报错 ServletContext找不到

No qualifying bean of type [javax.servlet.ServletContext] found for dependency)

报错日志信息

Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [javax.servlet.ServletContext] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {} at org.springframework.beans.factory.support.DefaultListableBeanFactory.raiseNoSuchBeanDefinitionException(DefaultListableBeanFactory.java:1100) at org.springframework.beans.factory.support.DefaultListableBeanFactory.doResolveDependency(DefaultListableBeanFactory.java:960) at org.springframework.beans.factory.support.DefaultListableBeanFactory.resolveDependency(DefaultListableBeanFactory.java:855) at org.springframework.beans.factory.support.ConstructorResolver.resolveAutowiredArgument(ConstructorResolver.java:806) at org.springframework.beans.factory.support.ConstructorResolver.createArgumentArray(ConstructorResolver.java:734) ... 50 more 。

报错信息里 很明显：
No qualifying bean of type [javax.servlet.ServletContext] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {}
说的是 javax.servlet.ServletContext 找不到依赖， 首先看下自己引入Servlet-api 依赖没

<dependency> <groupId>javax.servlet</groupId> <artifactId>javax.servlet-api</artifactId> <version>3.1.0</version> <scope>provided</scope> </dependency>

然后 再看报错， Dependency annotations: {} 依赖注解，找不到注入javax.servlet.ServletContext 的实例，明显就是没有web容器环境 ，需要配置web容器配置

需要为测试类类添加注解 @WebAppConfiguration

这样就可以了，只是再遇到问题时候的一个小错误，SpringMVC 项目的单元测试都应该需要这个注解，才能初始化Web容器信息

谨记谨记，欢迎拍砖！
