spring整合junit

spring整合junit时遇到的问题

1、Could not autowire field: private javax.servlet.http.HttpServletRequest

参考：https://www.cnblogs.com/summary-2017/p/8000626.html

https://stackoverflow.com/questions/17619029/spring-junit-test-case-failed

@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

2、添加@WebAppConfiguration注解后又有错误： java.util.MissingResourceException: Can't find bundle for base name javax.servlet.LocalStrings, locale zh_CN

报错原因：
Your running tests are missing the servlet-api dependency.
If you're using maven make sure this dependency is in your project:

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

 

也可以将tomcat运行jar添加到buildpath，这样本地测试的时候使用Server Runtime里面的servlet.jar；但是使用maven打包项目时仍然会报错，所以最好还是在maven中添加依赖。

 

3、java.lang.NoClassDefFoundError: com/jayway/jsonpath/InvalidPathException

　　缺少了jar包，可以添加以下的maven依赖：

<dependency>
    <groupId>com.jayway.jsonpath</groupId>
    <artifactId>json-path</artifactId>
    <version>0.8.1</version>
    <scope>test</scope>
</dependency>
<dependency>
    <groupId>com.jayway.jsonpath</groupId>
    <artifactId>json-path-assert</artifactId>
    <version>0.8.1</version>
    <scope>test</scope>
</dependency>
