Mockito with Spring mvc

Question

下面是我使用 mockito 对控制器类进行单元测试的代码。

但是我收到如下运行时错误

java.lang.NoClassDefFoundError： org/springframework/web/servlet/FlashMapManager at org.springframework.test.web.servlet.setup.MockMvcBuilders.standaloneSetup（MockMvcBuilders.java：71）

任何人都可以帮我解决这个问题吗

您需要

静态导入get：

import static org.springframework.test.web.servlet.request.MockMvcRequestBuilders.get;

您还在使用status和view。您还需要导入它们：

import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.status;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.view;

编辑

：要在编辑中回答新问题，请确保您的类路径中有最新的 servlet API。如果您使用的是 Maven，请添加以下内容：

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