Question

遇到错误java.lang.NoSuchMethodError: javax.servlet.http.HttpServletResponse.getStatus()

在pom.xml中，我提到了2个依赖项

<!--For DispatcherServlet-->
<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>servlet-api</artifactId>
    <version>2.5</version>
</dependency>

<!--For Spring JUnit + mockito test-->
<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>javax.servlet-api</artifactId>
    <version>3.0.1</version>
    <scope>provided</scope>
</dependency>
<dependency>
    <groupId>org.mockito</groupId>
    <artifactId>mockito-core</artifactId>
    <version>2.21.0</version>
</dependency>

“我的测试”课程中的代码

this.mockMvc = MockMvcBuilders.webAppContextSetup(wac).build();
mockMvc.perform(MockMvcRequestBuilders.post("/user/login").accept(MediaType.APPLICATION_JSON))
        .andExpect(status().isOk()).andDo(print());

Answer 1

您使用不同版本的javax.servlet进行测试。 getStatus()方法仅在Servlet 3.0版中添加，您在pom的JUnit测试部分指定了2.5版。

Answer 2

我认为您需要使用Servlet 3.1容器作为最低要求，但是看起来您使用的是嘲笑2.21，它最多使用Servlet 2.5容器。我认为这行不通。

java.lang.NoSuchMethodError：javax.servlet.http.HttpServletResponse.getStatus（）
