Error: HTTP Status 500 - Servlet.init() for servlet Spring_Test threw exception?

Question

我正在尝试一个简单的 Spring-MVC 应用程序，它接受用户的输入并将其显示在屏幕上。我收到以下错误消息：

异常：

javax.servlet.ServletException: Servlet.init() for servlet Spring_Test threw exception

你能帮我解决这个问题吗？

Answer 1

看起来您的控制器上有注释或未正确加载。

此外，您的 spring 配置 xml 中不需要 spring mvc 条目。类似于：

<beans:beans xmlns="http://www.springframework.org/schema/mvc

Answer 2

有两件事需要修复 -

将 spring-servlet.xml 重命名为 Spring_Test-servlet.xml
将视图解析器添加到保存视图文件的目录中 -

<bean id="viewResolver"
 class="org.springframework.web.servlet.view.UrlBasedViewResolver"> 
 <property name="viewClass"
 value="org.springframework.web.servlet.view.JstlView" />  <property
 name="prefix" value="/WEB-INF/views/" />  <property name="suffix"
 value=".jsp" />  </bean>

我也面临同样的问题，但我的代码在请求映射中包含 headers="Accept=application/json"，当我删除该标签时它工作正常。
