There are two things needing fixed -

有两件事需要修复——

• Rename spring-servlet.xml to Spring_Test-servlet.xml
• Add view resolver to the directory holding your view files -

• 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>

另外，您的 spring 配置 xml 中不需要 spring mvc 条目。就像是：

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

I too faced the same issue but my code included headers="Accept=application/json"at request mapping and it worked fine when I removed that tag.

我也遇到了同样的问题，但我的代码包含headers="Accept=application/json"在请求映射中，当我删除该标签时它运行良好。
