【问题描述】：

亲爱的， 我正在尝试使用 SpringBoot 迁移 Struts2 Web 应用程序。许多主题都在谈论未渲染和下载的 JSP，但我仍然找不到合适的解决方案。 看起来好像没有调用 ACTION 类，但是找到并下载了 JSP，而不是渲染。

我已经把我的jsp文件放在了

src/main/resources/META-INF/resources

也试过了

webapp 和 webapp/WEB-INF

我也尝试过添加一个 Struts2Configuration 类：

@Configuration
public class Struts2Configuration 
    @Bean
    public ServletRegistrationBean servletRegistrationBean(final DispatcherServlet dispatcherServlet) 
        final ServletRegistrationBean servletRegistrationBean = new ServletRegistrationBean(dispatcherServlet);
        servletRegistrationBean.setEnabled(false);

        return servletRegistrationBean;
    
    @Bean
    public FilterRegistrationBean someFilterRegistration() 
        FilterRegistrationBean registration = new FilterRegistrationBean();
        registration.setFilter(new StrutsPrepareAndExecuteFilter());
        registration.addUrlPatterns("*.action");
        registration.setDispatcherTypes(DispatcherType.REQUEST, DispatcherType.FORWARD);
        registration.setName("StrutsPrepareAndExecuteFilter");
        return registration;

【问题讨论】：

你把jsp放到webapp/WEB-INF的时候，你在application.properties中配置了吗？

【参考方案1】：

没有错。 spring.mvc.view.prefix - 是 Str

【讨论】：

请阅读***.com/help/how-to-answer，了解如何写出好的答案。正如目前所写的那样，您的答案对其他人几乎没有用处。

【参考方案2】：

你应该添加 application.properties

spring.mvc.view.prefix:/WEB-INF/views/
spring.mvc.view.suffix:.jsp

或application.yml

spring:
 mvc:
  view:
   prefix: /WEB-INF/views/
   suffix: .jsp

【讨论】：

谢谢你的回答，我试试。但似乎当我键入 localhost/home.action 时，它并没有通过我的 Struts Action 类（由 struts.xml 引导）。它不会解决问题，对吧？
