spring-boot - Spring Boot + Tomcat Embedded + Struts 2 - 不调用 JSP

Question

我正在尝试将带有 spring boot 和 struts 2(struts.xml 文件)的 Web 应用程序从 Jboss 7.1.1 迁移到嵌入式 tomcat。

现在，我的配置是这样的:

应用程序.java

@SpringBootApplication()
@ServletComponentScan()
public class Application extends JbossDefaultPropertiesInitializer {

    public static void main(String[] args) {
        configureApplication(new SpringApplicationBuilder()).run(args);
    }

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
        setRegisterErrorPageFilter(false);
        return configureApplication(builder);
    }

    private static SpringApplicationBuilder configureApplication(SpringApplicationBuilder builder) {
        builder.initializers(new DefaultPropertiesInitializer());
        return builder.sources(Application.class);
    }
}

pom.xml

struts.devMode=true

每个过滤器、servlet 和监听器都从 web.xml 迁移到@WebFilter、@WebListener 和@WebServlets。

当我启动 tomcat 时，一切似乎都工作正常，并且我能够获得一些静态资源，如 html、css 和 js。

当我调用一些像 http://localhost:8080/myapplication/login.go 这样的 struts 页面时，一切都很好，调用了过滤器和 servlet，调用了我的操作，但是当操作返回“成功”以调用“/myapplication/jsp/login.jsp”时，它没有呈现。未调用 jsp 文件或存在一些错误，我在控制台中什么也没有得到。

我的操作调用jsp页面之前的日志:

拜托，有什么想法吗？

您是否尝试过将 jsp 文件从 src/main/webapp 文件夹简单地移动到 src/main/resources/META-INF/resources/WEB-INF ？ Servlet 3.0 规范允许在 src/main/resources/META-INF/resources/中有动态页面
