【问题描述】：
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 迁移到嵌入的 tomcat。
现在，我的配置是这样的：
Application.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 和侦听器都从 web.xml 迁移到 @WebFilter、@WebListener 和 @WebServlets。
当我启动 tomcat 时，一切似乎都运行良好，并且我能够获得一些静态资源，如 html、css 和 js。
当我调用像http://localhost:8080/myapplication/login.go 这样的struts 页面时，一切正常，过滤器和servlet 被调用，我的动作被调用，但是当动作返回“成功”时调用“/myapplication/jsp/login.jsp”它没有渲染。没有调用 jsp 文件或有一些错误，我在控制台中什么也没有。
我的action调用jsp页面之前的日志：
