【问题描述】：
我有一个简单的 Spring Boot webmvc 应用程序，其 JSP 页面在本地工作，但是当我部署到 Pivotal Web 服务（由 Pivotal.io 托管）上时，查看 JSP 页面时出现错误。该应用程序被打包为 WAR：
2015-02-11 12:22:30.381 ERROR 31 --- [io-61338-exec-4] o.s.boot.context.web.ErrorPageFilter : Cannot forward to error page for request [/] as the response has already been committed. As a result, the response may have the wrong status code. If your application is running on WebSphere Application Server you may be able to resolve this problem by setting com.ibm.ws.webcontainer.invokeFlushAfterService to false
仔细查看远程系统上的文件，我的 JSP 文件似乎没有被部署。他们被删除。在我部署之前，它们就在 WAR 中。
我尝试过从 STS 3.6.3 SR1 和使用 CF 的命令行进行部署。
当我创建一个常规 Spring MVC 项目（不使用 Spring Boot）时，一切似乎都可以在本地和关键的 Web 服务云上运行。
我做错了什么？有没有我错过的配置设置？请帮忙。谢谢。
这是我的 Spring Boot 项目设置：
HomeController.java 的代码：
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
@Controller
public class HomeController {
@RequestMapping("/")
public String viewHomePage() {
return "home";
}
}
主类：
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class SpringBootHWorldApplication {
public static void main(String[] args) {
SpringApplication.run(SpringBootHWorldApplication.class, args);
}
}
ServletInitializer：
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.context.web.SpringBootServletInitializer;
public class ServletInitializer extends SpringBootServletInitializer {
@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(SpringBootHWorldApplication.class);
}
}
Application.Properties 文件：
spring.view.prefix: /WEB-INF/views/
spring.view.suffix: .jsp
我的jsp页面位于src/main/webapp/WEB-INF/views

远程系统上的文件。请注意文件夹 /WEB-INF/views 丢失。我尝试将文件移动到不同的位置，但每次文件都丢失，即使它在本地工作。

【问题讨论】：
-
根据这篇帖子：webserver.docs.pivotal.io/doc/60/web-server/src/config.html，然后将com.ibm.ws.webcontainer.invokeFlushAfterService设置为false
-
我在由pivotal 托管的云中使用PWS。我不认为我可以进入机器并进行任何更改。任何更改都必须在我的 Spring Boot 应用程序中。我需要在那里做什么？
-
如果你要部署到CF，我建议使用jar包而不是war。它更容易在本地运行，并且不太可能出现奇怪的组装问题。
