使用 Spring 引导项目时,JSP 个文件未部署到 Pivotal Web 服务

JSP files not deployed to Pivotal Web Services when using Spring Boot project

我有一个简单的 Spring Boot webmvc 应用程序,其中有一个 JSP 页面在本地工作,但是当我部署到 Pivotal Web Services(由 Pivotal.io 托管)时,我收到一个错误查看 JSP 页面时。该应用程序打包为 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 文件似乎没有部署。他们被删除了。它们在我部署之前 WAR。

我已经尝试从 STS 3.6.3 SR1 和使用 CF 从命令行进行部署。

当我创建一个常规 Spring MVC 项目(不使用 Spring 引导)时,一切似乎都在本地和关键的 Web 服务云上工作。

我做错了什么?我错过了配置设置吗?请帮忙。谢谢。

这是我的 Spring 引导项目设置:

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";
    }
}

主要class:

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,但每次文件丢失,即使它在本地工作。

经过多次故障排除,我相信我已经解决了我的问题。为了让事情正常进行,我做了以下事情:

  1. 右键单击项目并选择属性。
  2. Select 项目方面。
  3. 取消选中动态 Web 模块并退出对话框。
  4. 返回项目方面
  5. 选中动态 Web 模块并选择 link "Further configuration available..."
  6. 在内容目录中输入路径 "src/main/webapp"。
  7. 退出对话框。

这做了两件事。

首先,这在我的 webapp 目录中添加了带有清单文件的 META-INF 文件夹。

其次,它更新了 .settings 文件夹中的文件 org.eclipse.wst.common.component。

在进行上述更改之前,存在以下行:

<wb-resource deploy-path="/" source-path="/target/m2e-wtp/web-resources"/>

org.eclipse.wst.common.component

的内容
<?xml version="1.0" encoding="UTF-8"?><project-modules id="moduleCoreId" project-version="1.5.0">
    <wb-module deploy-name="SpringBootHelloWorld-06">
        <wb-resource deploy-path="/WEB-INF/classes" source-path="/src/main/java"/>
        <wb-resource deploy-path="/WEB-INF/classes" source-path="/src/main/resources"/>
        <wb-resource deploy-path="/" source-path="/src/main/webapp" tag="defaultRootSource"/>
        <wb-resource deploy-path="/" source-path="/target/m2e-wtp/web-resources"/>
        <property name="context-root" value="demo"/>
        <property name="java-output-path" value="/SpringBootHelloWorld-06/target/classes"/>
    </wb-module>
</project-modules>

我也尝试过使用清单文件手动添加 META-INF 文件夹,但没有成功。所以我怀疑,这个文件的变化可能是原因,虽然我不确定。也许在这方面有更深入了解的人可以阐明一些问题。

我最初在这里的回答被某人删除了,所以 OP 和我正在互动 elsewhere. In summary, it is found that using STS for the deployment isn't working, and using the cf command line tool (say, as described here) 代替。想在这里报告它,以便它可能对偶然发现此问题的人有用post。
