Java 将 Spring Boot 部署到 Tomcat

Question

提问by philthomas26

So I am new to Spring - so I thought I would try Spring Boot

所以我是 Spring 的新手 - 所以我想我会尝试 Spring Boot

I am using a Maven to build - I set up a view requests, when I run it as "App" looks like it starts tomcat up itself and i have a service at default 8080 port, so when I call localhost:8080/serviceit's all good.

我正在使用 Maven 来构建 - 我设置了一个视图请求，当我将它作为“应用程序”运行时，它看起来像它自己启动 tomcat 并且我在默认的 8080 端口有一个服务，所以当我调用localhost:8080/service它时一切都很好。

However when i try to package it up as a WAR to deploy to a server it doesn't work

但是，当我尝试将其打包为 WAR 以部署到服务器时，它不起作用

So i thought i would go back to basics and deploy it onto my tomcat server locally and see what happens

所以我想我会回到基础并将它部署到我本地的 tomcat 服务器上，看看会发生什么

So first off nothing happened - 404 - did a bit of googling at found out i need to include a web entry point like this - here's my main class

所以首先什么也没发生 - 404 - 做了一些谷歌搜索，发现我需要包含一个这样的网络入口点 - 这是我的主要课程

@ComponentScan
@EnableAutoConfiguration
public class App extends SpringBootServletInitializer
{

    public static void main( String[] args )    {
        SpringApplication.run(App.class, args);
    }

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(appClass);
    }

    private static Class<App> appClass = App.class;
}

so it looked like it worked, in the console i could see the red catalina startup text, then i saw the Spring boot start up (which i wasn't seeing before)

所以看起来它起作用了，在控制台中我可以看到红色的 catalina 启动文本，然后我看到了 Spring boot 启动（我以前没有看到过）

however when i try and call the service localhost:8080/servicei still get a 404

但是，当我尝试致电该服务时，localhost:8080/service我仍然收到 404

when i run it as "App" it works a treat

当我将它作为“应用程序”运行时，它会很好用

is there something obvious i need to be doing ? to create the war i just

有什么明显的我需要做的吗？制造War，我只是

changed the pom xml package type to war
included the override in the code snippet above
exported as a war

将 pom xml 包类型更改为 war
在上面的代码片段中包含覆盖
作为War出口

i have unzipped the WAR and it looked fine - there is a WEB-INF and a set of dependencies, etc.

我已经解压缩了 WAR，它看起来很好 - 有一个 WEB-INF 和一组依赖项等。

any help would be good - as anyone had similar problems when deploying spring boot apps as a WAR?

任何帮助都会很好 - 因为在将 Spring Boot 应用程序部署为 WAR 时有人遇到过类似的问题吗？

***UPDATE****

***更新****

Now i can get my war to deploy correctly on my local Tomcat 7 server - but when i try and deploy to an externally hosted Tomcat container i get

现在我可以让我的War在我的本地 Tomcat 7 服务器上正确部署 - 但是当我尝试部署到外部托管的 Tomcat 容器时，我得到

The chapter Packaging executable jar and war filesin the Spring Boot reference documentation states:

Spring Boot 参考文档中的Packaging executable jar and war files一章指出：

To build a war file that is both executable and deployable into an external container you need to mark the embedded container dependencies as “provided”, e.g:

要构建一个既可执行又可部署到外部容器中的 war 文件，您需要将嵌入式容器依赖项标记为“已提供”，例如：

   <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-tomcat</artifactId>
        <scope>provided</scope>
    </dependency>

When we choose Spring Boot, we don't want to produce a WAR. From the root page:

当我们选择 Spring Boot 时，我们不想产生 WAR。从根页面：

 @RestController
 @RequestMapping(value = "/manufacturing-region-service")
 public class ManufacturingRegionService {

@Resource
private ManufacturingRegionDao manufacturingRegionDao;

@ResponseBody
@Transactional(readOnly = true)
@RequestMapping(value = "/region-codes/{abbr}", method = GET, produces = "application/json")

EDITED: So, if the purpose is "to try Spring Boot", I suggest to not generate a WAR file.

编辑：因此，如果目的是“尝试 Spring Boot”，我建议不要生成 WAR 文件。

If you really need to produce a WAR file (keep your code built against SpringBoot and produce a file that you can run in any standard servlet container...) then you should read the documentation Converting a Spring Boot JAR Application to a WAR.

如果您确实需要生成一个 WAR 文件（保持您的代码针对 SpringBoot 构建并生成一个可以在任何标准 servlet 容器中运行的文件...），那么您应该阅读文档将 Spring Boot JAR 应用程序转换为 WAR。

Did you include spring-boot-maven-plugin in the build process? You didn't describe this step...

您是否在构建过程中包含 spring-boot-maven-plugin ？你没有描述这一步...
