將Spring Boot部署到Tomcat

Question

所以我是Spring的新手 - 所以我想我會嘗試Spring Boot

我正在使用Maven構建 - 我設置了一個視圖請求，當我運行它時，“App”看起來它啟動了tomcat本身並且我有一個默認8080端口的服務，所以當我調用localhost:8080/service it's都好。

但是，當我嘗試將其打包為WAR以部署到服務器時，它不起作用

所以我想我會回到基礎並將其部署到我的tomcat服務器本地，看看會發生什么

所以首先沒有任何事情發生 - 404 - 做了一些谷歌搜索發現我需要包括這樣的網絡入口點 - 這是我的主要課程

@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;
}

所以它看起來像是有效的，在控制台我可以看到紅色catalina啟動文本，然后我看到Spring啟動啟動（我之前沒有看到）

然而，當我嘗試調用服務localhost:8080/service我仍然得到404

當我將它作為“App”運行時，它會起作用

我需要做些什么嗎？ 我只是創造戰爭

1. 將pom xml包類型更改為war
2. 包含上面代碼段中的覆蓋
3. 作為戰爭出口

我解壓了WAR並且它看起來很好 - 有一個WEB-INF和一組依賴項等。

任何幫助都會很好 - 因為在將Spring引導應用程序部署為WAR時，任何人都有類似的問題嗎？

*** UPDATE ****

現在我可以讓我的戰爭在我的本地Tomcat 7服務器上正確部署 - 但是當我嘗試部署到外部托管的Tomcat容器時，我得到了

Answer 1

Spring Boot參考文檔中的Packaging executable jar和war文件一章說明：

要構建可執行且可部署到外部容器的war文件，您需要將嵌入式容器依賴項標記為“已提供”，例如：

<?xml version="1.0" encoding="UTF-8"?>
    <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <!-- ... -->
    <packaging>war</packaging>
    <!-- ... -->
    <dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-tomcat</artifactId>
            <scope>provided</scope>
        </dependency>
        <!-- ... -->
    </dependencies>
</project>

Answer 2

下面的代碼適用於沒有tomcat依賴的tomcat8部署。

@SpringBootApplication
@EnableAutoConfiguration
@ComponentScan
public class ManufacturingRegionApplication extends SpringBootServletInitializer {

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

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

private static Class<ManufacturingRegionApplication> application = ManufacturingRegionApplication.class;

}

以下依賴性不是必需的。

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

---

 @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")

Answer 3

當我們選擇Spring Boot時，我們不想生成WAR。 從根頁面 ：

Spring Boot makes it easy to create stand-alone [...] 
Applications that can you can "just run".
Embed Tomcat or Jetty directly (no need to deploy WAR files)

編輯：所以，如果目的是“嘗試Spring Boot”，我建議不要生成WAR文件。

如果你真的需要生成一個WAR文件（保持你的代碼針對SpringBoot構建並生成一個可以在任何標准servlet容器中運行的文件......）那么你應該閱讀文檔將Spring Boot JAR應用程序轉換為WAR 。

你是否在構建過程中包含了spring-boot-maven-plugin？ 你沒有描述這一步......
