将 Spring Boot 部署到 Tomcat

java tomcat spring spring-boot war
2022-09-01 11:58:19

所以我是春天的新手 - 所以我想我会尝试春天的靴子

我正在使用Maven来构建 - 我设置了一个视图请求，当我以“App”运行它时，它看起来像是启动tomcat本身，并且我在默认的8080端口有一个服务，所以当我调用它时，一切都很好。localhost:8080/service

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

所以我想我会回到基础，把它部署到我的tomcat服务器本地，看看会发生什么

所以首先什么也没发生 - 404 - 做了一些谷歌搜索，发现我需要包括一个像这样的网络入口点 - 这是我的主要类

@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;
}

所以它看起来像工作，在控制台中我可以看到红色的catalina启动文本，然后我看到Spring启动（我以前没有看到）

但是当我尝试调用服务时，我仍然得到404localhost:8080/service

当我将其作为“应用程序”运行时，它的工作原理是一种享受

我需要做些什么明显的事情吗？创造战争我只是

  1. 将 pom xml 包类型更改为 war
  2. 在上面的代码片段中包含覆盖
  3. 作为战争出口

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。

任何帮助都会很好 - 因为任何人在将春季启动应用程序部署为WAR时都有类似的问题？

更新****

现在我可以让我的战争正确地部署在我的本地Tomcat 7服务器上 - 但是当我尝试部署到外部托管的Tomcat容器时，我得到了

在 Spring Boot 参考文档中打包可执行 jar 和 war 文件一章中指出：

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“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>

答案 2

下面的代码对于没有tomcat依赖性的tomcat8部署工作得很好。

@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;

}

以下依赖项不是必需的。

   <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")

http://localhost:8080/manufacturing-region-api/manufacturing-region-service/region-codes/ABBRVALUE
