无法访问 Tomcat 上部署的 WAR 文件

Question

我有一个 Spring 启动休息服务项目，可以在我的本地机器上运行。当我运行申请时"Spring Boot App"

我可以通过

访问其余服务

http://127.0.0.1:8080/persons/all

并且它 returns JSON 正如它应该的那样。

我将 pom.xml 包装更改为 war，然后我通过转到运行创建了一个 war as -> Maven build in Spring tools套装。它创建一个 war 文件。当我在 http://myserverip:8080/manager/ 上上传 war 文件时，我没有收到任何错误，它显示在应用程序

下

上传后war文件名为"myapp-0.0.1-SNAPSHOT.war"，我尝试通过

访问它

http://myserverip:8080/myapp-0.0.1-SNAPSHOT/persons/all

但是我收到 404 错误

我做错了什么？

Answer 1

如果您要将 jar 更改为 spring 引导的 war 添加以下依赖项

 <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>

http://docs.spring.io/spring-boot/docs/current/reference/htmlsingle/#build-tool-plugins-maven-packaging

Answer 2

将 spring 启动可执行 jar 更改为可部署 war 的检查清单。

将 pom.xml 中的包装从 "jar"

如 kuhajeyan 所述，标记 tomcat 中提供的嵌入式依赖项 pom.xml。

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

让你的主要 spring 引导应用程序 class 像这样扩展 SpringBootServletInitializer

@SpringBootApplication
public class Application extends SpringBootServletInitializer {
@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(Application.class);
 }
}

From the documentations

Answer 3

参考：Packaging executable jar and war files

如评论中所述，您可以通过将 war 部署到独立的 tomcat 实例来传统地部署 spring 启动应用程序。您需要对具有 main() 方法的 MyappApplication.java class 进行一些更改。

使您的 MyappApplication 扩展 SpringBootServletInitializer 并覆盖其 configure() 方法，

@SpringBootApplication
public class MyappApplication extends SpringBootServletInitializer {

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

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

}

下一步是将包装为 war 而不是您已有的默认 jar。
最后在您的 pom.xml 中将嵌入式 tomcat 容器的范围更改为 provided，这样当您部署到单独的实例时它就不会发生冲突。
