无法在Tomcat上访问已部署的WAR文件

Question

我有一个在我的本地机器上运行的Spring Boot Rest服务项目。当我运行该应用程序为“春启动应用程序”

我可以去访问其他服务

http://127.0.0.1:8080/persons/all

和它应该返回JSON。

我将pom.xml打包改成了war，然后我在Spring工具套装中以Run as - > Maven构建了一场战争。它创建一个战争文件。当我上传战争档案http://myserverip:8080/manager/我没有得到任何错误，它显示在应用程序

上传它后，战争文件名称是“myapp-0.0.1-SNAPSHOT.war”，我试图访问它

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

但我得到一个404错误

我在做什么错在这里？

我的pom.xml

当我构建应用程序，我得到以下日志

我MyappApplication.java

package com.mycompany; 

import org.springframework.boot.SpringApplication; 
import org.springframework.boot.autoconfigure.EnableAutoConfiguration; 
import org.springframework.context.annotation.ComponentScan; 
import org.springframework.context.annotation.Configuration; 

@Configuration 
@EnableAutoConfiguration 
@ComponentScan 
public class MyappApplication { 
    public static void main(String[] args) { 
     SpringApplication.run(MyappApplication.class, args); 
    } 
} 

Answer 1

延长SpringBootServletInitializer参见：Packaging executable jar and war files

正如评论中所提到的，传统上可以通过将war部署到独立的tomcat实例来部署spring引导应用程序。您需要对MyappApplication.java课程进行一些更改，该课程有main()方法。

• 让您MyappApplication延长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); 
      } 
  
  } 
  

• 下一个步骤是有包装的战争，而不是你已经有默认的罐子。

• 最后在您的pom.xml中将嵌入式tomcat容器的作用域更改为provided，以便在部署到单独的实例时不会发生冲突。

Answer 2

如果要更改罐子春季开机大战增加以下依赖关系

<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>

Answer 3

清单改变弹簧启动可执行的JAR文件到一个可部署的战争。

1. 更改包装的pom.xml到 “战争”，从 “罐子”

2. 正如kuhajeyan提到，标志着嵌入式tomcat的依赖性，在pom.xml提供。

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

3. 让你的主弹簧引导应用类这样

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