無法在Tomcat上訪問已部署的WAR文件

Question

我有一個在我的本地機器上運行的Spring Boot Rest服務項目。當我運行該應用程序爲「春啓動應用程序」

我可以去訪問其他服務

http://127.0.0.1:8080/persons/all

和它應該返回JSON。

我將pom.xml打包改成了war，然後我在Spring工具套裝中以Run as - > Maven構建了一場戰爭。它創建一個戰爭文件。當我上傳戰爭檔案http://myserverip:8080/manager/我沒有得到任何錯誤，它顯示在應用程序

上傳它後，戰爭文件名稱是「myapp-0.0.1-SNAPSHOT.war」，我試圖訪問它

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

但我得到一個404錯誤

我在做什麼錯在這裏？

我的pom.xml

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

延長SpringBootServletInitializer參見：Packaging executable jar and war files

正如評論中所提到的，傳統上可以通過將war部署到獨立的tomcat實例來部署spring引導應用程序。您需要對MyappApplication.java課程進行一些更改，該課程有main()方法。

• 讓您MyappApplication延長SpringBootServletInitializer並覆蓋其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); 
      } 
  
  } 
  

• 下一個步驟是有包裝的戰爭，而不是你已經有默認的罐子。

• 最後在您的pom.xml中將嵌入式tomcat容器的作用域更改爲provided，以便在部署到單獨的實例時不會發生衝突。

Answer 2

如果要更改罐子春季開機大戰增加以下依賴關係

<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 3

清單改變彈簧啓動可執行的JAR文件到一個可部署的戰爭。

1. 更改包裝的pom.xml到 「戰爭」，從 「罐子」

2. 正如kuhajeyan提到，標誌着嵌入式tomcat的依賴性，在pom.xml提供。

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

3. 讓你的主彈簧引導應用類這樣

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