Spring Boot 如何让项目在 Eclipse 中的服务器上运行

Spring boot how to make project run on server in eclipse

提问by Kamini

I am new to Spring Boot, I have sample spring boot code in my Eclipse IDE.

Now to run the project. In project there is class "Application", I run that using Run As Java Application and then Its running on given port.

But I want it to run using Run on Server option of Eclipse, so whenever I try to run that on server it gives me 404.

我是 Spring Boot 的新手，我的 Eclipse IDE 中有示例 Spring Boot 代码。

现在运行项目。在项目中有类“应用程序”，我使用 Run As Java Application 运行它，然后它在给定的端口上运行。

但我希望它使用 Eclipse 的“在服务器上运行”选项运行，所以每当我尝试在服务器上运行它时，它都会给我 404。

Please give me any idea to resolve this issue.

请给我解决此问题的任何想法。

Code:

代码：

@ComponentScan
@Configuration
@EnableAutoConfiguration
public class Application extends SpringBootServletInitializer {

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

    public static void main(String[] args) {
        ApplicationContext ctx = SpringApplication.run(Application.class, args);

        System.out.println("Let's inspect the beans provided by Spring Boot:");
        String[] beanNames = ctx.getBeanDefinitionNames();
        Arrays.sort(beanNames);
        System.out.println(Arrays.toString(beanNames));
    }
}

application.properties

应用程序属性

server.address=localhost
server.port=8080
server.contextPath=/spring-security-cas
app.service.security=http://localhost:8080/j_spring_cas_security_check
app.service.home=http://localhost:8080/

Note: Project running when run Application as Run as Java Application, problem is I want it to run using Run on Server option.

注意：当将 Application 作为 Run as Java Application 运行时，项目正在运行，问题是我希望它使用 Run on Server 选项运行。

If you want to deploy it to a container, instead of using the embedded container follow this sectionin the reference guide.

如果要将其部署到容器中，而不是使用嵌入式容器，请按照参考指南中的这一部分进行操作。

In short the steps are

简而言之，步骤是

1. Use warpackaging instead of jarpackaging
2. Let your Applicationclass extends SpringBootServletInitializerand implement the configuremethod.
3. Mark the container dependencies (tomcat I guess) as provided

1. 使用war包装代替jar包装
2. 让您的Application类扩展SpringBootServletInitializer并实现该configure方法。
3. 将容器依赖项（我猜是 tomcat）标记为 provided

So in a nutshell

所以简而言之

1. Change <packaging>jar</packaging>to <packaging>war</packaging>

2. Change your Application

   public class Application extends SpringBootServletInitializer {
       ...
       protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
           return builder.sources(Application.class);
       }
   }
   

3. Add tomcat dependency as provided.

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

1. 更改<packaging>jar</packaging>为<packaging>war</packaging>

2. 改变你的 Application

   public class Application extends SpringBootServletInitializer {
       ...
       protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
           return builder.sources(Application.class);
       }
   }
   

3. 将 tomcat 依赖项添加为provided.

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

For more elaborate information check the reference guide.

有关更多详细信息，请查看参考指南。

Do you mean a tomcat instance on eclipse? What are the logs saying? That there is no application deployed?

你是说eclipse上的tomcat实例吗？日志在说什么？那有没有应用部署？

Then you need to deploy a war to tomcat -

然后你需要部署一个war到tomcat——

改变 -

 <packaging>jar</packaging>

To

<packaging>war</packaging>

And it should work.

它应该工作。
