如何在eclipse中让项目在服务器上运行

Question

我是Spring Boot的新手，我的EclipseIDE中有Spring启动代码示例。

现在来运行这个项目。在项目中有一个“应用程序”类，我使用作为Java应用程序运行，然后它在给定的端口上运行。

但我希望它使用Eclipse的RunonServer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。

请给我任何想法来解决这个问题。

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));
    }
}

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/

注意：当以Java应用程序的形式运行应用程序时，项目正在运行，问题是我希望它使用服务器上运行选项运行。

Answer 1

你是说eclipse上的tomcat实例吗？日志在说什么？没有部署应用程序？

那么你需要对tomcat发动一场战争-

http://docs.spring.io/spring-boot/docs/current/reference/htmlsingle/#howto-create-a-deployable-war-file

改变-

 <packaging>jar</packaging>

到

<packaging>war</packaging>

它应该有效。

Answer 2

如果要将其部署到容器中，而不是使用嵌入式容器，请遵循《参考指南》中的这一节。

简言之，步骤如下：

1. 使用战争包装代替罐装包装
2. 让你的应用程序类扩展 SpringBootServletInitializer 并实现 configure 方法。
3. 将容器依赖项（我猜是 tomcat）标记为提供

所以简单来说

>

更改<代码>

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

将tomcat依赖项添加为提供的。

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

有关详细信息，请参阅参考指南。
