Spring启动如何在eclipse中使项目在服务器上运行

Question

我是Spring Boot的新手，我在Eclipse IDE中有示例Spring启动代码。

现在运行该项目。 在项目中有类“Application”，我使用Run As Java Application运行它，然后在给定端口上运行它。

但我希望它使用Eclipse的Run on Server选项运行，因此每当我尝试在服务器上运行它时它就会给我404。

请给我任何解决此问题的想法。

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

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：项目运行时运行Application as Run as Java Application，问题是我希望它使用Run on Server选项运行。

Answer 1

如果要将其部署到容器，而不是使用嵌入式容器，请参阅参考指南中的此部分 。

简而言之，步骤是

1. 使用war包装而不是jar包装
2. 让您的Application类扩展SpringBootServletInitializer并实现configure方法。
3. 标记容器依赖（Tomcat的我猜的）作为provided

所以简而言之

1. 将<packaging>jar</packaging>更改为<packaging>war</packaging>

2. 更改您的Application

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

3. 放入tomcat依赖的provided 。

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

有关更详细的信息，请查看参考指南 。

Answer 2

你的意思是日食上的tomcat实例吗？ 日志说什么？ 没有部署应用程序？

然后你需要向tomcat部署战争 -

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

改变 -

 <packaging>jar</packaging>

至

<packaging>war</packaging>

它应该工作。
