在Eclipse中，“ mvn spring-boot：run”和“添加到Tomcat服务器”之间有什么区别？

Question

我从此处下载了Spring-boot CXF Web服务样本。 我能够使用以下命令在Eclipse中成功运行它： 右键单击项目>运行方式> Maven build ...>并设置目标： spring-boot：run

服务器启动，所有内容都记录到控制台中。

接下来，我尝试将其部署在Eclipse中的Tomcat服务器上（请参见screenshot.png ），但是当服务器启动时，Spring并没有启动。 没有Spring信息登录到控制台

根据日志中的一行，它知道弹簧应该启动。 那为什么不能正常启动呢？

INFO: Spring WebApplicationInitializers detected on classpath: [org.springframework.boot.autoconfigure.jersey.JerseyAutoConfiguration@4ed48c2]

Answer 1

从spring boot项目中生成的jar中将包含tomcat服务器。 您可以使用以下命令启动服务器

java -jar XXX.jar

Answer 2

我找到了无法启动的原因。 现在它为我工作。 为了在eclipse tomcat上运行，您需要将extends SpringBootServletInitializer添加到项目的主类App.java中。

所以结果看起来像

package com.foo.bar;

import some.imported.package
import another.imported.package

@SpringBootApplication
public class App extends SpringBootServletInitializer {

    public static void main(String[] args) {
        SpringApplication.run(App.class, args);
    }

}
