在Eclipse中，“ mvn spring-boot：run”和“添加到Tomcat服務器”之間有什么區別？

Question

我從此處下載了Spring-boot CXF Web服務樣本。 我能夠使用以下命令在Eclipse中成功運行它： 右鍵單擊項目>運行方式> Maven build ...>並設置目標： spring-boot：run

服務器啟動，所有內容都記錄到控制台中。

接下來，我嘗試將其部署在Eclipse中的Tomcat服務器上（請參見screenshot.png ），但是當服務器啟動時，Spring並沒有啟動。 沒有Spring信息登錄到控制台

根據日志中的一行，它知道彈簧應該啟動。 那為什么不能正常啟動呢？

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

Answer 1

從spring boot項目中生成的jar中將包含tomcat服務器。 您可以使用以下命令啟動服務器

java -jar XXX.jar

Answer 2

我找到了無法啟動的原因。 現在它為我工作。 為了在eclipse tomcat上運行，您需要將extends SpringBootServletInitializer添加到項目的主類App.java中。

所以結果看起來像

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);
    }

}
