SpringBoot应用程序Tomcat部署

Question

public class SkyVetApplication extends SpringBootServletInitializer{
...
   @Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
    return application.sources(SkyVetApplication.class);
}
...
}

compile group: 'org.springframework.boot', name: 'spring-boot-starter-web'
**providedRuntime 'org.springframework.boot:spring-boot-starter-tomcat'**

完成干净的构建后，我将war文件复制到Tomcat的webapps文件夹中。但是部署会发生两次，并且在上下文已经存在的情况下以异常结束。我错过了什么？

非常感谢您的帮助。

您应该添加一个main方法。

查看以下示例：https://github.com/pytry/bootiful-war-deployment

下面是“Hello”模块的一个示例（它使用Lombok注释处理器）。

package com.example.bootifulwar;

import lombok.extern.slf4j.Slf4j;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.support.SpringBootServletInitializer;
import org.springframework.scheduling.annotation.EnableScheduling;
import org.springframework.scheduling.annotation.Scheduled;

@SpringBootApplication
@EnableScheduling
@Slf4j
public class HelloServletInitializer extends SpringBootServletInitializer{

    @Value("${messageForUser}")
    private String message;

    @Value("${whatDoesTheFoxSay:'No body knows.'}")
    private String whatDoesTheFoxSay;

    public static void main(String[] args){

        SpringApplication.run(HelloServletInitializer.class, args);
    }

    @Scheduled(fixedRate = 2000)
    public void sayHelloTo(){

        log.info("Hello! " + message);
    }

    @Override
    public SpringApplicationBuilder configure(SpringApplicationBuilder application){

        log.info(
            "\n*********************\n" +
                "What does the fox say?\n" +
                whatDoesTheFoxSay +
                "\n*********************\n");
        return application.sources(HelloServletInitializer.class);
    }
}

<?xml version='1.0' encoding='utf-8'?>
<Context docBase="hello.war" path="hello">
  <Resources className="org.apache.catalina.webresources.StandardRoot">
    <PreResources base="hello\\config"
                  className="org.apache.catalina.webresources.DirResourceSet"
                  internalPath="/"
                  webAppMount="/WEB-INF/classes"/>
  </Resources>
</Context>
