SpringBoot編譯打包成war

springboot内置了Tomcat，要想不和服务器上的tomcat版本引起冲突，首先需要将springboot内置的tomcat依赖移除。

第一步：去除tomcat依赖并修改打包方式

将打包方式修改为war

<packaging>war</packaging>  
去除tomcat依赖

<dependency>  
   <groupId>org.springframework.boot</groupId>  
   <artifactId>spring-boot-starter-web</artifactId>  
     
   <exclusions>  
      <exclusion>  
         <groupId>org.springframework.boot</groupId>  
         <artifactId>spring-boot-starter-tomcat</artifactId>  
      </exclusion>  
   </exclusions>  
</dependency>  
或者  
<dependency>  
   <groupId>org.springframework.boot</groupId>  
   <artifactId>spring-boot-starter-tomcat</artifactId>  
   <scope>provided</scope>  
</dependency>  
将tomcat依赖作用域设置为provided

第二步：修改启动文件，继承SpringBootServletInitializer

import org.slf4j.Logger;
    import org.slf4j.LoggerFactory;
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    import org.springframework.boot.builder.SpringApplicationBuilder;
    import org.springframework.boot.web.servlet.ServletComponentScan;
    import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;
    
    import java.util.Calendar;
    import java.util.Date;
    
    @SpringBootApplication
    @ServletComponentScan
    public class TrainsApplication extends SpringBootServletInitializer {
    
        public static void main(String[] args) {
            Logger logger= LoggerFactory.getLogger(ResponseUtil.PROJECT_NAME);
            Date begin=Calendar.getInstance().getTime();
            logger.debug("项目开始启动,开始时间{}。", begin);
            SpringApplication.run(TrainsApplication.class, args);
            logger.debug("项目成功启动，耗时{}毫秒。",Calendar.getInstance().getTime().getTime()-begin.getTime());
        }
    
        protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
            // 注意这里要指向原先用main方法执行的Application启动类
            return builder.sources(TrainsApplication.class);
        }
    
    
    }
