Springboot项目打war包并且部署到Tomcat7-蒲公英云

Springboot框架自带了内置的Tomcat,通过查看依赖的jar包可以查看当前你项目版本对应的内置tomcat的版本号.

springboot版本较高的情况下,需要较高版本的jdk和tomcat才能运行起来,最近在整一个springboot项目,由于前后端没有分离,页面在工程里面.打成war包需要在tomcat7版本中,进行运行,刚刚开始的时候出现各种问题,后发现是版本兼容问题.

pom.xml如下:

需要将springboot的版本对应的降低,我使用的是1.5.4.

二: springboot 打war包时启动类

package com.techsun.system;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.support.SpringBootServletInitializer;
/**
 * springboot项目打war包时的启动类
 * @author 
 *
 */
@SpringBootApplication()
public class WarTechsunApplication extends SpringBootServletInitializer {
    public static void main(String[] args) {
        SpringApplication.run(WarTechsunApplication.class, args);
    }
    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
        return builder.sources(WarTechsunApplication.class);
    }
}
