啓動類

package com.ds.ksh.v1;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;

/*@SpringBootApplication

    public static void main(String[] args) {
        SpringApplication.run(KshApplication.class, args);
    }
}*/
@SpringBootApplication
public class KshApplication extends SpringBootServletInitializer {


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

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(KshApplication.class);
    }
}

　　tomcat部署   tomcat7使用以上版本否則有時候啓動肯有問題

刪除ROOT --> 將war複製到webapp下  -->  修改項目名字爲ROOT.war 

這樣的好處是不用再配置別的東西直接啓動就能訪問
