SpringBoot系列之jar包转war包

1.修改pom,将打包方式改为war包

2.dependencides中配置外部tomcat

 　　　　<!--因配置外部TOMCAT 而配置-->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-tomcat</artifactId>
            <scope>provided</scope>
        </dependency>

3.添加一个SpringBootServletInitializer 的继承类

package com.vrv.app;

import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.support.SpringBootServletInitializer;

/**
 * @Author：LJ
 * @Description：
 * @Date: 2018/5/18
 * @Modified By:
 */
public class DemoInitializer extends SpringBootServletInitializer {
    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
        return builder.sources(HuaxiaApplication.class);
    }
}

4.main主类还是保持不变

package com.vrv.app;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class DemoApplication {

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