SpringBoot 2.x 以War包外置Tomcat启动的标准做法-来自Spring官方指南

Posted 2021-09-04 xiaoyanbot

第一步：

pom文件排除内置Tomcat依赖

       <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-tomcat</artifactId>
            <scope>provided</scope>
        </dependency>

jar包打包方式改为war包

第二步：

在xxxApplication.java同目录下，新增 ServletInitializer.java

package com.example.demo;

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

public class ServletInitializer extends SpringBootServletInitializer {

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

}

完毕。
