⭐ 构建项目

配置build

构建jar或war

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <packaging>(jar|war)</packaging>
</project>

                </configuration>
            </plugin>
        </plugins>
    </build>
</project>

编译时去掉Tomcat

修改pom.xml


<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
    <version>${project.parent.version}</version>
    <scope>provided</scope>
</dependency>

修改启动文件

package com.lackoxygen.spring;

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

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
        return builder.sources(Application.class);
    }
}

打包

mvn clean package

stat target/*.jar

运行

java -jar target/*.jar

多个war部署到一个tomcat,可能会报错，springboot默认资源管理器是打开的，多个项目同时使用会冲突

spring:
  jvm:
    default-domain: api #每个工程设置不一样，就可以启动多个
