IntelliJ IDEA下spring boot项目打包

Spring Boot自带Tomcat插件，可以直接编写启动类，开启Tomcat服务

springboot适合前后端分离，打成jar进行部署更合适

application.properties配置端口

server.port=8089

marven的配置文件pom.xml

注：

　　如果打jar的时候会说找不到主类，build那部分修改下

    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
                <configuration>
                    <mainClass>com.company.project.Application</mainClass>
                </configuration>
            </plugin>
        </plugins>
    </build>

启动类修改下

package com.company.project;

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

@SpringBootApplication
public class Application {
    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
    //为了打包springboot项目
    protected SpringApplicationBuilder configure(
            SpringApplicationBuilder builder) {
        return builder.sources(this.getClass());
    }
}

按照顺序运行mvn clean再mvn install

我们需要的jar就打好包了

到这个目录下执行命令

java -jar project-1.0.jar
