SpringBoot项目的云服务器部署

1.场景还原

     springboot配置相当简单，人人皆知。怎么把springboot工程部署到云服务器上呢？可能有人会说，博主你前篇不是讲了java工程的云部署把；但是我想澄清一点的是，我前篇的工程都是ssm框架搭建的，而springboot可是自带tomcat喽！这就有点麻烦....淡定，往下看

2.配置解析

①application.properties文件

# EMBEDDED SERVER CONFIGURATION (ServerProperties)
server.port=8010
server.session-timeout=1800
server.context-path=
server.tomcat.max-threads=0
server.tomcat.uri-encoding=UTF-8
server.tomcat.basedir=target/tomcat

# HTTP encoding (HttpEncodingProperties)
spring.http.encoding.charset=UTF-8
spring.http.encoding.enabled=true 
spring.http.encoding.force=true

#datasource
spring.datasource.url=jdbc:mysql://192.168.0.129/ccoee?useUnicode=true&characterEncoding=UTF-8
spring.datasource.username=zhangxing
spring.datasource.password=zxp52077
spring.datasource.driverClassName=com.mysql.jdbc.Driver

#mybatis
mybatis.type-aliases-package=com.cckj.model
mybatis.mapper-locations=classpath:mapper/*.xml

#mapper
mapper.mappers=tk.mybatis.mapper.common.Mapper
mapper.not-empty=false
mapper.identity=MYSQL

#pagehelper
pagehelper.helperDialect=mysql
pagehelper.reasonable=true
pagehelper.supportMethodsArguments=true
pagehelper.params=count=countSql

#logging
#logging.level.root=INFO
#logging.level.org.springframework.web=DEBUG
logging.level.org.zhangxing=DEBUG

就是这个文件 包罗了ssm框架的烦琐配置，哪个程序员不爱呢？那么既然爱，请深爱！将远程数据库连接配好，这里不再赘述。

②pom.xml

<packaging>jar</packaging>

自定义打包名称

        <groupId>org.springframework.boot</groupId>

      <id>spring-milestone</id>

    </repository>
  </repositories>

③Application启动类代码

@SpringBootApplication
@MapperScan(basePackages = "com.cckj.dao", markerInterface =Mapper.class)
public class Application {


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

注意：各个方法中的测试主函数最好全部注释掉！

3.实现方案

准备工作：在部署之前，首先确认云服务器是否装有tomcat环境，并且服务时候开启！若无环境，请自行安装并开启服务

①开始打jar包

跟前篇步骤一样，点开右边的Maven Project，点击Lifecycle,最后双击packet,生成jar包

②将刚打的jar上传至云服务器的java目录下

③运行命令：java -jar helloworld.jar,然后springboot工程的内置tomcat就开启了

注意：部署好之后，需要开放端口号：3306，8089

访问效果：

这里还没完呢，当然你关闭当前的xshell 命令界面时，再次访问就失效了，这是因为springboot内置的tomcat随之也关闭了，那么有人会问，这叫什么云部署呀？跟本地没两样，是啊，我也这么觉得；别急，往下看

④常驻云服务器

运行命令： nohup java -jar helloworld.jar &

nohup的意思不挂服务，常驻的意思，除非云服务器重启，那就没法了；最后一个&表示执行命令后要生成日志文件nohup.out

好了，这样就不担心关闭xshell,只要云服务器不关闭，总能访问的。
