Spring boot jar包方式打包发布

很多大佬都已经写过了关于Spring boot 打包发布的博客,之前做项目的时候使用spring boot进行开发，碰到很多问题这里就写一个让自己回顾一下。

我这里是用idea 创建的spring boot项目

创建spring boot项目选择这个后Next就可以了

下一步后这个位置可以选择你用的爽的项目管理，我这里用的是maven，直接下一步。

做的一个预备项目，先实现功能，这里就只用了这几个依赖。这样一个spring boot的项目就搭好了。

进入后整个界面就是这样的，进来后先先写一个小Demo运行一下，运行成功就证码项目搭建好了，之后再配置application.yml文件，本来是.properties,为了看起来好看一些，这里就改成了.yml文件，已经配置

server:            
  port: 9090
  tomcat:
    accesslog:
      request-attributes-enabled: true
spring:
  datasource:
    data-username: flowmarket
    url: jdbc:mysql://localhost:3306/flowmarket?useUnicode=true&characterEncoding=utf8&autoReconnect=true&failOverReadOnly=false
    username: miaoyue
    password: mysqlmiaoyue
    driver-class-name: com.mysql.jdbc.Driver
#静态文件配置 这东西是在做图片上传到本地服务器后无法通过url访问配置的一个地址映射
  mvc:
    static-path-pattern: /**
  resources:
    static-locations: classpath:/META-INF/resources/,classpath:/resources/,\
                                              classpath:/static/,classpath:/public/,file:${web.upload-path}
web.upload-path: /var/apps/userimg/
#分页工具配置  高端大气上档次的工具 好吧主要是我用起来爽
pagehelper:
  helper-dialect: mysql
  support-methods-arguments: true
  params: countSql
  reasonable: false
#mybatis 映射配置
mybatis:
  mapper-locations: classpath:mapper/*.xml

接下来POM文件配置

在POM文件配置好之后 就可以做下面 打包发布

跳过测试单元打包，我这是因为打包时，测试类总是报错。逼不得已只能跳过。

打包完成后会在项目中生成一个项目名.jar的包这时候就可以用  java -jar 项目名.jar 来运行jar包

这样运行在服务器就不能进行其它操作，这时候我们需要在后台运行     

java -jar 项目名.jar &     这个命令就可以在后台运行

这样运行在服务器后台，有时候会挂断，所以直接使用下面这个命令就可以

nohup java -jar shareniu.jar &  

在其它环境下可能会遇到各种问题，不一定通用。写的不好还请见谅，有问题一起讨论讨论哈。
