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
<?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"> <modelVersion>4.0.0</modelVersion> <packaging>jar</packaging> <groupid>magic</groupId> <artifactid>magic</artifactId> <version>1.0-SNAPSHOT</version> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>1.4.3.RELEASE</version> </parent> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-jdbc</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> </dependency> <dependency> <groupId>com.alibaba</groupId> <artifactId>druid</artifactId> <version>1.0.10</version> </dependency> <dependency> <groupId>org.mybatis.spring.boot</groupId> <artifactId>mybatis-spring-boot-starter</artifactId> <version>1.1.1</version> </dependency> <dependency> <groupId>tk.mybatis</groupId> <artifactId>mapper-spring-boot-starter</artifactId> <version>1.0.0</version> </dependency> <dependency> <groupId>com.github.pagehelper</groupId> <artifactId>pagehelper-spring-boot-starter</artifactId> <version>1.0.0</version> </dependency> </dependencies> <build> <finalName>helloworld</finalName> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> </plugin> </plugins> </build> <repositories> <repository> <id>spring-milestone</id> <url>http://repo.spring.io/libs-release</url> </repository> </repositories> </project>
这里要注意的是，打包方式jar,不再是war
<packaging>jar</packaging>
自定义打包名称
<build> <finalName>helloworld</finalName> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> </plugin> </plugins> </build> <repositories> <repository> <id>spring-milestone</id> <url>http://repo.spring.io/libs-release</url> </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。
