spring boot 定时备份数据库

Posted 2021-01-13 lick

第一步 ：添加mysqldump.exe 进环境变量

第二步  新建一个spring boot 项目,连接数据库

spring.datasource.url=jdbc:mysql://localhost:3308/springbootdb?useUnicode=true&characterEncoding=utf8&allowMultiQueries=true
spring.datasource.username=root
spring.datasource.password=mysql
spring.datasource.driver-class-name=com.mysql.jdbc.Driver

 

第三步  添加相关需要的jar

 

<dependency>
	<groupId>mysql</groupId>
	<artifactId>mysql-connector-java</artifactId>
	<scope>runtime</scope>
</dependency>
<!-- quartz -->
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-quartz</artifactId>
</dependency>

第四步 创建定时任务

    /**
     * 执行定时任务
     */
    @Override
    protected void executeInternal(JobExecutionContext context) throws JobExecutionException {
        // TODO Auto-generated method stub
        System.out.println("执行定时任务》》》"+new Date());
        String filePath="D:\\\\数据库文件\\\\";
        String dbName="springbootdb";//备份的数据库名
        String username="root";//用户名
        String password="mysql";//密码
        File uploadDir = new File(filePath);
        if (!uploadDir.exists())
            uploadDir.mkdirs();
        
        String cmd =  "mysqldump -u"+ username +"  -p "+password + dbName + " -r "
                + filePath + "/" + dbName+new java.util.Date().getTime()+ ".sql";
        try {
        Process process = Runtime.getRuntime().exec(cmd); 
            System.out.println("备份数据库成功!!!");         
        } catch (Exception e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
     
        }

    }

第五步  配置quartz，设置每10秒执行一次定时任务

@Configuration
public class QuartzConfig {
    @Bean
    public JobDetail teatQuartzDetail(){
        return JobBuilder.newJob(TestQuartz.class).withIdentity("testQuartz").storeDurably().build();
    }

    @Bean
    public Trigger testQuartzTrigger(){
        SimpleScheduleBuilder scheduleBuilder = SimpleScheduleBuilder.simpleSchedule()
                .withIntervalInSeconds(10)  //设置时间周期单位秒
                .repeatForever();
        return TriggerBuilder.newTrigger().forJob(teatQuartzDetail())
                .withIdentity("testQuartz")
                .withSchedule(scheduleBuilder)
                .build();
    }

}

第六步  运行项目

 备份成功！！！！！！！！！！！！！！！！！！！！
