springboot創建的web項目整合Quartz框架的項目實踐

Posted on 2022-06-21 by WalkonNet

介紹

Quartz是OpenSymphony開源組織在Job scheduling領域又一個開源項目，它可以與J2EE與J2SE應用程序相結合也可以單獨使用。Quartz可以用來創建簡單或為運行十個，百個，甚至是好幾萬個Jobs這樣復雜的程序。Jobs可以做成標準的Java組件或EJBs。Quartz的最新版本為Quartz 2.3.2。

quartz可以在某一個有規律的時間點幹某件事，是一個任務調度框架，可以被集成到java的各種應用中使用，quartz框架可以支持分佈式任務處理

基於springboot創建的web項目整合Quartz框架

整體代碼結構

在這裡插入圖片描述

導入依賴

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-quartz</artifactId>
        </dependency>

創建quartz_demo數據庫，執行tables_mysql_innodb.sql文件創建對應表，下面是文件內容

#
# In your Quartz properties file, you'll need to set
# org.quartz.jobStore.driverDelegateClass = org.quartz.impl.jdbcjobstore.StdJDBCDelegate

#  I didn't see this anywhere, so I thought I'd post it here. This is the script from Quartz to create the tables in a MySQL database, modified to use INNODB instead of MYISAM.

}

創建一個Job實現類，隻是一個簡單實現類，沒有對方法添加參數

@Slf4j
@Component
public class QuartzJobImpl implements Job {

    @Autowired
    private ApplicationContext context;

    @SneakyThrows
    @Override
    public void execute(JobExecutionContext jobExecutionContext) throws JobExecutionException {
        SysJob sysJob = new SysJob();
        BeanUtils.copyProperties(jobExecutionContext.getMergedJobDataMap().get("QuartzJobExecutionData"), sysJob);
        log.info("正在執行任務");
        String invokeTarget = sysJob.getInvokeTarget();
        String beanName = invokeTarget.split("\\.")[0];
        String methodName = invokeTarget.split("\\.")[1];
        Object bean = context.getBean(beanName);
        Class<?> clazz = bean.getClass();
        Method method = clazz.getMethod(methodName);
        method.invoke(bean);
        log.info("已結束任務");
        System.out.println();
    }
}

創建最終任務執行類，執行函數級別的定時任務，數據庫中的invoke_target是和這裡放入spring中的名稱相同的，quartz_target.hello最終執行的函數就是hello函數

@Slf4j
@Component("quartz_target")
public class QuartzJobExe {

    @Resource
    private Scheduler scheduler;

    public void hello() throws Exception {
        System.out.println("[job]實例執行...hello..." + System.currentTimeMillis());
    }

    public void action() throws Exception {
        System.out.println("[job]實例執行...action..." + System.currentTimeMillis());
    }
}

最終代碼結構

啟動spring boot之後的任務狀態

使用postman工具類添加一個任務

在這裡插入圖片描述

然後在代碼中添加一個對應的方法

在這裡插入圖片描述

重新啟動springboot的運行結果

在這裡插入圖片描述

理論上使用這樣的反射方式可以運行任何代碼的
