springboot创建的web项目整合Quartz框架的项目实践

Java开发
2023-01-23

本文主要介绍了springboot创建的web项目整合Quartz框架的项目实践，文中通过示例代码介绍的非常详细，对大家的学习或者工作具有一定的参考学习价值，需要的朋友们下面随着小编来一起学习学习吧

介绍

Quartz是OpenSymphony开源组织在Job scheduling领域又一个开源项目，它可以与J2EE与J2SE应用程序相结合也可以单独使用。Quartz可以用来创建简单或为运行十个，百个，甚至是好几万个Jobs这样复杂的程序。Jobs可以做成标准的Java组件或EJBs。Quartz的最新版本为Quartz 2.3.2。

quartz可以在某一个有规律的时间点干某件事，是一个任务调度框架，可以被集成到java的各种应用中使用，quartz框架可以支持分布式任务处理

基于springboot创建的web项目整合Quartz框架

整体代码结构

导入依赖

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

创建quartz_demo数据库，执行tables_mysql_innodb.sql文件创建对应表，下面是文件内容

#
# In your Quartz properties file, you'll need to set
# org.quartz.jobStore.driverDelegateClass = org.quartz.impl.jdbcjobstore.StdJDBCDelegate
#
#
# By: Ron Cordell - roncordell
#  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.

        }
    }
}

创建一个Job实现类，只是一个简单实现类，没有对方法添加参数

@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("正在执行任务");
        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("已结束任务");
        System.out.println();
    }
}

创建最终任务执行类，执行函数级别的定时任务，数据库中的invoke_target是和这里放入spring中的名称相同的，quartz_target.hello最终执行的函数就是hello函数

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

    @Resource
    private Scheduler scheduler;

    public void hello() throws Exception {
        System.out.println("[job]实例执行...hello..." + System.currentTimeMillis());
    }

    public void action() throws Exception {
        System.out.println("[job]实例执行...action..." + System.currentTimeMillis());
    }
}

最终代码结构

启动spring boot之后的任务状态

使用postman工具类添加一个任务

然后在代码中添加一个对应的方法

重新启动springboot的运行结果

理论上使用这样的反射方式可以运行任何代码的
