springboot-task's Introduction

SpringBoot-task

基于spring-boot 2.x + quartz 的CRUD任务管理系统.

开发环境

JDK1.8、Maven、IDEA

技术栈

SpringBoot 2.1.0.RELEASE、thymeleaf 3.0.9、quartz 2.3.0、iview、vue、layer、AdminLTE、bootstrap

启动说明

  • 项目使用的数据库为MySql,选择resources/sql中的tables_mysql_innodb.sql文件初始化数据库信息。
  • 在resources/application.properties 以及quartz.properties文件中替换为自己的数据源。
  • 运行Application main方法启动项目,项目启动会自动创建一个测试任务 见:TaskRunner.java。
  • 项目访问地址:http://localhost:8080/quartz

配置(spring-boot 2.x)

项目配置:

# spring boot 2.x
server.servlet.context-path=/quartz

thymeleaf配置:

#spring boot 2.x
spring.thymeleaf.mode=HTML

Hibernate配置:

# spring boot 2.x JPA 依赖  Hibernate 5
# Hibernate 4 naming strategy fully qualified name. Not supported with Hibernate 5.
spring.jpa.hibernate.naming.strategy = org.hibernate.cfg.ImprovedNamingStrategy
# stripped before adding them to the entity manager)
spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.MySQL5Dialect
# Hibernate 5
spring.jpa.hibernate.naming.implicit-strategy=org.hibernate.boot.model.naming.ImplicitNamingStrategyLegacyJpaImpl
spring.jpa.hibernate.naming.physical-strategy=org.hibernate.boot.model.naming.PhysicalNamingStrategyStandardImpl

quartz配置:

# spring boot 2.x 已集成Quartz,无需自己配置
spring.quartz.job-store-type=jdbc
spring.quartz.properties.org.quartz.scheduler.instanceName=clusteredScheduler
spring.quartz.properties.org.quartz.scheduler.instanceId=AUTO
spring.quartz.properties.org.quartz.jobStore.class=org.quartz.impl.jdbcjobstore.JobStoreTX
spring.quartz.properties.org.quartz.jobStore.driverDelegateClass=org.quartz.impl.jdbcjobstore.StdJDBCDelegate
spring.quartz.properties.org.quartz.jobStore.tablePrefix=QRTZ_
spring.quartz.properties.org.quartz.jobStore.isClustered=true
spring.quartz.properties.org.quartz.jobStore.clusterCheckinInterval=10000
spring.quartz.properties.org.quartz.jobStore.useProperties=false
spring.quartz.properties.org.quartz.threadPool.class=org.quartz.simpl.SimpleThreadPool
spring.quartz.properties.org.quartz.threadPool.threadCount=10
spring.quartz.properties.org.quartz.threadPool.threadPriority=5
spring.quartz.properties.org.quartz.threadPool.threadsInheritContextClassLoaderOfInitializingThread=true

默认首页配置:

/**
 * 配置首页 spring boot 2.x
 */
@Configuration
public class MyAdapter extends WebMvcConfigurerAdapter{
    @Override
    public void addViewControllers( ViewControllerRegistry registry ) {
        registry.addViewController( "/" ).setViewName( "forward:/login.shtml" );
        registry.setOrder( Ordered.HIGHEST_PRECEDENCE );
        super.addViewControllers( registry );
    } 
}
/**
 * 配置首页(在SpringBoot2.0及Spring 5.0 WebMvcConfigurerAdapter以被废弃 
 * 建议实现WebMvcConfigurer接口)
 */
@Configuration
public class MyAdapter implements WebMvcConfigurer{
    @Override
    public void addViewControllers( ViewControllerRegistry registry ) {
        registry.addViewController( "/" ).setViewName( "forward:/login.shtml" );
        registry.setOrder( Ordered.HIGHEST_PRECEDENCE );
    } 
}

问题:

/**
	 * Set a strategy for handling the query results. This can be used to change
	 * "shape" of the query result.
	 *
	 * @param transformer The transformer to apply
	 *
	 * @return this (for method chaining)
	 *
	 * @deprecated (since 5.2)
	 * @todo develop a new approach to result transformers
	 */
	@Deprecated
	Query<R> setResultTransformer(ResultTransformer transformer);

hibernate 5.2 废弃了 setResultTransformer\

替换为: NativeQueryImplementor setResultTransformer(ResultTransformer transformer)

集群测试

打开quartz集群配置:

# 打开集群配置
spring.quartz.properties.org.quartz.jobStore.isClustered:true
# 设置集群检查间隔20s
spring.quartz.properties.org.quartz.jobStore.clusterCheckinInterval = 2000  

本地跑两个项目,分别设置不同的端口8081和8082,启动成功以后,会发现只有一个任务在跑,然后杀掉在跑的任务,你会发现另一个项目会检测到集群中的一个任务挂了,然后接管任务。

扩展

Quartz API核心接口有:

  • Scheduler – 与scheduler交互的主要API;
  • Job – 你通过scheduler执行任务,你的任务类需要实现的接口;
  • JobDetail – 定义Job的实例;
  • Trigger – 触发Job的执行;
  • JobBuilder – 定义和创建JobDetail实例的接口;
  • TriggerBuilder – 定义和创建Trigger实例的接口;
