quart分布式使用

對(duì)于高可用、任務(wù)數(shù)比較多的系統(tǒng)，后臺(tái)任務(wù)需要部署多個(gè)，但是部署多個(gè)就可能出現(xiàn)一個(gè)任務(wù)跑多次，這就需要控制多臺(tái)服務(wù)器，每次只能有一個(gè)任務(wù)運(yùn)行。quartz利用mysql支持分布式部署。這篇文章只講spring boot quart分布式使用。還是利用上一篇的job。

spring boot quartz分布式使用

1. pom.xml配置

新增mysql驅(qū)動(dòng)和druid數(shù)據(jù)源

<dependency>
  <groupId>org.springframework.boot</groupId>
  <artifactId>spring-boot-starter-jdbc</artifactId>
  <exclusions>
    <exclusion>
      <groupId>com.zaxxer</groupId>
      <artifactId>HikariCP</artifactId>
    </exclusion>
  </exclusions>
</dependency>

<dependency>
  <groupId>mysql</groupId>
  <artifactId>mysql-connector-java</artifactId>
  <version>8.0.11</version>
</dependency>

<dependency>
  <groupId>com.alibaba</groupId>
  <artifactId>druid-spring-boot-starter</artifactId>
  <version>1.1.18</version>
</dependency>

2. application.yaml配置

新增application.yaml文件,聲明quartz使用數(shù)據(jù)庫(kù)方式

spring:
  quartz:
    job-store-type: jdbc
  datasource:
    druid:
      url: 
      username: 
      password:

3. 創(chuàng)建表

創(chuàng)建quartz需要的相關(guān)表，創(chuàng)建語(yǔ)句在/org/quartz-scheduler/quartz/2.3.1/quartz-2.3.1.jar!/org/quartz/impl/jdbcjobstore/tables_mysql.sql

#
# Quartz seems to work best with the driver mm.mysql-2.0.7-bin.jar
#
# PLEASE consider using mysql with innodb tables to avoid locking issues
#
# In your Quartz properties file, you'll need to set
# org.quartz.jobStore.driverDelegateClass = org.quartz.impl.jdbcjobstore.StdJDBCDelegate
#

4. 數(shù)據(jù)庫(kù)配置

增加數(shù)據(jù)源配置，在application.yaml中增加數(shù)據(jù)庫(kù)配置，因?yàn)橐氲氖莇ruid-spring-boot-starter配置，增加數(shù)據(jù)庫(kù)配置后會(huì)自動(dòng)創(chuàng)建數(shù)據(jù)源，但是為了區(qū)分應(yīng)用中的數(shù)據(jù)和quartz需要的數(shù)據(jù)源，這里建議使用自定義的數(shù)據(jù)源bean。@QuartzDataSource注解是spring boot quart用于識(shí)別的數(shù)據(jù)源，相當(dāng)于Spring的@Qualifier注解。

DBConfig.java

@Configuration
public class DBConfig {

    @Bean
    @QuartzDataSource
    public DataSource quartzDatasource() {
        return DruidDataSourceBuilder.create().build();
    }
}

5. 啟動(dòng)quartz

@SpringBootApplication
public class SpringBootQuartz {

    public static void main(String[] args) {
        SpringApplication.run(SpringBootQuartz.class, args);
    }
}
