# quartz配置单独数据库
|
||
|
||
quartz默认安装时，她的包里面会有数据库相关内容，你可以自己去手动创建数据库，也可以使用自带的创建，这里以MySQL为例。
|
||
|
||
可能版本不一样，有的版本好像是不能自动创建的；我的版本是`2.3.2`。
|
||
|
||
这里主要说怎么连接数据库以及创建和连接数据库时一些问题。
|
||
|
||
```xml
|
||
<!-- quartz定时任务 -->
|
||
<dependency>
|
||
<groupId>org.quartz-scheduler</groupId>
|
||
<artifactId>quartz</artifactId>
|
||
<version>2.3.2</version>
|
||
</dependency>
|
||
<dependency>
|
||
<groupId>com.mchange</groupId>
|
||
<artifactId>c3p0</artifactId>
|
||
<version>0.9.5.5</version>
|
||
</dependency>
|
||
<!-- 直接找不到上下文 -->
|
||
<dependency>
|
||
<groupId>org.springframework</groupId>
|
||
<artifactId>spring-context-support</artifactId>
|
||
<version>6.1.6</version>
|
||
</dependency>
|
||
```
|
||

|
||
|
||
## quartz连接数据库
|
||
|
||
连接数据库如果不设置配置文件会使用默认数据库，包括在使用多数据源时，如果你使用的是多数据源配置，那么会自动找主数据库，在Service实现类上加上注解制定数据库是不行的，这也是毋庸置疑的。
|
||
|
||
如果需要两个数据库，想让quartz单独，需要写配置文件以及相关实现类。
|
||
|
||
### 配置数据库连接
|
||
|
||
`application.yml`中，需要将仓库类型设置为数据库表示以数据库作为存储。
|
||
|
||
```yml
|
||
quartz:
|
||
# 使用数据库连接
|
||
job-store-type: jdbc
|
||
jdbc:
|
||
# 是否设置数据库自动创建
|
||
initialize-schema: always
|
||
auto-startup: true
|
||
wait-for-jobs-to-complete-on-shutdown: true
|
||
overwrite-existing-jobs: false
|
||
```
|
||
|
||
> **这里自动创建需要注意，如果没有写类配置文件可以自动创建，但是写了就创建不了了。没有写之前我的项目是可以创建的，但是写了之后就无法自动创建了。**
|
||
>
|
||
> 如果不能自动创建可以创参考下面，我也将MySQL创建语句放在下面了。
|
||
>
|
||
> #### 手动创建数据库
|
||
>
|
||
> 手动去搜索包，找到里面你想要的数据库，数据库类型在下面图片，几乎主流数据库都有。
|
||
>
|
||
> > 数据库连接需要SQL文件，SQL文件在自带的包中也有，在这个文件夹下，之后只找到你的SQL版本。

### 配置文件编写
|
||
|
||
光写配置文件是没用的，这个配置文件写完，如果不写配置类是不生效的。
|
||
|
||
- `instanceName`这个要注意下，如果你的名称为现在的`quartzScheduler`，如果将这个名称换成`MyScheduler`那么你所制定所有的带`quartzScheduler`任务都不会执行，相反如果你的任务是`MyScheduler`但是你想执行之前任务是`quartzScheduler`也无法执行，只有当你的名称改为指定的才可以正常启动！！！
|
||
- 特别要注意`org.quartz.dataSource.xxx`后面的`xxx`是你的数据库名称！！！否则连接不上
|
||
|
||
|
||
|
||
```
|
||
# 就是上面所说的用处
|
||
org.quartz.scheduler.instanceName=MyScheduler
|
||
# 最大线程数
|
||
org.quartz.threadPool.threadCount=5
|
||
org.quartz.jobStore.class=org.quartz.impl.jdbcjobstore.JobStoreTX
|
||
org.quartz.jobStore.driverDelegateClass=org.quartz.impl.jdbcjobstore.StdJDBCDelegate
|
||
# 数据库连接的前缀，如果你是默认按照官方数据库生成就写这个
|
||
org.quartz.jobStore.tablePrefix=QRTZ_
|
||
# 连接的数据库名称
|
||
org.quartz.jobStore.dataSource=quartz
|
||
# 数据库连接驱动
|
||
org.quartz.dataSource.quartz.driver=com.mysql.cj.jdbc.Driver
|
||
# 数据库连接地址
|
||
org.quartz.dataSource.quartz.URL=jdbc:mysql://192.168.3.98:3306/quartz?serverTimezone=GMT%2B8&useSSL=false&characterEncoding=utf-8&allowPublicKeyRetrieval=true
|
||
# 数据库连接用户名
|
||
org.quartz.dataSource.quartz.user=root
|
||
# 数据库连接密码
|
||
org.quartz.dataSource.quartz.password=123456
|
||
# 最大连接数
|
||
org.quartz.dataSource.quartz.maxConnections=5
|
||
```
|
||
|
||
> ### 注意事项
|
||
>
|
||
> 在连接数据库时需要注意这下面几行配置当中的`xxx.xxxx.xxx.quartz.xxx`，其中`quartz`指的是你的数据库名称
|
||
>
|
||
> ```properties
|
||
> org.quartz.jobStore.dataSource=quartz
|
||
> org.quartz.dataSource.quartz.driver=com.mysql.cj.jdbc.Driver
|
||
> org.quartz.dataSource.quartz.URL=jdbc:mysql://192.168.3.98:3306/quartz?serverTimezone=GMT%2B8&useSSL=false&characterEncoding=utf-8&allowPublicKeyRetrieval=true
|
||
> org.quartz.dataSource.quartz.user=root
|
||
> org.quartz.dataSource.quartz.password=123456
|
||
> org.quartz.dataSource.quartz.maxConnections=5
|
||
> ```
|
||
>
|
||
> #### 例子
|
||
>
|
||
> 如果你的数据库名称叫`bunnyQuartz`，那么下面应当换成
|
||
>
|
||
> ```properties
|
||
> org.quartz.jobStore.dataSource=bunnyQuartz
|
||
> org.quartz.dataSource.bunnyQuartz.driver=com.mysql.cj.jdbc.Driver
|
||
> org.quartz.dataSource.bunnyQuartz.URL=jdbc:mysql://192.168.3.98:3306/bunnyQuartz?serverTimezone=GMT%2B8&useSSL=false&characterEncoding=utf-8&allowPublicKeyRetrieval=true
|
||
> org.quartz.dataSource.bunnyQuartz.user=root
|
||
> org.quartz.dataSource.bunnyQuartz.password=123456
|
||
> org.quartz.dataSource.bunnyQuartz.maxConnections=5
|
||
> ```
|
||
>
|
||
|
||
### 配置类编写
|
||
|
||
#### 工厂类
|
||
|
||
```java
|
||
package cn.bunny.service.quartz;
|
||
|
||
import lombok.extern.slf4j.Slf4j;
|
||
import org.jetbrains.annotations.NotNull;
|
||
import org.quartz.spi.TriggerFiredBundle;
|
||
import org.springframework.beans.factory.annotation.Autowired;
|
||
import org.springframework.beans.factory.config.AutowireCapableBeanFactory;
|
||
import org.springframework.scheduling.quartz.AdaptableJobFactory;
|
||
import org.springframework.stereotype.Component;
|
||
|
||
@Component
|
||
@Slf4j
|
||
public class QuartzJobFactory extends AdaptableJobFactory {
|
||
|
||
// 这个对象Spring会帮我们自动注入进来
|
||
@Autowired
|
||
private AutowireCapableBeanFactory capableBeanFactory;
|
||
|
||
// 重写创建Job任务的实例方法
|
||
@NotNull
|
||
@Override
|
||
protected Object createJobInstance(@NotNull TriggerFiredBundle bundle) throws Exception {
|
||
Object jobInstance = super.createJobInstance(bundle);
|
||
// 通过以下方式，解决Job任务无法使用Spring中的Bean问题
|
||
capableBeanFactory.autowireBean(jobInstance);
|
||
return super.createJobInstance(bundle);
|
||
}
|
||
}
|
||
```
|
||
|
||
#### 配置类
|
||
|
||
我定的延迟，5秒感觉要有点久了，我想防止程序一开始就启动想让她往后面一点。
|
||
|
||
其次要注意你的配置文件名称一定要和`ClassPathResource`中名称一样！！！
|
||
|
||
```java
|
||
package cn.bunny.service.quartz;
|
||
|
||
import org.quartz.Scheduler;
|
||
import org.springframework.beans.factory.annotation.Autowired;
|
||
import org.springframework.beans.factory.config.PropertiesFactoryBean;
|
||
import org.springframework.context.annotation.Bean;
|
||
import org.springframework.context.annotation.Configuration;
|
||
import org.springframework.core.io.ClassPathResource;
|
||
import org.springframework.scheduling.quartz.SchedulerFactoryBean;
|
||
|
||
import java.io.IOException;
|
||
import java.util.Properties;
|
||
|
||
@Configuration
|
||
public class QuartzConfiguration {
|
||
|
||
@Autowired
|
||
private QuartzJobFactory quartzJobFactory;
|
||
|
||
//创建调度器工厂
|
||
@Bean
|
||
public SchedulerFactoryBean schedulerFactoryBean(){
|
||
//1.创建SchedulerFactoryBean
|
||
//2.加载自定义的quartz.properties配置文件
|
||
//3.设置MyJobFactory
|
||
SchedulerFactoryBean factoryBean=new SchedulerFactoryBean();
|
||
try {
|
||
factoryBean.setAutoStartup(true);
|
||
factoryBean.setStartupDelay(5);//延时5秒启动
|
||
factoryBean.setQuartzProperties(quartzProperties());
|
||
factoryBean.setJobFactory(quartzJobFactory);
|
||
return factoryBean;
|
||
} catch (IOException e) {
|
||
throw new RuntimeException(e);
|
||
}
|
||
}
|
||
|
||
@Bean
|
||
public Properties quartzProperties() throws IOException {
|
||
PropertiesFactoryBean propertiesFactoryBean=new PropertiesFactoryBean();
|
||
propertiesFactoryBean.setLocation(new ClassPathResource("/quartz.properties"));
|
||
propertiesFactoryBean.afterPropertiesSet();
|
||
return propertiesFactoryBean.getObject();
|
||
}
|
||
|
||
@Bean(name="scheduler")
|
||
public Scheduler scheduler(){
|
||
return schedulerFactoryBean().getScheduler();
|
||
}
|
||
}
|
||
```
|
||
|
||
> 之前尝试过将这个改成`yml`文件但是必须要添加一次任务才可以启动，暂不清楚原因。
|
||
|

## 常见问题
|
||
|
||
### 连接中报错
|
||
|
||
缺少依赖导致无法启动。
|
||
|
||
如果报错类型有下面的，添加包，包的版本根据你的项目而定，我的是SpringBoot3.x的
|
||
|
||
```xml
|
||
<dependency>
|
||
<groupId>com.mchange</groupId>
|
||
<artifactId>c3p0</artifactId>
|
||
<version>0.9.5.5</version> <!-- 请使用适合你项目的版本 -->
|
||
</dependency>
|
||
```
|
||
|
||
如果报错类型有下面的
|
||

||
