从spring-boot 2.x.x开始，他们开始提供spring-boot-starter-quartz，非常棒！开箱即用它可以进行内存存储。我想将其更改为集群环境，但我认为配置存在问题主要是因为我需要将qrtz_表放在与默认数据源不同的模式中。有没有人有使用备用数据源的例子？我目前正在尝试设置属性字段（如下所示），但它们似乎没有被配置bean接收。任何帮助表示赞赏。

答案 0 :(得分：1)
您必须使用石英属性的正确属性。 您的财产遗失... org.quartz ...
对于none-yml表示法，请尝试使用threadCount：
spring.quartz.properties.org.quartz.threadPool.threadCount=25
对于yml表示法：
在'属性'下添加两层，例如
spring:
quartz:
properties:
org:
quartz:
threadPool:
threadCount : 25
答案 1 :(得分：-2)
Application.yml文件：
spring:
jpa:
hibernate:
ddl-auto: none
datasource:
url: jdbc:mysql://127.0.0.1:3306/Quartz
username: Your Username
password: Your Password
quartz:
scheduler:
instanceName: Scheduler
threadPool:
class: org.quartz.simpl.SimpleThreadPool
threadCount: 3
context:
key:
QuartzTopic: QuartzPorperties
jobStore:
driver: com.mysql.jdbc.Driver
class: org.quartz.impl.jdbcjobstore.JobStoreTX
driverDelegateClass: org.quartz.impl.jdbcjobstore.StdJDBCDelegate
misfireThreshold: 6000
tablePrefix: QRTZ_
接下来创建一个Configuration类，它从yml文件中读取这些属性，然后创建一个Scheduler Bean：
@Configuration
public class SchedulerConfig {
private final Logger logger = LoggerFactory.getLogger(this.getClass());
@Value("${quartz.scheduler.instanceName}")
private String instanceName;
@Value("${quartz.threadPool.class}")
private String threadClass;
@Value("${quartz.threadPool.threadCount}")
private String threadCount;
@Value("${quartz.context.key.QuartzTopic}")
private String quartzTopic;
@Value("${quartz.jobStore.class}")
private String jobStoreClass;
@Value("${quartz.jobStore.driverDelegateClass}")
private String driverDelegateClass;
@Value("${quartz.jobStore.misfireThreshold}")
private String misfireThreshold;
@Value("${quartz.jobStore.tablePrefix}")
private String tablePrefix;
@Value("${quartz.jobStore.driver}")
private String dataSourceDriver;
@Value("${spring.datasource.url}")
private String dataSourceUrl;
@Value("${spring.datasource.username}")
private String dataSourceUsername;
@Value("${spring.datasource.password}")
private String databasePassword;
@Bean({"Scheduler"})
public Scheduler getScheduler() {
Scheduler scheduler = null;
try {
StdSchedulerFactory factory = new StdSchedulerFactory();
Properties props = new Properties();
props.put("org.quartz.scheduler.instanceName", instanceName);
props.put("org.quartz.threadPool.class", threadClass);
props.put("org.quartz.threadPool.threadCount", threadCount);
props.put("org.quartz.context.key.QuartzTopic", quartzTopic);
props.put("org.quartz.jobStore.class", jobStoreClass);
props.put("org.quartz.jobStore.driverDelegateClass", driverDelegateClass);
props.put("quartz.jobStore.misfireThreshold", misfireThreshold);
props.put("org.quartz.jobStore.tablePrefix", tablePrefix);
props.put("org.quartz.jobStore.dataSource", "myDS");
props.put("org.quartz.dataSource.myDS.driver", dataSourceDriver);
props.put("org.quartz.dataSource.myDS.URL", dataSourceUrl);
props.put("org.quartz.dataSource.myDS.user", dataSourceUsername);
props.put("org.quartz.dataSource.myDS.password", databasePassword);
props.put("org.quartz.dataSource.myDS.maxConnections", "10");
factory.initialize(props);
scheduler = factory.getScheduler();
scheduler.start();
scheduler.resumeAll(); // This is to resume the entire scheduler when a new build is deployed
} catch (Exception e) {
logger.error("{} - SchedulerConfig class - getScheduler() - Error creating Scheduler instance: {}",
appName, e);
}
return scheduler;
}
}
最后，在你想要的任何类中使用如下的Bean：
@Autowired
private Scheduler scheduler;
