Spring 带RoutingDataSource的Quartz JDBCJobStore

spring

Spring 带RoutingDataSource的Quartz JDBCJobStore,spring,quartz-scheduler,Spring,Quartz Scheduler,对于我的应用程序，我们使用spring的 org.springframework.jdbc.datasource.lookup.AbstractRoutingDataSource 根据请求的域URL配置和选择目标数据源 Eg: qa.example.com ==> target datasource = DB1 qa-test.example.com ==> target datasource = DB2 以下是相同的配置 @Bean(name = "d

对于我的应用程序，我们使用spring的 org.springframework.jdbc.datasource.lookup.AbstractRoutingDataSource

根据请求的域URL配置和选择目标数据源

    Eg: 

    qa.example.com ==> target datasource = DB1
    qa-test.example.com ==> target datasource = DB2

以下是相同的配置

@Bean(name = "dataSource")
    public DataSource dataSource() throws PropertyVetoException, ConfigurationException {
        EERoutingDatabase routingDB = new EERoutingDatabase();

        Map<Object, Object> targetDataSources = datasourceList();
        routingDB.setTargetDataSources(targetDataSources);

        return routingDB;
    }

public class EERoutingDatabase extends AbstractRoutingDataSource {

    @Override
    protected Object determineCurrentLookupKey() {
        // This is derived from the request's URL/Domain
        return SessionUtil.getDataSourceHolder();
    }
}

下面是quartz属性文件（ee quartz.properties）中的配置

启动应用程序时，发生以下异常

看来

Quartz正在尝试预先创建与我的数据源的连接。因为我的数据源不是具体的数据源（它的路由数据源），而且不知道要连接到哪个目标数据库（在配置时），所以它失败了

我们是否有任何规定，石英可以与RoutingDataSource一起使用？如果不是，下一个最好的办法是什么

理想情况下，您可以尝试将

SchedulerFactoryBean

设置为@Lazy

但是懒惰初始化似乎不起作用，注释中还列出了一个变通方法

之后动态创建

schedulerFactory

bean

ContextRefreshedEvent

在根上下文上收到

如果这样做有效，请告诉我们。
