如何使用默認 spring.datasource 啟動石英集群？

Question

我正在嘗試遵循https://docs.spring.io/spring-boot/docs/2.0.x/reference/html/boot-features-quartz.html和https://docs.spring.io/上的手冊spring-boot/docs/current/reference/html/io.html#io.quartz

默認情況下，使用內存中的 JobStore。 但是，如果 DataSource bean 在您的應用程序中可用並且 spring.quartz.job-store-type 屬性配置為 [with "jdbc"]，則可以配置基於 JDBC 的存儲。

我包括兩個自動配置器。 我的 pom.xml：

...
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-quartz</artifactId>
            <version>2.7.0</version>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-data-jpa</artifactId>
        </dependency>
        <dependency>
            <groupId>com.zaxxer</groupId>
            <artifactId>HikariCP</artifactId>
...

我的屬性文件包括

spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
spring.datasource.url=jdbc:mysql:...

spring.quartz.job-store-type=jdbc

當我啟動應用程序時，我看到 hikariCP 正在啟動到 spring.datasource url 的連接池......但是石英失敗，嘗試配置org.quartz.simpl.RAMJobStore時出現錯誤......看起來不正確。

這是否意味着 spring.datasource 和/或 hikariCP 不符合條件，就if a DataSource bean is available in your application ？

如果我嘗試強制 spring-quartz 使用數據庫：

org.quartz.jobStore.class=org.springframework.scheduling.quartz.LocalDataSourceJobStore

那么錯誤是：

...
2022-06-06 17:56:06.811 [main] WARN  o.s.s.quartz.LocalDataSourceJobStore - Database connection shutdown unsuccessful.
java.sql.SQLException: There is no DataSource named 'null'

Answer 1

您需要將spring-boot-starter-jdbc添加到 pom.xml 中：

 <dependency>
      <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-starter-jdbc</artifactId>
   </dependency>

注意：當您設置org.quartz.jobstore.class時，這意味着 Spring Framework 將不再設置DataSource 。 在這種情況下，您需要聲明Quartz將使用的DataSource bean：

import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.quartz.QuartzDataSource;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.boot.jdbc.DataSourceBuilder;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

import javax.sql.DataSource;


@Configuration
@EnableAutoConfiguration
public class QuartzConfiguration {

    @Bean
@QuartzDataSource
@ConfigurationProperties(prefix = "spring.datasource")
public DataSource quartzDataSource() {
    return DataSourceBuilder.create().build();
}
}

以及application.propeties文件中的以下屬性：

using.spring.schedulerFactory=true
spring.quartz.job-store-type=jdbc
spring.quartz.properties.org.quartz.jobStore.driverDelegateClass=org.quartz.impl.jdbcjobstore.PostgreSQLDelegate

注意：這里我提供了 PostgreSql 數據庫的示例
