SpringBoot2数据源的配置不起作用
我有一个 application.yml(!) 用于包含以下内容的配置:
spring:
datasource:
url: "jdbc:h2:file:./camunda-h2-database"
driverClassName: "org.h2.Driver"
username: "sa"
password: ""
这给了我错误消息:
2021-03-11T17:02:48,600 WARN [main] o.s.c.s.AbstractApplicationContext: Exception encountered during context initialization - cancelling refresh attempt: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'org.camunda.bpm.spring.boot.starter.CamundaBpmAutoConfiguration$ProcessEngineConfigurationImplDependingConfiguration': Unsatisfied dependency expressed through field 'processEngineConfigurationImpl'; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'processEngineConfigurationImpl' defined in class path resource [org/camunda/bpm/spring/boot/starter/CamundaBpmConfiguration.class]: Unsatisfied dependency expressed through method 'processEngineConfigurationImpl' parameter 0; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'camundaDatasourceConfiguration': Unsatisfied dependency expressed through field 'dataSource'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'javax.sql.DataSource' available: expected at least 1 bean which qualifies as autowire candidate.

这样做是有效的:
想法?:-)

重命名driverClassName为,driver-class-name因为在 Spring Boot 自动配置属性中 Kebab case 优先于 Camel case。
如果这没有帮助,请确保您没有关闭DataSourceAutoConfiguration功能。它通常看起来像
@SpringBootApplication(exclude = [DataSourceAutoConfiguration::class])
public class BootApplication { ... }
