如何解决“在类路径资源中定义的 BeanDefinition 中定义的 bean 'dataSource'”？

Question

我的 Spring 微服务原型应用程序无法启动并显示以下消息：

***************************
APPLICATION FAILED TO START
***************************

Description:

The bean 'dataSource', defined in BeanDefinition defined in class path resource [org/springframework/boot/autoconfigure/jdbc/DataSourceConfiguration$Hikari.class], could not be registered. A bean with that name has already been defined in class path resource [org/springframework/boot/autoconfigure/jdbc/DataSourceConfiguration$Hikari.class] and overriding is disabled.

Action:

Consider renaming one of the beans or enabling overriding by setting spring.main.allow-bean-definition-overriding=true

应用依赖如下：

dependencies {
implementation 'org.springframework.boot:spring-boot-starter-data-jpa'
implementation 'org.springframework.boot:spring-boot-starter-security'

implementation 'org.springframework.boot:spring-boot-starter-webflux'
compileOnly 'org.projectlombok:lombok'
runtimeOnly 'org.springframework.boot:spring-boot-devtools'
runtimeOnly 'com.h2database:h2'
annotationProcessor 'org.projectlombok:lombok'

implementation 'org.springframework.boot:spring-boot-starter-web'
implementation 'org.springframework.cloud:spring-cloud-starter-config'
implementation 'org.springframework.cloud:spring-cloud-starter-netflix-eureka-client'

testImplementation 'org.springframework.boot:spring-boot-starter-test'
testImplementation 'io.projectreactor:reactor-test'
testImplementation 'org.springframework.security:spring-security-test'
}

我假设 data-jpa 和 h2 都带有数据源。我之前有过类似的组合，没有这个问题。我想可以通过在依赖项之一中排除数据源来解决问题。经过网上搜索，我没有找到它是如何工作的。

有什么建议吗？

您可以在主类中添加以下内容：

@EnableAutoConfiguration(exclude={DataSourceAutoConfiguration.class})
