spring cloud项目启动报 The bean ‘dataSource‘, defined in BeanDefinition defined in class path resource

这是因为Finchley和springboot版本不兼容

<parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>2.1.12.RELEASE</version> <relativePath/> </parent>

将项目里Finchley修改为Greenwich 修改之前

<dependencyManagement> <dependencies> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-dependencies</artifactId> <version>Finchley.RELEASE</version> //将Finchley修改为Greenwich <type>pom</type> <scope>import</scope> </dependency> </dependencies> </dependencyManagement>

修改之后

<dependencyManagement> <dependencies> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-dependencies</artifactId> <version>Greenwich.RELEASE</version> <type>pom</type> <scope>import</scope> </dependency> </dependencies> </dependencyManagement>
