我是Java框架的新手。我正在尝试使用配置服务中的配置属性，并遵循本教程。我尝试添加两个依赖项，一个是spring-cloud-config-client，另一个是spring-cloud-starter-bootstrap，但是每当我运行应用程序时，都会得到下面的错误

您缺少了spring-cloud-loadbalancer的依赖项
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-loadbalancer</artifactId>
<version>3.1.3</version>
</dependency>将这个添加到您的pom.xml中应该可以解决这个问题。

有时发生这种情况是因为所使用的版本不兼容。将这两行添加到pom.xml中的属性中
<spring.boot.dependencies.version>2.5.7</spring.boot.dependencies.version>
<spring.cloud-version>2020.0.3</spring.cloud-version>然后添加依赖关系管理。
<dependencyManagement>
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-dependencies</artifactId>
<version>${spring.boot.dependencies.version}</version>
<scope>import</scope>
<type>pom</type>
</dependency>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-dependencies</artifactId>
<version>${spring.cloud-version}</version>
<type>pom</type>
<scope>import</scope>
</dependency>
</dependencies>
</dependencyManagement>另外，需要注意的是Spring (即2.5.7)和Spring (即2020.0.3)的版本。它们应该相互兼容。
