我正在通過參考https://github.com/spring-petclinic/spring-petclinic-microservices 來開發(fā)微服務(wù)代碼。我能夠成功運(yùn)行所有模塊，但出現(xiàn)以下錯(cuò)誤。導(dǎo)入 de.codecentric.boot.admin.server.config.EnableAdminServer 無法解析從spring-petclinic-admin-server模塊中，我收到以下錯(cuò)誤。import de.codecentric.boot.admin.server.config.EnableAdminServer;@Configuration@EnableAutoConfiguration@EnableAdminServer@EnableDiscoveryClientpublic class SpringBootAdminApplication {    public static void main(String[] args) {        SpringApplication.run(SpringBootAdminApplication.class, args);    }}我能夠啟動其他微服務(wù)模塊。pom.xml<parent>        <groupId>org.springframework.samples</groupId>        <artifactId>spring-petclinic-microservices</artifactId>        <version>2.0.4</version>    </parent>    <properties>        <spring-boot-admin.version>2.0.1</spring-boot-admin.version>        <docker.image.exposed.port>9090</docker.image.exposed.port>        <docker.image.dockerfile.dir>${basedir}/../docker</docker.image.dockerfile.dir>    </properties>    <dependencies>        <!-- Spring Boot -->        <dependency>            <groupId>org.springframework.boot</groupId>            <artifactId>spring-boot-starter</artifactId>        </dependency>        <dependency>            <groupId>org.springframework.cloud</groupId>            <artifactId>spring-cloud-starter-config</artifactId>        </dependency>        <dependency>            <groupId>org.springframework.cloud</groupId>            <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>        </dependency>        <!-- Spring Boot Admin -->        <dependency>            <groupId>de.codecentric</groupId>            <artifactId>spring-boot-admin-starter-server</artifactId>            <version>${spring-boot-admin.version}</version>        </dependency>        <dependency>            <groupId>de.codecentric</groupId>            <artifactId>spring-boot-admin-server-ui</artifactId>            <version>${spring-boot-admin.version}</version>        </dependency>
