Java 考虑定义一个类型的豆和*x27；sessionmanager.repositories.SessionRepository'；在您的配置中

我目前正在用Redis试用Spring boot应用程序。当我尝试执行该程序时，我遇到了一个与Spring boot有关的问题，涉及Redis存储库

当我运行应用程序时，出现以下错误：

尝试使用@ComponentScan和@EnableRedisRepositories更新主类

dependencies {
    compile('org.springframework.boot:spring-boot-starter-data-redis')
    compile('org.springframework.boot:spring-boot-starter-web')
    providedRuntime('org.springframework.boot:spring-boot-starter-tomcat')
    testCompile('org.springframework.boot:spring-boot-starter-test')
}

package mezg.mezos.sessionmanager;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.data.redis.repository.configuration.EnableRedisRepositories;

@SpringBootApplication
@EnableAutoConfiguration
@ComponentScan({"mezg.mezos.sessionmanager","mezg.mezos.sessionmanager.controller","mezg.mezos.sessionmanager.services","mezg.mezos.sessionmanager.repositories"})
@EnableRedisRepositories("mezg.mezos.sessionmanager.repositories")
public class SessionStoreApplication {

    public static void main(String[] args) {
        SpringApplication.run(SessionStoreApplication.class, args);
    }
