我目前正在尝试SpringDataRedis,以便获取数据并将其放入redis存储库。但是,在使用 mvn spring-boot:run
,它总是返回错误并显示以下消息:
[ERROR] Failed to execute goal org.springframework.boot:spring-boot-maven-plugin:2.1.7.RELEASE:run (default-cli) on project networkprofile-bs-redis-poc: An exception occurred while running. null: InvocationTargetException: Invalid bean definition with name 'metadataRepository' defined in null: Cannot register bean definition [Root bean: class [org.springframework.data.redis.repository.support.RedisRepositoryFactoryBean]; scope=; abstract=false; lazyInit=false; autowireMode=0; dependencyCheck=0; autowireCandidate=true; primary=false; factoryBeanName=null; factoryMethodName=null; initMethodName=null; destroyMethodName=null] for bean 'metadataRepository': There is already [Root bean: class [org.springframework.data.jdbc.repository.support.JdbcRepositoryFactoryBean]; scope=; abstract=false; lazyInit=false; autowireMode=0; dependencyCheck=0; autowireCandidate=true; primary=false; factoryBeanName=null; factoryMethodName=null; initMethodName=null; destroyMethodName=null] bound. -> [Help 1]
我的代码中有两个存储库接口, MetadataRepository
以及 ProfileRepository
,由于某种原因,错误在这两者之间来回移动,并且 InvocationTargetException
.
元数据存储库
package xxx.repository;
import org.springframework.data.repository.CrudRepository;
import xxx.model.redis.Metadata;
public interface MetadataRepository extends CrudRepository<Metadata, String> {}
档案库
package xxx.repository;
import org.springframework.data.repository.CrudRepository;
import xxx.model.redis.Profile;
public interface ProfileRepository extends CrudRepository<Profile, String> {
Profile findByMsisdnAndProfile(String msisdn, String profile);

我设置了一些redis配置如下:
package xxx.config;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.redis.connection.RedisStandaloneConfiguration;
import org.springframework.data.redis.connection.lettuce.LettuceConnectionFactory;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.data.redis.repository.configuration.EnableRedisRepositories;
@Configuration
@EnableRedisRepositories
public class RedisConfig {
@Value("${xxx.redis.host}")
private String redisHost;
@Value("${xxx.redis.port}")
private int redisPort;
@Bean
public LettuceConnectionFactory lettuceConnectionFactory() {
RedisStandaloneConfiguration redisStandaloneConfiguration = new RedisStandaloneConfiguration(redisHost, redisPort);
return new LettuceConnectionFactory(redisStandaloneConfiguration);
}
@Bean
public RedisTemplate<String, Object> redisTemplate(){
RedisTemplate<String, Object> template = new RedisTemplate<>();
template.setConnectionFactory(lettuceConnectionFactory());
template.afterPropertiesSet();
return template;
}
}
我不太清楚是什么原因造成的,因为这与引发的类似问题不同 BeanDefinitionOverrideException
.
我的目标是让我的应用程序可以毫无问题地运行,所以我需要找出原因。也许我做得不对?
更新
我发现了 spring-boot-starter-data-jdbc
以及 spring-boot-starter-data-redis
在我的构建中引起冲突,导致 InvocationTargetException
. 排除jdbc依赖项后 InvocationTargetException
消失了。但是,这样做会破坏其他需要jdbc连接的模块。所以在我的例子中,我需要jdbc和redis依赖。

我被一个类似的问题困扰了将近两天,但最终还是解决了。问题是,当在一个项目中使用多个spring数据模块时,spring框架进入严格的存储库配置模式,并在下面使用不同的检测机制,以确定哪个存储库属于哪个持久性技术(这里解释)。
在您的例子中,使用了两个spring数据模块,即spring数据jdbc和spring数据redis。因此,项目中定义的profilerepository和metadatarepository可以用作spring数据jdbc和spring数据redis的存储库。解决这个问题的一种方法是使用特定于模块的注解。例如,要将profilerepository定义为与redis相关的存储库,必须将profile类定义为:
或者,如果要将profilerepository定义为与jdbc相关的存储库,则必须将profile类定义为:
