SpringBoot - BeanDefinitionOverrideException:无效的Bean定义
我正在尝试使用 Spring Boot 在本地设置 DynamoDB。最初,我启动了设置,并能够通过存储库写入/保存到 DynamoDB。从那时起,我添加了更多的类来构建我的应用程序。现在,当我尝试启动应用程序时,我收到以下异常:
org.springframework.beans.factory.support.BeanDefinitionOverrideException: Invalid bean definition with name 'agentRepository' defined in null: Cannot register bean definition [Root bean: class [org.socialsignin.spring.data.dynamodb.repository.support.DynamoDBRepositoryFactoryBean]; scope=; abstract=false; lazyInit=false; autowireMode=0; dependencyCheck=0; autowireCandidate=true; primary=false; factoryBeanName=null; factoryMethodName=null; initMethodName=null; destroyMethodName=null] for bean 'agentRepository': There is already [Root bean: class [org.socialsignin.spring.data.dynamodb.repository.support.DynamoDBRepositoryFactoryBean]; scope=; abstract=false; lazyInit=false; autowireMode=0; dependencyCheck=0; autowireCandidate=true; primary=false; factoryBeanName=null; factoryMethodName=null; initMethodName=null; destroyMethodName=null] bound.
我已经广泛搜索了SO和互联网,但没有任何有用的解决方案。错误消息也具有误导性。
我的项目属于以下层次结构
ai.test.as
- as
- agent
- business
- intent
- exception
- Agent.java
- AgentDTO.java
- AgentRespository.java
- AgentController.java
- AgentService.java
- AgentServiceImpl.java
- config
- DynamoDBConfig.java
DynamoDBConfig.java
package ai.test.as.config;
import ai.test.as.agent.AgentRepository;
import ai.test.as.agent.intent.template.TemplateRepository;
import com.amazonaws.auth.AWSCredentials;
import com.amazonaws.auth.BasicAWSCredentials;
import com.amazonaws.services.dynamodbv2.AmazonDynamoDB;
import com.amazonaws.services.dynamodbv2.AmazonDynamoDBClient;
import org.socialsignin.spring.data.dynamodb.repository.config.EnableDynamoDBRepositories;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
@Configuration
@EnableDynamoDBRepositories(basePackageClasses = {AgentRepository.class})
public class DynamoDBConfig
{
@Value("${aws.dynamodb.endpoint}")
private String dynamoDBEndpoint;
@Value("${aws.auth.accesskey}")
private String awsAccessKey;
@Value("${aws.auth.secretkey}")
private String awsSecretKey;
@Bean
public AmazonDynamoDB amazonDynamoDB()
{
AmazonDynamoDB dynamoDB = new AmazonDynamoDBClient(getAwsCredentials());
dynamoDB.setEndpoint(dynamoDBEndpoint);
return dynamoDB;
}
@Bean
public AWSCredentials getAwsCredentials()
{
return new BasicAWSCredentials(awsAccessKey, awsSecretKey);
}
}
代理存储库.java
package ai.test.as.agent;
import ai.test.as.agent.Agent;
import org.socialsignin.spring.data.dynamodb.repository.EnableScan;
import org.springframework.data.repository.CrudRepository;
@EnableScan
public interface AgentRepository extends CrudRepository<Agent, String>
{
}
代理控制器.java(使用代理存储库的位置)
@RestController
@RequestMapping(value = "/v1/agents")
public class AgentController
{
@Autowired
private AgentRepository agentRepository;
@RequestMapping(value = "/test", method = RequestMethod.POST)
public void test()
{
Agent agent = new Agent();
agent.setAgentNumber("123456");
agent.setId(1);
agentRepository.save(agent);
}
}
春天建议如下: .> The bean 'agentRepository', defined in null, could not be registered. A bean with that name has already been defined in null and overriding is disabled
这是什么意思?是因为我的应用程序配置中出现问题吗?另外,它怎么可能已经注册了?null
请给我一些指示,因为我对下一步感到非常困惑。
