MongoConfig配置文件存在错误

难难难，道德玄，
不对知音不可谈，
对了知音谈几句，
不对知音枉废舌尖！

我用的是mongdb的数据库，而且是集群配置的，在启动项目会时不时的报出以下错误，让在配置文件中添加spring.main.allow-bean-definition-overriding=true 的配置，但是我在用时加上以上配置还是报错，然后我就修改MongConfig配置文件的名字，有时候就能用了。

今天我改了好多次名字，项目还是启动不了，换了个服务器还是报错，以前都是凑合着解决这个问题，但是一直没有找到原因，今天终于凑合不了了，望各位大佬们给提点一下子，万分感谢！

Description:

The bean 'mongoMappingContext', defined in class path resource [cn/sciencedb/config/MongodbConfig.class], could not be registered. A bean with that name has already been defined in null and overriding is disabled.

Action:

Consider renaming one of the beans or enabling overriding by setting spring.main.allow-bean-definition-overriding=true

MongoConfig配置如下：

package cn.sciencedb.config;

import com.mongodb.MongoClient;
import com.mongodb.MongoClientURI;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.mongodb.MongoDbFactory;
import org.springframework.data.mongodb.MongoTransactionManager;
import org.springframework.data.mongodb.config.AbstractMongoConfiguration;
import org.springframework.data.mongodb.core.convert.MongoConverter;
import org.springframework.data.mongodb.gridfs.GridFsTemplate;

@Configuration
public class MongodbConfig extends AbstractMongoConfiguration{

    @Value("${spring.data.mongodb.uri}")
    private String mongoUri;
    @Autowired
    private MongoConverter mongoConverter;

    @Bean
    GridFsTemplate gridFsTemplate(MongoDbFactory dbFactory) {
        return new GridFsTemplate(dbFactory, mongoConverter);
    }

    @Bean
    MongoTransactionManager transactionManager(MongoDbFactory dbFactory) {
        return new MongoTransactionManager(dbFactory);
    }

    @Override
    @Bean
    public MongoClient mongoClient() {
        MongoClientURI uri = new MongoClientURI(mongoUri);
        return new MongoClient(uri);
    }

    @Override
    protected String getDatabaseName() {
        //String dataBase = mongoUri.substring(mongoUri.lastIndexOf("/") + 1);
        return "sdb";
    }
}
