Spring Data Couchbase和Spring Data MongoDB同時使用

Question

我想同時使用Spring Data Couchbase和Spring Data MongoDB。 但它有錯誤發生，它們都定義了自定義轉換的豆。 那麼，怎麼處理呢？

這是堆棧跟蹤

我找到辦法：

只需重寫和重新命名的bean。

這是Couchbase配置：

public class CouchbaseConfig extends AbstractCouchbaseConfiguration { 
    @Override 
    @Bean(name = "couchbaseConversions") 
    public CustomConversions customConversions() { 
     return new CustomConversions(Collections.emptyList()); 
    } 
} 

，這是MongoDB的配置：

public class MongoDBConfig extends AbstractMongoConfiguration { 
    @Override 
    @Bean(name = "mongoDBConversions") 
    public CustomConversions customConversions() { 
     return new CustomConversions(Collections.emptyList()); 
    } 
} 

感謝。
