Question

我想同时使用Spring Data Couchbase和Spring Data MongoDB。但是它发生了错误，它们都定义了hava bean customConversions 。那么，怎么处理呢？

这是stacktrace

我找到了方法：

只需覆盖并重命名bean。

这是Couchbase配置：

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

这是MongoDB配置：

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

感谢。
