【笔记】使用Elasticsearch发送一个很坑的错

Unsatisfied dependency expressed through field 'esManagerMapper';  nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'esManagerMapper': Invocation of init method failed;  nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.data.elasticsearch.repository.support. NumberKeyedRepository]: Constructor threw exception;  nested exception is java.lang.IllegalArgumentException: mapper [categoryName] of different type, current_type [text], merged_type [keyword]

我一开始以为是bean 的问题，后面把Elasticsearch中的索引删了再运行就正常了。
