bug

Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'discussPostRepository' defined in com.jsss.community.dao.elasticsearch.DiscussPostRepository defined in @EnableElasticsearchRepositories declared on ElasticsearchRepositoriesRegistrar.EnableElasticsearchRepositoriesConfiguration: Invocation of init method failed; nested exception is org.springframework.data.mapping.MappingException: Property DiscussPost.createTime is annotated with FieldType.Date but has no DateFormat defined
  at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.initializeBean(AbstractAutowireCapableBeanFactory.java:1794)
