import org.springframework.data.domain.Pageable; import org.springframework.data.elasticsearch.annotations.Query; import org.springframework.data.elasticsearch.repository.ElasticsearchCrudRepository; import org.springframework.stereotype.Repository;

@Repository public interface FeedbackRepository extends ElasticsearchCrudRepository<Feedback, Long> {

@Query("{\"bool\" : {\"must\" : {\"term\" : {\"content\" : \"?0\"}}}}")
List<Feedback> findByContent(String content, Pageable pageable);

List<Feedback> findByContentAndIpLike(String content, String ip);

/** Find by Feedback.user, this can't get the correct result. */
List<Feedback> findByUser(User user);

/** Find by Feedback.user.id */
List<Feedback> findByUserId(Long userId);

}

And custom date fomat, ip seaching, and ignore fields save to _source.

import org.springframework.data.elasticsearch.annotations.DateFormat; import org.springframework.data.elasticsearch.annotations.Document; import org.springframework.data.elasticsearch.annotations.Field; import org.springframework.data.elasticsearch.annotations.FieldIndex; import org.springframework.data.elasticsearch.annotations.FieldType;

import com.fasterxml.jackson.annotation.JsonIgnore;

@Document(indexName = "feedback1", type = "feedback") public class Feedback extends Searchable {

@Field(type = FieldType.Long)
private Long id;

@Field(
		type = FieldType.Date, 
		format = DateFormat.custom, pattern = "yyyy-MM-dd HH:mm:ss"
)
private String time;

@Field(type = FieldType.Long)
private String uid;

/** 没有使用FieldType.ip，是因为这种类型不能模糊搜索 */
/** Not using FieldType.ip，because this type can't support fuzzy search. */
@Field(index = FieldIndex.analyzed, type = FieldType.String)
private String ip;

/** 不序列化到_source */
/** Ignore this field when save to _source */
@JsonIgnore
private String area;
