springboot2.2+整合elasticsearch 7.x

springboot整合elasticsearch7.x

1.导入依赖2.进行环境配置

1.application.properties2.config 配置3 继承ElasticsearchRepository 成springBean4.实体类以及数据库操作

4.1 实体映射4.2 dao 和mapper4.3 数据库脚本 3.api调用

1.导入依赖

                            lombok

2.进行环境配置 1.application.properties

# ServerProperties
server.port=8080
server.servlet.context-path=/es

# ThymeleafProperties
spring.thymeleaf.cache=false

# DataSourceProperties
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
spring.datasource.url=jdbc:mysql://localhost:3306/es?characterEncoding=utf-8&useSSL=false&serverTimezone=Hongkong
spring.datasource.username=root
spring.datasource.password=root
spring.datasource.type=com.zaxxer.hikari.HikariDataSource
spring.datasource.hikari.maximum-pool-size=15
spring.datasource.hikari.minimum-idle=5
spring.datasource.hikari.idle-timeout=30000

# MybatisProperties
mybatis.mapper-locations=classpath:mapper
@Repository
public interface DiscussPostRepository extends ElasticsearchRepository {

}

4.实体类以及数据库操作 4.1 实体映射

package com.boot.es.pojo;

import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;
import org.springframework.data.annotation.Id;
import org.springframework.data.elasticsearch.annotations.document;
import org.springframework.data.elasticsearch.annotations.Field;
import org.springframework.data.elasticsearch.annotations.FieldType;

import java.util.Date;

@Data
@AllArgsConstructor
@NoArgsConstructor
@document(indexName = "elastic-test",  shards = 6, replicas = 3)
public class DiscussPost {

    @Id
    private int id;

    @Field(type = FieldType.Integer)
    private int userId;

    
    @Field(type = FieldType.Text, analyzer = "ik_max_word", searchAnalyzer = "ik_smart")
    private String title;

    @Field(type = FieldType.Text, analyzer = "ik_max_word", searchAnalyzer = "ik_smart")
    private String content;

    @Field(type = FieldType.Integer)
    private int type;

    @Field(type = FieldType.Integer)
    private int status;

    @Field(type = FieldType.Date)
    private Date createTime;

    @Field(type = FieldType.Integer)
    private int commentCount;

    @Field(type = FieldType.Double)
    private double score;
}

4.2 dao 和mapper

package com.nowcoder.community.dao;

import com.nowcoder.community.entity.DiscussPost;
import org.apache.ibatis.annotations.Mapper;
import org.apache.ibatis.annotations.Param;
import org.springframework.stereotype.Repository;

import java.util.List;


@Mapper
@Repository
public interface DiscussPostMapper {

    List selectDiscussPosts(int userId, int offset, int limit);

    // @Param注解用于给参数取别名,
    // 如果只有一个参数,并且在里使用,则必须加别名.
    int selectDiscussPostRows(@Param("userId") int userId);

    int insertDiscussPost(DiscussPost discussPost);

    DiscussPost selectDiscussPostById(int id);

    int updateCommentCount(int id, int commentCount);
}

mapper.xml





    
        id, user_id, title, content, type, status, create_time, comment_count, score
    

    
        user_id, title, content, type, status, create_time, comment_count, score
    

    
        select count(id)
        from discuss_post
        where status != 2
        
            and user_id = #{userId}
        
    

    
        insert into discuss_post()
        values(#{userId},#{title},#{content},#{type},#{status},#{createTime},#{commentCount},#{score})
