8、2 es数据库的使用

com.bw; import org.springframework.beans.factory.InitializingBean; import org.springframework.stereotype.Component; //import lombok.extern.slf4j.Slf4j; //@Slf4j @Component public class ElasticSearchConfiguration implements InitializingBean { private static final org.slf4j.Logger log = org.slf4j.LoggerFactory.getLogger(ElasticSearchConfiguration.class); static { System.setProperty("es.set.netty.runtime.available.processors", "false"); } @Override public void afterPropertiesSet() throws Exception { log.info("*****************es_config*************************"); log.info("es.set.netty.runtime.available.processors:{}", System.getProperty("es.set.netty.runtime.available.processors")); log.info("***************************************************"); } }

2、就2个注解，2个属性

package com.bw.entity;

import org.springframework.data.annotation.Id;
import org.springframework.data.elasticsearch.annotations.Document;
@Document(indexName = "week",type = "week02")
public class Student {
    @Id
    private String sid;
    private String sname;
    private String pwd;
    public String getSid() {
        return sid;
    }
    public void setSid(String sid) {
        this.sid = sid;
    }
    public String getSname() {
        return sname;
    }
    public void setSname(String sname) {
        this.sname = sname;
    }
    public String getPwd() {
        return pwd;
    }
    public void setPwd(String pwd) {
        this.pwd = pwd;
    }
    public Student() {
        super();
        // TODO Auto-generated constructor stub
    }
    public Student(String sid, String sname, String pwd) {
        this.sid = sid;
        this.sname = sname;
        this.pwd = pwd;
    }
    @Override
    public String toString() {
        return "Student [sid=" + sid + ", sname=" + sname + ", pwd=" + pwd + "]";
    }
    

}

配置

server:
  port: 9007
  
spring:
  application:
    name: tensquare‐search #指定服务名
  data:
    elasticsearch:
      cluster-nodes: 127.0.0.1:9300

 

依赖

<!--   es的依赖-->
