2. Java代码

代码结构如下

com.example.demo.model.SipBean
com.example.demo.dao.SipRepository
com.example.demo.service.SipService
com.example.demo.service.impl.SipServiceImpl
com.example.demo.action.SipController
com.example.demo.DemoApplication

2.1. model包

自己定义的类

package com.example.demo.model;

import java.util.Date;

import org.springframework.data.annotation.Id;
import org.springframework.data.elasticsearch.annotations.Document;

@Document(indexName = "t_sip", type = "sip", shards = 1, replicas = 0, refreshInterval = "-1")  
public class SipBean {
    @Id
    private Integer id;
    private Integer actiontype;
    private Integer areaid;
    private String assetid;
    private Integer bandwidth;
    private String c1url;
    private String destination;
    private String dstip;
    private Integer dstport;
    private String frequency;
    private String groupcode;
    private String programno;
    private String purchasetoken;
    private String qamname;
    private String requestheader;
    private String responseheader;
    private Integer responsetime;
    private Integer scale;
    private String sessionid;
    private String sn;
    private String source;
    private String srcip;
    private Integer srcport;
    private Integer statuscode;
    private String statusmsg;
    private Date time;
    private String url;


    public SipBean() {
    }

    public SipBean(Integer id, Integer actiontype, Integer areaid, String assetid, Integer bandwidth, String c1url,
            String destination, String dstip, Integer dstport, String frequency, String groupcode, String programno,
            String purchasetoken, String qamname, String requestheader, String responseheader, Integer responsetime,
            Integer scale, String sessionid, String sn, String source, String srcip, Integer srcport,
            Integer statuscode, String statusmsg, Date time, String url) {
        this.id = id;
        this.actiontype = actiontype;
        this.areaid = areaid;
        this.assetid = assetid;
        this.bandwidth = bandwidth;
        this.c1url = c1url;
        this.destination = destination;
        this.dstip = dstip;
        this.dstport = dstport;
        this.frequency = frequency;
        this.groupcode = groupcode;
        this.programno = programno;
        this.purchasetoken = purchasetoken;
        this.qamname = qamname;
        this.requestheader = requestheader;
        this.responseheader = responseheader;
        this.responsetime = responsetime;
        this.scale = scale;
        this.sessionid = sessionid;
        this.sn = sn;
        this.source = source;
        this.srcip = srcip;
        this.srcport = srcport;
        this.statuscode = statuscode;
        this.statusmsg = statusmsg;
        this.time = time;
        this.url = url;
    }

 .... getter setter ...     

}

2.2. dao层

集成了ElasticsearchRepository类，里面已经实现了基本的方法，service层可以直接调用；

package com.example.demo.dao;

import org.springframework.data.domain.Page;
import org.springframework.data.domain.Pageable;
import org.springframework.data.elasticsearch.annotations.Query;
import org.springframework.data.elasticsearch.repository.ElasticsearchRepository;

import com.example.demo.model.SipBean;

import java.util.List;

public interface SipRepository extends ElasticsearchRepository {
    /**
    *自己定义的，按照sn查询
    */  
    @Query("{\"bool\" : {\"must\" : {\"term\" : {\"sn\" : \"?0\"}}}}")
    Page findBySn(String sn, Pageable pageable);
}

2.3. service层

具体实现的业务代码

显示接口定义SipService

package com.example.demo.service;

import java.util.List;

import org.springframework.data.domain.Page;
import org.springframework.data.domain.Pageable;

import com.example.demo.model.SipBean;

public interface SipService {

    public SipBean findSip(Integer id); 

    public List<SipBean> findSipList();

    Page<SipBean> findBySn(String sn, Integer pageNumber, Integer pageSize);

    Page<SipBean> findByFuzzyQuery(String field,String value,  Integer pageNumber, Integer pageSize);

    Page<SipBean> findByMutliQuery(String start,String end, String field,String value, Integer pageNumber, Integer pageSize);

    Page<SipBean> findAll(Integer pageNumber, Integer pageSize) ;

}

下面是Service的具体实现类

package com.example.demo.service.impl;

import java.util.ArrayList;
import java.util.List;

import java.util.Optional;

import org.elasticsearch.action.search.SearchRequestBuilder;
import org.elasticsearch.index.query.BoolQueryBuilder;
import org.elasticsearch.index.query.QueryBuilder;
import org.elasticsearch.index.query.QueryBuilders;
import org.elasticsearch.search.builder.SearchSourceBuilder;
import org.elasticsearch.search.sort.SortBuilder;
import org.elasticsearch.search.sort.SortBuilders;
import org.elasticsearch.search.sort.SortOrder;
import org.joda.time.format.DateTimeFormat;
import org.joda.time.format.DateTimeFormatter;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.domain.Page;
import org.springframework.data.domain.PageRequest;
import org.springframework.data.domain.Pageable;
import org.springframework.data.domain.Sort;
import org.springframework.data.domain.Sort.Direction;
import org.springframework.scheduling.annotation.Scheduled;
import org.springframework.stereotype.Service;
import com.example.demo.dao.SipRepository;
import com.example.demo.model.SipBean;
import com.example.demo.service.SipService;
import com.google.common.collect.Lists;

@Service
public class SipServiceImpl implements SipService {

    @Autowired
    private SipRepository sipRepository;

    /**
     * 按照id查詢
     */
    @Override
    public SipBean findSip(Integer id) {
        Optional opt = sipRepository.findById(id);
        return opt.get();
    }

    /**
     *數據不多的時候，返回所有的記錄
     */
    @Override
    public List findSipList() {
        Iterable elements = sipRepository.findAll();
        List list = Lists.newArrayList(elements);
        return list;
    }

    /**
     * 分頁查詢，帶條件
     */
    @Override
    public Page findBySn(String sn, Integer pageNumber, Integer pageSize) {

        // TODO Auto-generated method stub
        QueryBuilder query = QueryBuilders.matchQuery("sn",sn);
        Pageable pageable = PageRequest.of(pageNumber, pageSize);
        return sipRepository.search(query, pageable);
    }

    /**
     * 分頁查詢
     */
    @Override
    public Page findAll(Integer pageNumber, Integer pageSize) {

        Pageable pageable = PageRequest.of(pageNumber, pageSize);
        return sipRepository.findAll(pageable);
    }

    /**
     * 分頁。模糊查詢
     */
    @Override
    public Page findByFuzzyQuery(String field,String value, Integer pageNumber, Integer pageSize) {
        QueryBuilder query = QueryBuilders.fuzzyQuery(field, value);
        Pageable pageable = PageRequest.of(pageNumber, pageSize);
        return sipRepository.search(query, pageable);
    }

    /**
     * 分頁，時間，排序查詢
     */
    @Override
    public Page findByMutliQuery(String start, String end, String field, String value, Integer pageNumber,
            Integer pageSize) {         
         DateTimeFormatter format = DateTimeFormat.forPattern("yyyy-MM-dd HH:mm:ss");
        long istart = format.parseDateTime(start).getMillis();
        long iend = format.parseDateTime(end).getMillis();
        BoolQueryBuilder query = QueryBuilders.boolQuery()
                .must(QueryBuilders.rangeQuery("time").lte(iend).gte(istart));
        if(field!=null && !"".equals(field)){
            query.must(QueryBuilders.fuzzyQuery(field, value));
        }       
        Pageable pageable = PageRequest.of(pageNumber, pageSize,Sort.by("sn"));
        //Pageable pageable2 = PageRequest.of(pageNumber, pageSize,Direction.ASC,"sn","time");

        return sipRepository.search(query, pageable);
    }
}

2.4 action层

界面调用的代码

package com.example.demo.action;

import java.util.List;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.domain.Page;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.bind.annotation.RestController;

import com.example.demo.model.SipBean;

@RestController
@RequestMapping(value = "/sip")
public class SipController {

protected final Logger logger = LoggerFactory.getLogger(this.getClass());

    @Autowired
    private com.example.demo.service.SipService sipService;

    /**
     * 按照ID查詢
     * @param id
     * @return
     */
    @RequestMapping(value = "/getSipById")
    @ResponseBody
    public Object getSipById(Integer id){
        SipBean sip =sipService.findSip(id);
        return sip;
    }


    @RequestMapping(value = "/getSipList")
    @ResponseBody
    public Object getSipList(){
        List sips =sipService.findSipList();
        return sips;
    }

    @RequestMapping(value = "/getSipByPage")
    @ResponseBody
    public Page getSipByPage(Integer pageNumber, Integer pageSize) {
        Page sips =sipService.findAll(pageNumber, pageSize);
        return sips;
    }


    @RequestMapping(value = "/getSipBySn")
    @ResponseBody
    public Page getSipBySn(String sn,Integer pageNumber, Integer pageSize) {
        Page sips =sipService.findBySn(sn, pageNumber, pageSize);
        return sips;
    }

    @RequestMapping(value = "/getSipByFuzzyQuery")
    @ResponseBody
    public Page getSipByFuzzyQuery(String field,String value,Integer pageNumber, Integer pageSize) {
        Page sips =sipService.findByFuzzyQuery(field, value, pageNumber, pageSize);
        return sips;
    }


    @RequestMapping(value = "/findByMutliQuery")
    @ResponseBody
    public Page getMutliQuery(String start,String end,String field,String value,Integer pageNumber, Integer pageSize) {
        Page sips =sipService.findByMutliQuery(start,end,field, value, pageNumber, pageSize);
        return sips;
    }    
}

2.5. SpringBoot启动代码

package com.example.demo;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.data.elasticsearch.repository.config.EnableElasticsearchRepositories;

@SpringBootApplication
@EnableElasticsearchRepositories
@ComponentScan("com.example.demo")
public class DemoApplication {  
    public static void main(String[] args) {
        SpringApplication.run(DemoApplication.class, args);     
    }   

}

3. Elasticsearch连接配置

前提是你的Elasticsearch已经配置好，可以正常使用，集群或者单个都使用，稍微改动就可以了

logging.level.com.example=DEBUG
logging.level.org.springframework.data.elasticsearch=DEBUG
spring.mvc.throw-exception-if-no-handler-found=true
spring.resources.add-mappings=false

spring.data.elasticsearch.cluster-name=es-application
spring.data.elasticsearch.cluster-nodes=172.17.5.223:9300,172.17.5.53:9300
spring.data.elasticsearch.local=false  
spring.data.elasticsearch.repositories.enabled=true 

到此，新版的es 和springboot代码已经配置完，后面就可以用写简单工具来测试。

4.测试工具

我用的工具是postman,需要的同学可以导官网上下载，后台开发必备利器！
