一、BBoss-ES操作数据  ?
1、pom.xml
< dependency>
< groupId> com.bbossgroups.plugins< /groupId>
< artifactId> bboss-elasticsearch-spring-boot-starter< /artifactId>
< version> 6.0.0< /version>
< exclusions>
< exclusion>
< artifactId> slf4j-log4j12< /artifactId>
< groupId> org.slf4j< /groupId>
< /exclusion>
< /exclusions>
< /dependency>

< dependency>
< groupId> org.springframework.boot< /groupId>
< artifactId> spring-boot-starter-web< /artifactId>
< /dependency>

< dependency>
< groupId> org.elasticsearch.client< /groupId>
< artifactId> elasticsearch-rest-client< /artifactId>

< /dependency>

< dependency>
< groupId> org.elasticsearch.client< /groupId>
< artifactId> elasticsearch-rest-high-level-client< /artifactId>
< version> $elasticsearch.version< /version>
< /dependency>

2、基本配置
elasticsearch:
host: 10.1*.**.**
port: 9200
bboss:
default:
name: default
elasticPassword: elastic
elasticUser: elastic
elasticsearch:
dateFormat: yyyy.MM.dd
discoverHost: false
rest:
hostNames: 1*.**.**.**:9200
scrollBlockedWaitTimeout: 0
scrollThreadCount: 200
scrollThreadQueue: 200
showTemplate: true
sliceScrollBlockedWaitTimeout: 0
sliceScrollThreadCount: 100
sliceScrollThreadQueue: 100
timeZone: Asia/Shanghai
http:
connectionRequestTimeout: 5000
customHttpRequestRetryHandler: org.frameworkset.spi.remote.http.ConnectionResetHttpRequestRetryHandler
defaultMaxPerRoute: 200
hostnameVerifier:
keyPassword:
keystore:
maxHeaderCount: 200
maxLineLength: -1
maxTotal: 400
retryTime: 1
staleConnectionCheckEnabled: false
timeoutConnection: 5000
timeoutSocket: 5000
validateAfterInactivity: 2000
dslfile:
refreshInterval: -1

3、结构配置3.1 配置ESSTartConfigurer
import org.frameworkset.elasticsearch.boot.BBossESStarter;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Primary;

@Configuration
public class ESSTartConfigurer
@Primary
@Bean(initMethod = "start")
@ConfigurationProperties("spring.elasticsearch.bboss.default")
public BBossESStarter bbossESStarter()
return new BBossESStarter();



3.2配置EsQueryToolsConfig
import com.alibaba.fastjson.JSONObject;
import org.frameworkset.elasticsearch.boot.BBossESStarter;
import org.frameworkset.elasticsearch.client.ClientInterface;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;

@Component
public class EsQueryToolsConfig

@Autowired
private BBossESStarter bbossESStarterDefault;

/**
* 用sql查询
* @param sql
* @return
*/
public String queryForSQL(String sql)
ClientInterface clientUtil = bbossESStarterDefault.getRestClient();
JSONObject jsonObject = new JSONObject();
jsonObject.put("sql",sql);
String rtnJson = clientUtil.executeHttp("/_sql/", jsonObject.toJSONString(), ClientInterface.HTTP_POST);
return rtnJson;


/**
* 用原生的 es的dsl查询
* @param indexName
* @param dsl
* @return
*/
public String queryForDSL(String indexName,String dsl)
ClientInterface clientUtil = bbossESStarterDefault.getRestClient();
String rtnJson = clientUtil.executeHttp("/" + indexName + "/_search", dsl, ClientInterface.HTTP_POST);
return rtnJson;



4、CRUD4.1 - C
在业务接口 **impl 中，实现基本业务逻辑。
代码块代表当前业务逻辑，具体问题具体分析。
@Service
public class TeacherResourceServiceImpl implements TeacherResourceService

@Autowired
private TeacherResourceDao teacherResourceDao;

@Autowired
private ElasticsearchRestTemplate elasticsearchRestTemplate;

@Override
public PageInfo< TeacherResourceVO> findTeacherResourceFromES(T*****TO t***TO) throwsException
List t*******OsList = new ArrayList();
PageInfo< T******O> teacherResPages = new PageInfo< > ();
if (elasticsearchRestTemplate.indexExists("s*******n"))
//聚合获取学校id-教师id的相关信息
String teacherResJson = teacherResourceDao.findTeacherResourceList(t*******TO) ;
JSONObject buildTeacherObj = JSONObject.parseObject(teacherResJson);
JSONArray buildTeacherArr = buildTeacherObj.getJSONObject("aggregations").getJSONObject("b*******_id").getJSONArray("buckets");
for (int i = 0; i < buildTeacherArr.size(); i++)
TeacherResourceVO teacherResourceVO = new TeacherResourceVO();
JSONObject teacherObj = buildTeacherArr.getJSONObject(i);
if (null != teacherObj)
String teacherId = teacherObj.getString("key");
String teacherNameJson = teacherResourceDao.getUserNameFromES(teacherId);
JSONObject teacherNameObj = JSONObject.parseObject(teacherNameJson);
String teacherName = teacherNameObj.getJSONObject("hits").getJSONArray("hits").getJSONObject(0).getJSONObject("_source").getString("user_name");
JSONObject schoolNameObj = JSONObject.parseObject(schoolNameJson);
String schoolName = schoolNameObj.getJSONObject("hits").getJSONArray("hits").getJSONObject(0).getJSONObject("_source").getString("organization_name");
teacherResourceVO.setTeacherId(teacherId);
teacherResourceVO.setTeacherName(teacherName);
teacherResourceVO.setRecourceAccount(Integer.parseInt(teacherResCount));
teacherResourceVOsList.add(teacherResourceVO);


Integer totalNum = teacherResourceVOsList.size();
int pageNum =teacherResourceDTO.getPageNum();
int pageSize = teacherResourceDTO.getPageSize();
Integer totalPage = 0;
if (totalNum > 0)
totalPage = totalNum % pageSize == 0 ? totalNum / pageSize : totalNum / pageSize + 1;

if (pageNum > totalPage)
pageNum = totalPage;

int startPoint = (pageNum - 1) * pageSize;
int endPoint = startPoint + pageSize;
if (totalNum < = endPoint)
endPoint = totalNum;

List PageList = new ArrayList();
PageList =t******OsList.subList(startPoint, endPoint);
teacherResPages.setPageNum(t*****TO.getPageNum());
teacherResPages.setPageSize(t*******O.getPageSize());
teacherResPages.setTotal(t******sList.size());
teacherResPages.setPages(totalPage );
teacherResPages.setList(PageList);
return teacherResPages;

return teacherResPages;


在dao层 引入文件【见上】：
@Autowired
private EsQueryToolsConfig esQueryToolsConfig;

/***
* 获取学校教师资源数量
* @param teacherResourceDTO
* @return
* @throws Exception
*/
public String findTeacherResourceList(T*******O *****O) throwsException
SimpleDateFormat simpleDateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
//基础sql
String select_sql = "select base_user_id , count(*) as teacherResCountfroms*******n ";
String where_sql = "where1=1 ";
String groupBy_sql = "group by base_user_id ";
String order_sql = " order by teacherResCount desclimit 10";
if(StringUtils.isNotBlank(t********O.getSchoolId()))
where_sql = where_sql.concat(" and b******_id = " + t*******O.getSchoolId() + " ");

if (StringUtils.isNotBlank(te*****O.getBeginDate()))
longbeginTime = simpleDateFormat.parse(t*****O.getBeginDate() + LoginConstant.START_TIME).getTime();
where_sql = where_sql.concat( " and create_time > = " + beginTime + " ");

if (StringUtils.isNotBlank(t******O.getEndDate()))
longendTime = simpleDateFormat.parse(te********O.getEndDate() + LoginConstant.END_TIME).getTime();
where_sql = where_sql.concat( " and create_time < " + endTime + " ");

String sql = select_sql + where_sql + groupBy_sql;
String retJson = this.esQueryToolsConfig.queryForSQL( sql );
System.out.println(sql);
return retJson;

二、抽ES数据存到List数组
//自定义 学科名称数组
ArrayList arraySubList = new ArrayList();
ArrayList arraySubIdList = new ArrayList();
if (elasticsearchRestTemplate.indexExists("s*******************b"))
SearchQuery searchQuery = new NativeSearchQueryBuilder()
.withIndices("s************b")
.withTypes("_***************")
.withQuery(boolQuery)
.build();
//统计学生的发布课程信息
List< St***************O> s*************Os = elasticsearchRestTemplate.queryForList(searchQuery, S*************O.class);
//根据学生发布课程编号获取学段，学科基本信息
for (int i = 0; i < stuIssueD**********s.size(); i++)
String strCourseId = stu************s.get(i).getCourse_base_id();
//课程统计
BoolQueryBuilder queryCourseInfo = QueryBuilders.boolQuery();
queryCourseInfo.must(QueryBuilders.termQuery("co******id", strCourseId));
SearchQuery queryCourse = new NativeSearchQueryBuilder()
.withIndices("s****************o")
.withTypes("_d************************")
.withQuery(queryCourseInfo)
.build();
List< Co******O> co*************List = elasticsearchRestTemplate.queryForList(queryCourse, C***********O.class);
for (int j = 0; j < co**********ist.size(); j++)
BoolQueryBuilder querySubInfo = QueryBuilders.boolQuery();
//学段信息
if (StringUtils.isNotBlank(subjectId))
querySubInfo.must(QueryBuilders.termQuery("s******de", subjectId));
else
querySubInfo.must(QueryBuilders.termQuery("s***********de", courseVOFromESList.get(j).getBusiness_subject_id()));

//学科信息
if (StringUtils.isNotBlank(stageId))
querySubInfo.must(QueryBuilders.termQuery("s******de", stageId));
else
querySubInfo.must(QueryBuilders.termQuery("s*******de", courseVOFromESList.get(j).getBu*******_id()));

SearchQuery querySubjectInfo = new NativeSearchQueryBuilder()
.withIndices("st*********t")
.withTypes("_***********c")
.withQuery(querySubInfo)
.build();
List< Su***********O> subList = elasticsearchRestTemplate.queryForList(querySubjectInfo, Su*********O.class);
//动态添加 - list数组
//动态添加 - list数组
arraySubList.add(subList.get(0).getSubject_name());
arraySubIdList.add(subList.get(0).getSubject_code());


List< St**********O> s**************List = homeworkService.getQuestionAndknowledgeTotal(s****************O);
for (int i = 0; i < st************List.size(); i++)
//学生学习的课程数量
st**************List.get(i).setResourceAccount(s************s.size());
stud**************List.get(i).setSubjectId(subjectId);
//学科名称
subList.stream().map(S*******::getSubject_name).collect(Collectors.toList());
//studentSubResourceVOList.get(i).setSubjectName(subName.toString());


return studentSubResourceVOs;
