mongotemplate 简单使用

　　怎么说呢，工做须要，不可能给你慢慢学的时间，一切以先解决当前jira为前提， mondb 安装不说了网上一搜就有，推荐图形管理界面 robo3t 比较直观

 

1.多条件查询这个比较简单

　　有两种方法

　　1Criteria.where("company_code").is(corpCode).and("emp_id").in(empIdArray)这种写法

　　2Criteria criatira = new Criteria();

   criatira.andOperator(Criteria.where( "userName" ).is( "admin" ), Criteria.where( "password" ).is( "f818fa8cf51ca364f367f0046bd014ff" ));

　　推荐第一中简单明了

 

2，删除多条数据

　　

Query query = Query.query(Criteria.where("company_code").is(corpCode).and("emp_id").in(empIdArray));
//删除department_code
Update updateDepartmentCode = new Update();
updateDepartmentCode.pullAll("department_code", deptArray.toArray());
mongoTemplate.updateMulti(query, updateDepartmentCode, Constants.MONGOBD_EMPLOYEE_COLLECTION_BEGIN + corpCode.toUpperCase());

//查询并删除department
Update updateDepartment = new Update();
List<JSONObject> deptList = esDepartmentService.checkAndFindDepartment(corpCode, deptArray);
updateDepartment.pullAll("department", deptList.toArray());
mongoTemplate.updateMulti(query, updateDepartment, Constants.MONGOBD_EMPLOYEE_COLLECTION_BEGIN + corpCode.toUpperCase());

 

3增长多条数据

Query query = Query.query(Criteria.where("company_code").is(corpCode).and("emp_id").in(empIdArray));
//删除department_code
Update updateDepartmentCode = new Update();
updateDepartmentCode.pullAll("department_code", deptArray.toArray());
mongoTemplate.updateMulti(query, updateDepartmentCode, Constants.MONGOBD_EMPLOYEE_COLLECTION_BEGIN + corpCode.toUpperCase());

//查询并删除department
Update updateDepartment = new Update();
List<JSONObject> deptList = esDepartmentService.checkAndFindDepartment(corpCode, deptArray);
updateDepartment.pullAll("department", deptList.toArray());
mongoTemplate.updateMulti(query, updateDepartment, Constants.MONGOBD_EMPLOYEE_COLLECTION_BEGIN + corpCode.toUpperCase());

 

4同一个update对象不能屡次使用，后面的条件会覆盖掉前面的数据。
