我尝试使用org.springframework.data.mongodb.core.MongoOperations查询来自mongo集合的记录。我定义了一个这样的方法＆＃34;列表查找（列出行业，可分页可分页）＆＃34;在CompanyTemplRepoImpl类中。运行错误消息如下所示。当我将方法名称更改为＆＃34; findByIndustry＆＃34;时，错误消息消失了，但我总是得到一个列表＆＃34; []＆＃34;作为结果。 我已经定义了一个名为＆＃34; findByIndustry＆＃34; in＆＃34;公共接口CompanyRepo扩展了MongoRepository，CompanyTemplRepo＆＃34;。
1.CompanyTemplRepo界面：
package com.chaoke.smart.repo;
import java.util.List;
import org.springframework.data.domain.Pageable;
import com.chaoke.smart.jpa.data.IcmsCompany;
public interface CompanyTemplRepo {
List<IcmsCompany> find(List<String> industries, Pageable pageable);
}
2.impl class
package com.chaoke.smart.repo.impl;
import static org.springframework.data.mongodb.core.query.Criteria.where;
import static org.springframework.data.mongodb.core.query.Query.query;
import java.util.List;
import javax.annotation.Resource;
import org.springframework.data.domain.Pageable;
import org.springframework.data.mongodb.core.MongoOperations;
import com.chaoke.smart.jpa.data.IcmsCompany;
import com.chaoke.smart.repo.CompanyTemplRepo;
public class CompanyTemplRepoImpl implements CompanyTemplRepo {
@Resource(name = "mongoTemplate")
private MongoOperations operations;
@Override
public List<IcmsCompany> find(List<String> industries, Pageable pageable) {
System.out.println("++++++++++++++++++++++++==========================");
int pageNo = pageable.getPageNumber();
int pageSize = pageable.getPageSize();
return operations.find(query(where("industry").is("商务服务业")),
//in(industries)).skip(pageNo * pageSize).limit(pageSize),
IcmsCompany.class);
}
}
3.CompanyService Interface：
public interface CompanyService {
public List<CompanyListResult> getConcernCompanyListPageable(String account, String industry, int pn, int ps);
public IcmsCompany getConcernCompanyDetail(String companyId, String account);
}
4
@Repository
public interface CompanyRepo extends MongoRepository<IcmsCompany, String>, CompanyTemplRepo {
List<IcmsCompany> findByIndustry(String industry, Pageable pageable);
IcmsCompany findOneByCompanyId(Integer companyId);
}
5.service.impl
package com.chaoke.smart.service.impl;
import java.util.ArrayList;
import java.util.List;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.domain.PageRequest;
import org.springframework.data.domain.Pageable;
import org.springframework.stereotype.Service;
import com.chaoke.smart.jpa.data.IcmsCompany;
import com.chaoke.smart.jpa.data.IcmsFollowCompanyList;
import com.chaoke.smart.model.CompanyListResult;
import com.chaoke.smart.repo.CompanyRepo;
import com.chaoke.smart.repo.FollowCompanyListRepo;
import com.chaoke.smart.service.CompanyService;
import lombok.Data;
@Data
@Service("companyService")
public class CompanyServiceImpl implements CompanyService {
@Autowired
FollowCompanyListRepo followCompanyListRepo;
@Autowired
CompanyRepo companyRepo;
@Override
public List<CompanyListResult> getConcernCompanyListPageable(String account, String industry, int pn, int ps) {
List<CompanyListResult> resultList = new ArrayList<CompanyListResult>();
try {
Pageable pageable = new PageRequest(pn, ps);
// 没有industry参数时，先查询客户关注的industry，然后根据industry查询company表。
if (industry == null || "".equals(industry)) {
List<IcmsFollowCompanyList> list1 = followCompanyListRepo.findByAcctId(Integer.valueOf(account));
if (list1 != null && list1.size() > 0) {
ArrayList<String> indusList = new ArrayList<String>();
for (IcmsFollowCompanyList icmsFollowCompanyList : list1) {
indusList.add(icmsFollowCompanyList.getIndustry());
}
List<IcmsCompany> compList = companyRepo.find(indusList, pageable);
for (IcmsCompany icmsCompany : compList) {
CompanyListResult companyListResult = new CompanyListResult();
companyListResult.setCompanyId(icmsCompany.getCompanyId());
companyListResult.setCompanyName(icmsCompany.getCompanyName());
resultList.add(companyListResult);
}
}
// 当传递industry参数时直接按industry查询company表。
} else {
List<IcmsCompany> compList = companyRepo.findByIndustry(industry, pageable);
for (IcmsCompany icmsCompany : compList) {
CompanyListResult companyListResult = new CompanyListResult();
companyListResult.setCompanyId(icmsCompany.getCompanyId());
companyListResult.setCompanyName(icmsCompany.getCompanyName());
resultList.add(companyListResult);
}
}
return resultList;
} catch (Exception e) {
e.printStackTrace();
return resultList;
}
}
}

答案 0 :(得分：2)
org.springframework.data.mapping.PropertyReferenceException.detectPotentialMatches在spring数据上使用的PropertyMatches.forField使用了spring-beans 4.1.7版本中添加的两个方法。确保您使用的是4.1.7或更高版本
答案 1 :(得分：0)
此问题还来自org.springframwork.data.spring-data-mongodb的错误版本。我从1.8.4变为1.9.3以解决问题。
