java - 尝试从类 org.springframework.data.mapping.PropertyReferenceException 访问类 org.springframework.beans.PropertyMatches

Question

我尝试使用 org.springframework.data.mongodb.core.MongoOperations 从 mongo 集合中查询记录。我在 CompanyTemplRepoImpl 类中定义了一个类似“List find(List Industries, Pageable pageable)”的方法。运行错误信息如下所示。当我将方法名称更改为“findByIndustry”时，错误消息消失了，但结果总是得到一个列表“[]”。我已经在“公共(public)接口(interface)CompanyRepo扩展MongoRepository，CompanyTemplRepo”中定义了一个名为“findByIndustry”的方法。

1.CompanyTemplRepo接口(interface):

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类

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接口(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;

        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) {

                        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;
        }
    }

}

Spring Data 上的 org.springframework.data.mapping.PropertyReferenceException.detectPotentialMatches 使用的 PropertyMatches.forField 使用 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
