場景

Junit中運行單元測試時提示：

Method XXX should have no parameters

如圖：

代碼如下：

package com.ws.test.common;import com.baomidou.mybatisplus.core.conditions.query.QueryWrapper; import com.baomidou.mybatisplus.extension.service.impl.ServiceImpl; import com.ws.sys.entity.SysEnterpriseOrg; import com.ws.sys.mapper.SysEnterpriseOrgMapper; import org.junit.Test;import java.util.ArrayList; import java.util.List;public class diguiTest extends ServiceImpl<SysEnterpriseOrgMapper, SysEnterpriseOrg> {List<Long> result = new ArrayList<Long>();@Testpublic void test(){List<Long> canshu = new ArrayList<Long>();canshu.add(1l);selectChild(canshu);for (Long s :result) {System.out.print(s);}}@Testpublic void selectChild(List<Long> ids){List<Long> temp= new ArrayList<Long>();List<SysEnterpriseOrg> sysEnterpriseOrgList = new ArrayList<SysEnterpriseOrg>();for (Long id :ids) {//查詢子級架構QueryWrapper<SysEnterpriseOrg> sysEnterpriseOrgChildQueryWrapper = new QueryWrapper<SysEnterpriseOrg>();sysEnterpriseOrgChildQueryWrapper.eq("pid",id);sysEnterpriseOrgList= this.baseMapper.selectList(sysEnterpriseOrgChildQueryWrapper);if(sysEnterpriseOrgList!=null&&sysEnterpriseOrgList.size()!=0){for (SysEnterpriseOrg s:sysEnterpriseOrgList) {temp.add(s.getId());result.add(s.getId());}selectChild(temp);}}} }

解決

Junit的單元測試@Test不能有返回值和參數。

所以將下面遞歸函數的@Test去掉即可。

package com.ws.test.common;import com.baomidou.mybatisplus.core.conditions.query.QueryWrapper; import com.baomidou.mybatisplus.extension.service.impl.ServiceImpl; import com.ws.sys.entity.SysEnterpriseOrg; import com.ws.sys.mapper.SysEnterpriseOrgMapper; import org.junit.Test;import java.util.ArrayList; import java.util.List;public class diguiTest extends ServiceImpl<SysEnterpriseOrgMapper, SysEnterpriseOrg> {List<Long> result = new ArrayList<Long>();@Testpublic void test(){List<Long> canshu = new ArrayList<Long>();canshu.add(1l);selectChild(canshu);for (Long s :result) {System.out.print(s);}}public void selectChild(List<Long> ids){List<Long> temp= new ArrayList<Long>();List<SysEnterpriseOrg> sysEnterpriseOrgList = new ArrayList<SysEnterpriseOrg>();for (Long id :ids) {//查詢子級架構QueryWrapper<SysEnterpriseOrg> sysEnterpriseOrgChildQueryWrapper = new QueryWrapper<SysEnterpriseOrg>();sysEnterpriseOrgChildQueryWrapper.eq("pid",id);sysEnterpriseOrgList= this.baseMapper.selectList(sysEnterpriseOrgChildQueryWrapper);if(sysEnterpriseOrgList!=null&&sysEnterpriseOrgList.size()!=0){for (SysEnterpriseOrg s:sysEnterpriseOrgList) {temp.add(s.getId());result.add(s.getId());}selectChild(temp);}}} }
