篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了使用Jquery-easyUI的datagrid从后台加载数据不成功的解决办法相关的知识,希望对你有一定的参考价值。
最近在用easyUI做一个注册页面总是出现从后台数加载不成功的问题,后来在一个师兄的指导下通过debug模式终于发现问题并解决了,以下记录我解决这一问题的过程。开发环境:jdk1.7,工具:eclipse,框架:spring-mvc

以下为实体类代码:
package com.zsrt.entity; import javax.persistence.Table; @Table(name="person_info") public class PersonInfoDTO { private String id; private String name; private String sex; private String province;//省 private String city;//市 private String phone; private String accNum; private String email; public String getId() { return id; } public void setId(String id) { this.id = id; } public String getName() { return name; } public void setName(String name) { this.name = name; } public String getSex() { return sex; } public void setSex(String sex) { this.sex = sex; } public String getProvince() { return province; } public void setProvince(String province) { this.province = province; } public String getCity() { return city; } public void setCity(String city) { this.city = city; } public String getPhone() { return phone; } public void setPhone(String phone) { this.phone = phone; } public String getAccNum() { return accNum; } public void setAccNum(String accNum) { this.accNum = accNum; } public String getEmail() { return email; } public void setEmail(String email) { this.email = email; } @Override public String toString() { return "PersonInfoDTO [id=" + id + ", name=" + name + ", sex=" + sex + ", province=" + province + ", city=" + city + ", phone=" + phone + ", accNum=" + accNum + ", email=" + email + "]"; }
}
package com.zsrt.entity; import java.util.Date; import org.hibernate.validator.constraints.NotEmpty; import org.springframework.format.annotation.DateTimeFormat; public class Emp { public Date getBirthday() { return birthday; } public void setBirthday(Date birthday) { this.birthday = birthday; } private Integer empid; private String accNum; private String accPass; private String empName; private String empPhone; private Date birthday; private Integer deptid ; private Integer roleid; private String email; public Integer getEmpid() { return empid; } public void setEmpid(Integer empid) { this.empid = empid; } public String getAccNum() { return accNum; } public void setAccNum(String accNum) { this.accNum = accNum; } public String getAccPass() { return accPass; } public void setAccPass(String accPass) { this.accPass = accPass; } public String getEmpName() { return empName; } public void setEmpName(String empName) { this.empName = empName; } public String getEmpPhone() { return empPhone; } public void setEmpPhone(String empPhone) { this.empPhone = empPhone; } public Integer getDeptid() { return deptid; } public void setDeptid(Integer deptid) { this.deptid = deptid; } public Integer getRoleid() { return roleid; } public void setRoleid(Integer roleid) { this.roleid = roleid; } public String getEmail() { return email; } public void setEmail(String email) { this.email = email; } @Override public String toString() { return "Emp [empid=" + empid + ", accNum=" + accNum + ", accPass=" + accPass + ", empName=" + empName + ", empPhone=" + empPhone + ", birthday=" + birthday + ", deptid=" + deptid + ", roleid=" + roleid + ", email=" + email + "]"; } }
Emp的扩展类
package com.zsrt.entity; public class EmpCustom extends Emp{ private int nextRoleid; private String roleName; public int getNextRoleid() { return nextRoleid; } public void setNextRoleid(int nextRoleid) { this.nextRoleid = nextRoleid; } public String getRoleName() { return roleName; } public void setRoleName(String roleName) { this.roleName = roleName; } }
package com.zsrt.entity; import javax.persistence.Table; public class DictDTO { private String id; private String itemCode; private String itemName; private String typeCode; private String status; private String parentCode; public String getId() { return id; } public void setId(String id) { this.id = id; } public String getItemCode() { return itemCode; } public void setItemCode(String itemCode) { this.itemCode = itemCode; } public String getItemName() { return itemName; } public void setItemName(String itemName) { this.itemName = itemName; } public String getTypeCode() { return typeCode; } public void setTypeCode(String typeCode) { this.typeCode = typeCode; } public String getStatus() { return status; } public void setStatus(String status) { this.status = status; } public String getParentCode() { return parentCode; } public void setParentCode(String parentCode) { this.parentCode = parentCode; } }
personInfoDTO在数据库中对应的表,表明为person_info
Emp类在数据库中对应的表,表命名为oa_emp
dict字典表
插入数据后
由于数据库内容太多,而sql语句没有及时保存,所以就不一一截图了,插入数据的原理是属于一个省的城市其parentCode为该省所对应的itemCode
DAO层代码
package com.zsrt.emp.dao; import java.util.List; import com.zsrt.entity.PersonInfoDTO; /** * personinfoDAO * @author leixin * @Date 2017年5月22日 * @version 1.0 */ public interface PersonInfoDAO { int insert(PersonInfoDTO personInfoDTO); List<PersonInfoDTO> selectByPerson(PersonInfoDTO personInfoDTO); PersonInfoDTO checkAccNum(String accNum); }
package com.zsrt.emp.dao; import java.util.List; import com.zsrt.entity.DictDTO; /** * 字典表DAO * @author leixin * @Date 2017年5月22日 * @version 1.0 */ public interface DictDAO { List<DictDTO> selectByDictDTO(DictDTO dictDTO); String queryItemName(String itemCode); }
Mapper层代XML码

Service层代码
package com.zsrt.emp.service; import java.util.List; import com.zsrt.entity.DictDTO; public interface DictService { List<DictDTO> selectByDictDTO(DictDTO dictDTO); String queryItemName(String itemCode); }
package com.zsrt.emp.service; import java.util.List; import java.util.Map; import com.zsrt.entity.PersonInfoDTO; public interface PersonInfoService { Map<String, Object> insert(PersonInfoDTO personInfoDTO); List<PersonInfoDTO> selectByPerson(PersonInfoDTO personInfoDTO); PersonInfoDTO checkAccNum(String accNum); }
对应的服务层实现类
package com.zsrt.emp.service.impl; import java.util.List; import javax.annotation.Resource; import org.springframework.stereotype.Service; import com.zsrt.emp.dao.DictDAO; import com.zsrt.emp.service.DictService; import com.zsrt.entity.DictDTO; @Service public class DictServiceImpl implements DictService{ @Resource private DictDAO dictDAO; @Override public List<DictDTO> selectByDictDTO(DictDTO dictDTO) { return dictDAO.selectByDictDTO(dictDTO); } @Override public String queryItemName(String itemCode) { return dictDAO.queryItemName(itemCode); } }

前台注册页面代码,需求如下
前提条件:
1.在现有项目的基础上做
2.给person_info表中增加一个accNum字段,表示两张表的关联关系
3.给oa_emp表中增加邮箱字段,同时在person_info表中增加邮箱字段
1.做一个注册功能,注册采用手机号,注册成功之后跳转到个人信息页面,
并且显示个人信息,若注册失败,则页面显示错误消息 (20分)
2.个人信息显示中手机号和邮箱的两种情况:
a.person_info表中没有手机号和邮箱信息,将oa_emp中的信息取出显示在页面上 (20分)
b.person_info表中有手机号和邮箱信息,直接显示person_info表中的信息 (20分)
将性别、省市、正确显示在页面上 (20分)

注册页面效果图
跳转后页面加载数据失败效果图
通过debug调试发现前台reg.jsp页面的${personInfoMap}为空,原来是因为Model保存的Map对象 personInfoMap 只能在页面跳转一次的时候才取得到,
而下面这个save方法包含了两次跳转页面,一次是题提交表单时的url请求(url:‘${pageContext.request.contextPath}/person/save‘)
另一次为result返回给success回调函数时的跳转(self.location=contextPath+"/person/showPersonInfo")
解决办法为把 personInfoMap定义为一个全局变量,放到showPersonInfo()方法里
@RequestMapping(value="/save") @ResponseBody public Map<String, Object> save(PersonInfoDTO personInfoDTO,Model model){ personInfoDTO.setId(UUID.randomUUID().toString().replace("-", "")); String provinceCode=personInfoDTO.getProvince(); String province=dictService.queryItemName(provinceCode); personInfoDTO.setProvince(province); String cityCode=personInfoDTO.getCity(); String city=dictService.queryItemName(cityCode); personInfoDTO.setCity(city); Map<String, Object> result = personInfoService.insert(personInfoDTO); System.out.println(personInfoDTO.toString()); if(result.containsKey("success")){ Map<String,Object> personInfoMap=new HashMap<>(); if(null==personInfoDTO.getPhone()||"".equals(personInfoDTO.getPhone())){ String phone=empService.queryEmpByAccnum(personInfoDTO.getAccNum()).getEmpPhone(); personInfoDTO.setPhone(phone); } if(null==personInfoDTO.getEmail()|| "".equals(personInfoDTO.getEmail())){ String email=empService.queryEmpByAccnum(personInfoDTO.getAccNum()).getEmail(); } List<PersonInfoDTO> personList=new ArrayList<PersonInfoDTO>(); personList.add(personInfoDTO); personInfoMap.put("rows", personList); personInfoMap.put("total", 10); model.addAttribute("personInfoMap",JSON.toJSONString(personInfoMap)); System.out.println("个人信息JSON字符窜:"+JSON.toJSONString(personInfoMap)); } return result; }
修改后的PersonInfoController类的代码如下
@Controller @RequestMapping(value="/person") public class PersonInfoController { @Resource private PersonInfoService personInfoService; @Resource private DictService dictService; @Resource private EmpService empService; Map<String,Object> personInfoMap=new HashMap<>(); @RequestMapping(value="/init") public String init() { return "person"; } @RequestMapping(value="/list") @ResponseBody public Map<String, Object> list(PersonInfoDTO personInfoDTO){ Map<String, Object> result = new HashMap<>(); List<PersonInfoDTO> list = personInfoService.selectByPerson(personInfoDTO); result.put("rows", list); result.put("total", 100); System.err.println(result.toString()); return result; } @RequestMapping(value="/save") @ResponseBody public Map<String, Object> save(PersonInfoDTO personInfoDTO){ personInfoDTO.setId(UUID.randomUUID().toString().replace("-", "")); String provinceCode=personInfoDTO.getProvince(); String province=dictService.queryItemName(provinceCode); personInfoDTO.setProvince(province); String cityCode=personInfoDTO.getCity(); String city=dictService.queryItemName(cityCode); personInfoDTO.setCity(city); Map<String, Object> result = personInfoService.insert(personInfoDTO); System.out.println(personInfoDTO.toString()); if(result.containsKey("success")){ if(null==personInfoDTO.getPhone()||"".equals(personInfoDTO.getPhone())){ String phone=empService.queryEmpByAccnum(personInfoDTO.getAccNum()).getEmpPhone(); personInfoDTO.setPhone(phone); } if(null==personInfoDTO.getEmail()|| "".equals(personInfoDTO.getEmail())){ String email=empService.queryEmpByAccnum(personInfoDTO.getAccNum()).getEmail(); } List<PersonInfoDTO> personList=new ArrayList<PersonInfoDTO>(); personList.add(personInfoDTO); personInfoMap.put("rows", personList); personInfoMap.put("total", 10); } return result; } @RequestMapping(value="/checkAccNum") @ResponseBody public Object checkAccNum(String accNum){ PersonInfoDTO personInfo=personInfoService.checkAccNum(accNum); Map<String,Object> result=new HashMap<>(); System.out.println("注册帐号wei:"+accNum); if(null==personInfo){ result.put("success", "帐号可用"); } else{ System.out.println("是否重复信息"+personInfo.toString()); result.put("error", "帐号重复,不能注册"); } return result; } @RequestMapping(value="/showPersonInfo") public String showPersonInfo(Model model){ model.addAttribute("personInfoMap",JSON.toJSONString(personInfoMap)); System.out.println("个人信息JSON字符窜:"+JSON.toJSONString(personInfoMap)); return "PersonReg";
} }
修改后的效果图如下:
必须要注意的时用加载到easyui-datagrid的表格里去时后台传递数据时必须用JSON格式,后台控制层结果列表personList作为rows键的value值,回到前台再把personINfoMap转为Jquery对象${personInfoMap}才能去除加载到datagrid表格里去
以上是关于使用Jquery-easyUI的datagrid从后台加载数据不成功的解决办法的主要内容,如果未能解决你的问题,请参考以下文章
