使用Jquery-easyUI的datagrid从后台加载数据不成功的解决办法 / 憋错料

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

        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

public interface PersonInfoDAO {

    int insert(PersonInfoDTO personInfoDTO);

    List<PersonInfoDTO> selectByPerson(PersonInfoDTO personInfoDTO);

    PersonInfoDTO checkAccNum(String accNum);

}

package com.zsrt.emp.dao;

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
