平台后台编辑功能实现

主页面点击编辑按钮：

　　　　　　　edit:function(row){
                var dataWrap = new AjaxDataWrap("dataWrap");
                dataWrap.setData(dataTable.getRecordByRowNum(row.keyId-1));
                var data = dataWrap.toJSONData();
                var dataArr = [];
                dataArr.push(data);
                var url = $$pageContextPath + "testEnv/editappstoredetail";
                $.showModalDialog({url: url, datawrap: dataArr}, '编辑信息',
                    vm.queryList, null, "700", "500", 0);
            }

调用后台controller服务："editappstoredetail" 并返回页面

　　 @RequestMapping("/editappstoredetail")
    public String editappstoredetail(@ModelAttribute("responseData") DataCenter dc, @DataWrap AjaxDataWrap<AppRepository> dataWrap) {
        dc.setAjaxDataWrap("dataWrap", dataWrap);
        return "testenv/editappstoredetail.html";
    }

在编辑页面 点击确定按钮进行保存：并调用后台接口，保存数据到数据库

　　　　　　saveInfo: function () {
                //收集数据
                var formData = myform.collectData();
                myform.validate(function (valid) {
                    if (valid) {
                        $.request({
                            url: $$pageContextPath + 'testEnv/saveInfo',
                            data: [formData],
                            success: function (response) {
                                var code = response.getParameter("code");
                                if(code === 0){
                                    HyMessage.success([[#{operation.savedSuccessfully}]]);
                                    $.cancel();
                                }else{
                                    HyMessage.error([[#{mask.save_error}]]);
                                }
                            }
                        });
                    }
                });
            },

controller层的服务接口： “saveInfo” 

@RequestMapping("/saveInfo")
    @ResponseBody
    public DataCenter saveInfo(@ModelAttribute("responseData") DataCenter dc, 
            @DataWrap AjaxDataWrap<AppRepository> dataWrap){
        AppRepository moduleInfo = dataWrap.getData();
        try {
            repositoryService.saveInfo(moduleInfo);
            dc.setParameter("code", 0);
        } catch (Exception e) {
            dc.setParameter("code", 1);
            LogUtil.getFrameworkLoger().error("保存信息出错！", e.getMessage());
        }
        return dc;
    }

service层里处理复杂逻辑：saveInfo()

 @Override
    public AppRepository saveInfo(AppRepository moduleInfo) {
        if(moduleInfo == null){
            return null;
        }
        if(moduleInfo.getModuleId() == null){
            Long id = SequenceUtil.genEntitySequenceNo(InstanceInfo.class);
            moduleInfo.setModuleId(id);
            JPAUtil.create(moduleInfo);
        }else{
            JPAUtil.update(moduleInfo);
        }
        return moduleInfo;
    }
