符合Restful风格的前后台编写方法

前台ajax访问:

$.ajax({
		type : 'post',
		url : '/dyncContractSign',
		data: JSON.stringify({
			contractId: $("#contractCustomId").val(),
			contractTemplateId: $("#contractTemplateId").val(),
			contractHtmlCode: $("#htmlShow").html()
		}),
		contentType: "application/json; charset=utf-8",  
        dataType: "json",
		success : function(data) {
			var flag = data.status ==="false" ? false : true;
			if(flag){
				var contractcReturn = JSON.parse(data.reJson);
				var contractCustomId = contractcReturn.contractCustomId;
				var shopContractSign = JSON.stringify(contractcReturn.shopContractSign);
				$("#shopContractSign").val(shopContractSign);
				console.log("shopContractSign:" + shopContractSign);
				$("#contractCustomId").val(contractCustomId);
				console.log("contractCustomId:" + contractCustomId);
				
				toastr.success("数据提交成功！");
			}else{
				toastr.error("数据提交失败！"); 
			}
		}
	});

后台:

@RestController
public class ShopContractSignController {

@ApiOperation(value = "合同自定义签署")
	@RequestMapping(value = "/dyncContractSign", method = RequestMethod.POST, produces = "application/json;charset=UTF-8")
	@ResponseBody
	public ConInterfaceRet dyncContractSign(@ApiParam(value = "合同自定义签署VO", required = true) @RequestBody ContractCustomVo contractCustomVo) {
		ConInterfaceRet cifr = new ConInterfaceRet();
		DyncContractCodeReVo dyncContractCodeReVo = contractCustomService.contractCustomSave(contractCustomVo);
		if (ObjectUtils.isEmpty(dyncContractCodeReVo)) {
			cifr = ReStatus.failed("contract save false");
		} else {
			cifr = ReStatus.success(dyncContractCodeReVo);
		}
		return cifr;
	}
}
