package cn.qlq.util;import java.io.Serializable;public class ResultUtil<T> implements Serializable { ???private static final long serialVersionUID = 3637122497350396679L; ???private boolean success; ???private T data; ???private String msg; ???public ResultUtil() { ???} ???public ResultUtil(boolean success) { ???????this.success = success; ???} ???public boolean isSuccess() { ???????return success; ???} ???public void setSuccess(boolean success) { ???????this.success = success; ???} ???public T getData() { ???????return data; ???} ???public void setData(T data) { ???????this.data = data; ???} ???public String getMsg() { ???????return msg; ???} ???public void setMsg(String msg) { ???????this.msg = msg; ???} ???public ResultUtil(boolean success, String msg) { ???????super(); ???????this.success = success; ???????this.msg = msg; ???} ???public ResultUtil(boolean success, T data) { ???????super(); ???????this.success = success; ???????this.data = data; ???}}该类为前后台交互提供了非常大的便捷：
下面是前后台的ajax交互：
前台ajax代码：
$.ajax({ ???????????url: "<%=request.getContextPath()%>/supp/deleteSupp", ???????????data : {supplierId:supplierId}, ???????????async: false, //请求是否异步，默认为异步，这也是ajax重要特性 ???????????type: "GET", ??//请求方式 ???????????success: function(data) { ???????????????var rs = eval(‘(‘+data+‘)‘); ???????????????flag = rs.success; ???????????????if(flag){ ???????????????????alert("删除成功!"); ???????????????} ???????????} ???????});下面是后台java代码：
@RequestMapping("/deleteSupp") ???@ResponseBody ???public Result<String> deleteSupplier(HttpServletRequest request){ ???????Result<String> rs = new Result<>(); ???????String supplierId = request.getParameter("supplierId"); ???????supplierService.deleteSupplierById(supplierId); ???????rs.setSuccess(true); ???????return rs; ???}Ajax的Result工具类
