springboot 前后端参数交互方式Get 方式:1. localhost:8080/index?id=1@RequestParam(value = “grade”, defaultValue = “”) String grade)2.localhost:8080/index/{reportType}localhost:8080/index-{reportType} @RequestMapping("/commonReportForm/{reportType}") @ResponseBody public ModelAndView index(@PathVariable(name = “reportType”, required = false) Integer reportType, ModelAndView mv) { ….} @RequestMapping("/commonReportForm-{reportType}") @ResponseBody public ModelAndView index(@PathVariable(name = “reportType”, required = false) Integer reportType, ModelAndView mv) { ….} Post 方式:直接以一个bean接收public Object save( User user) {….}前端传参方式:form 表单 - * input 中 name 要与 bean中的属性名相同ajax ： $.ajax({ type: “POST”, url: dbrwListpath, data: { “id”: id, “name”: name, }, dataType: “json”, success: function (data) { //do something.. }, error: function (data) { //do something.. } });json 传参方式：public Object save(@RequestBody User user) {….}前端ajax： $.ajax({ type: “POST”, headers: { ‘Accept’: ‘application/json’, ‘Content-Type’: ‘application/json’ }, url: dbrwListpath, data: { “id”: id, “name”: name, }, dataType: “json”, success: function (data) { //do something.. }, error: function (data) { //do something.. } }); Dto 封装方式：public Object save(@RequestBody DataDto dto) {….}public class DataDto{ //学校id private Integer schoolId; //幼儿信息 private List<User> users; //get set …}前端ajax数据格式：//示例 var user = []; for (var i = 0; i < clen; i++) { var c = {}; c.id = 1; c.name = tom; user.push(c); }//datas属性名需与Dto实体的属性名相同var datas = { schoolId:schoolId, user:user }; $.ajax({ type: “POST”, headers: { ‘Accept’: ‘application/json’, ‘Content-Type’: ‘application/json’ }, url: “/comprehensiveDeclaration/comprehensive-” + comprehensiveId + “/step1-save”, data: JSON.stringify(datas), dataType: “json”, success: function (response) { //do something.. }, error: function (data) { //do something.. } });
