1.前端传递基本数据类型数组
前端ajax

                            var item = new Array();var resources = new Array();bind.forEach(function (value,index) {$('select#item').get(0).selectedIndex=index;item.push($('select#item').val()[0]);resources.push(value);})$.ajax({url:'/workFlow/get/flow',                   traditional:true,                   method:'POST',                  data:{items:item,resources:resources},error:function(xhr,error,exception){alert(error+'\r\n'+exception);},success:function(){alert("success");}})

后端

@PostMapping(value = "/get/flow")public ModelAndView getFlow(@RequestParam(value = "items") String[] items,@RequestParam(value = "resources")List<List<String>> resources){for(int i=0;i<items.length;i++){System.out.println(items[i]);}System.out.println(resources.size());for(List<String> list:resources){System.out.println(list.size());for(String resource:list){System.out.print(resource);}System.out.println();}return new ModelAndView("index");}

2.前端传递bean数组
前端

                        var _data = $("#bootstrap-table").bootstrapTable('getData',false);$.ajax({type:'post',url:'/resources/updateSys',cache:false,traditional:true,data:JSON.stringify(_data),dataType:'json',contentType:'application/json',error:function(xhr,error,infos){alert(error+"\r\n"+infos);},success:function(data,status){//tableDatas=$('#bootstrap-table').bootstrapTable('getData');alert("更新成功");}});

后端

@PostMapping(value="/updateSys")public void updateResourceSys(@RequestBody ResourceSyss[] datas) {for(ResourceSyss data:datas) {System.out.println("out : "+data.toString());}}

3.总结和注意事项

• 在传递对象数组时，对象bean必须有setXX方法，因为注入方式是采用setXX方法注入；
• 传递对象数组时，必须使用@RequestBody注解，而传递基本数据类型时可以采用@RequestParam注解
• 使用@RequestParam时，上面例子里，value=“items”如果ajax里traditional=false则需改成value=“items[]”
