前台AJAX传数组，后台的java接收

前台AJAX传数组，后台的java接收（后台接收前端发送的数组类型数据）两种解决方法

第一种方法，前端将数组通过JSON.stringify()方法转换为json格式数据，后台将接收的json数据转换为数组

function search() {
			var equiNames = JSON.stringify($("#equiNames").val());
			var startDate = $('#daterange-btn span').text().substring(0, 10);
			var endDate = $('#daterange-btn span').text().substring(13);
			$.ajax({
				url : "dataAcquisition/report",
				type : "post",
				dataType : "json",
				data : {
					"equiNames" : equiNames,
					"startDate" : startDate,
					"endDate" : endDate
				},
				success : function(result) {
					……
					}
				}
			});
		}

@RequestMapping("/report")
	public void report(String equiNames, String startDate, String endDate, HttpServletRequest request,
			HttpServletResponse response) throws ExecutionException, InterruptedException, IOException, ParseException {
		//将接收的json数据转换为数组
		List equiNameList = new Gson().fromJson(equiNames, new TypeToken>() {
		}.getType());
		List resultList = dataAcquisitionService.report(equiNameList, startDate, endDate);
		response.setContentType("application/json; charset=UTF-8");
		response.getWriter().write(new Gson().toJson(resultList));
	}

第二种方法，前端通过设置traditional属性为true直接传递数组 */,后台通过对象接收

function search() {
			var equiNames = JSON.stringify($("#equiNames").val());
			var startDate = $('#daterange-btn span').text().substring(0, 10);
			var endDate = $('#daterange-btn span').text().substring(13);
			$.ajax({
				url : "dataAcquisition/report",
				type : "post",
				dataType : "json",
                traditional : true,//用传统方式序列化数据
				data : {
					"equiNames" : equiNames,
					"startDate" : startDate,
					"endDate" : endDate
				},
				success : function(result) {
					……
					}
				}
			});
		}

对象

@RequestMapping("/report")
	public void report(ReportParaVo rp, HttpServletRequest request, HttpServletResponse response)
			throws ExecutionException, InterruptedException, IOException, ParseException {
		
		List resultList = dataAcquisitionService.report(rp);
		response.setContentType("application/json; charset=UTF-8");
		response.getWriter().write(new Gson().toJson(resultList));
	}

import java.util.List;

public class ReportParaVo {
	private List equiNames;
	private String startDate;
	private String endDate;

	public List getEquiNames() {
		return equiNames;
	}

	public void setEquiNames(List equiNames) {
		this.equiNames = equiNames;
	}

	public String getStartDate() {
		return startDate;
	}

	public void setStartDate(String startDate) {
		this.startDate = startDate;
	}

	public String getEndDate() {
		return endDate;
	}

	public void setEndDate(String endDate) {
		this.endDate = endDate;
	}

}

第二种方法效果如图所示
