服務器用的是Springmvc，接口內容：

1. @ResponseBody
2. @RequestMapping(value="/order",method=RequestMethod.POST)
3. public boolean order(HttpServletRequest request,@RequestBody List<Order> orders) throws Exception {
4. AdmPost admPost = SessionUtil.getCurrentAdmPost(request);
5. if(admPost == null){
6. throw new RuntimeException("[OrderController-saveOrUpdate()] 當前登陸的用戶職務信息不能為空！");
7. }
8. try {
9. this.orderService.saveOrderList(orders,admPost);
10. Loggers.log("訂單管理",admPost.getId(),"導入",new Date(),"導入訂單成功,訂單信息--> " + GsonUtil.toString(orders, new TypeToken<List<Order>>() {}.getType()));
11. return true;
12. } catch (Exception e) {
13. e.printStackTrace();
14. Loggers.log("訂單管理",admPost.getId(),"導入",new Date(),"導入訂單失敗,訂單信息--> " + GsonUtil.toString(orders, new TypeToken<List<Order>>() {}.getType()));
15. return false;
16. }
17. }

通過ajax訪問的時候，代碼如下：

1. $.ajax({
2. type : "POST",
3. contentType : "application/json; charset=utf-8",
4. url : ctx + "order/saveOrUpdate",
5. dataType : "json",
6. anysc : false,
7. data : {orders:[{orderId:"11",createTimeOrder:"2015-08-11"}]}, // Post 方式，data參數不能為空""，如果不傳參數，也要寫成"{}"，否則contentType將不能附加在Request Headers中。
8. success : function(data){
9. if (data != undefined && $.parseJSON(data) == true){
10. $.messager.show({
11. title:‘提示信息‘,
12. msg:‘保存成功！‘,
13. timeout:5000,
14. showType:‘slide‘
15. });
16. }else{
17. $.messager.alert(‘提示信息‘,‘保存失敗!‘,‘error‘);
18. }
19. },
20. error : function(XMLHttpRequest, textStatus, errorThrown) {
21. alert(errorThrown + ‘:‘ + textStatus); // 錯誤處理
22. }
23. });

通過HttpClient方式訪問，代碼如下：

1. package com.ec.spring.test;
3. import java.io.IOException;
4. import java.nio.charset.Charset;
6. import org.apache.commons.logging.Log;
7. import org.apache.commons.logging.LogFactory;

77. status = 1;
78. }
80. // Read the response body
81. body = EntityUtils.toString(response.getEntity());
83. } catch (IOException e) {
84. // 網絡錯誤
85. status = 3;
86. } finally {

101. System.out.println(ac.post(arry.toString()));
102. }
104. /**

109. public int getStatus() {
110. return status;
111. }
113. /**

HttpClient通過Post方式發送Json數據
