继续犯错误，即使我搜索了这个网站并尝试了一切。非常感谢一些帮助。问题在于AddUser页面上的Jquery / JSON请求。我已经添加了两个Jackson jar文件（核心和映射。）它部署在Tomcat 7上。
这是配置文件：
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

</bean>

<bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/jsp/"/>
<property name="suffix" value=".jsp"/>
</bean>
</beans>
这是控制器：
@RequestMapping(value="/AddUser.htm", method=RequestMethod.POST)
public @ResponseBody JsonResponse addUser(@ModelAttribute (value="player") Player player, BindingResult result){
JsonResponse res = new JsonResponse();
ValidationUtils.rejectIfEmpty(result, "name", "Name can not be empty.");
if(!result.hasErrors()){
htmlPlayerNo++;
player.setHtmlPlayerNo(htmlPlayerNo);
players.add(player);
res.setStatus("SUCCESS");
res.setResult(players);
}else{
res.setStatus("FAIL");
res.setResult(result.getAllErrors());
}
return res;
}
这些是chrome调试器的标题：

这是我的JQuery代码：
function doAjaxPost() {
// get the form values
var name = $('#name').val();
$.ajax({
type: "POST",
url: contexPath + "/AddUser.htm",
data: "name=" + name,
success: function(response){
// we have the response
if(response.status == "SUCCESS"){
userInfo = "<ol>";
for(var i =0; i < response.result.length ; i++){
userInfo += "<br><li><b>Name</b> : " + response.result[i].name;
}
userInfo += "</ol>";
$('#info').html("User has been added to the list successfully. " + userInfo);
$('#name').val('');
$('#error').hide('slow');
$('#info').show('slow');
}else{
errorInfo = "";
for(i =0 ; i < response.result.length ; i++){
errorInfo += "<br>" + (i + 1) +". " + response.result[i].code;
}
$('#error').html("Please correct following errors: " + errorInfo);
$('#info').hide('slow');
$('#error').show('slow');
}
},
error: function(e){
alert('Error '+ e);
}
});
}

答案 0 :(得分：0)
我做了返回json的代码，但是像这样的String数据类型格式：
[
{
"name": "Jason",
"number": "10"
},
{
"name": "Jimmy",
"number": "11"
}
]
功能大致如下：
@RequestMapping(value = "product", method = RequestMethod.GET, headers = "Accept=*/*")
public @ResponseBody
String addUser(@RequestParam("term") String query) {
String json = "[{\"name\": \"Jason\",\"number\": \"10\" }, {\"name\": \"Jimmy\",\"number\": \"11\" }]";
System.out.println(json);
return json;
}
我不使用杰克逊或罐子。对不起，我只知道自己的方式，可能是其他人可以更清楚地解释。
