最近在用Spring MVC做一个小的后台服务，遇到了ajax请求中的字符编码问题。
原文链接：https://www.f2er.com/ajax/165285.html
ajax请求如下：
function PostJSONQuery(json,on_success)
{
$.ajax({
url: "json.do",
contentType : "application/json;charset=utf-8",
processData : true,
data: json,
dataType: "json",
success: function(response) {
on_success(response);
},
error: function (xhr,ajaxOptions,thrownError) {
}
});
}
以上虽然设置了
charset=utf-8，但是好像没什么作用最后传到后台的还是?·?????·????，编码格式不对
function changeImagesAddress(){
alert("test");
var alert_query_json = {
effectname:"淡入淡出"
};
PostJSONQuery(alert_query_json,function(response){
alert("response");
alert(response.listInfo.length);//response 文件夹集合 response[i].value
//response[i].name
alert(response.listInfo[0].age);
});
}
一开始打算请求的中文字符转为utf-8，后来想想还是在服务端将字符转化为utf-8；
查资料知道/**http头默认以ISO-8859-1 格式传送中文字符**/ 所以在服务端将收到的字符进行重新编码
@RequestMapping(value="/jsp/changeImagesAddress")
@ResponseBody
public OneEffectImagesAddress validataUser(@RequestParam String effectname) throws UnsupportedEncodingException{
OneEffectImagesAddress infoList=null;
/**http头默认以ISO-8859-1 格式传送中文字符**/
String str_effectname=new String (effectname.getBytes("ISO-8859-1"),"utf-8");
infoList=DaoImpl.getOneEffectImagesAddress(str_effectname);
return infoList;
}
function PostJSONQuery(json,on_success)
{
$.ajax({
url: "json.do",
type:"post",
contentType : "application/json;charset=utf-8",
processData : true,
data: json,
dataType: "json",
success: function(response) {
on_success(response);
},
error: function (xhr,thrownError) {
}
});
}上面的可以发现一个问题，
contentType : "application/json;charset=utf-8",之前我在xml里面配置了
<bean class="org.springframework.web.servlet.view.ContentNegotiatingViewResolver">
<property name="mediaTypes">
<map>
<entry key="html" value="text/html"/>
<entry key="spring" value="text/html"/>
<entry key="json" value="application/json"/>
</map>
</property>
</bean>
这么一段，后来发现 这一段不需要也没关系。
contentType : "application/json;charset=utf-8"应该修改成
contentType : "application/x-www-form-urlencoded;charset=utf-8",
