JQuery發送ajax請求時中文亂碼

先排除項目故障：

1.web.xml中是否配置了字符攔截器

        <filter>
		<filter-name>encodingFilter</filter-name>
		<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
		<init-param>
			<param-name>encoding</param-name>
			<param-value>utf-8</param-value>
		</init-param>
		<init-param>
			<param-name>forceEncoding</param-name>
			<param-value>true</param-value>
		</init-param>
	</filter>
	<filter-mapping>
		<filter-name>encodingFilter</filter-name>
		<url-pattern>/*</url-pattern>
	</filter-mapping>

2.jsp頁面是不是utf-8

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>

順便也加上這個標簽,統一發送utf-8，不過聽說有些雞肋

<meta http-equiv=”content-type” content=”text/html; charset=UTF-8″ />

3.在排除了故障后，將ajax請求改為post請求

 $.ajax({
		url:"list",
		type:'post',
		data:{
			param:recode,
			city:locationActive
		},
		dataType: 'json',//要求服務器返回的是json
		success:function(res){}
