ajax post到后台中文乱码问题

以json字符串形式发送
1.js方面 以json形式进行发送 注意：contentType是要发送的数据类型，而Type是要接收的数据类型
function loadContentShow() {

$.ajax({

contentType:"application/json;chartset=utf-8",

scriptCharset:"utf-8",

type:"post",

url:"/Admin/add/result",

data:arrayToJsonString($("#myform").serializeArray()) ,

success:function (datas) {

$("#contentShow").html(datas);

return false;

},

error:function () {

alert("请求失败");

}

});

}
//将表单数组转化为json字符串 //formArray转json字符串 function arrayToJsonString(formArray){

var dataArray = {}; $.each(formArray,function(){ if(dataArray[this.name]){

if(!dataArray[this.name].push){

dataArray[this.name] = [dataArray[this.name]];

}

dataArray[this.name].push(this.value || "");

}else{

dataArray[this.name] =this.value || "";

}

}); return JSON.stringify(dataArray);

} 2.web.xml方面 需要在web.xml中设置编码过滤器 <!--编码过滤器--> <filter>

<filter-name>springUtf8Encoding</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>springUtf8Encoding</filter-name> <url-pattern>/*</url-pattern>

</filter-mapping>
3.springMVC方面 3.1 controller方面 @RequestMapping(value ="/Admin/add/result", method = RequestMethod.POST) ModelAndView AdminAddResult(@RequestBodyString param) {

//使用fastjson对json字符串进行格式转换

Map map = (Map) JSON.parse(param); ModelAndView modelAndView = new ModelAndView("result"); modelAndView.addObject("result", param); returnmodelAndView;

} 3.2 springMVC配置方面 <!--设置使用注解的类所在的jar包--> <context:component-scanbase-package="com.myblog.controller"/>
//以下是到数据库时乱码 4.数据库配置方面 #一定不要忘了在url后面加上编码方式 #jdbc jdbc.driver=com.mysql.jdbc.Driver jdbc.url=jdbc:mysql://localhost:3306/db_blog?useUnicode=true&characterEncoding=UTF-8 jdbc.uid=xxx jdbc.pwd=xxx jdbc.maxActive=20 jdbc.initialSize=0 jdbc.maxWait=60000
