Struts2 页面往action中传值乱码 问题，页面alert不乱码，传到action中就乱码。后来将值传入model中，不乱码

修改前：
url : "spinglunAdd.action?content= newcontent)+ "&itemid=" + itemid
+ "&receiveuserid="+receiveuserid+"&itemtype=question&path=<%=basePath%>",


public class QuestionentityManagerAction extends ActionSupport implements ServletRequestAware{
private Spinglun spinglun=new Spinglun();
spinglun.setItemid(itemid);

spinglun.setReceiveuserid(receiveuserid);
spinglun.setCreatetime(new Date().getTime()+"");
spinglun.setItemtype(itemtype);
spinglun.setContent(content);
public Spinglun getSpinglun() {
return spinglun;
}
public void setSpinglun(Spinglun spinglun) {
this.spinglun = spinglun;
}
}
修改后：
url : "spinglunAdd.action?spinglun.content= encodeURI(newcontent) + "&spinglun.itemid=" + itemid
+ "&spinglun.receiveuserid="+receiveuserid+"&spinglun.itemtype=question&path=<%=basePath%>",


public class QuestionentityManagerAction extends ActionSupport implements ServletRequestAware{
private Spinglun spinglun=new Spinglun();
public Spinglun getSpinglun() {
return spinglun;
}
public void setSpinglun(Spinglun spinglun) {
this.spinglun = spinglun;
}
}
为啥放到对象中就不乱吗了？？？？？如果按修改前的方式传值，是不是需要配置过滤器，在web.xml中
