XMLConfiger 适合用来读取简单的配置文件

下面是生成的xml文件。<?xml version="1.0" encoding="UTF-8"?>
<java version="1.5.0_12" class="java.beans.XMLDecoder">
 <object class="com.movo.tv.test.Goo">
  <void property="id">
   <string>111</string>
  </void>
  <void property="name">
   <string>2222</string>
  </void>
  <void property="stu">
   <object class="com.movo.tv.test.Student">
    <void property="age">
     <int>17</int>
    </void>
    <void property="stuName">
     <string>sary</string>
    </void>
   </object>
  </void>
 </object>
</java>


2.应用。
//movo后台管理人员登陆用。
 public String movLogin() throws HttpException, IOException {
 //System.out.println("进来了::::::::::::::::"); 
//现在的表里没有系统管理员的字段这里暂时用硬编码
  String[]sysAdminNames=com.movo.tv.common.util.SystemConfig.getInstance().getConfiguration().getStringArray("sys.admins");
  boolean istrue=false;
  for(int i=0;i<sysAdminNames.length;i++){
   String[]n_p = sysAdminNames[i].toString().split(":");
   if(email.equals(n_p[0])&&passWord.equals(n_p[1])){
    log.info("right email:"+n_p[0]+" now email::"+email);
    log.info("right pass:"+n_p[1]+" now pass::"+passWord);
   ServletActionContext.getRequest().getSession().setAttribute("movoAdmin","yes");
    istrue = true;
   }
   /*if("huanglei".equals(n_p[0])&&"123456".equals(n_p[1])){
       istrue = true;
    }*/
  }
  if(istrue){
   Object toWhere = ServletActionContext.getRequest().getParameter("loginWhere");
   if(toWhere!=null){
    if(toWhere.equals("movo"))
     return "movologinSeccess";
    else if(toWhere.equals("operation"))
       return "toOperation";///yoperate!manageYeDian.do
   }
   return "movologinSeccess";
   
  }// System.out.print(":::::::::::是系统管理员");
  else return "movologinFail";// System.out.print("::::::::::::不是管理员");
  
 }

而XMLEncoder,XMLDecoder 是用来序列化javaBean和反序列化javaBean的。

  • # tomcat4.X 中的html显示为乱码!为什么?  zlj Posted @ 2008-09-09 13:26
    -----------------------------------------------------------------------------------------

    我的tomcat4.1.29中的加载html文件静态文件会有乱码!
    而显示jsp不会有乱码,请用怎么解决? 要配置什么tomcat的xml文件吗?

    我现在知道一个解决方法是把index.html文件用记事本打开然后另存为UTF-8格式后就不会乱码了。可是这只能治标不治本啊!谁有完全解决方法? 谢谢!
    =========================================================================
    加入配置:
    <mime-mapping>
    <extension>htm</extension>
    <mime-type>text/html;charset=gb2312</mime-type>
    </mime-mapping>
    <mime-mapping>
    <extension>html</extension>
    <mime-type>text/html;charset=gb2312</mime-type>
    </mime-mapping>

    谢谢,使用以上方法解决了!!!

    解决方法是,修改tomcat程序目录下的 /webapps/web_inf/web.xml 文件,

    添加一段配置代码:

    <mime-mapping>
    <extension>htm</extension>
    <mime-type>text/html;charset=gb2312</mime-type>
    </mime-mapping>
    <mime-mapping>
    <extension>html</extension>
    <mime-type>text/html;charset=gb2312</mime-type>
    </mime-mapping>

    即可解决tomcat中浏览html乱码问题!

    如果想解决所有tomcat所有工程乱码,则应修改 tomcat目录下 \conf\web.xml 文件即可。

    谢谢!!!!


    ---------------------------------------------------------------
    还有一种解决方法是将tomcat和Apache结合一下就行了,让Apache解释html,让tomcat解释jsp等文件。然后修改只需修改Apache配置就行了。
    在Apache的conf文件夹下,httpd.conf,里面有AddDefaultCharset ISO-8859-1,你把它改成 AddDefaultCharset GB2312。
    -------------------------------------------------------------------------------------------------------------------------------------------------------
