Struts2自定义局部类型转换器

一、AddUAction
package com;
import java.util.Date;
public class AddUAction {
private Date birdate;
public Date getBirdate() {
return birdate;
}
public void setBirdate(Date birdate) {
this.birdate = birdate;
}
public String addU(){
System.out.println(birdate);
return "ok";
}
}
二、struts.xml
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.1//EN" "http://struts.apache.org/dtds/struts-2.1.dtd">
<struts>
<package name="te" namespace="/te" extends="struts-default">
<action name="teMan" class="com.AddUAction" method="addU">
<result name="ok">/index.jsp</result>
</action>
</package>
</struts>

三、DateConverter
package com;
import java.util.Date;
import java.text.SimpleDateFormat;
import java.util.Map;
import com.opensymphony.xwork2.conversion.impl.DefaultTypeConverter;
public class DateConverter extends DefaultTypeConverter {
@Override
public Object convertValue(Map<String, Object> context, Object value,
   Class toType) {
SimpleDateFormat dateFormat=new SimpleDateFormat("yyyyMMdd");
try{
   if(toType==Date.class){
    String[] params=(String[]) value;
    return dateFormat.parse(params[0]);
   }else{
    Date date=(Date) value;
    return dateFormat.format(date);
   }
}catch (Exception e) {
   return null;
}
}
}

四、AddUAction-conversion.properties
birdate=com.DateConverter
五、包结构

六、在地址栏输入
http://localhost:8080/test/te/teMan!addU?birdate=20010205

七、结果会在jsp页面显示出来
This is my JSP page.
