把下载好的displaytag中的css和img弄到WebRoot下， 请求的jsp
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>

struts.xml文件
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"

</struts>
找到对应的Action
package com.lbx.action;
import java.util.ArrayList;
import java.util.List;
import com.lbx.model.Student;
import com.opensymphony.xwork2.ActionSupport;
public class StudentAction extends ActionSupport {
private List<Student> students;
public String dispayAllStudents() {
// 定义一个list存放要显示的记录
students = new ArrayList<Student>();
for (int i = 0; i < 50; i++) {
Student student = new Student();
student.setName("lbx" + i);
student.setAge("lbx" + i);
student.setMark("lbx" + i);
students.add(student);
}
return SUCCESS;
}
public List<Student> getStudents() {
return students;
}
public void setStudents(List<Student> students) {
this.students = students;
}
}
Action中的Model
package com.lbx.model;
public class Student {
private String name;
private String age;
private String mark;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;

分页显示的jsp代码
<%@ page language="java" import="java.util.*,com.lbx.model.*"
pageEncoding="UTF-8"%>
<%@taglib uri="http://displaytag.sf.net" prefix="display"%>
<%
String path = request.getContextPath();

默认的情况下"下一页"什么的是英文的，所以我要手动的修改为中文，直接修改displaytag.properties文件（注意是处理过后的）
paging.banner.first = <span class\="pagelinks">[\u6700\u524D/\u4E0A\u4E00\u9875]{0}[<a href\="{3}">\u4E0B\u4E00\u9875</a>/<a href\="{4}">\u6700\u540E</a>]</span>
