在src中新建struts.xml文件：

<?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><constant name="struts.objectFactory" value="sjsp</result>            </action>            <action name="clas" class="clasAction">            <result name="success" type="redirect">/clasquery.action</result>            </action>        </package></struts> 

ClasAction.java文件：

package com.school.action;import com.school.entity.Clas;import com.school.service.ClasService;import com.opensymphony.xwork2.ActionSupport;@SuppressWarnings("serial")public class ClasAction extends ActionSupport {        private ClasService clasService;    public void setClasService(ClasService clasService) {        this.clasService = clasService;    }        private Clas clas;    public String execute(){        Clas c=new Clas();        c.setName(clas.getName());        c.setComment(clas.getComment());        clasService.saveClas(c);        return SUCCESS;    }        public Clas getClas() {        return clas;    }        public void setClas(Clas Clas) {        this.clas = Clas;    }}

ClasQueryAction.java文件：

package com.school.action;import java.util.List;import org.apache.struts2.ServletActionContext;import com.opensymphony.xwork2.ActionSupport;import com.school.entity.Clas;import com.school.service.ClasService;@SuppressWarnings("serial")public class ClasQueryAction extends ActionSupport {        private ClasService clasService;        // 設置業務邏輯組件    public void setClasService(ClasService clasService) {        this.clasService = clasService;    }        public String execute(){                List<Clas> claslist = clasService.findAll();            // 將所有課程存放在request范圍內            ServletActionContext.getRequest().setAttribute("claslist", claslist);            return SUCCESS;    }    }
