搭建ssh框架项目（五）

一、控制层优化

　　（1）创建BaseAction.java类

package com.cppdy.ssh.web.action;

import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpServletResponse;

import org.apache.struts2.interceptor.ServletRequestAware;

import org.apache.struts2.interceptor.ServletResponseAware;

import com.opensymphony.xwork2.ActionSupport;

@SuppressWarnings("serial")

public class BaseAction extends ActionSupport implements ServletRequestAware,ServletResponseAware {

    protected HttpServletRequest request = null;

    protected HttpServletResponse response = null;

    public void setServletRequest(HttpServletRequest request) {

        this.request = request;

    }

    public void setServletResponse(HttpServletResponse response) {

        this.response = response;

    }

}

BaseAction.java

　　（2）创建ServiceProviderCord.java类

package com.cppdy.ssh.container;

import org.springframework.context.ApplicationContext;

import org.springframework.context.support.ClassPathXmlApplicationContext;

public class ServiceProviderCord {

    protected static ApplicationContext ac;

    /**

    * @Name: load

    * @Description: 加载beans.xml文件(filename放置的是beans.xml)

    * @Parameters: String filename（传递beans.xml文件）

    * @Return: 无

    */

    public static void load(String filename){

        ac = new ClassPathXmlApplicationContext(filename);

    }

}

ServiceProviderCord.java

　　（3）创建ServiceProvider.java类

package com.cppdy.ssh.container;

import org.apache.commons.lang.StringUtils;

public class ServiceProvider {

    public static ServiceProviderCord spc;

    //加载beans.xml文件

    static{

        spc = new ServiceProviderCord();

        spc.load("beans.xml");

    }

    /**

    * @Name: getService

    * @Description: 自定义spring容器，加载服务节点

    * @Parameters: String serviceName 服务节点名称

    * @Return: Object 服务接口

    */

    public static Object getService(String serviceName){

        if(StringUtils.isBlank(serviceName)){

            throw new RuntimeException("当前服务名称不存在");

        }

        Object object = null;

        if(spc.ac.containsBean(serviceName)){

            object = spc.ac.getBean(serviceName);

        }

        if(object==null){

            throw new RuntimeException("当前服务名称【"+serviceName+"】下的服务节点不存在");

        }

        return object;

    }

}

ServiceProvider.java

　　（4）修改ElecTextAction.java的save方法，将数据保存入库

package com.cppdy.ssh.web.action;

import java.util.Date;

import com.cppdy.ssh.container.ServiceProvider;

import com.cppdy.ssh.domain.ElecText;

import com.cppdy.ssh.service.IElecTextService;

import com.cppdy.ssh.web.form.ElecTextForm;

import com.opensymphony.xwork2.ModelDriven;

@SuppressWarnings("serial")

public class ElecTextAction extends BaseAction implements ModelDriven<ElecTextForm>{

    private IElecTextService elecTextService = (IElecTextService)ServiceProvider.getService("elecTextService");

    private ElecTextForm elecTextForm = new ElecTextForm();

    public ElecTextForm getModel() {

        return elecTextForm;

    }

    /**

    * @Name: save

    * @Description: 保存ElecText对象的方法

    * @Parameters: 无

    * @Return: 跳转到system/textAdd.jsp

    */

    public String save(){

        //System.out.println(elecTextForm.getTextName());

        //VO对象转换成PO对象

        //实例化PO对象

        ElecText elecText = new ElecText();

        elecText.setTextName(elecTextForm.getTextName());//测试名称

        elecText.setTextDate(new Date());//测试日期

        elecText.setTextRemark(elecTextForm.getTextRemark());//测试备注

        elecTextService.saveElecText(elecText);

        return "save";

    }

}

ElecTextAction.java

二、测试新增功能

三、查看数据库

四、项目结构
