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;    
    }
    
}

　　（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);
    }
}

　　（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;
    }
}

　　（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";
    }

    
}

二、测试新增功能

三、查看数据库

四、项目结构
