【java实例】自己动手实现IOC和MVC（八）

来对上一节实现的mvc做个测试吧首先dao层PersonDao.Java.这里做一些假数据

package com.ajun.ts.dao;

import java.util.ArrayList;

import java.util.List;

import com.ajunframework.beans.annotation.Dao;

@Dao

public class PersonDao{

    public List<String> findAll(){

        List<String> list = new ArrayList<String>();

        list.add("zhao");

        list.add("jun");

        list.add("liu");

        list.add("zhen");

        return list;

    }

}

service层PersonService.java

package com.ajun.ts.service;

import java.util.List;

import com.ajun.ts.dao.PersonDao;

import com.ajunframework.beans.annotation.Property;

import com.ajunframework.beans.annotation.Service;

@Service

public class PersonService {

    @Property

    private PersonDao personDao;

    public List<String> findAll(){

        return personDao.findAll();

    }

    public PersonDao getPersonDao() {

        return personDao;

    }

    public void setPersonDao(PersonDao personDao) {

        this.personDao = personDao;

    }

}

action层PersonAction.java

package com.ajun.ts.controller;

import java.util.List;

import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpServletResponse;

import com.ajun.ts.service.PersonService;

import com.ajunframework.beans.annotation.Action;

import com.ajunframework.beans.annotation.Property;

import com.ajunframework.servlet.annotation.RequestMapping;

import com.ajunframework.servlet.view.View;

import com.ajunframework.servlet.view.ViewData;

@Action

public class PersonAction {

    @Property

    private PersonService personService;

    @RequestMapping("person/list")//跳转路径

    public View personList(HttpServletRequest request, HttpServletResponse response){

        ViewData view = new ViewData();

        List<String> list = personService.findAll();

        view.put("list", list);//此处就是设置数据在request范围内了

        return new View("/jsp/person/list.jsp");

    }

    public PersonService getPersonService() {

        return personService;

    }

    public void setPersonService(PersonService personService) {

        this.personService = personService;

    }

}

配置注入的扫描的包constant.properties

scan-package=com.ajun.ts//这个包先必须在classpath下，没有做路径的处理

配置DispatchServlet在web.xml

<?xml version="1.0" encoding="UTF-8"?>

<web-app version="2.5"

    xmlns="http://java.sun.com/xml/ns/javaee"

    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee

    http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">

  <servlet>

    <servlet-name>DispatchServlet</servlet-name>

    <servlet-class>com.ajunframework.servlet.DispatchServlet</servlet-class>

  </servlet>

  <servlet-mapping>

    <servlet-name>DispatchServlet</servlet-name>

    <url-pattern>*.ajun</url-pattern>

  </servlet-mapping>

  <welcome-file-list>

    <welcome-file>index.jsp</welcome-file>

  </welcome-file-list>

</web-app>

页面请求

<a href="person/list.ajun">LSIT PERSON</a>

展现页面

<table border="1" align="center" width="80%">

        <tr>

            <td>Name</td>

        </tr>

        <c:forEach items="${list}" var="p">

            <tr>

                <td>${p}</td>

            </tr>

        </c:forEach>

    </table>

好了，至此整个自己动手实现IOC和MVC完成了，希望对大家有帮助
