basis MVC

  • 基于servlet与java注解的Web MVC 快速开发框架
  • basis 意思: n. 基础;底部;主要成分;基本原则或原理

代码可能不够好,重复造轮子是为了更加充分的了解框架底层实现原理,写这个这是一种尝试,一种突破自我的方式。欢迎提出建议!谢谢!

基于Java注解和servlet实现通过注解方式访问的web MVC框架

示例项目basisEdp

规范了包名,所以重新创建了项目进行提交分享点击这里可以查看更早前的更新日志

TODO 真实项目的开发 basisEdp

现已实现以下功能

IOC、AOP、ORM、MVC

集成quartz,beetl

参数类

- 实现缓存扫描注解action
- 实现参数自动绑定
- 参数与javabean自动绑定
- 文件上传自动绑定

文件类

- 实现文件过滤器
- 上传文件格式控制
- 上传文件大小限制

基础视图控制器

- jsp页面返回
- json对象返回
- 404、500页面
- 文件下载

用户自定义视图模版引擎控制器

 - 顾名思义,就是可以由开发者自定义的视图模版引擎 (如freemaker,beetl,vm等等)

dao功能 简易的orm实现

- table-List<对象>
- table-对象
- table-Map
- table-List<Map>
- 对象的增删改查
- dao事务控制
  • @Setup 启动执行任务
  • 绑定durid连接池

规范

- WEB-INF下的jsp必须通过action访问
- 静态资源文件目录需要配置
- 配置文件相关可以查看jar包中的 resources 目录以作规范

###webxml设置

  <!--basis框架过滤器-->
    <listener>
        <listener-class>com.sgaop.basis.web.ServletInitListener</listener-class>
    </listener>
    <filter>
        <filter-name>basisFilter</filter-name>
        <filter-class>com.sgaop.basis.web.BasisMvcWebFilter</filter-class>
    </filter>
    <filter-mapping>
        <filter-name>basisFilter</filter-name>
        <url-pattern>/*</url-pattern>
        <dispatcher>REQUEST</dispatcher>
        <!--内部转发需要设置 FORWARD-->
        <dispatcher>FORWARD</dispatcher>
        <dispatcher>INCLUDE</dispatcher>
    </filter-mapping>

注册数据源和自定义视图就这么简单

 public void init(ServletContextEvent servletContextEvent) {
        ViewsRegister.registerView("freemarker", FreeMarkerView.class);
        ViewsRegister.registerView("beetl", BeetlView.class);
        //注册数据源1
        DaosRegister.registerDao("daoA", DaoImpl.class, getDsA());
        //注册数据源2
        DaosRegister.registerDao("daoB", DaoImpl.class, getDsB());
    }

示例CODE

package com.sample.action;

import com.sample.entity.Topic;
import com.sgaop.basis.annotation.*;
import com.sgaop.basis.dao.Dao;
import com.sgaop.basis.mvc.AjaxResult;
import com.sgaop.basis.trans.TransAop;

import javax.servlet.http.HttpServletRequest;
import java.sql.SQLException;
import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;
