MVCFramework

自己写的简单版的MVC的Framework

 

• 使用说明
  • web.xml 中添加如下servlet

    	<servlet>
    		<servlet-name>appServlet</servlet-name>
    		<servlet-class>com.mvc.ServletDispatcher</servlet-class>
    		<init-param>
    			<param-name>scanPackage</param-name>
                            <!--  项目的总包名，包含所有需要的类的包名 -->
    			<param-value>com.jiabo.taskmanager</param-value>
    		</init-param>
    	</servlet>
    	<servlet-mapping>
    		<servlet-name>appServlet</servlet-name>
    		<url-pattern>/</url-pattern>
    	</servlet-mapping>    
    

    　　

  • 继承Application类。
• 注解支持

@Autowired -- 自动填充
@Controller -- 类似spring mvc controller
@PathVariable -- 类似spring mvc PathVariable
@RequestMapping -- 路由映射 目前只支持路径映射
@ResponseBody -- 类似spring mvc ResponseBody
@Service -- 类似spirng mvc Service

• 工具类支持
  • BaseUtil
    • getMethodParamsName
  • ClassUtil
    • getClasses
  • PropertiesUtil
    
    • 　　isDevMode
  • UploadUtil
    
    • getFiles
    • getFileName
• 接口支持
  • Application
    • 必须要实现的类，项目启动类

      package com.mvc;
      
      import java.util.List;
      
      /**
       * the class for the detail application to implement.
       * 
       * @author jialong
       *
       */
      public abstract class Application {
          private ViewResolver viewResolver;
      
          private List<HandlerInterceptorAdapter> interceptor;
      
          /**
           * get application name
           * 
           * @return name
           */
          public abstract String getAppName();
      
          /**
           * application init
           */
          public abstract void start();
      
          public List<HandlerInterceptorAdapter> getInterceptor() {
              return interceptor;
          }
      
          public void setInterceptor(List<HandlerInterceptorAdapter> interceptor) {
              this.interceptor = interceptor;
          }
      
          public ViewResolver getViewResolver() {
              return viewResolver;
          }
      
          public void setViewResolver(ViewResolver viewResolver) {
              this.viewResolver = viewResolver;
          }
      }

       

  • ViewResolver
    • 只需要一个实现类

      package com.mvc;
      
      import javax.servlet.ServletContext;
      import javax.servlet.http.HttpServletRequest;
      import javax.servlet.http.HttpServletResponse;
      /**
       * view resolver
       * @author jialong
       *
       */
      public interface ViewResolver {
          /**
           * call the method when the application start
           * @param context
           */
          void init(ServletContext context);
      
          /**
           * resolver the view
           * @param hreq
           * @param hres
           * @param path
           */
          void resolve(HttpServletRequest hreq, HttpServletResponse hres, String path);
      }

       

      　　
  • HandlerInterceptorAdapter
    • 实现该接口的类按照扫描到的顺序执行

  • package com.mvc;
    
    
    import javax.servlet.http.HttpServletRequest;
    import javax.servlet.http.HttpServletResponse;
    /**
     * Interceptor for this framework
     * @author jialong
     *
     */
    public interface HandlerInterceptorAdapter {
        /**
         * call the method before controller
         * @param request
         * @param response
         */
        void postHandle(HttpServletRequest request, HttpServletResponse response);
        /**
         * call the method after view resolver
         * @param request
         * @param response
         */
        void afterHandle(HttpServletRequest request, HttpServletResponse response);
    }
