java web MVC 轻量级框架 一个非常简单的MVC框架，实现了类似Spring MVC的基本功能。 1、包括自动扫描绑定映射路径，只要在web.xml中指定扫描包，系统启动后会将请求url绑定到指定的处理方法上。如： 在web.xml中定义如下： ScanPackage com.mvc.controller 容器在启动时候，会将com.mvc.controller下所有映射路径绑定处理方法上，假如在扫描包中定义下列类: import javax.imageio.ImageIO; import javax.servlet.ServletOutputStream; import javax.servlet.http.Cookie; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import javax.servlet.http.HttpSession; import com.hxw.simple.light.mvc.annotation.MappingMethodAnnotation; import com.hxw.simple.light.mvc.view.SimpleModelView; import com.mvc.verification.VerificationCode; public class LoginController { @MappingMethodAnnotation(mappingMethod = "/login.do") public String login(HttpServletRequest request, HttpServletResponse response) { return "login/main"; } @MappingMethodAnnotation(mappingMethod = "/loginvm.do") public SimpleModelView loginView(HttpServletRequest request, HttpServletResponse response) { SimpleModelView mv = new SimpleModelView("login/mainmv"); Map m = new HashMap(); m.put("beij", "北京"); m.put("sha", "上海"); m.put("nanj", "南京"); mv.setAttribute("city", m); return mv; } @MappingMethodAnnotation(mappingMethod = "/Verify.do") public void service(HttpServletRequest arg0, HttpServletResponse arg1) throws IOException { HttpServletRequest request = (HttpServletRequest) arg0; HttpServletResponse response = (HttpServletResponse) arg1; response.setContentType("image/jpeg"); response.setHeader("Pragma", "No-cache"); response.setHeader("Cache-Control", "no-cache"); response.setDateHeader("Expires", 0); VerificationCode vCode = new VerificationCode(); BufferedImage bufferImage = vCode.getImageData(); HttpSession session = request.getSession(); response.addCookie(new Cookie("JSSESIONID", session.getId())); ServletOutputStream responseOutputStream = response.getOutputStream(); ImageIO.write(bufferImage, "JPEG", responseOutputStream); responseOutputStream.flush(); responseOutputStream.close(); } } 那么在接到url请求如：http://localhost:8080/TestSimpleMVC/loginvm.do 会调用指定的方法处理。 2、支持视图定义，在web.xml定义了视图路径后： DelegateForwardServlet com.hxw.simple.light.mvc.servlet.DelegateForwardServlet prefix /WEB-INF/view/ suffix .jsp DelegateForwardServlet /SYS_FORWARD_URL.fo 只需在执行完方法后，返回字符串：如return "login/main"就会跳转到指定视图，还可以在视图中用EL表单式访问modelview数据，例子如： SimpleModelView mv = new SimpleModelView("login/mainmv"); Map m = new HashMap(); m.put("beij", "北京"); m.put("sha", "上海"); m.put("nanj", "南京"); mv.setAttribute("city", m); return mv; 3、支持数据参数自动绑定如： @ParamAttribute(type = ParamaAttributeType.REQUEST, key = "userPassword") String s, @ParamAttribute(type = ParamaAttributeType.SESSION, key = "11212") String s1, @ParamAttribute(type = ParamaAttributeType.SERVLETCONTEXT, key = "32312") String s2, @ParamAttribute(type = ParamaAttributeType.REQUEST, key = "userNames") String[] s3 系统根据参数指定的范围，这指定范围内赋值到参数上，你还可以直接使用javabean做参数绑定，如： public class User extends PaginatedHelper { private static final long serialVersionUID = -8225389551152428829L; private String userName; private String userPassword; public User() { super(); } public User(String userName, String userPassword) { super(); this.userName = userName; this.userPassword = userPassword; } public String getUserName() { return userName; } public void setUserName(String userName) { this.userName = userName; } public String getUserPassword() { return userPassword; } public void setUserPassword(String userPassword) { this.userPassword = userPassword; } 在方法上带上 Uer user后，属性名称相同的数据就会赋值到javabean上。不必再使用繁琐的user.setUserName(request.getParameter("userName")); 3、简便的jdbc操作 有查询模板QueryTemplate,命名查询NamedQueryTemplate及bean作为参数的BeanQueryTemplate等。支持返回javabean类型，javabean列表， MAP类型，map列表类型，统计结果queryForInt等。
