2.java類的實現

2.1註解實現控制器

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.ModelAttribute;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.multiaction.MultiActionController;
@Controller
public class Hellocontroller extends MultiActionController {

@RequestMapping("/mylogin.action")
public ModelAndView mylogin(HttpServletRequest req, HttpServletResponse res) throws Exception
{
// RequestContext rc =new RequestContext(req);
// rc.getMessage("hello");
System.out.println(111);
ModelAndView mav= new ModelAndView("mylogin");
return mav;
}

@RequestMapping("/mysuccess.action")
public String mysuccess(@ModelAttribute("user") UserInfo user,Model model) throws Exception {
if(!(user.getId().matches("[0-9]{1,4}"))) {
throw new Exception("輸入的賬號格式錯誤!!!");
}
if(user.getId().equals("9999")) {
throw new NewException("此賬號非法！！");
}
// RequestContext rc =new RequestContext(req);
// rc.getMessage("hello");
System.out.println(222);
System.out.println(user.getId());
System.out.println(user.getPsd());
System.out.println();
model.addAttribute("userid", user.getId());
model.addAttribute("userpsd", user.getPsd());
System.out.println("getBrithday:"+user.getDate());
model.addAttribute("date", user.getDate());
return "mysuccess";

}

}

2.2自定義異常類的實現

public class NewException extends Exception {

/**
*
*/
private static final long serialVersionUID = 7856526306432864622L;

public NewException() {

}
public NewException(String mes) {
super(mes);
}

}

2.3攔截器類的實現

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.springframework.web.servlet.HandlerInterceptor;
import org.springframework.web.servlet.ModelAndView;

public class MyInterceptor implements HandlerInterceptor {

@Override
public void afterCompletion(HttpServletRequest arg0, HttpServletResponse arg1, Object arg2, Exception arg3)
throws Exception {
System.out.println("create afterCompletion=============");
}

@Override
public void postHandle(HttpServletRequest arg0, HttpServletResponse arg1, Object arg2, ModelAndView arg3)
throws Exception {
System.out.println("create postHandle=============");

}

@Override
public boolean preHandle(HttpServletRequest arg0, HttpServletResponse arg1, Object arg2) throws Exception {
System.out.println("create preHandle=============");
return true;
}

}

web.xml基本servlet配置

<servlet>
<servlet-name>mysmvc</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:*servlet.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>mysmvc</servlet-name>
<url-pattern>*.action</url-pattern>
</servlet-mapping>

使用配置文件設置編碼格式

<filter>
<filter-name>characterEncodingFilter</filter-name>
<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
<init-param>
<param-name>encoding</param-name>
<param-value>UTF-8</param-value>
</init-param>
<init-param>
<param-name>forceEncoding</param-name>
<param-value>true</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>characterEncodingFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
