我有一个具有两种方法的控制器类。假设“http://localhost:8080/SpringAOP1/welcome/two/aa”，一旦 URL 被击中，第一种类型必须执行其主体。这里 SpringAOP1 是我的项目，welcome 是控制器类名（带有注释设置），二是带有参数“aa”的函数名。第二种类型的函数需要由拦截器预先处理。因此，当 URL 被命中假设“http://localhost:8080/SpringAOP1/welcome/intercep/six/aa”时，必须调用拦截器。在这里，我将“intercep”参数与所有需要拦截器调用的第二类函数一起传递。
控制器类：-
@Controlle
@RequestMapping("/welcome")
public class HelloController {
@RequestMapping(method = RequestMethod.GET)
public String printWelcome1(ModelMap model) {
model.addAttribute("message", "Spring 3 MVC Hello World 1");
return "hello";
}
@RequestMapping( value="two/{name}", method = RequestMethod.GET)
public String printWelcome2(@PathVariable String name,ModelMap model) {
model.addAttribute("message", "Spring 3 MVC Hello World 2");
model.addAttribute("value", name);
return "hello";
}
@RequestMapping( value="intercep/six/{name}", method = RequestMethod.GET)
public String printWelcome6(@PathVariable String name,ModelMap model) {
model.addAttribute("message", "Spring 3 MVC Hello World 6");
model.addAttribute("value", name);
return "hello";
}

HijackBefore 方法
（这是被调用的拦截器类）
public class HijackBeforeMethod extends HandlerInterceptorAdapter {
public Boolean comp(String u,String p)
{
Map mMap = new HashMap();
mMap.put("aa", "bb");
mMap.put("mm", "nn");
mMap.put("xx", "yy");
Iterator iter = mMap.entrySet().iterator();
String k,v;
Boolean flg=false;
while (iter.hasNext())
{
Map.Entry mEntry = (Map.Entry) iter.next();
if(mEntry.getKey().equals(u) && mEntry.getValue().equals(p))
flg=true;
}
return flg;
}
public boolean preHandle(HttpServletRequest httpServletRequest,
HttpServletResponse httpServletResponse, Object o) throws Exception {
String u="aa";
String p="bb";
//System.out.println(" The username is--> "+u+" and pass is --> "+p);
Boolean ch=comp(u,p);
if(ch)
{
if(httpServletRequest.getMethod().equalsIgnoreCase("get")){
String uri = httpServletRequest.getRequestURI();
System.out.println("The method is GET :: "+ uri);
}
else
{
return false;
}
}
}
请帮我找到这个。我有很大的麻烦..
