java - request.getParameterMap() 锁

我是java程序员，java中取到页面所有的参数方式为： request.getParameterMap()，但是这个取得的Map不能存放值进去，除非

/**

解锁map
@param map2
@throws Exception
*/

void releaseLock(Map<String, String[]> map2) throws Exception {

   java.lang.reflect.Method method = map2.getClass().getMethod("setLocked",new Class[]{boolean.class});
   
   method.invoke(map2,new Object[]{new Boolean(false)});

}

解锁。那么，为什么会锁住呢？？有谁知道么?

FYI

As you've noted HttpServletRequest does not have a setParameter method. This is deliberate, since the class represents the request as it came from the client, and modifying the parameter would not represent that.
