打扰您,很抱歉。
对于Collections.sort方法中的判断条件不是很理解。判断相同之后,返回uri所在的索引位置。但是既然相同了,索引位置一定是0不是么?希望能详细解释一下。谢谢
关于
路由匹配器使用了正则去遍历路由列表,匹配合适的路由。当然我不认为这是最好的方法, 因为路由的量很大之后遍历的效率会降低,但这样是可以实现的,如果你有更好的方法可以告诉我 :)
private List<Route> routes = new ArrayList<Route>();
/**
* 根据path查找路由
* @param path 请求地址
* @return 返回查询到的路由
*/
public Route findRoute(String path) {
String cleanPath = parsePath(path);
List<Route> matchRoutes = new ArrayList<Route>();
for (Route route : this.routes) {
if (matchesPath(route.getPath(), cleanPath)) {
matchRoutes.add(route);
}
}
// 优先匹配原则
giveMatch(path, matchRoutes);
return matchRoutes.size() > 0 ? matchRoutes.get(0) : null;
}
使用map替换list存储Route,查找效率不就更高?
MarioContext
持有一个 ThreadLocal<MarioContext>
类型的属性 CONTEXT
。同时 MarioContext
中有 remove()
方法,但是这个 remove()
方法没有在任何地方被调用过,这样是不是容易造成内存泄漏?
