這里先描述一下我自己的問題
我是學習ssm的初期，然后也是跟著網上的教程一步步走，但就是到了設計controller的時候出了錯誤，反復對比之后和網課的代碼可以說是除了一些包名不一樣，其他的是一摸一樣，在網上找了很多的帖子，都是說是組態檔沒有配好，要不就是沒有掃描包，要不就是地址錯了，但是我的都是對了，但是怎么測驗都是不對，但停了大概一下午之后居然可以用了，一臉懵
貼一下我寫的controller
package mycode.controller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
@Controller
public class mycontroller {
@RequestMapping("/test")
public String test()
{
return "test";
}
}
