这是我的包裹:

import java.util.Random;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
@Controller
public class MyDemoController {
private String[] quotes = {"To be or not to be -Shakespeare", "Spring is the nature's way of
saying 'let's party'-from someone","The time is always right to do what is right"};
@RequestMapping(value="/getQuote")
public String getRandomQuote(Model model) {
int rand = new Random().nextInt(quotes.length); String randomQuote =quotes[rand];
model.addAttribute("randomQuote", randomQuote);
return "quote"; }
@RequestMapping(value="/createAccount")
public String createAccount() {
return "createAccount";
}
}

- 我获取了 localhost:8080/springMVCDemo/getQuote.html 的网页
但是我没有看到以下页面 本地主机:8080/springMVCDemo/createAccount.html
任何线索都会有所帮助
最佳答案
错误背后的原因是 Tomcat，我们需要构建并重新发布才能正确加载所有页面
