我在调用控制器时遇到问题。服务器返回没有找到处理程序方法错误。以下是我的web.xml:

以下是我的控制器
package com.et.til.mynewsletters.admin.controller;
import javax.servlet.http.HttpServletRequest;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.ui.ModelMap;
import org.springframework.validation.BindingResult;
import org.springframework.validation.annotation.Validated;
import org.springframework.web.bind.annotation.ModelAttribute;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.ResponseBody;
@Controller
public class LoginController {
@RequestMapping(value = "/hello", method = RequestMethod.GET)
@ResponseBody
public String hello(HttpServletRequest request) {
return "Hello";
}
}
尽管调度程序servlet中的url模式为“/”,但/ hello映射仍无法正常工作。 tomcat服务器返回未找到的Handler方法,并且tomcat日志中没有错误或异常。请帮帮我。

我的猜测是你将它部署在tomcat的子上下文中。例如,如果您的war文件被调用&#34; my-project.war&#34;,则需要在http://localhost:8080/my-project/hello

您可以尝试将<context:component-scan base-package="com.til.et" />
更正为<context:component-scan base-package="com.te.til" />
吗?
