我搭建一个Spring MVC 环境。controller中加上@Controller注解
[code="java"]
@Controller
public class Login {
private IUserService userService;
public IUserService getUserService() {
return userService;
}
public void setUserService(IUserService userService) {
this.userService = userService;
}
@RequestMapping("login.html")
public String login(HttpServletRequest request, HttpServletResponse response, ModelAndView view){
System.out.println("handle the login.html");
System.out.println(userService.getUserByCustId("000001031234").getUserMail());
return "index";
}
}
[/code]
在spring的配置文件中配置注解扫描等。同时配置
[code="java"]
[/code]
注入userService。
问题来了：
如果不加这个注入项目可以正常运行，如果加了这个注入。提示异常
[code="java"]
org.springframework.beans.factory.BeanCreationException:
Error creating bean with name 'org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping': Initialization of bean failed; nested exception is java.lang.IllegalStateException: Cannot map handler 'loginController' to URL path [/login.html]: There is already handler of type [class com.sdemo.controller.Login] mapped.
[/code]
请问该怎么办呢？问题出在哪里？注解和注入不能并存么？
