我有一个带注释的Controller类:
@Controller
public class MainController {
@RequestMapping("/test")
public ModelAndView testHandler(){
ModelAndView mav = new ModelAndView();
mav.setViewName("testView");
mav.addObject("message", "test");
return mav;
}
}
项目编译没有错误,但是当我运行它并点击http://.aggengine.com//test我得到404.我的映射是错误的还是我的URI?
答案 0 :(得分:3)
我想你忘记为你的控制器创建一个<bean>
。
<mvc:annotation-driven/>
只需启用支持,即在创建bean时读取bean的注释。
E.g。要注册您的控制器:
<bean id="mainController" class="my.package.MainController"/>
或者您可以启用自动类路径扫描,但这会导致appengine的性能问题,因为它很慢(并且每次应用程序冷启动时都会发生)
要启用类路径扫描,请将上下文命名空间添加到<beans>
并添加:
<context:component-scan base-package="my.package"/>
