Java HTTP状态404。请求的源不可用

我对java和spring还是新手，目前我正在尝试将/buku/映射到my home.jsp，但它似乎不起作用

HomeController.java

home.jsp

web.xml

book-servlet.xml

我运行我的tomcat服务器并试图访问localhost:8080/buku/但它不起作用，请继续向我提供HTTP状态404-/buku/error

尝试添加book-servlet.xml以扫描控制器

      <property name="prefix" value="/WEB-INF/jsp/" />
      <property name="suffix" value=".jsp" />
   </bean>

</beans>

别忘了添加mvc名称空间

更新：我还注意到您没有指定请求方法。使用@RequestMappingvalue=/，method=RequestMethod重新调用@RequestMapping/。获取并尝试删除方法-home上方的RequestMapping注释？

是否要将/book/home映射到home.jsp？ 我认为您打算将/book/home路径映射到HomeController的home方法。。。然后试试下面的方法

@Controller
public class HomeController {

    private static Logger logger =Logger.getLogger(HomeController.class);

    @RequestMapping("book/home")
    public String home(ModelMap model){

        model.addAttribute("message", "Hello Spring MVC Framework!");
        return "home";
    }
}

---

现在，当您点击URL:localhost:8080/buku/book/home时，应该会显示home.jsp

启动web服务器时是否显示任何错误？因为你甚至不能访问project base根路径。也许你应该下载其他人的项目。看看他们之间的不同。这是最好的方法。很抱歉，我的意思是将“/buku/”映射到主页。jsp@jourpool-您是否尝试过URL:localhost:8080/buku谢谢您的回复，但仍然无法解决问题hmmm。。真奇怪。您有安全配置吗？尝试暂时删除web.xml中的安全筛选器，以查看它是否影响对路径/的访问。仍然不影响结果：/
