org.springframework.web.servlet.PageNotFound：1108

Question

我嘗試解決了這個問題，我在計算器中遇到但沒有工作對我來說

所有的解決方案，這是我的web.xml：

<?xml version="1.0" encoding="UTF-8"?> 
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xmlns="http://java.sun.com/xml/ns/javaee" 
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" 
    version="2.5"> 

    <servlet> 
     <servlet-name>appServlet</servlet-name> 
     <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> 
     <init-param> 
      <param-name>contextConfigLocation</param-name> 
      <param-value>/WEB-INF/servlet-context.xml</param-value> 
     </init-param> 
     <load-on-startup>1</load-on-startup> 
    </servlet> 

    <servlet-mapping> 
     <servlet-name>appServlet</servlet-name> 
     <url-pattern>/</url-pattern> 
    </servlet-mapping> 


</web-app> 

這是我的servlet上下文的XML：

<!-- Enable @Controller annotation support --> 
     <mvc:annotation-driven /> 

     <!-- Esta etiqueta es para mapear carpetas dentro de src/main/webapp 
      de lo contrario el servidor no las reconoceria

      <property name="packagesToScan"> 
       <array>

     </bean> 

     <!-- Activates annotation based transaction management --> 
     <tx:annotation-driven transaction-manager="transactionManager" /> 
    </beans> 

控制器：

@Controller 
public class UsuarioController { 

    @Autowired UsuarioDAOImpl usuarioDAO; 

    @RequestMapping(value = "lista", method = RequestMethod.GET) 
    public String testReporte(Model model) { 

     try { 
      System.out.println("Entre"); 
      List<Usuario> lista = usuarioDAO.encontrarTodosUsuarios(); 
      model.addAttribute("lista", lista); 

     } catch (Exception e) { 
      // TODO: handle exception 
      e.printStackTrace(); 
     } 

     return "index"; 
    } 

} 

我認爲這個問題出現在web.xml或servlet-context.xml中 我不知道我的應用程序發生了什麼，春天的其他應用程序永遠不會導致這個問題。

org.springframework.web.servlet.PageNotFound：1108 - 否的DispatcherServlet找到HTTP請求與URI [/ usuariosTest /]與名稱映射 'appServlet'

Answer 1

您可以爲「沒有提供所述請求映射/「即用於啓動網址。

將「/」url映射放入您的控制器中。您需要先將其部署到服務器上，然後啓動服務器，然後在瀏覽器中點擊應用程序URL。

@RequestMapping(value = "/", method = RequestMethod.GET) 
public String testReporte(Model model) { 

    try { 
     System.out.println("Entre"); 
     List<Usuario> lista = usuarioDAO.encontrarTodosUsuarios(); 
     model.addAttribute("lista", lista); 

    } catch (Exception e) { 
     // TODO: handle exception 
     e.printStackTrace(); 
    } 

    return "index"; 
}
