spring mvc HTTP狀態404基本啓動

我無法弄清楚這段代碼中的問題。我沒有得到主頁，也沒有在控制檯中顯示錯誤。spring mvc HTTP狀態404基本啓動

的web.xml：

<web-app> 
    <display-name>Myapp</display-name> 
    <servlet> 
     <servlet-name>dispatcher</servlet-name> 
     <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> 
    </servlet> 
    <servlet-mapping> 
     <servlet-name>dispatcher</servlet-name> 
     <url-pattern>*.do</url-pattern> 
    </servlet-mapping> 

</web-app>

調度-servlet.xml中：

<beans xmlns="http://www.springframework.org/schema/beans" 
    xmlns:context="http://www.springframework.org/schema/context" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:mvc="http://www.springframework.org/schema/mvc" 
    xsi:schemaLocation=" 
    http://www.springframework.org/schema/beans  
    http://www.springframework.org/schema/beans/spring-beans-3.0.xsd 
    http://www.springframework.org/schema/mvc 
     http://www.springframework.org/schema/mvc/spring-mvc.xsd 
    http://www.springframework.org/schema/context 
    http://www.springframework.org/schema/context/spring-context-3.0.xsd"> 
    <mvc:annotation-driven /> 
    <context:component-scan base-package="com.sim.market.controller" /> 

    <bean 
     class="org.springframework.web.servlet.view.InternalResourceViewResolver"> 
     <property name="prefix" value="/WEB-INF/jsp/" /> 
     <property name="suffix" value=".jsp" /> 
    </bean> 

</beans>

首頁控制器：

package com.sim.market.controller; 

import org.springframework.stereotype.Controller; 
import org.springframework.web.bind.annotation.RequestMapping; 

@Controller 
@RequestMapping("/home") 
public class HomeController { 

    public String showHome(){ 
     System.out.println("calloing"); 
     return "home"; 
    } 
}

在控制檯上沒有錯誤，但在瀏覽器錯誤是

HTTP Status 404 - 

type Status report

您使用什麼URL訪問您的資源？你的Web應用程序是否正確地部署在你的Web服務器上，並且你的Web服務器是否正常運行？ –

http：// localhost：8080/MyApp/home.do – coreJavare

我沒有看到@coreJavare調用的URL。刪除我的答案。 – Prasad

註釋與@RequestMapping您showHome()的方法來確定它作爲處理程序。沒有它，你的控制器沒有處理方法，因此沒有處理請求。

很顯然，您會在@RequestMapping上添加限制，例如處理哪些HTTP方法，可能包含哪些標頭，甚至專門處理應該處理的路徑。

剛做完添加相同： \t @RequestMapping（方法= RequestMethod.GET），但還是同樣的錯誤 – coreJavare

@core是應用程序部署？日誌顯示了什麼？ –

請檢查問題，因爲我已經添加log – coreJavare

您需要爲您的請求映射。

@RequestMapping (value = "/showhome", method = {RequestMethod.GET, RequestMethod.POST}) 
public String showHome(ModelMap model, HttpServletRequest request) { }

就像那樣。

試過這其中也但還是同樣的錯誤 – coreJavare

你的要求應該是localhost /項目名/家庭/ showHome –

那麼你應該在web.xml中添加此

<welcome-file-list> 
     <welcome-file>index.jsp</welcome-file> 
    </welcome-file-list>

添加該代碼段

的index.jsp

<meta HTTP-EQUIV="REFRESH" content="0; url=${pageContext.request.contextPath}/home.do">

每次我提出申請時發現，這是一個很好的選擇，在Spring MVC

沒有它，這也沒有奏效。 – coreJavare

這個改變會是什麼？ –

首先它將被重定向到index.jsp頁面，該頁面將刷新並重定向到您指定的URL ...此URl應該是您要執行的控制器方法的映射 – tarkikshah
