org.springframework.web.servlet.DispatcherServlet noHandlerFound

访问http://api:8080/users这404级的时候，我得到这个错误，我得到这个错误在我的控制台：当我访问http://localhost:8080/api/usersorg.springframework.web.servlet.DispatcherServlet noHandlerFound

Sep 23, 2014 5:57:52 PM org.springframework.web.servlet.DispatcherServlet noHandlerFound 
WARNING: No mapping found for HTTP request with URI [/users] in DispatcherServlet with name 'dispatcher'

我在浏览器中得到了404，但在我的控制台没有错误

的applicationContext.xml

<?xml version="1.0" encoding="UTF-8"?> 
<beans xmlns="http://www.springframework.org/schema/beans" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    <context:component-scan base-package="com.api"/>

调度-servlet.xml中：

<?xml version="1.0" encoding="UTF-8"?>

      http://www.springframework.org/schema/context/spring-context.xsd 
    "> 

    <context:component-scan base-package="com.api"/>  
</beans>

的web.xml：

<?xml version="1.0" encoding="UTF-8"?> 
<web-app version="3.1" xmlns="http://xmlns.jcp.org/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd">

    <servlet-mapping> 
    <servlet-name>dispatcher</servlet-name> 
    <url-pattern>/</url-pattern> 
    </servlet-mapping> 
</web-app>

Users.java：

package com.api; 

import org.springframework.beans.factory.annotation.Autowired; 
import org.springframework.stereotype.Controller; 
import org.springframework.web.bind.annotation.RequestMapping; 
import org.springframework.web.bind.annotation.RequestMethod; 
import org.springframework.web.bind.annotation.RestController; 

@RequestMapping("/users") 
public class Users { 
    @Autowired 
    public Users() { 

    } 

    @RequestMapping(method = RequestMethod.GET) 
    public void getUser() { 
     System.out.println("\nhere\n"); 
    } 
}

如果任何人有任何线索，我会非常感激。我查阅了几个与我得到的错误相同的问题，但常见的解决方案是添加已有的，所以我不知道还有什么可以做。谢谢。

编辑：我刚刚更新了所有的代码，以最新的参考文档是什么，我仍然得到同样的错误。编辑：更新显示我目前的档案状态。

阅读Spring参考文档，你与有关Spring MVC的新配置混合在一起的旧配置。你的代码是错误的。 – 2014-09-23 22:16:24

你能更具体一点吗？ – wonza 2014-09-23 22:22:58

我用参考文档中的最新代码更新了我的问题，但仍然收到相同的错误。 – wonza 2014-09-23 23:08:11

改变你的web.xml中

<?xml version="1.0" encoding="UTF-8"?> 
<web-app version="3.1" xmlns="http://xmlns.jcp.org/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"> 

    <servlet> 
    <servlet-name>dispatcher</servlet-name> 
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> 
    <load-on-startup>2</load-on-startup> 
    </servlet> 
    <servlet-mapping> 
    <servlet-name>dispatcher</servlet-name> 
    <url-pattern>/</url-pattern> 
    </servlet-mapping> 
</web-app>

和调度 - servlet.xml中以

<?xml version="1.0" encoding="UTF-8"?> 
<beans xmlns="http://www.springframework.org/schema/beans" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xmlns:p="http://www.springframework.org/schema/p" 
    xmlns:aop="http://www.springframework.org/schema/aop" 
    xmlns:tx="http://www.springframework.org/schema/tx" 
    xmlns:context="http://www.springframework.org/schema/context" 
    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/aop 
    http://www.springframework.org/schema/aop/spring-aop-3.0.xsd 
    http://www.springframework.org/schema/mvc 
    http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd"> 

    <context:component-scan base-package="com.api"/> 
</beans>

你不需要的applicationContext.xml为您的代码运行

没有什么我试过，但我不得不添加：http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd让它工作，但我仍然得到相同的错误 – wonza 2014-09-24 00:57:04

你得到了什么错误？ – 2014-09-24 05:05:33

它显示在我的问题的顶部 – wonza 2014-09-24 14:10:39

需要添加以下行的弹簧context.xml的

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

Note: property prefix and suffix need to modify based on your application like .jsp if you are using jsp files.

A common mistake is this 
    Make sure the group id in pom.xml is the parent of that mentioned in 
    </context:component-scan> 

    For Example 
    If Group Id-com.cavesofprogramming.spring.web then 
    <context:component-scan base- package="com.cavesofprogramming.spring.web.controllers"> 

    The effect is that the controller is not found in the maven build and 
    as a result the mapping not done to the correct jsp.
