SpringMVC在Netbeans 8.2中不工作（maven build）

我是J2EE和Spring框架的新手。我只是想開始採用使用Maven Netbeans中v.8.2這個框架，但是當我增加了Spring的組合，它甚至不部署在GlassFish 4SpringMVC在Netbeans 8.2中不工作（maven build）

我做：

File > new Project > Maven project > Web Application

，因爲我想在第二時間加入Spring。

然後我添加了一個彈簧conf.xml中文件configurate春，在/ WEB-INF：

<?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" 
     xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd 
     http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.0.xsd 
     http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsd"> 

    <context:component-scan base-package="alex.mawashi" /> 
    <mvc:annotation-driven /> 

</beans>

這是我部署描述符：

<?xml version="1.0" encoding="UTF-8"?> 
<web-app 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" 
    version="3.1">

      <param-value>/WEB-INF/spring-conf.xml</param-value> 
     </init-param>

    </servlet> 

    <!-- servlet-mapping of dispatcher servlet (Single servlet of Spring MVC) --> 
    <servlet-mapping> 
     <servlet-name>dispatcher</servlet-name> 
     <url-pattern>/spring-mvc/*</url-pattern> 
    </servlet-mapping> 
    <!-- end of servlet-mapping of dispatcher servlet (Single servlet of Spring MVC --> 
</web-app>

這是我的pom.xml文件，其中所有依賴關係已正確下載：

這是我的控制器：

package alex.mawashi.myspringmvcexample; 

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

@Controller 
public class SpringFirstController { 

    @RequestMapping(value = "/gimmeResponseBody") 
    @ResponseBody 
    public String sayHello() { 
     return "<p> Ciao! Questa risposta è direttamente ottenuta con il @ResponseBody! </p>"; 
    } 

    @RequestMapping(value = "/") 
    @ResponseBody 
    public String kimoNO() { 
     return "jspPage"; 
    } 
}

我附上我的項目樹的屏幕截圖也。

，它甚至沒有部署，這是錯誤：

Grave: Exception while loading the app

Grave: Undeployment failed for context /MySpringMVCExample

Grave: Exception while loading the app : java.lang.IllegalStateException: ContainerBase.addChild: start: org.apache.catalina.LifecycleException: org.apache.catalina.LifecycleException: org.xml.sax.SAXParseException; lineNumber: 11; columnNumber: 60; The prefix "context" for the element "context:component-scan" is not associated.

那麼，我缺少什麼？謝謝！

調整你的彈簧conf.xml中如下：

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


<context:component-scan base-package="alex.mawashi" /> 
    <mvc:annotation-driven /> 

</beans>

另外，建議刪除從POM文件如下：

<exclusions> 
    <exclusion> 
     <groupId>org.springframework</groupId> 
     <artifactId>spring-web</artifactId> 
    </exclusion> 
</exclusions>

和修改您的請求映射web.xml是這樣的： <url-pattern>/*</url-pattern>

謝謝，完成但現在這是錯誤：Grave：Exception in loadin g app：java.lang.IllegalStateException：ContainerBase.addChild：start：org.apache.catalina.LifecycleException：org.apache.catalina.LifecycleException：org.xml.sax.SAXParseException; lineNumber：17; columnNumber：60; cvc-complex-type.2.4.c：相應的快速字符是嚴格的，但不可能找到元素「context：component-scan」的聲明。 –

你能確保XSD文件版本匹配嗎？在我的例子中，我使用的是3.0，但也許你正在使用更新的例如4.0。這也會導致錯誤。 – SaWo

我已經試過了4.0而不是3.0，結果很不幸 –
