SpringMVC无法在Netbeans 8.2（maven build）中工作

标签： java spring maven spring-mvc netbeans-8

我是J2EE和Spring框架的新手。 我只是想开始在使用Maven的Netbeans v.8.2中使用这个框架，但是当我将Spring添加到组合中时，它甚至不会部署在GlassFish 4上。

我做了：

  

档案＆gt;新项目＆gt; Maven项目＆gt;网络应用程序

因为我想在第二时间添加Spring。

然后我在/ WEB-INF中添加了一个 spring-conf.xml 文件来配置Spring：

<?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>

这是我的部署描述符：

<?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">

    <!-- declaration of dispatcher servlet (Single servlet of Spring MVC) -->    
    <servlet>
       <servlet-name>dispatcher</servlet-name>
       <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
       <init-param>
          <param-name>contextConfigLocation</param-name>
          <param-value>/WEB-INF/spring-conf.xml</param-value>
       </init-param>
       <load-on-startup>1</load-on-startup>
    </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>

这是我的 pom.xml 文件，其中所有依赖项都已正确下载：

这是我的控制器：

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";
   }
}

我还附上了项目树的截图。 enter image description here

它甚至没有部署，这是错误：

  

严重：加载应用时出现异常

     

严重：上下文/ MySpringMVCExample

的取消部署失败      

Grave：加载应用程序时出现异常：java.lang.IllegalStateException：ContainerBase.addChild：start：org.apache.catalina.LifecycleException：org.apache.catalina.LifecycleException：org.xml.sax.SAXParseException; lineNumber：11; columnNumber：60;

那么，我错过了什么？谢谢！

答案 0 :(得分：2)

按如下方式调整 spring-conf.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"
        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>

此外，建议从pom文件中删除以下内容：

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

并在web.xml中修改您的请求映射，如下所示： <url-pattern>/*</url-pattern>
