Question

我正在使用Netbeans启动一个将在Glassfish中运行的新应用程序。

我使用Netbeans向导使用maven-archetype-webapp创建一个新的项目，并将我的所有类放在src->main->resources和我的JSP文件下src->main->webapp

这是我的web.xml：

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

<web-app xmlns="http://java.sun.com/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
         version="3.0">
    <display-name>My Applicaton Name</display-name>
    <servlet>
      <servlet-name>Access</servlet-name>
      <servlet-class>com.company.department.controller.UserController</servlet-class>
    </servlet>
    <servlet-mapping>
        <servlet-name>Access</servlet-name>
        <url-pattern>/Access</url-pattern>
    </servlet-mapping>

</web-app>

这是pom.xml：

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">
  <modelVersion>4.0.0</modelVersion>
  <groupId>com.mycompany</groupId>
  <artifactId>MyApp</artifactId>
  <packaging>war</packaging>

      <groupId>com.google.code.gson</groupId>
      <artifactId>gson</artifactId>

    </dependency>
    <dependency>
      <groupId>com.liferay</groupId>
      <artifactId>org.apache.commons.fileupload</artifactId>
      <version>1.2.2.LIFERAY-PATCHED-1</version>
    </dependency>
    <dependency>
      <groupId>org.json</groupId>
      <artifactId>json</artifactId>
      <version>20141113</version>
    </dependency>
    <dependency>
      <groupId>javax</groupId>
      <artifactId>javaee-web-api</artifactId>
      <version>7.0</version>
      <type>jar</type>
    </dependency>
  </dependencies>
    <build>
        <finalName>MyApp</finalName>
    </build>
</project>

当我在本地主机中运行时，我得到java.lang.ClassNotFoundException: com.company.department.controller.UserController

我是Maven的新手，所以我的错误在哪里？

我在SO中发现了一些类似的问题，但没有一个解决方案可以解决问题，而且大多数解决方案都是针对Eclipse的，并且在NetBeans中显然存在一些差异。

这是您的maven pom文件的片段。确保以下内容符合规定。

<properties>
   <endorsed.dir>${project.build.directory}/endorsed</endorsed.dir>
</properties>

<dependency>
    <groupId>javax</groupId>
    <artifactId>javaee-api</artifactId>
    <version>7.0</version>
    <scope>provided</scope>
</dependency>

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-dependency-plugin</artifactId>
    <version>2.1</version>
    <executions>
        <execution>
            <phase>validate</phase>
            <goals>
                <goal>copy</goal>
            </goals>
            <configuration>
                <outputDirectory>${endorsed.dir}</outputDirectory>
                <silent>true</silent>
                <artifactItems>
                    <artifactItem>
                        <groupId>javax</groupId>
                        <artifactId>javaee-endorsed-api</artifactId>
                        <version>7.0</version>
                        <type>jar</type>
                    </artifactItem>
                </artifactItems>
            </configuration>
        </execution>
    </executions>
</plugin>

使用maven-archetype-webapp创建的项目未找到servlet
