Tomcat 7中的ClassNotFoundException

提问于

我在使用Tomcat Web应用程序中的依赖项时遇到问题 . 我试过了：

  • 将.jar添加到WEB-INF / lib

  • 在$ CATALINA_HOME / conf / catalina.properties中添加路径

  • 在IntelliJ中的Tomcat配置中添加.jar

  • 将.jar添加到$ TOMCAT_HOME / lib

但是，在调用依赖项时，我得到相同的错误：

如果我从外部Tomcat调用依赖项，一切正常 .

java tomcat intellij-idea morphia

    您只需将其添加为IDEA项目定义的依赖项 . 如果您使用的是maven或gradle，请将依赖项添加到构建文件中 . 例如，对于maven，您可以将以下内容添加到 pom.xml 文件中：

    <dependency>
    <groupId>org.mongodb.morphia</groupId>
    <artifactId>morphia</artifactId>
    <version>0.109</version>
</dependency>

    如果您通过IDEA配置了项目：

    • 转到 File > Project Structure

    • 单击左侧“项目设置”部分中的“模块”链接 .

    • 选择使用依赖关系的模块 .

    • 单击“依赖关系”选项卡 .

    • 点击右侧的添加按钮
      enter image description here
      ，然后选择"Library"

    • 在"Choose Libraries"对话框中，单击"New Library..."按钮并从弹出列表中选择Java

    • 在File Browswer对话框中，选择库的JAR文件，或包含JAR文件的目录（它将在目录中添加所有JAR）或包含类的目录 .

    • 在文件选择器对话框中单击“确定”

    • 在"Configure Library"对话框中，为库指定适当的名称 . 如果需要，可以将源和javadoc添加到定义中 . （您也可以通过选择多个JAR在File Chooser表单中执行此操作.IDEA会自动确定它们是类，源还是Javadoc . ）

    • 在"Configure Library"对话框中单击“确定” .

    • 返回"Choose Libraries"对话框，应选择刚刚创建的库 . （如果没有，请选择它 . ）单击"Add Selected"按钮

    • 在“项目结构”对话框中单击“确定” .

    有关更多详细信息，请参阅“帮助指南”中的"Configuring Module Dependencies and Libraries"（也在web here上） .

    现在，当您通过IDEA Tomcat运行/调试配置将Web应用程序部署到Tomcat时，该库将与其余代码一起部署 . 有关详细信息，请参阅IDEA帮助指南（或web here）中的"Run/Debug Configuration: Tomcat"主题 .

    上面的错误意味着jar包含类org.mongodb.morphia.Morphia在类路径中不存在 . 因此，请确保在您的Web应用程序中's lib or tomcat' s lib包含包含上述类的jar . 我想你可以从here获得 jar .

    这是因为Morphia jar不属于你的输出war / jar . Eclipse或本地构建将它们作为类路径的一部分包含在内，但远程构建或自动/预定构建不会将它们视为类路径的一部分 .

    您可以使用插件包含相关的jar .

    将下面的代码段添加到您的pom的插件部分

    <plugin>
    <artifactId>maven-assembly-plugin</artifactId>
    <version>3.0.0</version>
    <configuration>
        <descriptorRefs>
            <descriptorRef>jar-with-dependencies</descriptorRef>
        </descriptorRefs>
    </configuration>
</plugin>
