来自Java的Velocity EscapeTool

Question

我在注释处理器上使用Velocity Escape工具时遇到了问题。首先，我让注释处理器单独使用velocity工作得很好，所以我知道设置是正确的。当使用带有scape字符的字符串时，我开始在创建的源代码中出现问题。所以我在网上找到了关于EscapeTool的Velocity。让我们只说，关于配置的文档不是很好。

我找到了一些代码，不记得在哪里，让我开始：

ToolManager velocityToolManager = new ToolManager();
velocityToolManager.configure("velocity-tools.xml");
VelocityContext vc =
           new VelocityContext(velocityToolManager.createContext());

但是在配置部分，我得到了以下错误：

我认为这是一个依赖关系问题，但依赖关系如下所示：

        <dependency>
            <groupId>org.apache.velocity</groupId>
            <artifactId>velocity</artifactId>
            <version>1.7</version>
            <type>jar</type>
        </dependency>
        <dependency>
            <groupId>org.apache.velocity</groupId>
            <artifactId>velocity-tools</artifactId>
            <version>2.0</version>
        </dependency>

velocity.tools.config.data包含在velocy-tools jar中。

任何帮助都是非常欢迎的！

更新：以下是velocity-tools.xml的内容，它是velocity-tooljar中的一个副本：

    <data type="number" key="TOOLS_VERSION" value="2.0"/>

XmlFactoryConfiguration factoryConfiguration = new XmlFactoryConfiguration("Default Tools");
        try {
            factoryConfiguration.read(new FileInputStream(new File(Thread.currentThread().getContextClassLoader().getResource("/").getFile(), TOOL_BOX_CONF_FILE)));
        } catch (IOException e) {
            e.printStackTrace();
        }
        ToolboxFactory factory = factoryConfiguration.createFactory();
        factory.configure(factoryConfiguration);
        toolContext = new ToolContext();
        for (String scope : Scope.values()) {
            toolContext.addToolbox(factory.createToolbox(scope));
        }
