我在注释处理器上使用 Velocity Escape 工具时遇到问题。首先，我让 Annotation 处理器单独使用速度工作正常，所以我知道设置是正确的。在使用带有转义字符的字符串时，我开始遇到我创建的源的问题。所以我在网上找到了有关Velocity 的EscapeTool。可以说文档对配置不是很好。

我能够找到一些代码，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());

但我在配置部分遇到以下错误：

我认为这是一个依赖问题，但依赖关系如下：

        <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>

org.apache.velocity.tools.config.Data 包含在velocity-tools jar 中。

你可以在这里找到代码（在 repo 上评论）。

如果有兴趣，可以从https://javydreamercsw@bitbucket.org/javydreamercsw/jwrestling查看源代码。

任何帮助都非常受欢迎！

更新： 以下是velocity-tools.xml 的内容，它是velocity-tool jar 中的副本：

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));
        }

尝试

 new ToolManager(false,false)
