我在注释处理器上使用 Velocity Escape 工具时遇到问题。首先，我让注释处理器单独以速度正常工作，所以我知道设置是正确的。当使用带有转义字符的字符串时，我创建的源开始出现问题。所以我上网找到了 Velocity 的 EscapeTool。可以这么说，文档对于配置不是很好。
我找到了一些代码，但不记得在哪里，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。
您可以找到代码 here(在存储库中评论)。
如果有兴趣，可以从 https://javydreamercsw@bitbucket.org/javydreamercsw/jwrestling 查看源代码。
非常欢迎任何帮助!
更新: 以下是velocity-tools.xml 的内容，它是velocity-tool jar 中找到的副本:

最佳答案
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));
}
