Java中的Velocity EscapeTool

我在我的Annotation处理器上使用Velocity Escape工具时遇到了问题。首先，我让Annotation处理器单独使用Velocity时工作正常，所以我知道设置是正确的。当使用带有scape字符的字符串时，我开始对我创建的源代码产生问题。所以我在互联网上找到了关于Velocity的EscapeTool。让我们只说文档在配置方面不是很好。
我能找到一些代码，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());

但我在配置部分得到以下错误：

我认为这是一个依赖关系问题，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>

数据包含在velocity-tools jar中。
你可以找到代码here（在repo上注解）。
如果感兴趣，可以从https://javydreamercsw@bitbucket.org/javydreamercsw/jwrestling中检出源代码。
任何帮助都比欢迎！

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

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

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();

我在Sping Boot 中使用Velocity，并试图弄清楚上面的问题。我没有尝试上面的方法，因为我不需要每个工具，但只是想分享你可以从Velocity工具中添加一个特定的工具。
我的速度引擎配置

@Configuration
public class VelocityConfiguration {
    
    @Bean
    public VelocityEngine velocityEngine() throws IOException{
        VelocityEngineFactoryBean bean = new VelocityEngineFactoryBean();
        Properties velocityProperties = new Properties();
        velocityProperties.setProperty("runtime.log.invalid.references", "true");
        velocityProperties.setProperty("input.encoding", "UTF-8");
        velocityProperties.setProperty("runtime.log.invalid.references", "true");
        
        //for CLASS = template must be in /resources ONLY (under the <default package>
        velocityProperties.setProperty("resource.loader", "class");
        velocityProperties.setProperty("class.resource.loader.description", "Velocity Classpath Resource Loader");
        velocityProperties.setProperty("class.resource.loader.class", "org.apache.velocity.runtime.resource.loader.ClasspathResourceLoader");
        
        //enable inclusion of relative templates
        velocityProperties.setProperty("eventhandler.include.class", "org.apache.velocity.app.event.implement.IncludeRelativePath");
        
        bean.setVelocityProperties(velocityProperties);
                        
        return bean.createVelocityEngine();
    }

}

我只需要日期工具，所以我只添加了XML文件velocityContext.put（“date”，newComparisonDateTool（））中的类;

@Component
public class VelocityTemplateWriter {

    private final VelocityEngine velocityEngine;

    @Value("${vm.template.path}")
    private String apacheVMTemplatePath;

    @Autowired
    public VelocityTemplateWriter(@Qualifier("velocityEngine") VelocityEngine velocityEngine) {
        this.velocityEngine = velocityEngine;
    }

    public String write(Map<String, Object> data){
        VelocityContext velocityContext = new VelocityContext();
        velocityContext.put("output", data);
        velocityContext.put("date", new ComparisonDateTool());

        StringWriter stringWriter = new StringWriter();
        velocityEngine.mergeTemplate(apacheVMTemplatePath + "ParentResponse.vm", "UTF-8", velocityContext, stringWriter);

        String output = stringWriter.toString();

        return output;
    }
