I create e-mails from templates via Velocity in a Spring Web Application. Now I need to HTML escape SOME of the values. I found the Velocity Escape Tool. But I did not get the configuration working.
我在Spring Web应用程序中通过Velocity从模板创建电子邮件。现在我需要HTML转义一些值。我找到了速度逃逸工具。但是我没有让配置工作。
What I have tryed so fare is (spring applicationContext.xml):
我所查询的so fare (spring applicationContext.xml):
<bean id="velocityEngine" class="org.springframework.ui.velocity.VelocityEngineFactoryBean">
<property name="resourceLoaderPath" value="classpath:/velocity/emailTemplates" />
<property name="preferFileSystemAccess" value="false" />
<property name="overrideLogging" value="true" />
<property name="velocityProperties">
<util:properties>
<prop key="input.encoding">UTF-8</prop>
<prop key="output.encoding">UTF-8</prop>
<prop key="tools.toolbox">application</prop>
<prop key="tools.application.esc">org.apache.velocity.tools.generic.EscapeTool</prop>
</util:properties>
</property>
</bean>
Template (htmlEscapeTest.vm):
模板(htmlEscapeTest.vm):
with escape: $esc.html($needEscape)
TestCase:
TestCase:
@Test
public void testHtmlEscapingSupport() {
final String needEscape = "<test>";
ModelMap model = new ModelMap();
model.addAttribute("needEscape", needEscape);
String result = VelocityEngineUtils.mergeTemplateIntoString(velocityEngine, HTML_ESCAPING_TEMPLATE_FILE, model);
assertThat(result, StringContains.containsString("<test>"));
}
But the Test failed, ...got: "with escape: $esc.html($needEscape)"
但是测试失败了,……了:“逃避:$ esc.html(needEscape美元)”
Can anybody give me a hint what I am doing wrong?
有人能告诉我我做错了什么吗?
If I add new EscapeTool()
explicite in the test:
如果我在测试中添加新的EscapeTool()说明:
VelocityContext velocityContext = new VelocityContext(model);
velocityContext.put("esc", new EscapeTool());
StringWriter writer = new StringWriter();
velocityEngine.mergeTemplate(HTML_ESCAPING_TEMPLATE_FILE, velocityContext, writer);
String result = writer.toString();
then it is working. But as far as I understand the documentation, the tools should be configured once in the properties file.
然后工作。但就我对文档的理解而言,工具应该在属性文件中配置一次。
I am using Velocity Engine 1.7 and Velocity Tools 2.0.
我使用的是Velocity Engine 1.7和Velocity Tools 2.0。

You can not configure the Tools directly in the VelocityEngine. What you do instead, is that when you use the VelocityEngineUtils that you pass any Tools within the model map:
您不能直接在VelocityEngine中配置工具。相反,当您使用VelocityEngineUtils时,您可以在模型映射中传递任何工具:
ModelMap model = new ModelMap();
model.put("esc", new EscapeTool());
VelocityEngineUtils.mergeTemplateIntoString(
velocityEngine, "template.vm", "UTF-8", model)
Or if you use the VelocityEngine directly you could do:
或者你可以直接使用VelocityEngine:
VelocityContext velocityContext = new VelocityContext(model);
velocityEngine.mergeTemplate(templateLocation, encoding, velocityContext, writer);

警告:我是基于一段时间前的模糊记忆。里程可能有所不同。
Some of the Velocity documentation should be read from the perspective of "how do I use this in a VelocityView
?" If you want to use the same features directly from java code, then you need to change a few details. In this case, I believe that you're not creating the Context
properly. Try to follow the standalone example here, making sure that you "ask [the ToolManager] to create a context for you":
应该从“如何在VelocityView中使用它”的角度来阅读一些Velocity文档。如果您想直接从java代码中使用相同的特性,那么您需要更改一些细节。在这种情况下,我认为您没有正确地创建上下文。试着遵循这里的独立示例,确保“请[工具管理器]为您创建上下文”:
ToolManager manager = ...
Context context = manager.createContext();
Something similar probably is done under the covers for you if you use VelocityView
.
如果你使用VelocityView,类似的东西很可能是在你的掩护下做的。

Here's some code that I just got working. I found the standard tools are set up automatically by the ToolManager.
这是我刚开始使用的一些代码。我发现工具管理器会自动设置标准工具。
@Autowired
private VelocityEngine velocityEngine;
public void createHtml(String templateLocation, Map<String, Object> model) throws Exception {
ToolManager toolManager = new ToolManager();
ToolContext toolContext = toolManager.createContext();
VelocityContext velocityContext = new VelocityContext(model, toolContext);
StringWriter resultWriter = new StringWriter();
velocityEngine.mergeTemplate(templateLocation, "UTF-8", velocityContext, resultWriter);
String html = resultWriter.toString();
// use the HTML here
}
And my template has this
我的模板是这样的
<p>Dear $esc.html($customer.firstname)</p>

- Add velocity tool maven dependency in pom or add jar in class path.
- 在pom中添加velocity工具maven依赖项,或者在类路径中添加jar。
-
Add escape tool object in velocity context.
在velocity上下文中添加escape工具对象。
[ context.put("escapeTool",new EscapeTool()) ]
