java - 在 PMD 中使用 JSP 自定义规则

Question

我需要一种在 Sonar 上使用的验证，它应该查看 XHTML 页面中的 JSF 元素，验证输入元素是否包含 ID 属性。 (例如:)

最初我尝试使用 PMD 来完成。正如我所见，PMD 可以解释 JSP 页面。这是对的吗？方法是实现基于 AbstractJspRule 的自定义规则。

目前的问题是 PMD 试图将 XHTML 页面解析为 Java 代码。它应该解释为 JSP 页面。

我的代码:
类:

public class TestXhtmlRule extends AbstractJspRule {

 @Override
 public Object visit(final ASTElement node, final Object data) {
      // ...
 }

 @Override
 public Object visit(final ASTAttribute node, final Object data) {
      // ...
 }

}

xml:

<ruleset name="Basic JSF rules" 
    xmlns="http://pmd.sourceforge.net/ruleset/2.0.0"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://pmd.sourceforge.net/ruleset/2.0.0 http://pmd.sourceforge.net/ruleset_2_0_0.xsd"
    xsi:noNamespaceSchemaLocation="http://pmd.sourceforge.net/ruleset_2_0_0.xsd">
    <include-pattern>**/*.xhtml</include-pattern>

<rule name="idsJSF" language="jsp"  
        message="..."
        class="pmd.rule.TestXhtmlRule">
        <description>
            ...
        </description>
        <priority>3</priority>

        <example>
        <![CDATA[
             <h:inputText id="itNome" label="Nome" value="#{pessoaBean.nome}" />;
        ]]>
        </example>
    </rule>
</ruleset>

日志错误:

我怎样才能让它发挥作用？
使用 checkstyle 而不是 PMD 验证此规则会更容易吗？

谢谢。

As I've seen PMD can interpret JSP pages. Is it correct?

是的，但前提是您拥有格式良好的 XHTML——您拥有。

How can I make it work?

问题甚至在 PMD 运行您的规则之前就已经发生了。它将文件(无论是 Java 还是 jsp 或其他任何文件)解析为 AST(抽象语法树)，然后针对它运行相关规则。您是否在运行 PMD 时传递了 -jsp 标志，如如何使用部分所述at the bottom of the PMD JSP page ？我的猜测是，您并非如此 PMD 将所有内容都视为 Java。
