如何使用mule过滤器过滤字符串中的通配符

Question

我有价值/ asdf。我想分开＆＃39; /＆＃39;来自字符串。

如何使用mule过滤器实现这一目标？

Answer 1

不确定我是否正确理解了您的问题，但是要定义一个匹配＆＃34; asdf＆＃34;的通配符过滤器。和＆＃34; / asdf＆＃34;在Mule中你只需要<wildcard-filter pattern="*asdf"/>

Answer 2

这应该有效：

    <flow name="test">
        <http:inbound-endpoint exchange-pattern="request-response" host="0.0.0.0" port="8081" path="in"/>
        <scripting:transformer>
            <scripting:script engine="Groovy"><![CDATA[
                def p = java.util.regex.Pattern.compile("^/(.*)")
                def m = p.matcher(message.getPayload())
                if (!m.find()) throw new IllegalArgumentException('Message does not start with /')
                return m.group(1)
            ]]></scripting:script>
        </scripting:transformer>
</flow>
