使用CXF时如何处理WS输出中的无效字符？ [英] How to deal with invalid characters in a WS output when using CXF?

问题描述

我正在使用Spring，CXF和Hibernate构建一个WebService，它对我有只读访问权的外部数据库执行搜索查询。

I'm using Spring, CXF and Hibernate to build a WebService that perform search queries on a foreign database that I have read-only access.

问题是数据库中的某些条目在文本字段中有奇怪的字符（0x2），并且它似乎用于处理/序列化从Hibernate会话返回的对象的CXF或库（Aegis？）无法处理它：

The problem is that some entries in the database have strange characters (0x2) in text fields, and it seems that CXF or the library (Aegis?) that it uses to process/serialize the objects returned from the Hibernate session can't deal with it:

org.apache.cxf.aegis.DatabindingException: Error writing document.. Nested exception is com.ctc.wstx.exc.WstxIOException: Invalid white space character (0x2) in text to output (in xml 1.1, could output as a character entity)

我如何解决这个问题？
理想情况下，我可以删除这些字符，因为它们对我的输出无关...
谢谢！

How do I get around that? Ideally, I could just remove those characters, since they don't matter for my output... Thanks!

推荐答案

/**
* From xml spec valid chars:<br>
* #x9 | #xA | #xD | [#x20-#xD7FF] | [#xE000-#xFFFD] | [#x10000-#x10FFFF]<br>
* any Unicode character, excluding the surrogate blocks, FFFE, and FFFF.<br>
* @param text The String to clean
* @param replacement The string to be substituted for each match
* @return The resulting String
*/
public static String CleanInvalidXmlChars(String text, String replacement) {
    String re = "[^\\x09\\x0A\\x0D\\x20-\\xD7FF\\xE000-\\xFFFD\\x10000-x10FFFF]";
    return text.replaceAll(re, replacement);
}
