1、错误描述
今天使用正则表达式验证密码的时候,报了错误
java.util.regex.PatternSyntaxException: Incorrect Unicode property near index 32:
错误具体输出日志如下:
04-28 12:49:46.254 2224-2224/com.xtc.watch E/AndroidRuntime: FATAL EXCEPTION: main
Process: com.xtc.watch, PID: 2224
java.util.regex.PatternSyntaxException: Incorrect Unicode property near index 32:
^(?![0-9]+$)(?![a-zA-Z]+$)(?!\pP+$)(\S){6,16}$
^
at java.util.regex.Pattern.compileImpl(Native Method)
at java.util.regex.Pattern.compile(Pattern.java:411)
at java.util.regex.Pattern.<init>(Pattern.java:394)
at java.util.regex.Pattern.matches(Pattern.java:424)
at java.lang.String.matches(String.java:1334)
该正则表达式的代码如下所示:
String regex = "^(?![0-9]+$)(?![a-zA-Z]+$)(?!\\pP+$)(\\S){6,16}$";
2、解决方法
通过百度,查到一篇文章解决了该bug。该文章链接地址是:
http://stackoverflow.com/questions/22665156/incorrect-unicode-property-near-index
尝试把 \pP改成\p{P}
即将上面报错的错误正则表达式
String regex = "^(?![0-9]+$)(?![a-zA-Z]+$)(?!\\pP+$)(\\S){6,16}$";
变成正确的正则表达式
String regex = "^(?![0-9]+$)(?![a-zA-Z]+$)(?!\\p{P}+$)(\\S){6,16}$";
这样就解决了该bug。
