首先我这样做了 –
String str = "{\"hits\":[{\"links_count\":6,\"forum_count\":11}],\"totalHitCount\":1}";
Assert.assertTrue(str.matches("{\"hits\":[{\"links_count\":[0-9]{1,},\"forum_count \":11}],\"totalHitCount\":[0-9]{1,}}"),"Partnership message does not appear");
这让我跟着错误 –
Exception in thread "main" java.util.regex.PatternSyntaxException: Illegal repetition {"hits":[\{"links_count":[0-9]{1,"forum_count":11}],"totalHitCount":[0-9]{1,}}
然后我做了(逃脱“{”) –
String str = "\\{\"hits\":[\\{\"links_count\":6,\"forum_count\":11\\}],\"totalHitCount\":1\\}";
Assert.assertTrue(str.matches("\\{\"hits\":[\\{\"links_count\":[0-9]{1,}\\}"),"Partnership message does not appear");
并得到以下错误 –
Exception in thread "main" java.lang.AssertionError: Partnership message does not appear expected:<true> but was:<false>
我在这里想念的是什么？
解决方法
你不需要逃脱{[在你的输入中.但是你需要在你的正则表达式中逃避[].
试试这个：
String str = "{\"hits\":[{\"links_count\":6,\"totalHitCount\":1}";
System.out.println(str.matches("\\{\"hits\":\\[\\{\"links_count\":[0-9]{1,\"forum_count\":11\\}\\],}\\}"));
