导读：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,}}"),"Partnershi

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}],}}"));
