java - 查找并替换以新字符串开头和结尾的子字符串 java

Question

我想查找并替换以字符串“sps.jsp”开头并以子字符串“FILE_ARRAY_INDEX=12”结尾的子字符串。

以下是我的字符串内容

beginning with strings............[sps.jsp]..anything between.. [FILE_ARRAY_INDEX=12] ending with some strings....

下面是我的代码

 Pattern r = Pattern.compile("sps.jsp[\\s\\S]*?FILE_ARRAY_INDEX=12");
 Matcher m = r.matcher(InputStr);
 if (m.find( )) 
 {
   System.out.println("Found value: " + m.group() );
 }

我无法获取我的模式并用新字符串替换它。

您只需 String::replaceAll使用此正则表达式 sps.jsp(.*?)FILE_ARRAY_INDEX=12

String inputStr = "....";//your input
inputStr = inputStr.replaceAll("sps.jsp(.*?)FILE_ARRAY_INDEX=12", "[some string]");

输出

beginning with strings............[some string] ending with some strings....
