Java String 删除部分字符串

Question

I have a Java String like this

  "functional_type":"endpoint","configuration":[],"neighbours":{ "1": {"id":1,"name": "ep"}}},

And I wish to replace this part

"neighbours":{ "1": {

with another string. Moreover the number one is could be any number like for example 23 or 1903434 in order to have at the end this:

"functional_type":"endpoint","configuration":[],"filed":{"id":1,"name": "ep"}}},

Answer 1

You should escape "{".

String s = "\"functional_type\":\"endpoint\",\"configuration\":[],\"neighbours\":{ \"1\": {\"id\":1,\"name\": \"ep\"}}},";
System.out.println(s.replaceAll("\"neighbours\":\\{ \"\\d+\": \\{", "\"filed\":{"));

result:

"functional_type":"endpoint","configuration":[],"filed":{"id":1,"name": "ep"}}},
