Java + jackson parsing error Unrecognized character escape
Set your mapper
mapper.configure(JsonParser.Feature.ALLOW_BACKSLASH_ESCAPING_ANY_CHARACTER, true);
mlpdemo\mlpdemoins
is an invalid string you can't use it in JSON . But you can use mlpdemo\\mlpdemoins
easily.
below code works fine for me :
String jsonData = "{ \"provider\" : null , \"password\" : \"a\", \"userid\" : \"mlpdemo\\\\mlpdemoins\" }";
ObjectMapper mapper=new ObjectMapper();
System.out.println(mapper.readTree(jsonData));
It will produce this output JSON :
{"provider":null,"password":"a","userid":"mlpdemo\\mlpdemoins"}
