how to create query parser to parse query param in spring REST -

my query parameter this:

q=name:abc+age:20+roleid:(23|45)|audeince:(23|24).here + , | or 

i have accept query param spring controller , have make query solar fetch data.



@controller @requestmapping("/user") public class bookscontroller {  @requestmapping(value="/details", method=requestmethod.get) public responseentity<?> getuser(final httpservletrequest request) {    string params = requestparams.get("q")[0];     //passing string make query in apache solar } } 

i need write parser split param value make solar query.how write query parser split above url make solar query satisfying or , condition.name:abc+age:20+roleid:(23|45)|audeince:(23|24) means create solar query name=abc , age=20 , roleid in (23,24) or audience in (23,24) .this way user sends query.

eg:firstname:(abc|bcd)+lastname:abc+emailid:abc+dsid:abc|countrycd:us+audienceid:(123+678)

first using regex convert firstname:(abc|bcd)+ -----------segment1

lastname:abc+.............segment2

emailid:abc+.............segment3

dsid:abc|--------------segment4

countrycd:us+----------segment5

audienceid:(123+678)------segment 6;

like many segments may come in url

i have class called

class queryobj{

private string field;

private list value;

private string internaloperator;

private string externaloperator;

}

firstname:(abc|bcd)+ again using regex map this

field=firstname

value={abc,bcd}

internaloperator=|

externaloperator=+

like second segment emailid:abc+

field=emailid

value=abc

internaloperator=null

externaloperator=+

same other segments .if there n segments have n objects.

after add each object linked list.if internaloperator or externaloperator null leave null .how can achieve that

you can use regex pattern "key:value operator" segment

pattern keyvaluepattern = pattern.compile("[\\w]+:([\\w@.]+|\\([\\w|+@.]+\\))[+|]?");
