java - Parsing the String params received in POST query -

i running simple rest web service receive string params in post query, process them , send string response. in order parse params string

param1=testdata1&param2=testdata2&  

i'm using string.split() under:

@post @produces(mediatype.text_plain) public string post(string str) {   string[] parts = str.split("&");   string part1 = parts[0]; // param1=testdata1   string part2 = parts[1]; // param2=testdata2   ......do on these values , return string....   return str; } 

for getting param values i'll have split again..... can please suggest cleaner , elegant solution these param values..

assuming form parameters, 1 way work either jersey 1.x or jersey 2.x inject multivaluedmap

@post @consumes(mediatype.application_form_urlencoded) public string post(multivaluedmap<string, string> form) {     stringbuilder builder = new stringbuilder();     (map.entry<string, list<string>> params : form.entryset()) {         (string key: params.getvalue()) {             builder.append("key: ").append(params.getkey()).append("; ")                 .append("value: ").append(params.getvalue().get(0)).append("\n");         }     }     return builder.tostring(); } 

if know ahead of time name of form key, create bean.

public class bean {     @formparam("key1")     private string value1;     @formparam("key2")     private string value2;      // getter , setters } 

for jersey 2.x, inject @beanparam

@post @consumes(mediatype.application_form_urlencoded) public response post(@beanparam bean bean) {  } 

for jersey 1.x inject @injectparam

@post @consumes(mediatype.application_form_urlencoded) public response post(@injectparam bean bean) {  } 

note bean injection work other @xxxparams also, not @formparam, instance @queryparam, @pathparam. can mix , match them.

or if know names ahead of time, if don't need bean, can declare form params in method signature

@post @consumes(mediatype.application_form_urlencoded) public response post(@formparam("key1") string value1,                      @formparam("key2") string value2) {  }
