java - Invoke RESTful webservice with parameter -
i have simple restful web service print "hello world !" i'm using netbeans , code looks like:
package resource; import javax.ws.rs.core.context; import javax.ws.rs.core.uriinfo; import javax.ws.rs.consumes; import javax.ws.rs.put; import javax.ws.rs.path; import javax.ws.rs.get; import javax.ws.rs.produces; @path("simple") public class simpleresource { @context private uriinfo context; /** creates new instance of simpleresource */ public simpleresource() { } @get @produces("application/xml") public string getxml() { //todo return proper representation object return "<greeting>hello world !</greeting>"; } @put @consumes("application/xml") public void putxml(string content) { } } i call web service url : http://localhost:8080/webservice/resources/simple. now, want send parameter web service, print parameter after "hello world" message.
how can that?
thanks!
the 2 main ways of handling parameter in rest via parsing path , via extracting query part.
path parameters
these handle case — /foo/{fooid} — {fooid} template replaced parameter want:
@get @produces("text/plain") @path("/foo/{fooid}") public string getfoo(@pathparam("fooid") string id) { // ... } these great case can consider parameter describing resource.
query parameters
these handle case — /?foo=id — you'd doing traditional form processing:
@get @produces("text/plain") @path("/") public string getfoo(@queryparam("foo") string id) { // ... } these great case consider parameter describing adjunct resource, , not resource itself. @formparam annotation extremely similar, except handling posted form instead of get-style parameters
other types of parameters
there other types of parameter handling supported jax-rs spec (matrix parameters, header parameters, cookie parameters) work in same way programmer, rarer or more specialized in use. reasonable place start exploring details jax-rs javadoc itself, has useful links.
