caused By:com.sun.xml.internal.bind.v2.runtime.illegalannotationsexception:1 counts of IllegalAnnotationExceptionsjava.util.List is an interface, and JAXB cannot handle the interface.      This problem is related to the following location: at        java.util.List        private  Java.util.Map Com.rg2.webservice.jaxws_asm. Getrolesresponse._return at        Com.rg2.webservice.jaxws_asm. Getrolesresponse

It is necessary to annotate the CXF when processing the map type, otherwise the above error will be reported.

@WebService  Public Interface HelloWorld {    public  string Say (string str);          Public List<role> getrolebyuser (user user);         /**      * Get the     role of all users @return     *    /@XmlJavaTypeAdapter ( Mapadapter. class )    public map<string, list<role>> getroles ();} 

Where Mapadapter is written separately

Start the server method

Open the browser without error

Automatically generate code from clients using WSDL2, as previously written

The server-side interface is then invoked through the client class

 PackageCom.rg2.webservice;Importjava.util.List; Public classClient { Public Static voidMain (string[] args) {HelloWorldService service=NewHelloWorldService (); HelloWorld Helloworldport=Service.gethelloworldport (); Myrolearray GetRoles=Helloworldport.getroles (); List<MyRole> rolelist =Getroles.item;  for(inti = 0; I < rolelist.size (); i++) {Myrole my=Rolelist.get (i); System.out.print (My.key+ ":");  for(Role role:my.value) {System.out.print (Role.getid ()+","+role.getrolename ()); } System.out.println ("==============="); }    }}

The result of the operation is:
