我无法让 Jersey RESTful 服务正常工作。
我收到以下错误
The server encountered an internal error () that prevented it from fulfilling this request.

服务是:
@Path("/agents")
public class AgentService {
@POST
@Consumes({MediaType.APPLICATION_JSON + ";charset=utf-8"})
@Produces(MediaType.APPLICATION_JSON + ";charset=utf-8")
public String createAgent(AgentTO input) {
try{
// Agent agent = input.createAgent()
// PersistenceService.getInstance().save(agent);
return input.getName();
} catch (Exception se) {
se.printStackTrace();
}
return null;
}
这是我想要收到的对象:
@XmlRootElement
public class AgentTO {
private String name;
private String phone;
public AgentTO(){}
public AgentTO(String phone, String name){
this.phone = phone;
this.name = name;
}
我正在做这样的POST:
curl -H "Content-Type: application/json" -v -X POST -d '{"phone":"123","name":"asd2"}' http://127.0.0.1:8080/project/agents
我之前制作的资源就像这个一样,但这似乎不想工作:P
你能帮我解决这个问题吗?
问候,马丁
