我有一个 JAX-RS Jersey WebService，我试图接受 XML 数据（或 JSON）并返回String显示传递的记录总数的响应。
这是我的服务代码：
@Path("customers")
@Singleton
public class CustomersResource {
...
@POST
@Path("addall")
@Produces("text/html")
@Consumes(javax.ws.rs.core.MediaType.APPLICATION_XML)
public String addCustomers(List<Customer> customerList) {
return "success : received " + customerList.size() ;
}
...
}
这是我的客户代码：
public static void main(String[] args) {
Client client = Client.create();
WebResource webresource = client.resource( "http://localhost:8080/restdemo/services/customers/addall");
String input = "<customerList><customer><name>name1</name></customer><customer><name>name2</name></customer></customerList>";
String response = webresource.type("application/xml").post( String.class, input );
System.out.println(response);
}
错误：
