我强调了一种情况，在这种情况下无法调用以 java.lang.Object 作为参数的 Web 服务方法。
我正在使用 Netbeans 7.1 和 Tomcat 7。
为了创建、部署和访问 Web 服务，我遵循了以下给出的步骤: http://java.sun.com/developer/technicalArticles/J2SE/jax_ws_2/
网络服务端点如下:
package com.metrows;
import javax.jws.WebService;
import javax.jws.WebMethod;
import javax.jws.WebParam;
/**
*
* @author 298790
*/
@WebService(serviceName = "NewWebService")
public class NewWebService {
/**
* This is a sample web service operation
*/
@WebMethod(operationName = "hello")
public String hello(@WebParam(name = "name") String txt) {
return "Hello " + txt + " !";
}
/**
* Web service operation
*/
@WebMethod(operationName = "sendObjParam")
public Object sendObjParam(@WebParam(name = "paramObj") Object paramObj) {
//TODO write your implementation code here:
System.out.println("In NewWebService.sendObjParam(...) "+paramObj);
return paramObj;
}
/**
* Web service operation
*/
@WebMethod(operationName = "passCustomParams")
@Oneway
public void passCustomParams(@WebParam(name = "tenant") Tenant tenant) {
System.out.println("In NewWebService.passCustomParams(...) : tenant = " + tenant);
System.out.println(": " + tenant.getMap());
}
}
租户如下:
package com.valueobjects;
import java.util.HashMap;
/**
*
* @author 298790
*/
public class Tenant {
private String tenantId;
private String tenantName;
private HashMap map;
public String getTenantId() {
return tenantId;
}
public void setTenantId(String tenantId) {
this.tenantId = tenantId;
}
public String getTenantName() {
return tenantName;
}
public void setTenantName(String tenantName) {
this.tenantName = tenantName;
}
public HashMap getMap() {
return map;
}
public void setMap(HashMap map) {
this.map = map;
}
}
客户端如下:
package metro_ws_client;
/**
*
* @author 298790
*/
public class Metro_WS_Client {
/**
* @param args the command line arguments
*/
public static void main(String[] args) {
// TODO code application logic here
System.out.println(hello("Aao Thakur !!!"));
Tenant tenant = new Tenant();
tenant.setTenantId("lnt");
tenant.setMap(new Tenant.Map());
passCustomParams(tenant);
Object o = new Object();
//String s = "Shot";
sendObjParam(o);
}
private static String hello(java.lang.String name) {
metro_ws_client.NewWebService_Service service = new metro_ws_client.NewWebService_Service();
metro_ws_client.NewWebService port = service.getNewWebServicePort();
return port.hello(name);
}
private static Object sendObjParam(java.lang.Object paramObj) {
com.metrows.NewWebService_Service service = new com.metrows.NewWebService_Service();
com.metrows.NewWebService port = service.getNewWebServicePort();
return port.sendObjParam(paramObj);
}
private static void passCustomParams(com.metrows.Tenant tenant) {
com.metrows.NewWebService_Service service = new com.metrows.NewWebService_Service();
com.metrows.NewWebService port = service.getNewWebServicePort();
port.passCustomParams(tenant);
}
}
在服务器启动期间，我得到以下异常(不是完整的堆栈跟踪，因为它是重复的):

现在对网络方法“hello”的调用是成功的，但是当调用“sendObjParam”时出现以下异常；此外，无法在客户端中创建 java.util.Map 并将其设置在租户对象中:

请指导我如何将标准 Java 对象——具体或接口(interface)、具有非原始成员的自定义对象传递给 Web 服务？
最佳答案
您传递给 Web 服务客户端方法的对象需要由 JAXB 序列化。这至少意味着它们需要用 @XMLRootElement 进行注释。这当然意味着您不能传入 new Object()(无论如何这几乎没有用)。
关于java - 将对象传递给 JAX WS，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/9262911/
