cxf 结合 spring 发布web service时不能实例化User对象的问题5

在service层中调用了Dao方法来进行数据库的操作然后又重新了UserWebservice接口及其实现类在实现类中直接调用service的方法
domain中
User类

public abstract class User {
private String userName;
private String userPassword;
private String mobile;
private String email;
private String nickname;
private String region;
private java.util.Date birthday ;
private String telephone;
private String address;
private String postcode;
private String signature;
private String imageUrl;
private int userID;
private Set<Right> rightSet = new HashSet<Right>();
//getter 和setter略

@Override
public String toString() {
return "User [userName=" + userName + ", userPassword=" + userPassword
+ ", mobile=" + mobile + ", email=" + email + ", nickname="
+ nickname + ", region=" + region + ", birthday=" + birthday
+ ", telephone=" + telephone + ", address=" + address
+ ", postcode=" + postcode + ", signature=" + signature
+ ", imageUrl=" + imageUrl + ", userID=" + userID
+ ", rightSet=" + rightSet.size() + "]";
}
}

public class Member extends User {

	@Override
	public boolean getIsAdmin() {
		// TODO Auto-generated method stub
		return false;
	}
}

public class Admin extends User {

	@Override
	public boolean getIsAdmin() {
		// TODO Auto-generated method stub
		return true;
	}
}

Right类

public class Right {
	private int rightID;
	private String name;
	private Set<User> userSet = new HashSet<User>();
	
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
	public int getRightID() {
		return rightID;
	}
	public void setRightID(int rightID) {
		this.rightID = rightID;
	}
	


	public Set<User> getUserSet() {
		return userSet;
	}
	public void setUserSet(Set<User> userSet) {
		this.userSet = userSet;
	}
	@Override
	public String toString() {
		return "Right [rightID=" + rightID + ", name=" + name + ", userSet="
				+ userSet.size() + "]";
	}
	
}

发布成web service后写了一个

public class ClientTest {
	
	public static void main(String[] args) throws Exception {
		 JaxWsProxyFactoryBean factory = new JaxWsProxyFactoryBean();
	     factory.setServiceClass(UserWebservice.class);
	     factory.setAddress("http://localhost:8080/TwoTablesSSH/services/UserWebService");
	     
	     UserWebservice webservice = (UserWebservice) factory.create();
	    ]User user = webservice.queryByID(1);
	     System.out.println(user);
	}

}

结果出错了
Exception in thread "main" org.apache.cxf.binding.soap.SoapFault: Marshalling Error: A cycle is detected in the object graph. This will cause infinitely deep XML: User [userName=admin, userPassword=admin, mobile=admin, email=admin, nickname=admin, region=null, birthday=2011-11-25 17:16:37.0, telephone=null, address=null, postcode=null, signature=null, imageUrl=null, userID=1, rightSet=4] -> Right [rightID=1, name=UpdateRight, userSet=1] -> User [userName=admin, userPassword=admin, mobile=admin, email=admin, nickname=admin, region=null, birthday=2011-11-25 17:16:37.0, telephone=null, address=null, postcode=null, signature=null, imageUrl=null, userID=1, rightSet=4]

at $Proxy30.queryByID(Unknown Source)

出现了循环引用对象的问题，看网上的解决办法，将@XmlTransient放在了Right类中的
@XmlTransient
public Set<User> getUserSet() {
return userSet;
}

结果出现了无法实例化User的问题

采纳的答案

jaxb提供了有这种扩展。（CycleRecoverable接口）解决循环引用问题，你试试：

public abstract class User implements CycleRecoverable{

//...
 public Object onCycleDetected(Context arg0) {
　　Company temp = new Company ();
　　temp.setId(id);
　　return temp;
　　}

}


public class Right {  

}
