我有以下代码
@XmlRootElement
@XmlAccessorType(XmlAccessType.FIELD)
public class SamplePojo {
private Serializable id;
private String name;
public Serializable getId() {
return id;
}
public void setId(Serializable id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
和一个简单的Web服务接口,
@WebService
public interface SampleManagementService {
@WebMethod
@WebResult(name = "samplePojo")
public SamplePojo update(@WebParam(name = "samplePojo") SamplePojo pojo) throws SampleException;
}
我正在使用CXF-2.3.6和org.apache.cxf.tools.java2ws.JavaToWS
从java代码生成WSDL。当我运行命令时
java2ws -verbose -o sample.wsdl -wsdl -frontend jaxws com.test.cxf.webservice.sample.SampleManagementService
我遇到了以下异常
cxfJavaToWSDL:

我试图创建SerializableAdapter
但没有运气。任何人都可以告诉我处理Serializable
参数传递的正确方法是什么?
答案 0 :(得分:2)
那不会奏效。 Serializable
无法由JAXB处理,JAXB是处理Java和XML之间实际转换时CXF使用的绑定引擎。
要修复,您必须决定是否要在XML中使用id
属性。如果你不这样做,只需用@XmlTransient
标记吸气剂就可以了。但是,如果你做想要一个id,那么你必须决定它将如何映射到一个字符串(如果该字段是一个具体的类而不仅仅是任何一个字段,这将更简单任意可序列化的东西)。如果你有/ String
的转换效果很好,你只需将你的属性更改为字符串属性或制作虚假属性:
@XmlRootElement
@XmlAccessorType(XmlAccessType.NONE) // Note the change here too!
public class SamplePojo {
private Serializable id;
private String name;
@XmlTransient
public Serializable getId() {
return id;
}
public void setId(Serializable id) {
this.id = id;
}
@XmlElement(name = "id")
public String getStringId() {
return id.toString(); // Or whatever...
}
public void setStringId(String id) {
this.id = IdFactory.getIdFromString(id); // Or whatever...
}
@XmlElement
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
答案 1 :(得分:1)
您可以在此用例中使用XmlAdapter
。您需要指定一个可映射的值类型(在下面的示例中为String
),然后提供必要的转换逻辑:
<强> SerializableAdapter 强>
package forum10798310;
import java.io.Serializable; import javax.xml.bind.annotation.adapters.XmlAdapter;
public class SerializableAdapter extends XmlAdapter<String, Serializable>{
@Override
public Serializable unmarshal(String v) throws Exception {
// TODO Auto-generated method stub
return null;
}
@Override
public String marshal(Serializable v) throws Exception {
// TODO Auto-generated method stub
return null;
}
}
<强> SamplePojo 强>
@XmlJavaTypeAdapter
注释用于链接XmlAdapter
。
package forum10798310;
import java.io.Serializable;
import javax.xml.bind.annotation.*;
import javax.xml.bind.annotation.adapters.XmlJavaTypeAdapter;
@XmlRootElement
@XmlAccessorType(XmlAccessType.FIELD)
public class SamplePojo {
@XmlJavaTypeAdapter(SerializableAdapter.class)
private Serializable id;
private String name;
public Serializable getId() {
return id;
}
public void setId(Serializable id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
