JAX-WS基于JAXB，因此您只能将JAXB支持的类型作为Web方法参数传递。因此，任何正确注释的用户定义类（如下所述）都可以用作任何WebMethod的参数或返回类型

JAX-WS is based on JAXB so you can pass only JAXB supported types as a web method parameters. So any user defined class properly annotated such as mentioned below can be used as parameter or return type of any WebMethod

@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "Person")
public class Person {    
    @XmlElement(name = "firstName")
    protected String firstName;    
    @XmlElement(name = "lastName")
    protected String lastName;

    public String getFirstName() {
        return firstName;
    }

    public void setFirstName(String value) {
        this.firstName = value;
    }

    public String getLastName() {
        return lastName;
    }

    public void setLastName(String value) {
        this.lastName = value;
    }
}
