Question

如何创建soap webservice所需的参数？

@WebService
public class MyService {
    //how can I make city param required?
    @WebMethod
    public ComplexResponse lookup(@WebParam(name = "city") String city) {

    }
}

Answer 1

添加

@XmlElement(required=true, nillable=false)

到参数应该工作：

public ComplexResponse lookup(@WebParam(name = "city") @XmlElement(required=true, nillable=false) String city)
