Creating a web service with complex types
提问by yellavon
I'm new to web services and I created a basic project in eclipse with one exposed method. I was able to deploy my webservice and it works fine. The code is below.
我是 Web 服务的新手，我使用一种公开的方法在 Eclipse 中创建了一个基本项目。我能够部署我的网络服务并且运行良好。代码如下。
import javax.jws.WebMethod;
import javax.jws.WebParam;
import javax.jws.WebService;
@WebService(targetNamespace="http://test.com", name="testService")
public class WebService {
@WebMethod(operationName="start")
public String start(@WebParam(name="inputParameter") String inputParameter) {
return startMethod(inputParameter);
}
}
My question is how do I set up this method to deal with complex types. I want to receive a number of parameters, but I don't want to just receive them as a bunch of strings. I was thinking of having some sort of wrapper object that contained all the parameters I need for my method. Any advice on how to do this? Do I need additional annotations to create the WSDL? Thanks!
我的问题是如何设置此方法来处理复杂类型。我想接收许多参数，但我不想只将它们作为一堆字符串接收。我正在考虑拥有某种包装对象，其中包含我的方法所需的所有参数。关于如何做到这一点的任何建议？我是否需要额外的注释来创建 WSDL？谢谢！

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
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，任何用户定义的类正确注释如下所述，都可以用作任何 WebMethod 的参数或返回类型
@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;
}
}

First, setup what complex types your webservice call or response contains in your WSDL
首先，设置您的 Web 服务调用或响应包含在 WSDL 中的复杂类型
<xsd:element name="AWebServiceElementName">
<xsd:complexType>
<xsd:sequence>
<xsd:element maxOccurs="1" minOccurs="1" name="header" type="tns:ReplyHeader"/>
<xsd:element maxOccurs="1" minOccurs="1" name="body">
<xsd:complexType>
<xsd:sequence>
<xsd:element maxOccurs="unbounded" minOccurs="0" name="acomplextype" type="tns:acomplextype"/>
<xsd:element maxOccurs="1" minOccurs="1" name="anothercomplextype" type="tns:anothercomplextype"/>
</xsd:sequence>
</xsd:complexType>
</xsd:element>
</xsd:sequence>
</xsd:complexType>
</xsd:element>
and then define what your complex types contains:
然后定义您的复杂类型包含的内容：
<xsd:complexType name="acomplextype">
<xsd:sequence>
<xsd:element maxOccurs="1" minOccurs="1" name="somefieldid" type="xsd:long"/>
<xsd:element maxOccurs="1" minOccurs="1" name="somestring" type="xsd:string"/>
</xsd:sequence>
</xsd:complexType>
<xsd:complexType name="anothercomplextype">
<xsd:sequence>
<xsd:element maxOccurs="1" minOccurs="1" name="somefieldid" type="xsd:long"/>
<xsd:element maxOccurs="1" minOccurs="1" name="somestring" type="xsd:string"/>
</xsd:sequence>
</xsd:complexType>
On the Java-side you need a wrapper class that contain these fields with getters and setters
在 Java 端，您需要一个包装类，其中包含这些带有 getter 和 setter 的字段
