WebService系列博客{5}[Soap协议的简单解析]

Types: 描述了所有请求参数的类型

举例说明：每一个wsdl文件都有会如下格式的文件

<types>
<xsd:schema>
<xsd:import namespace="http://ws.java.com/" schemaLocation="http://192.168.1.103:7878/web?xsd=1"/>
</xsd:schema>
</types>

访问: http://192.168.1.103:7878/web?xsd=1(案例地址)将会看到更加详细的方法解析。例如传递参数的类型。返回参数的类型()

<xs:schema xmlns:tns="http://ws.java.com/" xmlns:xs="http://www.w3.org/2001/XMLSchema" version="1.0" targetNamespace="http://ws.java.com/">
<xs:element name="add" type="tns:add"/>
<xs:element name="addResponse" type="tns:addResponse"/>
<xs:element name="minute" type="tns:minute"/>
<xs:element name="minuteResponse" type="tns:minuteResponse"/>
<xs:complexType name="add">
<xs:sequence>
<xs:element name="arg0" type="xs:int"/>
<xs:element name="arg1" type="xs:int"/>
</xs:sequence>
</xs:complexType>
<xs:complexType name="addResponse">
<xs:sequence>
<xs:element name="return" type="xs:int"/>
</xs:sequence>
</xs:complexType>
<xs:complexType name="minute">
<xs:sequence>
<xs:element name="arg0" type="xs:int"/>
<xs:element name="arg1" type="xs:int"/>
</xs:sequence>
</xs:complexType>
<xs:complexType name="minuteResponse">
<xs:sequence>
<xs:element name="return" type="xs:int"/>
</xs:sequence>
</xs:complexType>
</xs:schema>

每一个complexType 在用wsimport命令生成Java的时候都会有相应命名的java文件

Message：SOAP消息和types对应的方法阐述元素相对应  message|types

<message name="add">
<part name="parameters" element="tns:add"/>
</message>
<message name="addResponse">
<part name="parameters" element="tns:addResponse"/>
</message>
<message name="minute">
<part name="parameters" element="tns:minute"/>
</message>
<message name="minuteResponse">
<part name="parameters" element="tns:minuteResponse"/>
</message>

portType：指明服务器的接口，并且通过operation指定in和out的消息。其中input表示参数。Output表示返回值

<portType name="WsServerDao">
<operation name="add">
<input wsam:Action="http://ws.java.com/WsServerDao/addRequest" message="tns:add"/>
<output wsam:Action="http://ws.java.com/WsServerDao/addResponse" message="tns:addResponse"/>
</operation>
<operation name="minute">
<input wsam:Action="http://ws.java.com/WsServerDao/minuteRequest" message="tns:minute"/>
<output wsam:Action="http://ws.java.com/WsServerDao/minuteResponse" message="tns:minuteResponse"/>
</operation>
</portType>

Binding ： 指定我们传递消息所使用的格式。一般都是literal

<soap:binding transport="http://schemas.xmlsoap.org/soap/http" style="document"/>
<operation name="add">
<soap:operation soapAction=""/>
<input>
<soap:body use="literal"/>
</input>
<output>
<soap:body use="literal"/>
</output>
</operation>
<operation name="minute">
<soap:operation soapAction=""/>
<input>
<soap:body use="literal"/>
</input>
<output>
<soap:body use="literal"/>
</output>
</operation>
</binding>

<service name="WsServerImplService">
<port name="WsServerImplPort" binding="tns:WsServerImplPortBinding">
<soap:address location="http://192.168.1.103:7878/web"/>
</port>
</service>
