WSContext
代码,这个建议用axis命令
生成,因为内部涉及wsdl的拼接,比较麻烦,而且实际开发中,有可能你并不了解对方的代码结构

wsdl标签大意
♦ types
元素
使用XML模式语言,声明在WSDL文档中的其他位置使用的复杂数据类型与元素,可理解为就是**定义webservice方法请求与响应参数的
**
♦ import
元素
类似于XML模式文档中的import元素,用于从其他WSDL文档中导入WSDL定义;
♦ message
元素
使用在WSDL文档的type元素中定义或在import元素引用的外部WSDL文档中定义的XML模式的内置类型、复杂类型或元素描述了消息的有效负载;
♦ portType
元素 和 operation
元素
描述了Web服务的接口并定义了他的方法。portType元素和operation元素类似于java接口和接口中定义的方法声明。operation元素使用一个或者多个message类型来定义他的输入和输出的有效负载;
♦ Binding
元素
将portType元素和operation元素赋给一个特殊的协议和编码样式;
♦ service
元素
负责将Internet地址赋给一个具体的绑定;
具体解释
wsdl:definitions标签
xmlns:xxxx
做此wsdl的定义,里面有很多
xmlns:xxxx
,其中后半部分的xxxx
会在其他标签中被引用
比如,在上面wsdl文件中的 wsdl:message的Response标签 中,返回类型定义为:type=“tns1
:WSContext”,则对应Axis客户端代码就要这样写:
//因为tns1在 <wsdl:definitions>标签 中定义值为 urn:client,所以要向下面这样拼
call.setReturnType(new javax.xml.namespace.QName("urn:client", "WSContext"));//一般如果不是java中自带的类型,比如string、int等,大概率都是自定义类型,
//此处的WSContext肯定是自定义类型,所以必须在这里赋值class类型,因为Axis不知道WSContext是什么类型
call.setReturnClass(WSContext.class);
假如是 type=“xsd:string
”,则对应Axis客户端代码就是:
//xsd属于xml自带标签,进入org.apache.axis.Constants.XSD_STRING的源码可以看见其值就是xsd:string
call.setReturnType(org.apache.axis.Constants.XSD_STRING);
targetNamespace
webserivce的名称空间,一般与方法名拼接一起使用,axis代码使用如下:
call.setOperationName(new QName("名称空间", "方法名"));
注意:
targetNamespace
不是必须与方法名拼接在一起进行axis客户端调用,要看wsdl:message
标签的方法中是否有前缀
比如下面:方法Response 与 Request 中都有前缀ns0
,而ns0
的值恰好与targetNamespace
一致,所以上面的:
new QName("名称空间", "方法名")
就没问题了
但是本wsdl示例文档的 wsdl:message
标签方法无前缀,比如下图的logout
方法:
则axis代码就可以直接写一个方法名:
call.setOperationName(new QName( "logout"));
wsdl:message标签
详解
方法标签,对应发布webservice的接口方法,其中
xxxResponse
代表接口方法的返回
xxxRequest
或者直接xxx方法名
代表接口方法的接收
比如本文的wsdl示例文档中的:
正对应其5个方法:
而
wsdl:message
标签的内容,正对应请求参数
与返回值参数
- 请求参数对应上图
request
中的5个 - 返回参数对应上图的
tns1:WSContext
,也就是下面wsdl:types
标签中的类型定义,是5个小类型的合体
axis调用
1.这里对应本文wsdl示例的
axis
代码调用如下,因为对应方法名的loginRequest、loginResponse没有前缀修饰:
call.setOperationName(new QName( "login"));
2.但如果是下面这种,就必须有前缀对应的QName拼接:
call.setOperationName(new QName("tns在<wsdl:definitions>内定义的值","方法名emeService"));
wsdl:definitions
中的tns
展示,大部分tns
与名称空间targetNamespace
相同
wsdl:types标签
详解1
声明在其他标签中要使用的
元素
和类型
,比如接口方法参数类型、返回值类型
比如本文档示例的wsdl中,wsdl:types
标签内容如下,其实就是定义了接口方法的参数类型:
<wsdl:types><schemaxmlns="http://www.w3.org/2001/XMLSchema" targetNamespace="urn:client"><import namespace="http://schemas.xmlsoap.org/soap/encoding/"/><complexType name="WSContext"><sequence><element name="dbType" type="xsd:int"/><element name="dcName" nillable="true" type="xsd:string"/><element name="password" nillable="true" type="xsd:string"/><element name="sessionId" nillable="true" type="xsd:string"/><element name="slnName" nillable="true" type="xsd:string"/><element name="userName" nillable="true" type="xsd:string"/></sequence></complexType></schema>
</wsdl:types>
其中,complexType
为一个复合类型,它包含的具体小类型在sequence
标签的element
中,当我们调用
<wsdl:message name="loginRequest">
的方法时,返回的结果格式如下,其实就是返回了WSContext
类,这个类包含了其他5个字符串和整数的属性
axis调用1
结合最上面
wsdl
示例的message
:
请求:
<wsdl:message name="loginRequest"><wsdl:part name="userName" type="xsd:string"> </wsdl:part><wsdl:part name="password" type="xsd:string"> </wsdl:part><wsdl:part name="slnName" type="xsd:string"> </wsdl:part><wsdl:part name="dcName" type="xsd:string"> </wsdl:part><wsdl:part name="language" type="xsd:string"> </wsdl:part><wsdl:part name="dbType" type="xsd:int"> </wsdl:part>
</wsdl:message>
响应:
<wsdl:message name="loginByLtpaTokenResponse"><wsdl:part name="loginByLtpaTokenReturn" type="tns1:WSContext"> </wsdl:part>
</wsdl:message>
此
wsdl:types
标签对应的调用代码如下注意:请求参数需要写参数名,设置返回值时不用写返回值名
请求:
call.addParameter("userName", XMLType.XSD_STRING, ParameterMode.IN);
call.addParameter("password", XMLType.XSD_STRING, ParameterMode.IN);
call.addParameter("slnName", XMLType.XSD_STRING, ParameterMode.IN);
call.addParameter("dcName", XMLType.XSD_STRING, ParameterMode.IN);
call.addParameter("language", XMLType.XSD_STRING, ParameterMode.IN);
call.addParameter("dbType", XMLType.XSD_INT, ParameterMode.IN);
响应:
//设置wsdl中返回值类型及其修饰标签
call.setReturnType(new QName("urn:client", "WSContext"));
//因为返回值类型为WSContext,不是基本类型,所以必须设置其calss类,否则报错
call.setReturnClass(WSContext.class);
这个响应的返回值类型,推荐由
Axis
的命令直接生成,内部构成比较复杂
详解2
在举一个不同格式的例子
下面这种格式的wsdl:types
标签,与上面大同小异,意思就是:
在wsdl:types
中,定义了**emeService
方法 ** 的
- 请求参数类型是
String
,名称是arg0
- 返回值类型是
String
,名称是return
结果证明:
axis调用2
上面的返回值名字为
return
,类型为xs:string
注意:axis设置请求参数时需要写参数名,而设置返回值时不用写返回值名
xs:string
在axis
中可以用代码XMLType.XSD_STRING
标识,java基本类型都可以用XMLType
表示
call.setReturnType(XMLType.XSD_STRING);
wsdl:portType标签
表达了发布
webservice
接口的代码结构
以本文wsdl文档示例为例:
wsdl:portType
的name
的值:一般对应发布webservice
的接口名。wsdl:operation
的name
的值:对应webservice
接口的方法名,parameterOrder
为方法参数名。wsdl:input
与wsdl:output
:对应了输入输出,即接口方法请求与返回的message
定义,可以根据其name
名字去wsdl:message
标签找对应的方法定义。
wsdl:binding与wsdl:service标签
好像不涉及Axis代码调用需要编写的部分,暂时没有仔细分析
- Binding - 特定端口类型的具体协议和数据格式规范的绑定。
- Port - 定义为协议/数据格式绑定与具体Web访问地址组合的单个服务访问点。
- Service- 相关服务访问点的集合。
