SSM之Web Services

本文主要是介绍SSM之Web Services，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

1.介绍

WebService基本介绍
WebService中的WSDL详细解析

1.1 wsdl介绍

    <wsdl:service name="HelloServiceDemo"><wsdl:port name="HelloServiceDemoHttpSoap11Endpoint" binding="ns:HelloServiceDemoSoap11Binding"><soap:address location="http://localhost:8080/ssm_crud/services/HelloServiceDemo.HelloServiceDemoHttpSoap11Endpoint/"/></wsdl:port></wsdl:service>

从下面可以看到soap:operation soapAction=“urn:sayHello”，urn:sayHello就是我们要访问的方法名

    <wsdl:binding name="HelloServiceDemoSoap11Binding" type="ns:HelloServiceDemoPortType"><soap:binding transport="http://schemas.xmlsoap.org/soap/http" style="document"/><wsdl:operation name="sayHello"><soap:operation soapAction="urn:sayHello" style="document"/><wsdl:input><soap:body use="literal"/></wsdl:input><wsdl:output><soap:body use="literal"/></wsdl:output></wsdl:operation></wsdl:binding>

    <wsdl:portType name="HelloServiceDemoPortType"><wsdl:operation name="sayHello"><wsdl:input message="ns:sayHelloRequest" wsaw:Action="urn:sayHello"/><wsdl:output message="ns:sayHelloResponse" wsaw:Action="urn:sayHelloResponse"/></wsdl:operation></wsdl:portType>

    <wsdl:message name="sayHelloRequest"><wsdl:part name="parameters" element="ns:sayHello"/></wsdl:message><wsdl:message name="sayHelloResponse"><wsdl:part name="parameters" element="ns:sayHelloResponse"/></wsdl:message>

    <wsdl:types><xs:schema attributeFormDefault="qualified" elementFormDefault="qualified" targetNamespace="http://serviceimpl.webservice.zy.com"><xs:element name="sayHello"><xs:complexType><xs:sequence><xs:element minOccurs="0" name="name" nillable="true" type="xs:string"/></xs:sequence></xs:complexType></xs:element><xs:element name="sayHelloResponse"><xs:complexType><xs:sequence><xs:element minOccurs="0" name="return" nillable="true" type="xs:string"/></xs:sequence></xs:complexType></xs:element></xs:schema></wsdl:types>

1.2 项目结构

2.axis2集成

2.1 添加依赖

	<axis2.version>1.7.8</axis2.version><!--axis2 begin--><dependency><groupId>org.apache.axis2</groupId><artifactId>axis2-spring</artifactId><version>${axis2.version}</version></dependency><dependency><groupId>org.apache.axis2</groupId><artifactId>axis2-transport-http</artifactId><version>${axis2.version}</version></dependency><dependency><groupId>org.apache.axis2</groupId><artifactId>axis2-transport-local</artifactId><version>${axis2.version}</version></dependency><dependency><groupId>org.apache.axis2</groupId><artifactId>axis2-xmlbeans</artifactId><version>${axis2.version}</version></dependency><!--axis2 end-->

2.2 创建相关类

public interface IHelloService {public String sayHello(String name);
}

@Service("helloService")
public class HelloServiceImpl implements IHelloService{@Overridepublic String sayHello(String name) {return "你好，"+name+" 欢迎来到websercie!!!";}
}

2.3 applicationContext.xml

    <!--axi2交给spring管理--><bean id="applicationContext"class="org.apache.axis2.extensions.spring.receivers.ApplicationContextHolder" />

2.4 web.xml

  <!-- 开启webservice:Axis2 --><servlet><display-name>Apache-Axis Servlet</display-name><servlet-name>AxisServlet</servlet-name><servlet-class>org.apache.axis2.transport.http.AxisServlet</servlet-class><load-on-startup>2</load-on-startup></servlet><servlet-mapping><servlet-name>AxisServlet</servlet-name><url-pattern>*.jws</url-pattern></servlet-mapping><servlet-mapping><servlet-name>AxisServlet</servlet-name><url-pattern>/services/*</url-pattern></servlet-mapping><!-- Axis2 -->

2.5 添加services.xml

注意：services.xml的目录结构必须按照这下面路径设置，不然会读取不到这个配置文件的
/webapp/WEB-INF/services/webservices/META-INF/services.xml ，其中，只有webservices可以任意命名，其他的文件夹名称不能改变

<?xml version="1.0" encoding="UTF-8"?>
<serviceGroup><!--接口名称--><service name="HelloServiceDemo" scope="application"><!--接口描述--><description>axis2 实现的webservice样例</description><!--这个是比较老的接口，若spring版本较高，用第二个，不然启动不能实例化--><!--<parameter name="ServiceObjectSupplier">--><!--org.apache.axis2.extensions.spring.receivers.SpringAppContextAwareObjectSupplier--><!--</parameter>--><parameter name="ServiceObjectSupplier" locked="false">org.apache.axis2.extensions.spring.receivers.SpringServletContextObjectSupplier</parameter><!--接口实现类--><parameter name="SpringBeanName">helloService</parameter><messageReceivers><messageReceiver mep="http://www.w3.org/ns/wsdl/in-only" class="org.apache.axis2.rpc.receivers.RPCInOnlyMessageReceiver"/><messageReceiver mep="http://www.w3.org/ns/wsdl/in-out" class="org.apache.axis2.rpc.receivers.RPCMessageReceiver"/></messageReceivers></service>
</serviceGroup>

2.5 运行

输入：IP+端口+项目名+services+接口名？wsdl
http://localhost:8080/ssm_crud/services/HelloServiceDemo?wsdl

用soapui访问，如图：
