Apache CXF 提供方便的Spring整合方法,可以通过注解、Spring标签式配置来暴露Web Services和消费Web Services
各种类型的Annotation。@WebService和@WebMethod是WSDL映射Annatotion。这些Annotation将描述Web Service的WSDL文档元素和Java源代码联系在一起。
@SOAPBinding是一个绑定的annotation用来说明网络协议和格式。
1、@WebService annotation的元素name,serviceName和targetNamespace成员用来描述
wsdl:portType,wsdl:service,和targetNameSpace生成WebService中的WSDL文件。
2、@SOAPBinding是一个用来描述SOAP格式和RPC的协议的绑定Annotation。
3、@WebMethod Annotation的operationName成员描述了wsdl:operation,而且它的操作描
述了WSDL文档中的SOAPAction头部。这是客户端必须要放入到SQAPHeader中的数
值,SOAP 1.1中的一种约束。
4、@WebParam Annotation的partName成员描述了WSDL文档中的wsdl:part。
5、@WebResult Annotation的partName成员描述了wsdl:part用来返回WSDL文档的值。
例如下面使用annotation定义了一个webservice:
import java.util.List;
import javax.jws.WebMethod;
import javax.jws.WebParam;
import javax.jws.WebResult;
import javax.jws.WebService;
import com.cxf.pojo.User;
@WebService(targetNamespace = "http://jdk.study.hermit.org/client")
public interface UserService {
@WebMethod(operationName="Insert")
public void insert( @WebParam(name = "userId") String userid,
@WebParam(name = "userName") String username,
@WebParam(name = "userEmail") String useremail,
@WebParam(name = "userAge") int userage);
@WebMethod(operationName="GetUserById")
@WebResult(name = "result")
public User getUserById(@WebParam(name="userid") String userid);
@WebMethod(operationName="GetAllUsers")
@WebResult(name = "result")
public List getAllUsers();
}
其实现类如下所示:
import java.util.List;
import javax.jws.WebService;
import com.cxf.dao.UserDao;
import com.cxf.pojo.User;
import com.cxf.service.UserService;
@WebService(endpointInterface="com.cxf.service.UserService")
public class UserServiceImpl implements UserService {
private UserDao userDao;
public List getAllUsers() {
return userDao.findAllUser();
}
public User getUserById(String userid) {
return userDao.findUserById(userid);
}
public void insert(String userid, String username, String useremail, int userage) {
User user=new User();
user.setUserage(userage);
user.setUseremail(useremail);
user.setUserid(userid);
user.setUsername(username);
userDao.insert(user);
System.out.println("insert successfully!");
}
public void setUserDao(UserDao userDao) {
this.userDao = userDao;
}
}
注意:实现类中的@WebService,其中的endpointInterface成员指定了该类实现的接口
在Spring的配置文件中,需要对其进行配置:
首先在ApplicationContext.xml(Spring的配置文件)中引入CXF的XML Scheam 配置文件),如下:
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:jaxws="http://cxf.apache.org/jaxws"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd
http://cxf.apache.org/jaxws http://cxf.apache.org/schemas/jaxws.xsd">
<!―还需要引入以下3个关于CXF的资源文件,这三个文件在cxf.jar中-->
<import resource="classpath:META-INF/cxf/cxf.xml" />
<import resource="classpath:META-INF/cxf/cxf-extension-soap.xml"/>
<import resource="classpath:META-INF/cxf/cxf-servlet.xml" />
…… …… …… …… …… …… …… …… …… ……
</bean>
其次就是在Spring的配置文件中配置webservice,如下所示:
<jaxws:endpoint id="userManager" address="/UserManager"
implementorClass="com.cxf.service.UserService">
<jaxws:implementor>
<bean id="userServiceImpl"
class="com.cxf.service.impl.UserServiceImpl">
<property name="userDao">
<ref bean="userDao" />
</property>
</bean>
</jaxws:implementor>
</jaxws:endpoint>
注意:
①、address 为webservice发布的地址
②、implementorClass 为该webservice实现的接口
③、<jaxws:implementor></jaxws:implementor>之间定义的是implementorClass 指定接口的实现类
另外,在Spring的配置文件中配置完成后,需要修改web.xml文件
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath*:beans.xml</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<servlet>
<servlet-name>CXFServlet</servlet-name>
<servlet-class>
org.apache.cxf.transport.servlet.CXFServlet
</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>CXFServlet</servlet-name>
<url-pattern>/services/*</url-pattern>
</servlet-mapping>
注意<url-pattern>/ services /*</url-pattern>配置,CXFServlet会拦截此类url,进行处理。上面配置的webservice将通过如下URL访问到:
http://localhost:8080/cxf-ws/services/ UserManager
UserManager为<jaxws:endpoint >标签中address属性对应的值
cxf-ws为本项目的名称
配置完成之后,将项目部署到tomcat上
输入URL:http://localhost:8080/cxf-ws/services/ UserManager?wsdl
将会看到生成的wsdl文件
为了能够直接访问到com.cxf.service.UserService中的insert方法,进行如下测试:
创建一个insertUser.html页面:
<html>
<head>
<script type="text/javascript">
function post() {
var xmlhttp=false;
if (!xmlhttp && typeof XMLHttpRequest!='undefined') {
try {
xmlhttp = new XMLHttpRequest();
} catch (e) {
xmlhttp=false;
}
}
if (!xmlhttp && window.createRequest) {
try {
xmlhttp = window.createRequest();
} catch (e) {
xmlhttp=false;
}
}
var dest = document.getElementByIdx_x('destination').value;
xmlhttp.open("POST", dest, true);
xmlhttp.onreadystatechange=function() {
if (xmlhttp.readyState==4) {
document.getElementByIdx_x("result").innerHTML = xmlhttp.responseText;
}
}
xmlhttp.setRequestHeader("Man", "POST " + dest + " HTTP/1.1")
xmlhttp.setRequestHeader("MessageType", "CALL")
xmlhttp.setRequestHeader("Content-Type", "text/xml");
var texta = document.getElementByIdx_x('texta');
var soapmess = texta.value;
xmlhttp.send(soapmess);
}
</script>
</head>
<body>
hi there
<form id="forma">
<textarea id="texta" rows="10" cols="80">
<?xml version='1.0' encoding='UTF-8'?>
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:xsi="http://www.w3.org/1999/XMLSchema-instance" xmlns:xsd="http://www.w3.org/1999/XMLSchema">
<SOAP-ENV:Body>
<Insert>
<userId>2005221104210066</userId>
<userName>Leon Cao</userName>
<userEmail>[email protected]</userEmail>
<userAge>23</userAge>
</Insert>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>
</textarea>
<p>
<input type="text" id="destination" size="50" value="http://localhost:8080/cxf-ws/services/UserManager"></input>
<p>
<input type="button" name="submit" value="Submit"></input>
</form>
<div id="container"></div>
Result:
<hr>
<div id="result">
</div>
<hr>
<div id="soap">
</div>
</body>
</html>
在该测试页面需要注意标记为红色的部分,如下是一个soap message:
<?xml version='1.0' encoding='UTF-8'?>
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:xsi="http://www.w3.org/1999/XMLSchema-instance" xmlns:xsd="http://www.w3.org/1999/XMLSchema">
<SOAP-ENV:Body>
<Insert>
<userId>2005221104210066</userId>
<userName>Leon Cao</userName>
<userEmail>[email protected]</userEmail>
<userAge>23</userAge>
</Insert>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>
注意:
①<SOAP-ENV:Body>标签之间<Insert>对应@WebMethod(operationName="Insert")
中的operationName属性的值
②<userId>、<userName>、<userEmail>、<userAge>标签对各自对应着insert方法中
@WebParam中name属性的值:
@WebParam(name = "userId") String userid,
@WebParam(name = "userName") String username,
@WebParam(name = "userEmail") String useremail,
@WebParam(name = "userAge") int userage);
当向webservice上发送该soap消息的时候将自动解析该soap消息,将Insert解析为insert方法,将<userId>、<userName>、<userEmail>、<userAge>标签对之间
的值解析为相对应的参数userid、username、useremail、userage
③<input type="text" id="destination" size="50" value="http://localhost:8080/cxf-ws/services/UserManager"></input>
该文本标签中的value属性为webservice的地址
运行该页面,点击Submit后将在数据库中插入一行数据,即调用了inser方法成功
