WebService笔记(4)-使用Apache CXF框架发布和调用web服务

  Apache CXF = Celtix + Xfire 支持多种协议： SOAP1.1,1.2 XML/HTTP CORBA（Common Object Request Broker Architecture公共对象请求代理体系结构,早期语言使用的WS。C,c++,C#） 并可以与Spring进行快速无缝的整合 灵活的部署：可以运行在Tomcat,Jboss,Jetty(内置),IBMWS,BeaWL上面。可到Apache官网进行下载。

 创建一个名为crm_service的web项目，把项目作为web服务发布到网络中，具体的配置过程如下：

  1、导入cxf的lib目录下的jar包

  2、在项目中提供CustomerService接口及其实现类，注意因为等一下我们需要用到web服务的接口，所有要在接口上提供@WebService注解，表明这是一个web服务

@WebService
public interface CustomerService {
	public List<Customer> findAll();
}

 

@Transactional
public class CustomerServiceImpl implements CustomerService {
	private JdbcTemplate jdbcTemplate;
	public void setJdbcTemplate(JdbcTemplate jdbcTemplate) {
		this.jdbcTemplate = jdbcTemplate;
	}
	
	public List<Customer> findAll() {
		String sql = "select * from t_customer";
		List<Customer> list = jdbcTemplate.query(sql, new RowMapper<Customer>(){
			public Customer mapRow(ResultSet rs, int arg1) throws SQLException {
				int id = rs.getInt("id");//根据字段名称从结果集中获取对应的值
				String name = rs.getString("name");
				String station = rs.getString("station");
				String telephone = rs.getString("telephone");
				String address = rs.getString("address");
				String decidedzone_id = rs.getString("decidedzone_id");
				return new Customer(id, name, station, telephone, address, decidedzone_id);
			}
		});
		return list;
	}

3、在src目录下创建一个名为cxf.xml的配置文件，用来配置spring框架的内容和web服务的内容

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
xmlns:jaxws="http://cxf.apache.org/jaxws"
xmlns:soap="http://cxf.apache.org/bindings/soap"
	xmlns:context="http://www.springframework.org/schema/context"
	xmlns:aop="http://www.springframework.org/schema/aop"
	xmlns:tx="http://www.springframework.org/schema/tx"
xsi:schemaLocation="http://www.springframework.org/schema/beans 
					http://www.springframework.org/schema/beans/spring-beans.xsd
					http://cxf.apache.org/bindings/soap 
					http://cxf.apache.org/schemas/configuration/soap.xsd
					http://cxf.apache.org/jaxws 
					http://cxf.apache.org/schemas/jaxws.xsd
					http://www.springframework.org/schema/context
						http://www.springframework.org/schema/context/spring-context.xsd

						http://www.springframework.org/schema/tx 
						http://www.springframework.org/schema/tx/spring-tx.xsd
					">
	<!-- 引入CXF Bean定义如下,早期的版本中使用 -->
	<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" />
	
	<!-- 配置数据源 -->
	<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
		<property name="driverClassName" value="com.mysql.jdbc.Driver"/>
		<property name="url" value="jdbc:mysql:///crm_service"/>
		<property name="username" value="root"/>
		<property name="password" value="123"/>
	</bean>
	
	<!-- 事务管理器 -->
	<bean id="txManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
		<property name="dataSource" ref="dataSource"/>
	</bean>
	
	<!-- 支持事务注解 -->
	<tx:annotation-driven transaction-manager="txManager"/>
	
	<bean id="jdbcTemplate" class="org.springframework.jdbc.core.JdbcTemplate">
		<property name="dataSource" ref="dataSource"/>
	</bean>
	
	<bean id="customerService" class="com.iteason.crm.service.CustomerServiceImpl">
		<property name="jdbcTemplate" ref="jdbcTemplate"/>
	</bean>
	
	<!-- 注册服务 -->
	<jaxws:server id="myService" address="/customer">
		<jaxws:serviceBean>
			<ref bean="customerService"/>
		</jaxws:serviceBean>
	</jaxws:server>
</beans>

4、在web.xml中配置spring框架随项目的启动而加载配置文件cxf.xml，并指定web服务的映射路径

  
  <context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath:cxf.xml</param-value>
  </context-param>
  <listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>
  
  
  <servlet>
    <servlet-name>cxf</servlet-name>
    <servlet-class>org.apache.cxf.transport.servlet.CXFServlet</servlet-class>
  </servlet>
  <servlet-mapping>
    <servlet-name>cxf</servlet-name>
    <url-pattern>/service/*</url-pattern>
  </servlet-mapping>
  

5、将该web服务用tomcat启动，并且在浏览器中输入http://localhost:8080/crm_service/service/customer?wsdl，看是否显示说明书，有则成功发布web服务

 

6、命令行中使用wsimport -s . http://localhost:8080/crm_service/service/customer?wsdl，删去所有的类和class，只留下一个服务的接口，即CustomerService接口

 

7、在bos项目中，导入cxf的jar包(maven项目直接配置依赖)

 

8、在bos项目的applicationContext.xml中配置注册crm客户端代理对象

<!-- 注册crm客户端代理对象 -->
	<jaxws:client id="crmClient" 
		serviceClass="com.iteason.crm.service.CustomerService" 
		address="http://192.168.1.180:8080/crm_service/service/customer"/>

9、这样就把CustomerService这个接口给配置好了，在web层可以正常使用了
