webService框架cxf的简单使用

一、服务端提供服务

1、pom文件中导入cxf所需的jar包

<dependency>
    			<groupId>org.apache.cxf</groupId>
    			<artifactId>cxf-rt-frontend-jaxws</artifactId>
    			<version>3.0.1</version>
    		</dependency>
    		<dependency>
    			<groupId>org.apache.cxf</groupId>
    			<artifactId>cxf-rt-transports-http</artifactId>
    			<version>3.0.1</version>

2、导入cxf.xml资源文件，需要在资源文件根目录下

<?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/aop
    						http://www.springframework.org/schema/aop/spring-aop.xsd
    						http://www.springframework.org/schema/tx 
    						http://www.springframework.org/schema/tx/spring-tx.xsd">	
    	
    	<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" />
    </beans>

3、在web.xml中配置cxf提供的servlet和资源文件位置

<servlet>
      	<servlet-name>cxf-servlet</servlet-name>
      	<servlet-class>org.apache.cxf.transport.servlet.CXFServlet</servlet-class>
      </servlet>
      
      <servlet-mapping>
      	<servlet-name>cxf-servlet</servlet-name>
      	<url-pattern>/service/*</url-pattern>
      </servlet-mapping>

<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>

4、创建接口并添加实现类，接口上需要有@WebService的注解。

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

public class CustomerServiceImpl implements ICustomerService {
    
    	private JdbcTemplate jdbcTemplate;
    	
    	public void setJdbcTemplate(JdbcTemplate jdbcTemplate) {
    		this.jdbcTemplate = jdbcTemplate;
    	}
    	/**
    	 * 查询所有客户
    	 */
    	public List<Customer> findAll() {
    		String sql = "select * from t_customer";
    		List<Customer> listCustomer = jdbcTemplate.query(sql, new RowMapper<Customer>(){
    			public Customer mapRow(ResultSet rs, int arg1) throws SQLException {
    				int id = rs.getInt("id");
    				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");
    				Customer customer = new Customer(id, name, station, telephone, address, decidedzone_id);
    				return customer;
    			}
    		});
    		return listCustomer;
    	}
    
    }

5、在cxf.xml中注册cxf服务

<bean id="customer" class="com.itheima.bos_crm.service.CustomerServiceImpl">
    		<property name="jdbcTemplate" ref="jdbcTemplate"></property>
    	</bean>
    	<jaxws:server id="myService" address="/customer">
    		<jaxws:serviceBean><ref bean="customer"></ref></jaxws:serviceBean>
    	</jaxws:server>

客户端访问的地址为：ip:端口号/项目名称/web.xml中servlet配置的service/cxf.xml中注册的customer

二、客户端使用服务

1、创建项目并且导入cxf的jar包

2、使用jdk提供的wsimport命令生成本地代码（wsimport为jdk的命令，之前jdk配置过环境变量，就可以直接使用）

D:\myTest>wsimport -s . http://localhost:8088/bos_crm/service/customer?wsdl
    正在解析 WSDL...
    
    
    
    正在生成代码...
    
    
    正在编译代码...
    
    
    D:\myTest>

3、将解析完的接口和实体类的java文件复制到项目中

4、提供spring配置文件，注册客户端代理对象

<jaxws:client id="myClient" serviceClass="com.iss.crm.ICustomerService" address="http://localhost:8088/bos_crm/service/customer"/>

5、直接调用接口中的方法即可自动创建出代理对象，远程调用customer中的方法。
