CXF发布RestFul WebService和SOAP WebService

CXF发布RestFul WebService和SOAP WebService

Apache CXF可以发布多种协议的WebService，Spring支持整合cxf到项目中，可以简化后台构架，以下是一个cxf发布SOAP协议WebService和RestFul WebService的简单例子。

一、添加依赖

	<dependency>
	    <groupId>org.apache.cxf</groupId>
	    <artifactId>cxf-rt-frontend-jaxws</artifactId>
	    <version>3.1.11</version>
	</dependency>
	<dependency>
	    <groupId>org.apache.cxf</groupId>
	    <artifactId>cxf-rt-frontend-jaxrs</artifactId>
	    <version>3.1.11</version>
	</dependency>	
	<dependency>
	    <groupId>javax.ws.rs</groupId>
	    <artifactId>javax.ws.rs-api</artifactId>
	    <version>2.1-m07</version>
	</dependency>
	<dependency>
	    <groupId>org.codehaus.jackson</groupId>
	    <artifactId>jackson-jaxrs</artifactId>
	    <version>1.9.13</version>
	</dependency>
	<dependency>
	    <groupId>com.fasterxml.jackson.jaxrs</groupId>
	    <artifactId>jackson-jaxrs-json-provider</artifactId>
	    <version>2.9.0.pr3</version>
	</dependency>	

二、web.xml中添加CXFServlet拦截处理请求

  <servlet>
  	<servlet-name>CXFServlet</servlet-name>
  	<servlet-class>org.apache.cxf.transport.servlet.CXFServlet</servlet-class>
  	<load-on-startup>1</load-on-startup>
  </servlet>
  
  <servlet-mapping>
  	<servlet-name>CXFServlet</servlet-name>
  	<url-pattern>/services/*</url-pattern>
  </servlet-mapping>

三、开发RestFul风格的WebService

1) RestFul服务接口定义

@Consumes("application/json")
@Produces("application/json")
public interface IStudentService {

	/**
	 * 
	 * @param student
	 * @param page
	 * @return
	 */
	@GET
	@Path(value = "/findStudentList/{pageSize}/{curPage}")
	public List<StudentVO> findStudent(@QueryParam("") StudentVO student, @PathParam("") PageVO page);

	/**
	 * 
	 * @param students
	 */
	@POST
	@Path(value = "/addStudent")
	@Consumes("application/json")
	@Produces("application/json")
	public void addStudent(List<StudentVO> students);
}

2) RestFul服务接口实现

@Path("/service")
@Component
public class StudentService implements IStudentService {

	@Override
	public List<StudentVO> findStudent(StudentVO student, PageVO page) {
		List<StudentVO> list = new ArrayList<StudentVO>();
		StudentVO s1 = new StudentVO();
		s1.setId(1L);
		s1.setName("name1");
		s1.setNo("090440112");
		s1.setGrade(1);
		list.add(s1);
		return list;
	}

	@Override
	public void addStudent(List<StudentVO> students) {

	}

}

3) 发布RestFul服务

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
        xmlns:context="http://www.springframework.org/schema/context" xmlns:p="http://www.springframework.org/schema/p"
        xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:tx="http://www.springframework.org/schema/tx"
        xmlns:aop="http://www.springframework.org/schema/aop" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xmlns:jaxws="http://cxf.apache.org/jaxws"  xmlns:jaxrs="http://cxf.apache.org/jaxrs" 
        xsi:schemaLocation="http://www.springframework.org/schema/beans  
      http://www.springframework.org/schema/beans/spring-beans-4.0.xsd  
      http://www.springframework.org/schema/context  
      http://www.springframework.org/schema/context/spring-context-4.0.xsd  
      http://www.springframework.org/schema/mvc  
      http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd
      http://www.springframework.org/schema/tx  
      http://www.springframework.org/schema/tx/spring-tx-4.0.xsd
      http://www.springframework.org/schema/aop  
      http://www.springframework.org/schema/aop/spring-aop-4.0.xsd
      http://cxf.apache.org/jaxrs  
	  http://cxf.apache.org/schemas/jaxrs.xsd
	  http://cxf.apache.org/jaxws  
	  http://cxf.apache.org/schemas/jaxws.xsd
      ">
      
      <bean id="jsonProvider" class="org.codehaus.jackson.jaxrs.JacksonJsonProvider"/>
      
      <jaxrs:server id="studentRestService" address="/student">
      	<jaxrs:serviceBeans>
      		<ref bean="studentService"></ref>
      	</jaxrs:serviceBeans>
      	<jaxrs:providers>
      		<ref bean="jsonProvider"/>
      	</jaxrs:providers>
      </jaxrs:server>
</beans>

4) 调用RestFul服务

 

四、开发SOAP协议的WebService

1) SOAP服务接口定义

@WebService
public interface ICourseService {

	@Path("/findCourseList")
	public String findCourseList(String req);
}

2) SOAP服务接口实现

@Component
public class CourseService implements ICourseService {

	@Override
	public String findCourseList(String req) {

		return "course list";
	}

}

3) 发布SOPA服务

Spring配置发布如下，也可以使用jaxws:endpoint的方式配置发布服务

      <jaxws:server id="courseWsService" serviceClass="com.ttt.server.logistics.security.service.ICourseService" address="/course">
      	<jaxws:serviceBean>
      		<ref bean="courseService"/>
      	</jaxws:serviceBean>
      	<jaxws:inInterceptors>
      		<bean class="org.apache.cxf.interceptor.LoggingInInterceptor" /> 
      	</jaxws:inInterceptors>
      	<jaxws:outInterceptors>
      		<bean class="org.apache.cxf.interceptor.LoggingOutInterceptor" />  
      	</jaxws:outInterceptors>
      </jaxws:server>

4) 调用SOAP服务

Spring中配置Client，通过注入Client到其他Bean中，调用SOAP服务

      <jaxws:client id="courseWebService" serviceClass="com.ttt.server.logistics.security.service.ICourseService" address="http://127.0.0.1:8080/ttt.server/services/course">
      	<jaxws:inInterceptors>
      		<bean class="org.apache.cxf.interceptor.LoggingInInterceptor" /> 
      	</jaxws:inInterceptors>
      	<jaxws:outInterceptors>
      		<bean class="org.apache.cxf.interceptor.LoggingOutInterceptor" />  
      	</jaxws:outInterceptors>
      </jaxws:client>

使用JaxWsProxyFactoryBean调用SOAP服务

		JaxWsProxyFactoryBean factory = new JaxWsProxyFactoryBean();
		factory.setServiceClass(ICourseService.class);
		factory.setAddress("http://127.0.0.1:8080/ttt.server/services/course");
		ICourseService server = (ICourseService) factory.create();
		System.out.println(server.findCourseList("111"));

完。
