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/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"));
