WebService CXF学习（高级篇2）：CXF+Spring+Hibernate

前一节仅仅只讲了与spring整合，没有涉及到数据库，而且是直接将Java象传递到服务端。这一节我起到一个回顾前面章节的作用。用在客户端运用JABX将JAVA对象编组成XML文件，在客户端将XML解组成JAVA并存入数据库。下面我们就着手开发这个Demo: 服务端开发 第一步，编写数据资源层相关接口 DAO编写：

public interface HibernateDao { public void save(UserInfo object); public void delete(UserInfo object); public void update(UserInfo object); public UserInfo get(int id); }

DAO实现类：

public class HibernateDaoImpl extends HibernateDaoSupport implements HibernateDao { public void delete(UserInfo object) { this.getHibernateTemplate().delete(object); } public void save(UserInfo object) { this.getHibernateTemplate().save(object); } public void update(UserInfo object) { this.getHibernateTemplate().update(object); } public UserInfo get(int id) { return (UserInfo) this.getHibernateTemplate().get(UserInfo.class, id); } }

实体对象：

@Entity @Table(name = "userinfo") public class UserInfo implements java.io.Serializable { private static final long serialVersionUID = 2281022190032353574L; @Id @GeneratedValue(strategy = GenerationType.IDENTITY) private Integer id; private String name; private Integer age; private Integer address; public UserInfo() { } public UserInfo(String name, Integer age) { this.name = name; this.age = age; } public UserInfo(String name, Integer age, Integer address) { this.name = name; this.age = age; this.address = address; } public Integer getId() { return this.id; } public void setId(Integer id) { this.id = id; } public String getName() { return this.name; } public void setName(String name) { this.name = name; } public Integer getAge() { return this.age; } public void setAge(Integer age) { this.age = age; } public Integer getAddress() { return this.address; } public void setAddress(Integer address) { this.address = address; } }

第二步：业务逻辑层接口编写业务逻辑接口：

@WebService public interface IService { //public void save(@WebParam(name="info")String xml); public void save(@WebParam(name="dto")UserInfoDTO dto,@WebParam(name="flag")boolean flag); public void update(@WebParam(name="info")String xml); public void delete(@WebParam(name="id")int id); public @WebResult(name="String")String get(@WebParam(name="id")int id); }

接口实现类：

@WebService public class ServiceImpl implements IService { private Logger log = LoggerFactory.getLogger(ServiceImpl.class); private HibernateDao dao; // public void setDao(HibernateDao dao) { // this.dao = dao; // } public void delete(int id) { log.info("delete id is {} user"+id); //UserInfo userInfo = (UserInfo)object; //log.info("this username is:"+userInfo.getName()); //log.info("delete {} information..."+userInfo.getName()); //dao.delete(userInfo); } // public void save(String xml) { // //UserInfo userInfo = (UserInfo)object; // log.info("add {} user..."+xml); // //dao.save(userInfo); // System.out.println("ssss"); // } public void save(UserInfoDTO dto,boolean flag) { System.out.println("name:"+dto.getName()); } public void update(String xml){ ApplicationContext context = new ClassPathXmlApplicationContext( "applicationContext-resources.xml"); this.dao = (HibernateDao)context.getBean("dao"); try { JAXBContext jaxbContext = JAXBContext.newInstance("com.itdcl.model"); Unmarshaller unmarshaller = jaxbContext.createUnmarshaller(); StringReader reader = new StringReader(xml); Customers cus = (Customers)unmarshaller.unmarshal(reader); Customer cust = cus.getCustomer(); UserInfo userInfo = new UserInfo(); System.out.println("Address:"+cust.getAddress()); userInfo.setAddress(cust.getAddress()); System.out.println("Age:"+cust.getAge()); userInfo.setAge(Integer.valueOf(cust.getAge())); System.out.println("Name:"+cust.getName()); //userInfo.setId(2); userInfo.setName(cust.getName()); dao.save(userInfo); } catch (JAXBException e) { e.printStackTrace(); } } public String get(int id){ //return dao.get(id); return null; } }

DAO与Service接口配置：

WebService接口发布：

<?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" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd http://cxf.apache.org/jaxws http://cxf.apache.org/schemas/jaxws.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" /> <bean id="serverUserInfo" class="com.itdcl.model.UserInfoDTO" /> <jaxws:endpoint id="helloWorld" implementor="com.itdcl.service.HelloWorldImpl" address="/HelloWorld" /> <jaxws:endpoint id="myTest" implementor="com.itdcl.service.MyTestImpl" address="/MyTest" /> <jaxws:endpoint id="service" implementor="com.itdcl.service.ServiceImpl" address="/Service">  </jaxws:endpoint> <bean id="jaxWsServiceFactoryBean" class="org.apache.cxf.jaxws.support.JaxWsServiceFactoryBean"> <property name="wrapped" value="true" /> <property name="dataBinding" ref="aegisBean" /> </bean> <bean id="aegisBean" class="org.apache.cxf.aegis.databinding.AegisDatabinding" /> </beans>

第三步：服务端程序编写了，打包部署 客户端开发 第一步：WebService客户端生成，可以手工编写。这里我就通过配置Ant文件来生成WebService客户端:

<?xml version="1.0"?> <project name="cxf" basedir="." default="usage"> <property name="webroot.dir" value="E:/workspace3/CXFSpring" />  <property name="target.class" value="com.itdcl.service.IService" /> <property name="wsdl.name" value="Service.wsdl" /> <property name="src.dir" value="src" /> <property name="client.dir" value="client" /> <property name="server.dir" value="server" /> <property name="compile.dir" value="${webroot.dir}/bin" /> <target name="usage"> <echo message="java2wsdl -->java文件生成wsdl文件，java2wsdl -Ddir=com/starit/cxf/java2wsdl -Dsrc=com.starit.cxf.java2wsdl.Hello" /> <echo message="wsdl2javaClient -->java文件生成client，java2wsdl -Ddir=com/starit/cxf/java2wsdl -Dwsdl=hello.wsdl" /> </target> <target name="java2wsdl"> <echo message="生成wsdl文件" /> <exec dir="${compile.dir}" executable="cmd.exe"> <arg line="/c java2ws" /> <arg line="-o ${wsdl.name} -wsdl ${target.class}" /> </exec>  <move todir="${src.dir}" preservelastmodified="true"> <fileset dir="${compile.dir}"> <include name="**/*.wsdl" /> </fileset> </move> </target> <target name="wsdl2javaClient"> <echo message="生成java client文件" /> <mkdir dir="${client.dir}" /> <exec dir="." executable="cmd.exe"> <arg line="/c wsdl2java" />  <arg line="-d ${client.dir}"/>  <arg line="-client src/*.wsdl" /> </exec> </target> </project>

第二步：WebService接口注册配置

<?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" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd http://cxf.apache.org/jaxws http://cxf.apache.org/schemas/jaxws.xsd">   <jaxws:client id="service" address="http://localhost:9999/cxf/Service" serviceClass="com.itdcl.service.IService" /> </beans>

剩下的事就测试我们整合是否成功了，编写一个JUnit测试类或写一个Main函数测试一下。

public class JaxbSampleClient { private final static String MODEL = "com.itdcl.model"; public static void main(String[] args) throws FileNotFoundException, JAXBException, ParserConfigurationException, TransformerException { ApplicationContext context = new ClassPathXmlApplicationContext( "beans.xml"); IService service = (IService) context.getBean("service"); ObjectFactory factory = new ObjectFactory(); Customer customer = factory.createCustomer(); customer.setId(1); customer.setAge("26"); customer.setName("Josen"); customer.setAddress(100); Customers customers = factory.createCustomers(); customers.setCustomer(customer); DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance(); dbf.setNamespaceAware(true); DocumentBuilder db = dbf.newDocumentBuilder(); Document doc = db.newDocument(); // 转换 JAXBContext jaxbContext = JAXBContext.newInstance(MODEL); Marshaller marshaller = jaxbContext.createMarshaller(); //将customers数据与doc绑定 marshaller.marshal(customers, doc); DOMSource domSource = new DOMSource(doc); StringWriter writer = new StringWriter(); StreamResult result = new StreamResult(writer); TransformerFactory tf = TransformerFactory.newInstance(); Transformer transformer = tf.newTransformer(); transformer.transform(domSource, result); String xmlString = writer.toString(); //System.out.println(xmlString); service.update(xmlString); } }

运行一下，看插入数据库没有。这节到此就靠一段落啦，下节讲解WS-Security
