WebService CXF学习（入门篇5）：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：

@WebServicepublic 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：

@WebServicepublic 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：

<?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:aop="http://www.springframework.org/schema/aop"xmlns:tx="http://www.springframework.org/schema/tx"xmlns:jaxws="http://cxf.apache.org/jaxws"xsi:schemaLocation="http://cxf.apache.org/jaxws http://cxf.apache.org/schemas/jaxws.xsd    http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd    http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.0.xsd    http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.0.xsd"><!--*******************Hibernate数据库持久层配置文件***********************--><bean id="propertyConfigurer"class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"><property name="locations"><list><value>classpath:jdbc.properties</value></list></property></bean><bean id="dataSource"class="org.springframework.jdbc.datasource.DriverManagerDataSource"><property name="driverClassName" value="${driverClassName}" /><property name="url" value="${jdbc.url}" /><property name="username" value="${jdbc.username}" /><property name="password" value="${jdbc.password}" /></bean><bean id="sessionFactory"class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean"><property name="dataSource"><ref local="dataSource" /></property><property name="hibernateProperties"><props><prop key="hibernate.dialect">${hibernate.dialect}</prop><prop key="hibernate.show_sql">${show_sql}</prop><prop key="hibernate.format_sql">${format_sql}</prop><!-- 缓存设置 --><prop key="cache.use_query_cache">${cache.use_query_cache}</prop><prop key="cache.use_second_level_cache">${cache.use_second_level_cache}</prop><prop key="cache.provider_class">${cache.provider_class}</prop><!-- C3P0连接池配置 --><prop key="c3p0.acquire_increment">${c3p0.acquire_increment}</prop><prop key="c3p0.max_statements">${c3p0.max_statements}</prop><prop key="c3p0.min_size">${c3p0.min_size}</prop><prop key="c3p0.max_size">${c3p0.max_size}</prop><prop key="c3p0.timeout">${c3p0.timeout}</prop><prop key="c3p0.idle_test_period">${c3p0.idle_test_period}</prop></props></property><property name="namingStrategy"><bean class="org.hibernate.cfg.ImprovedNamingStrategy" /></property><property name="packagesToScan" value="com.itdcl.pojo" /></bean><bean id="dao" class="com.itdcl.dao.HibernateDaoImpl"><property name="sessionFactory" ref="sessionFactory" /></bean></beans>

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.xsdhttp://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:serviceFactory><ref bean="jaxWsServiceFactoryBean" /></jaxws:serviceFactory>--></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" /><!-- webservice接口 --><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="${webroot.dir}/bin" /><target name="usage"><echomessage="java2wsdl         -->java文件生成wsdl文件，java2wsdl -Ddir=com/starit/cxf/java2wsdl -Dsrc=com.starit.cxf.java2wsdl.Hello" /><echomessage="wsdl2javaClient       -->java文件生成client，java2wsdl -Ddir=com/starit/cxf/java2wsdl -Dwsdl=hello.wsdl" /></target><target name="java2wsdl"><echo message="生成wsdl文件" /><exec dir="${compile.dir}" executable="cmd.exe"><arg line="/c java2ws" /><arg line="-o ${wsdl.name} -wsdl ${target.class}" /></exec><!-- copy资源文件 --><move todir="${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" /><!-- 生成的java所存目录 --><arg line="-d ${client.dir}"/><!-- wsdl文件所在路径 --><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.xsdhttp://cxf.apache.org/jaxws http://cxf.apache.org/schemas/jaxws.xsd"><!--  jaxws:client id="helloWorldClient"address="http://localhost:9999/cxf/HelloWorld"serviceClass="com.itdcl.service.IHelloWorld" />--><!--  jaxws:client id="myTestClient"address="http://localhost:9999/cxf/MyTest"serviceClass="com.itdcl.service.IMyTest" />--><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
