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：

</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">
        <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 ${target.class}" />
        </exec>
        <!-- copy资源文件 -->
        <move todir="${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.xsd
        http://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);
    }

}
