2022-12-30 20:05:01

1、在web-info目录下新建目录wsdl

2、在1步的目录下

新建文件user.wsdl

<?xml version="1.0" encoding="UTF-8" standalone="no"?>

user.xsd的文件内容如下：

<?xml version="1.0" encoding="UTF-8"?>

<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema"

        targetNamespace="http://service.zttc.edu.cn"

        xmlns:tns="http://service.zttc.edu.cn"

        elementFormDefault="qualified">

    <xsd:element name="upload" type="tns:upload"></xsd:element>

    <xsd:element name="uploadResponse" type="tns:uploadResponse"></xsd:element>

    <xsd:complexType name="uploadResponse">

        <xsd:sequence/>

    </xsd:complexType>

<!-- 文件上传的byte类型 -->

    <xsd:complexType name="upload">

        <xsd:sequence>

            <xsd:element name="file" type="xsd:base64Binary"></xsd:element>

        </xsd:sequence>

    </xsd:complexType>

    <xsd:complexType name="licenceInfo">

            <xsd:element name="nickname" type="xsd:string"/>

        </xsd:sequence>

    </xsd:complexType>

</xsd:schema>

3、修改web.xml

<?xml version="1.0" encoding="UTF-8"?>

<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5">

    <listener>

        <listener-class>com.sun.xml.ws.transport.http.servlet.WSServletContextListener</listener-class>

    </listener>

    <servlet>

        <servlet-name>UserService</servlet-name>

        <servlet-class>com.sun.xml.ws.transport.http.servlet.WSServlet</servlet-class>

    </servlet>    

    <servlet-mapping>

        <servlet-name>UserService</servlet-name>

        <url-pattern>/us</url-pattern>

    </servlet-mapping>

</web-app>

4、在web-info下新建文件sun-jaxws.xml

<?xml version="1.0" encoding="UTF-8"?>

<endpoints xmlns="http://java.sun.com/xml/ns/jax-ws/ri/runtime" version="2.0">

  <endpoint name="UserService"

       implementation="cn.edu.zttc.service.UserServiceImpl" url-pattern="/us"/>

</endpoints>

5、使用wsimport命令生成服务端的服务接口类

6、编写服务端接口类

package cn.edu.zttc.service;

import java.io.FileNotFoundException;

import java.io.FileOutputStream;

import java.io.IOException;

import java.util.List;

import javax.annotation.Resource;

import javax.jws.WebService;

import javax.xml.namespace.QName;

import javax.xml.stream.XMLStreamException;

import javax.xml.stream.XMLStreamReader;

import javax.xml.stream.events.XMLEvent;

import javax.xml.ws.WebServiceContext;

import javax.xml.ws.soap.MTOM;

import org.zttc.dao.UserDao;

import org.zttc.dao.UserException;

import org.zttc.vo.User;

import com.sun.xml.ws.api.message.Header;

import com.sun.xml.ws.api.message.HeaderList;

import com.sun.xml.ws.developer.JAXWSProperties;

@WebService(endpointInterface="cn.edu.zttc.service.IUserService",

            wsdlLocation="WEB-INF/wsdl/user.wsdl",

            serviceName="UserService",

            portName="UserServicePort",

            targetNamespace="http://service.zttc.edu.cn")

@MTOM

public class UserServiceImpl implements IUserService {

    private UserDao userDao = UserDao.newInstance();

    //注入webservice的上下文对象

    @Resource

    private WebServiceContext ctx;

    @Override

    public void add(User user) throws UserException {

        checkRegister();

        userDao.add(user);

    }

    private void checkRegister() throws UserException {

        try {

            HeaderList headers = (HeaderList)ctx.getMessageContext().get(JAXWSProperties.INBOUND_HEADER_LIST_PROPERTY);

            QName qname = new QName("http://service.zttc.edu.cn","licenceInfo");

            if(headers==null) throw new UserException("该功能需要进行权限控制");

            Header header = headers.get(qname,true);

            if(header==null) throw new UserException("该功能需要进行权限控制");

            XMLStreamReader xsr = header.readHeader();

            User u = x2user(xsr);

            User tu = userDao.loadByUsername(u.getUsername());

            if(tu==null) throw new UserException("你所使用的用户不是系统的授权用户");

            if(!tu.getPassword().equals(u.getPassword()))

                throw new UserException("授权用户的密码信息不正确!");

        } catch (XMLStreamException e) {

            e.printStackTrace();

        }

    }

    private User x2user(XMLStreamReader xsr) throws XMLStreamException {

        User u = new User();

        while(xsr.hasNext()) {

            int event = xsr.next();

            if(event==XMLEvent.START_ELEMENT) {

                String name = xsr.getName().toString();

                if(name.equals("username")) {

                    u.setUsername(xsr.getElementText());

                } else if(name.equals("password")) {

                    u.setPassword(xsr.getElementText());

                } else if(name.equals("nickname")) {

                    u.setNickname(xsr.getElementText());

                }

            }

        }

        return u;

    }

    @Override

    public void delete(String username) throws UserException {

        checkRegister();

        userDao.delete(username);

    }

    @Override

    public List<User> list() {

        return userDao.list();

    }

    @Override

    public User login(String username, String password) throws UserException {

        return userDao.login(username, password);

    }

    @Override

    public void upload(byte[] file) {

        FileOutputStream fos = null;

        System.out.println(file);

        try {

            fos = new FileOutputStream("d:/webservice/1.jpg");

            fos.write(file);

            fos.flush();

        } catch (FileNotFoundException e) {

            e.printStackTrace();

        } catch (IOException e) {

            e.printStackTrace();

        } finally {

            try {

                fos.close();

            } catch (IOException e) {

                e.printStackTrace();

            }

        }

    }

}

需要导入的jax-ws的jar包如下：

这里服务端获取header的信息的方法又多了一个，具体看上面的实现类的代码中的方法checkRegister

客户端设置heade的方式还有如下方法：

import javax.xml.bind.JAXBContext;
import javax.xml.bind.JAXBElement;
import javax.xml.bind.Marshaller;
import javax.xml.namespace.QName;
import javax.xml.parsers.DocumentBuilderFactory;
import javax.xml.ws.soap.MTOMFeature;
import com.sun.xml.ws.api.message.Headers;
import com.sun.xml.ws.developer.WSBindingProvider;

@Test

    public void testAdd() {

        try {

            //1、将一个对象转换为xml通过JAXB

            JAXBContext ctx = JAXBContext.newInstance(LicenceInfo.class);

            User ru = new User();

            ru.setNickname("超级管理");

            ru.setUsername("admin");

            ru.setPassword("1232323");

            LicenceInfo info = new LicenceInfo();

            info.setRegisterUser(ru);

            QName name = new QName(ns,"licenceInfo");

            JAXBElement<LicenceInfo> jele = new JAXBElement<LicenceInfo>(name,LicenceInfo.class,info);

            Marshaller mars = ctx.createMarshaller();

            mars.setProperty(Marshaller.JAXB_FRAGMENT,true);

            mars.setProperty(Marshaller.JAXB_ENCODING, "UTF-8");

            //2、转换为DOM

            Document doc = DocumentBuilderFactory.newInstance().newDocumentBuilder().newDocument();

            mars.marshal(jele, doc);

            //3、通过Headers.create方法完成header的添加

            //获取WSBindingProvider

            WSBindingProvider wsb = (WSBindingProvider)port;

            wsb.setOutboundHeaders(Headers.create(doc.getDocumentElement()));

            User u = new User();

            u.setNickname("张三");

            u.setPassword("123");

            u.setUsername("zs");

            port.add(u);

        }catch(Exception e) {

            System.out.println(e.getMessage());

        } 

    }

    @Test

    public void testUpload() {

        try {

            byte[] file = FileUtils.readFileToByteArray(new File("d:/kh/img/美女01.jpg"));

            port.upload(file);

        } catch (IOException e) {

            e.printStackTrace();

        }

    }
