webservice系统学习笔记10-使用jax-ws创建基于tomcat类型的容器的ws服务

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"

    <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 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();
        }
    }
