基于Axis2+MyBatis的WebService.doc

新建工程Flower(用MyBatis连接数据库)1.准备工作：将所用到的.jar包(包括mysql-connector-java-5.1.13-bin.jar，mybatis-3.0.4.jar，mybatis-3.0.4-sources.jar)打包成用户自定义库，在Flower中引用。将下载的axis2-1.5.4-war.zip包解压，取出axis2.war包拷贝到apache-tomcat-6.0.26webapps中,登录http:/localhost:8080/axis2，点击Administration，输入帐号admin,密码axis2可进入，点击Upload Service,将打包的.aar文件上传。文件布局如下图所示：2.service端设计(1).编写MyBatis的配置(src/Configuration.xml)： !- (2).编写服务类的父类(src/service/BaseMybatisDao.java)：package service;import java.io.Reader;import org.apache.ibatis.io.Resources;import org.apache.ibatis.session.SqlSessionFactory;import org.apache.ibatis.session.SqlSessionFactoryBuilder;public class BaseMybatisDao protected static SqlSessionFactory sessionFactory; static tryReader reader = Resources.getResourceAsReader(Configuration.xml);sessionFactory = new SqlSessionFactoryBuilder().build(reader);catch(Exception e)e.printStackTrace(); (3).编写服务端代码(src/service/student/StudentService.java)：package service.student;import java.text.SimpleDateFormat;import java.util.Iterator;import java.util.List;import org.apache.axiom.om.OMAbstractFactory;import org.apache.axiom.om.OMElement;import org.apache.axiom.om.OMFactory;import org.apache.axiom.om.OMNamespace;import org.apache.ibatis.session.SqlSession;import service.BaseMybatisDao;import service.student.bean.StudentBean;public class StudentService extends BaseMybatisDaoprivate static SqlSession session;StudentBean student;SimpleDateFormat sdf = new SimpleDateFormat(yyyy-MM-dd);/新增一条记录public void studentAdd(OMElement in)OMElement elem = in.getFirstElement();Iterator it = elem.getChildElements();OMElement ome;String sid = ;String sname = ;String ssex = ;String sbirthday = ;String saddress = ;while(it.hasNext()ome = (OMElement)it.next();if(ome.getLocalName()=sid)sid = ome.getText();else if(ome.getLocalName()=sname)sname = ome.getText();else if(ome.getLocalName()=ssex)ssex = ome.getText();else if(ome.getLocalName()=sbirthday)sbirthday = ome.getText();else if(ome.getLocalName()=saddress)saddress = ome.getText(); student = new StudentBean(); student.setSid(Integer.parseInt(sid); student.setSname(sname); student.setSsex(ssex); try student.setSbirthday(sdf.parse(sbirthday); catch(Exception e) e.printStackTrace(); student.setSaddress(saddress); session = sessionFactory.openSession(); session.insert(student.sinsert, student); mit(); session.close();/修改历史记录public void studentEdit(OMElement in)OMElement elem = in.getFirstElement();Iterator it = elem.getChildElements();OMElement ome;String sid = ;String sname = ;String ssex = ;String sbirthday = ;String saddress = ;while(it.hasNext()ome = (OMElement)it.next();if(ome.getLocalName()=sid)sid = ome.getText();else if(ome.getLocalName()=sname)sname = ome.getText();else if(ome.getLocalName()=ssex)ssex = ome.getText();else if(ome.getLocalName()=sbirthday)sbirthday = ome.getText();else if(ome.getLocalName()=saddress)saddress = ome.getText(); student = new StudentBean(); student.setSid(Integer.parseInt(sid); student.setSname(sname); student.setSsex(ssex); try student.setSbirthday(sdf.parse(sbirthday); catch(Exception e) e.printStackTrace(); student.setSaddress(saddress); session = sessionFactory.openSession(); session.update(student.sedit, student); mit(); session.close();/删除无效的记录public void studentDel(OMElement in)Integer sid = Integer.parseInt(in.getText();session = sessionFactory.openSession();session.delete(student.sdel, sid);mit();session.close();/根据条件查询符合条件的记录public OMElement studentQuery(OMElement in)Integer sid = Integer.parseInt(in.getText();OMFactory fac = OMAbstractFactory.getOMFactory();OMNamespace omNs = fac.createOMNamespace(/, student);OMElement element = fac.createOMElement(studentQuery, omNs);session = sessionFactory.openSession();List list = session.selectList(student.sselect,sid);OMElement item; OMElement id; OMElement name; OMElement sex; OMElement birthday; OMElement address; StudentBean bean; for(int i=0;ilist.size();i+) bean = new StudentBean(); bean = (StudentBean)list.get(i); item = fac.createOMElement(item, omNs);element.addChild(item);id = fac.createOMElement(id, omNs);id.setText(bean.getSid().toString();item.addChild(id);name = fac.createOMElement(name, omNs);name.setText(bean.getSname();item.addChild(name);sex = fac.createOMElement(sex, omNs);sex.setText(bean.getSsex();item.addChild(sex);birthday = fac.createOMElement(birthday, omNs);birthday.setText(bean.getSbirthday().toString();item.addChild(birthday);address = fac.createOMElement(address, omNs);address.setText(bean.getSaddress();item.addChild(address); session.close();return element;/选择全部数据public OMElement studentList(OMElement in)OMFactory fac = OMAbstractFactory.getOMFactory();OMNamespace omNs = fac.createOMNamespace(/, student);OMElement element = fac.createOMElement(studentInfo, omNs);session = sessionFactory.openSession();List list = session.selectList(student.sellist);OMElement item; OMElement id; OMElement name; OMElement sex; OMElement birthday; OMElement address; StudentBean bean; for(int i=0;ilist.size();i+) bean = new StudentBean(); bean = (StudentBean)list.get(i); item = fac.createOMElement(item, omNs);element.addChild(item);id = fac.createOMElement(id, omNs);id.setText(bean.getSid().toString();item.addChild(id);name = fac.createOMElement(name, omNs);name.setText(bean.getSname();item.addChild(name);sex = fac.createOMElement(sex, omNs);sex.setText(bean.getSsex();item.addChild(sex);birthday = fac.createOMElement(birthday, omNs);birthday.setText(bean.getSbirthday().toString();item.addChild(birthday);address = fac.createOMElement(address, omNs);address.setText(bean.getSaddress();item.addChild(address); session.close();return element;(4).构建Bean类(src/service/student/bean/StudentBean.java)代码：package service.student.bean;import java.util.Date;public class StudentBean private Integer sid;private String sname;private String ssex;private Date sbirthday;private String saddress;public Integer getSid() return sid;public void setSid(Integer sid) this.sid = sid;public String getSname() return sname;public void setSname(String sname) this.sname = sname;public String getSsex() return ssex;public void setSsex(String ssex) this.ssex = ssex;public Date getSbirthday() return sbirthday;public void setSbirthday(Date sbirthday) this.sbirthday = sbirthday;public String getSaddress() return saddress;public void setSaddress(String saddress) this.saddress = saddress;(5).构建MyBatis映射(src/service/student/mapper/StudentMapper.xml)： (6).配置services.xml，即在WebRoot/META-INF/services.xml This is a sample Flower Web Service. service.flower.FlowerService This is a sample Student Web Service. service.student.StudentService 这个文件中包括两个服务，用可以实现。其中service.StudentService，service是包名，StudentService是编绎成.class的类文件。studentAdd，studentEdit，studentDel，studentQuery，studentList为类中的方法名。RawXMLINOnlyMessageReceiver是只传入参数而不返回数据，RawXMLINOutMessageReceiver是传入同时返回参数，默认为后者。(7).在项目中的build中新建文件example，将META-INF/services.xml(连包META-INF一起拷贝)，build/classes包中的service整个包与Configuration.xml拷贝到example内。打开Dos命令窗口，用cd 退出当前路径，(换盘符用f:)，用cd 文件名Flowerbuild，将example内的文件打包成.aar格式，jar cvf TestService.aar . 注意一定要有后面这个点。文件结构图如下所示(在example下的文件)：最后将Flower/build/classes中的service包和Configuration.xml拷贝到%tomcat6%webapps/axis2/WEB-INF/classes，即上图中的service包和Configuration.xml。文件组织图如下所示：(8).将这个包发布到Tomcat上，即上传。3.client端设计(1). 新增一条记录(src/client/student/StudentAdd.java)：package client.student;import org.apache.axiom.om.OMAbstractFactory;import org.apache.axiom.om.OMElement;import org.apache.axiom.om.OMFactory;import org.apache.axiom.om.OMNamespace;import org.apache.axis2.addressing.EndpointReference;import org.apache.axis2.client.Options;import org.apache.axis2.client.ServiceClient;public class StudentAdd private static EndpointReference targetEPR = new EndpointReference(http:/localhost:8080/axis2/services/StudentService);public static OMElement getMessageOMElement() OMFactory fac = OMAbstractFactory.getOMFactory();OMNamespace omNs = fac.createOMNamespace(/,student);OMElement method = fac.createOMElement(studentAdd, omNs);OMElement item = fac.createOMElement(item, omNs);

address.setText(香港); item.addChild(address); method.addChild(item);return method;public static void main(String args) try Options options = new Options();options.setTo(targetEPR);ServiceClient sender = new ServiceClient();sender.setOptions(options);OMElement bean = StudentAdd.getMessageOMElement();sender.fireAndForget(bean); catch (Exception axisFault) axisFault.printStackTrace();(2). 修改一条历史记录(src/client/student/StudentEdit.java)：package client.student;import org.apache.axiom.om.OMAbstractFactory;import org.apache.axiom.om.OMElement;import org.apache.axiom.om.OMFactory;import org.apache.axiom.om.OMNamespace;import org.apache.axis2.addressing.EndpointReference;import org.apache.axis2.client.Options;import org.apache.axis2.client.ServiceClient;public class StudentEdit private static EndpointReference targetEPR = new EndpointReference(http:/localhost:8080/axis2/services/StudentService);public static OMElement getMessageOMElement() OMFactory fac = OMAbstractFactory.getOMFactory();OMNamespace omNs = fac.createOMNamespace(/,student);OMElement method = fac.createOMElement(studentEdit, omNs);OMElement item = fac.createOMElement(item, omNs);
