Hessian实现C#语言开发winforms前端+sshj2ee后台服务(一、服务器端)

大家好，最近实现一个项目需要用到Hessian，麻烦用过Hessian的朋友能帮我看看为什么测试服务调不出服务器端的实体类

首先是客户端，创建实体Bean

?

public class PosInfo implements java.io.Serializable {private static final long serialVersionUID = 4791943343138808983L;private String posid;private String posname;private String lmodifydate;public String getPosid() {return posid;}public void setPosid(String posid) {this.posid = posid;}public String getPosname() {return posname;}public void setPosname(String posname) {this.posname = posname;}public String getLmodifydate() {return lmodifydate;}public void setLmodifydate(String lmodifydate) {this.lmodifydate = lmodifydate;}}

?

?

接下来创建Hessian服务的接口

?

?

public interface IPosService {public void savePosition(PosVO vo);public void updatePosition(PosVO vo);public PosInfo queryPositionById(String posId);public void deletePosition(String posId);public List queryPositions();public String test(String s);public List find(String arg0);}

?

接下来是实现了接口的服务类

?

public class PosServiceImpl implements IPosService {private static final Log log = LogFactory.getLog(PosServiceImpl.class);// private BaseDAO dao;////// public BaseDAO getDao() {// return dao;// }//// public void setDao(BaseDAO dao) {// this.dao = dao;// }// BeanFactory factory = new ClassPathXmlApplicationContext(// "classpath:applicationContext.xml");// PosDAO dao = (PosDAO) factory.getBean("posDAO");//// ApplicationContext context = new ClassPathXmlApplicationContext(// "classpath:application-position.xml");// PosDAO dao = (PosDAO) context.getBean("posDAO");//private PosDAO dao;public PosDAO getDao() {return dao;}public void setDao(PosDAO dao) {this.dao = dao;}private JdbcTemplate jdbcTemplate;public JdbcTemplate getJdbcTemplate() {return jdbcTemplate;}public void setJdbcTemplate(JdbcTemplate jdbcTemplate) {this.jdbcTemplate = jdbcTemplate;}public List find(String arg0) {List list = dao.find(arg0);return list;}public void savePosition(PosVO vo) {log.info("add new instance");SimpleDateFormat sdf = new SimpleDateFormat("yyyyMMddhhmmss");PosInfo pos = new PosInfo();pos.setPosname(vo.getPosname());pos.setLmodifydate(sdf.format(new Date()).toString());log.info("now begin save");dao.save(pos);log.info("add success !");}public void updatePosition(PosVO vo) {SimpleDateFormat sdf = new SimpleDateFormat("yyyyMMddhhmmss");PosInfo pos = this.queryPositionById(vo.getPosid());pos.setPosname(vo.getPosname());pos.setLmodifydate(sdf.format(new Date()).toString());dao.update(pos);}public PosInfo queryPositionById(String posId) {return (PosInfo) dao.get(PosInfo.class, posId);}public void deletePosition(String posId) {PosInfo pos = this.queryPositionById(posId);dao.delete(pos);}public List queryPositions() {List poses = dao.find("from PosInfo po order by po.lmodifydate desc");return poses;}public String test(String s) {log.info("===========进入service层");return dao.test(s);}}

?

?

还有service层引用的DAO层

?

public class PosDAO extends BaseDAO {private static final Log log = LogFactory.getLog(PosDAO.class);protected void initDao() {// do nothing}public void delete(Object arg0) throws DataAccessException {// TODO Auto-generated method stubsuper.delete(arg0);}public List find(String arg0) throws DataAccessException {// TODO Auto-generated method stubreturn super.find(arg0);}public Object get(Class arg0, Serializable arg1)throws ObjectRetrievalFailureException, DataAccessException {// TODO Auto-generated method stubreturn super.get(arg0, arg1);}public void save(Object arg0) throws DataAccessException {// TODO Auto-generated method stubsuper.save(arg0);}public void update(Object arg0) throws DataAccessException {// TODO Auto-generated method stubsuper.update(arg0);}public List<PosInfo> getAllPosInfo() {return (List<PosInfo>) super.find("from PosInfo");}public String test(String s) {log.info("hessian测试");return s+"成功";}}

?

spring 的配置文件在此省略，没什么好说的了

?

然后是web.xml的配置

?

<servlet><servlet-name>dispatcher</servlet-name><servlet-class><!--  com.caucho.hessian.server.HessianServlet -->org.springframework.web.servlet.DispatcherServlet</servlet-class><!--  <init-param><param-name>service-class</param-name><param-value>com.*.*.*.service.impl.PosServiceImpl</param-value></init-param>--><load-on-startup>0</load-on-startup></servlet><servlet-mapping><servlet-name>dispatcher</servlet-name><url-pattern>/remote/*</url-pattern></servlet-mapping>

?

?

?

还要配置dispatcher-servlet.xml

?

<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd"><beans><bean id="dataSource"/></property><property name="hibernateProperties"><props><prop key="hibernate.dialect">org.hibernate.dialect.SybaseDialect</prop><prop key="hibernate.show_sql">true</prop></props></property><property name="mappingDirectoryLocations"><list><value>classpath:/com/*/*/*/domain/</value></list></property></bean><bean id="dao" ref="sessionFactory"></property></bean><bean id="iPosService"/></property></bean><bean name="/HessianService"ref="iPosService"></property><property name="serviceInterface"value="com.*.*.*.service.IPosService" /></bean></beans>
