I have a interface:
public interface SealQueryService {
public boolean isSealExist(String domainName) throws Exception;
}
and implemented as follow:
public class SealQueryServiceImpl extends HibernateGenericDao implements
SealQueryService {
public boolean isSealExist(String domainName) throws Exception {
String sealByDomainHQL = "from Seal seal where
seal.domainName1=? or
seal.domainName2 = ?";
List sealByDomainList = this.find(sealByDomainHQL, domainName,
domainName);
return sealByDomainList != null && sealByDomainList.size() > 0;
}
}
seal-servlet.xml configuration:
<bean id="sealQuery"
class="cn.cnnic.seal.service.SealQueryServiceImpl" />
<bean name="/seal.service"
class="org.springframework.remoting.caucho.HessianServiceExporter">
<property name="service">
<ref bean="sealQuery" />
</property>
<property name="serviceInterface">
<value>cn.cnnic.seal.service.SealQueryService</value>
</property>
</bean>
web.xml configuration:
<servlet>
<servlet-name>seal</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>seal</servlet-name>
<url-pattern>/seal.service</url-pattern>
</servlet-mapping>
when I test from the following code:
public class SealQueryTest {
public static void main(String[] args) throws Exception
{
String url = "http://218.241.108.134:8088/seal/seal.service";;
HessianProxyFactory factory = new HessianProxyFactory();
factory.setDebug(true);
SealQueryService s = (SealQueryService) factory.create(
SealQueryService.class, url);
System.out.println("call Hessian service: " +
s.isSealExist("www.sina.com.cn"));
}
}
I get error:

I cannot figure out what's wrong. I write another service implementation with
pure
jdbc as follows:
public class SealQueryServiceJdbcImpl implements SealQueryService {
private static final Logger log =
Logger.getLogger(SealQueryServiceJdbcImpl.class);
public boolean isSealExist(String domainName) throws Exception {
InputStream in =
this.getClass().getResourceAsStream("/jdbc/jdbc-sl-registry.properties");
Properties prop = new Properties();
Connection conn = null;
PreparedStatement cstmt = null;
ResultSet rs = null;
try {
prop.load(in);
Class.forName(prop.getProperty("jdbc.sl.driverClassName"));
conn =
DriverManager.getConnection(prop.getProperty("jdbc.sl.url"),
prop.getProperty("jdbc.sl.username"), prop.getProperty("jdbc.sl.password"));
String sql = "select * from sl_reg_seal s where
s.domainName1=? or
s.domainName2 = ?";
cstmt = conn.prepareStatement(sql);
cstmt.setString(1, domainName);
cstmt.setString(2, domainName);
rs = cstmt.executeQuery();
if(rs.next()) return true;
} catch (IOException e) {
log.error("load jdbc properties error!", e);
} catch (ClassNotFoundException e) {
log.error("load jdbc driver error!", e);
} catch (SQLException e) {
log.error("exec procedure error",e);
} finally {
try {
if(cstmt != null) {
cstmt.close();
}
if(conn != null) {
conn.close();
}
}catch(SQLException e) {
log.error("sql error",e);
}
}
return false;
}
}
then the test code works. So I guess hessian cannot work well with hibernate.
Any help is appreciated:)
