Je suis en train de mettre à jour P6SPY sur nos applications Java basées sur Spring framework. La version actuelle de p6spy est 2.1.4 et nous voulons au moins la version 3.0.0 (ou 3.2.0).Configuration p6spy 3.x (éviter Aucun constructeur visible dans la classe com.p6spy.engine.wrapper.ConnectionWrapper)
Après avoir modifié la version dans pom.xml et l'application déployée, certaines erreurs AOP sont apparues.
No visible constructors in class com.p6spy.engine.wrapper.ConnectionWrapper
Notre contexte configuation est:
<jee:jndi-lookup id="myDataSource" jndi-name="jdbc/ourDS" resource-ref="true"/>
<bean id="monitoringDataSource" class="com.p6spy.engine.spy.P6DataSource">
<constructor-arg ref="myDataSource" />

un problème avec la configuration? J'ai cherché ce problème et n'ai rien trouvé. Après un moment, j'ai réalisé ce qui pourrait être un problème. Nous utilisons cette classe comme Aspect:
package mypackage.db.aspect;
import mypackage.db.security.SecurityHolder;
import java.lang.reflect.Method;
import java.sql.CallableStatement;
import java.sql.Connection;
import java.sql.SQLException;
import org.aspectj.lang.ProceedingJoinPoint;
import org.aspectj.lang.annotation.Around;
import org.aspectj.lang.annotation.Aspect;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.aop.MethodBeforeAdvice;
import org.springframework.aop.aspectj.AspectJExpressionPointcutAdvisor;
import org.springframework.aop.framework.ProxyFactory;
import org.springframework.stereotype.Component;
@Component
@Aspect
public class ClientIdentifierAspect {
private static Logger log = LoggerFactory.getLogger(ClientIdentifierAspect.class);
@Around("execution(* javax.sql.DataSource.getConnection(..))")
public Connection onNewConnection(final ProceedingJoinPoint pjp) throws Throwable {
Connection connection = (Connection) pjp.proceed(pjp.getArgs());
if (connection != null) {
String loginName = SecurityHolder.getOwner() != null ? SecurityHolder.getOwner().getLoginName() : "";
//loginName = loginName.replaceAll("'", "''");
try (CallableStatement cs = connection.prepareCall("{ call DBMS_SESSION.SET_IDENTIFIER(?) }")) {
cs.setString(1, loginName);
cs.execute();
// proxy trida pro smazani identifieru pri uzavirani spojeni
// viz https://beautifulbytes.wordpress.com/2013/01/21/use-spring-aop-and-jmx-to-monitor-and-cancel-jdbc-statements/
ProxyFactory factory = new ProxyFactory();
factory.setProxyTargetClass(true);
factory.setTarget(connection);
AspectJExpressionPointcutAdvisor aspectJExpressionPointcutAdvisor = new AspectJExpressionPointcutAdvisor();
aspectJExpressionPointcutAdvisor.setExpression("execution (* java.sql.Connection.close(..))");
aspectJExpressionPointcutAdvisor.setAdvice(new MethodBeforeAdvice() {
@Override
public void before(Method method, Object[] args, Object target) throws Throwable {
Connection con = (Connection) target;
try (CallableStatement cs = con.prepareCall("{ call DBMS_SESSION.CLEAR_IDENTIFIER() }")) {
cs.execute();
} catch (SQLException ex) {
throw ex;
}
}
}
);
factory.addAdvisor(aspectJExpressionPointcutAdvisor);
ClassLoader contextClassLoader = Thread.currentThread().getContextClassLoader();
connection = (Connection) factory.getProxy(contextClassLoader);
} catch (SQLException ex) {
throw ex;
} catch (Exception ex) {
log.error("", ex);
}
}
return connection;
}
}
Le point est que nous devons savoir, quel utilisateur a fait une action dans la base de données. Une exception est levée à chaque fois que la connexion est obtenue. Existe-t-il un autre moyen de le faire fonctionner? Exception est:
ERROR mypackage.db.aspect.ClientIdentifierAspect-

Dans la version 2.1.4 de p6spy, aucun problème n'apparaît – Worsik
Cela pourrait-il être fait par JdbcEventListener au lieu de la classe Aspect? https://github.com/p6spy/p6spy/blob/master/src/main/java/com/p6spy/engine/event/JdbcEventListener.java – Worsik
