我在基於Spring框架的Java應用程序上升級P6SPY。 當前的p6spy版本是2.1.4，我們至少需要版本3.0.0（或3.2.0）。p6spy 3.x配置（避免在類com.p6spy.engine.wrapper.ConnectionWrapper中沒有可見的構造函數）
當我在pom.xml和部署的應用程序中更改了版本後，出現了一些AOP錯誤。
No visible constructors in class com.p6spy.engine.wrapper.ConnectionWrapper
我們而言configuation是：
<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" />

一些錯誤配置？我已經搜索了這個問題，什麼都沒發現。
過了一段時間，我意識到什麼可能是一個問題。 我們使用這個類作爲看點：
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;
}
}
的一點是，我們需要知道，哪些用戶在做數據庫的一些動作。每次獲得連接時拋出異常。 有沒有另一種方法如何讓這個工作？ 的例外是：

在p6spy 2.1.4版中，沒有出現問題 – Worsik
可以通過JdbcEventListener而不是Aspect類來完成嗎？ https://github.com/p6spy/p6spy/blob/master/src/main/java/com/p6spy/engine/event/JdbcEventListener.java – Worsik
