通过从Scala/Java编写/执行SQL脚本处理间歇性数据库连接

public class ConnectionProxy {

    public ConnectionProxy(Object anObject) {
        super(anObject);
    }

    @Override
    public Object invoke(Object proxy, Method method, Object[] args) throws Throwable {              
        Object result = method.invoke(target, args);
        String methodName = method.getName();

        if (methodName.equals("createStatement")) {
            result = ProxyBuilder.createProxy(result, new StatementProxy(result));
        }

        return result;
    }
} 

为了拦截任何对 Statement.execute(String sql) :

public class StatementProxy {

    public StatementProxy(Object anObject) {
        super(anObject);
    }

    @Override
    public Object invoke(Object proxy, Method method, Object[] args) throws Throwable {               
       try {
           return method.invoke(proxy, args);
       } catch (SQLException sqle) {
           if (method.getName().contains("execute")) {
              String sql = "";

              if (args != null && args[0] != null) {
                  sql = args[0].toString();
              }

              saveToFile(arg);
           }

           throw sqle;   
        }
    }
}

public final class ProxyBuilder {

    public static Connection tracingConnection(Connection connection) {
        return createProxy(connection, new ConnectionProxy(connection));
    }

    static <T> T createProxy(T anObject, InvocationHandler invocationHandler) {
        return createProxy(anObject, invocationHandler, anObject.getClass().getInterfaces());
    }

    static <T> T createProxy(T anObject, InvocationHandler invocationHandler, Class... forcedInterfaces) {
        return (T) Proxy.newProxyInstance(
            anObject.getClass().getClassLoader(),
            forcedInterfaces,
            invocationHandler);
        }
}

当然 这不是您的最终生产代码
