What tool can I use to evaluate the response time of a request (jdbc)

Ex:

query = "SELECT * FROM v$version WHERE banner LIKE '%Oracle%'";
ResultSet rs = stmt.executeQuery(query);
// linha de cima ⋀ 
// quanto tempo demorou nesse meio ?
// linha de baixo ⋁
rs.next();

No log appears

15:58:35.175 INFO - 6. SELECT * FROM v$version WHERE banner LIKE '%Oracle%'; {executed in 1 ms}

In fact the query was executed with 1ms but there is a gap between executing the query and loading this information.

What tool can I use to get this information?

java jdbc time

There are some commercial tools that can do this, but I've never used them.

In essence, you should measure the time elapsed in the% method call and related methods.

What is usually done in the companies where I worked is instrumentalize the instances of executeQuery , Connection and correlates to measure the times. Unfortunately each has a solution.

Here at Atlassian we have a plugin for JIRA that, when loaded, is able to modify classes at runtime and thus collect profiling information.

This is done using a java agent , which makes it possible to add instrumentation to classes. See the Java documentation for more details.

There is a tutorial on how to make a mini profiler using instrumentation here . p>

The simplest alternative is to simply inject your summer from Statement and related classes into the other classes of your system, as I mentioned above.
