More importantly, we’ll try to understand the reasons for Spring being our framework of choice. Details of Spring and its constituent parts have beenwidely covered in our previous tutorials. Hence we’ll skip the introductory “how” parts and mostly focus on “why”s. 2. Why Use Any Fram...
Finally, it's completely unrelated to how we use logs,e.g.: varlogger=// Obtain loggerlogger.info("My message with parameters {}, {}",foo,bar); Regular logging on steroids To use the above statement, we need to choose a logging implementation. Because I'm more familiar with it, I'...
yes, spring security can be complex, from the more advanced functionality within the core to the deep oauth support in the framework. i built the security material as two full courses - core and oauth , to get practical with these more complex scenarios. we explore when and how to use ...
First we have to check whether thetestcreated already in instance or not. If we hadinitialised the spy with a real object(because e.g. we have a complex constructor or whatever other reason), Mockito would usethis existing instance.

When a header like "Bad-header: xxxxxxxxxxxxxxx\x10" is received, it will cause the regular expression engine to catastrophically backtrack causing the process to use 100% CPU time and blocking any other interactions. This allows an attacker to send a single request with an invalid header and...
