Typing qe to enter the focused mode of QLExpress.

Executing Java Code

for math example: Math.sin(9);

qe_math

Running result: 0.4121184852417566.

for reading system environment variables example: top.myrest.myflow.util.Jackson.INSTANCE.toJsonString(System.getenv(), true);

qe_system.png

Of course, you can also format it as yaml: top.myrest.myflow.util.Jackson.INSTANCE.toYamlString(System.getenv());.

Verifying Methods

Sometimes, because some tooling classes have so many methods, and you are not sure which one to use, so we need to verify the execution result of the method, for example:

qe_hutool
