Hey there if you want to know how to get user details in Jhipster . Check this

1. First import UserService in your class

2. Then declare variable

Private UserService userService

3. Initialize in constructor

class_constructor( UserService userService){
this.userService = userService;
}

4. Then You can access details like this using getter values

userService.getUserWithAuthorities().get().fieldName()

For Id : userService.getUserWithAuthorities().get().getId()
For Name : userService.getUserWithAuthorities().get().getFirstName()
userService.getUserWithAuthorities().get().getLastName()
For Email : userService.getUserWithAuthorities().get().getEmail()
For Username(login) : userService.getUserWithAuthorities().get().getlogin()

This way you can access current logged in user Details.

You can use these values by setting directly or creating variables:

String userEmail = userService.getUserWithAuthorities().get().getEmail()
