SpringBoot Security Oauth2 role and permission authentication annotation method hasRole and hasAuthority use difference

SpringBoot Security set permission test results

ADMIN2,ROLE_ADMIN

String[] permissions = "ADMIN2,ROLE_ADMIN".split(",");
List<GrantedAuthority> authorities = new ArrayList<>();
for (String permission : permissions) {
    authorities.add(new SimpleGrantedAuthority(permission));
}
userDetails.setAuthorities(authorities);

Add the method annotation permission test result on the controller:

@PreAuthorize("hasRole('ADMIN')")                //允许
@PreAuthorize("hasRole('ROLE_ADMIN')")           //允许
@PreAuthorize("hasRole('ADMIN2')")               //不允许
@PreAuthorize("hasRole('ROLE_ADMIN2')")          //不允许
@PreAuthorize("hasAuthority('ADMIN2')")          //允许
@PreAuthorize("hasAuthority('ROLE_ADMIN2')")     //不允许
@PreAuthorize("hasAuthority('ADMIN')")           //不允许
@PreAuthorize("hasAuthority('ROLE_ADMIN')")      //允许

The test shows:

Add the prefix ROLE_ to verify permissions in three ways:

@PreAuthorize("hasRole('ADMIN')")                //允许
@PreAuthorize("hasRole('ROLE_ADMIN')")           //允许
@PreAuthorize("hasAuthority('ROLE_ADMIN')")      //允许

There is only one way to verify permissions without increasing ROLE_:

@PreAuthorize("hasAuthority('ADMIN2')")          //允许
