How to allow a User only access their own data in Spring Boot / Spring Security?

spring boot rest api role based security
spring boot security roles and permissions from database
spring security user
spring security get user role in controller
spring oauth2 role based authorization
spring boot user management
role based access control in java web application example
spring security dynamic roles

I have some rest api like this:

/users/{user_id}
/users/{user_id}/orders
/users/{user_id}/orders/{order_id}

How I must secure them? every user must see only her/his data, But admin can see all of them.

How & What I must implement in Spring Security that User by Id == 1 can't see data of user by Id == 2 and vice versa, expect users by role admin that can see all?

Do I check before every method User Id in session is equail with user_id param passed to api? is there a better way?

p.s: I use JWT by spring security.

In a @Controller, @RestController annotated bean you can use Principal directly as a method argument.

    @RequestMapping("/users/{user_id}")
    public String getUserInfo(@PathVariable("user_id") Long userId, Principal principal){
        // test if userId is current principal or principal is an ADMIN
        ....
    }

If you don't want the security checks in your Controllers you could use Spring EL expressions. you probably already use some built-in expressions like hasRole([role]). but you could write your own expressions.

Create a bean

public class UserSecurity {
     public boolean hasUserId(Authentication authentication, Long userId) {
        // do your check(s) here
    }
}

Use your expression

http
 .authorizeRequests()
 .antMatchers("/user/{userId}/**")
      .access("@userSecurity.hasUserId(authentication,#userId)")
    ...

and you can combine expressions like

hasRole('admin') or @userSecurity.hasUserId(authentication,#userId)

Spring Security Role Based Access Authorization Example , Spring Security Roles, Spring security role based access, spring security role How to allow a User only access their own data in Spring Boot / Spring Security? If Spring Security finds the header, it starts the authentication. To authenticate, Spring Security needs user data with user names and password hashes. That’s why we have to implement the UserDetailsService interface. This interface loads user-specific data and needs read-only access to user data:

You can also use @PreAuthorize on the service interface. If you have a custom userdetails object then you can do it easily. In one of my projects I did it like this:

@PreAuthorize(value = "hasAuthority('ADMIN')"
        + "or authentication.principal.equals(#post.member) ")
void deletePost(Post post);

BTW this is in a service interface. You have to make sure to add the right annotations to get preauthorize to work.
