This is the 10th day of my participation in the August More Text Challenge

preface

We know that in the project development, background development authority authentication is very important, Springboot commonly familiar authority authentication framework, Shiro, and is springboot family bucket security of course, they each have their own benefits, But I prefer springBoot’s built-in authorization framework

<! Springboot permission authentication -->
      <dependency>
          <groupId>org.springframework.boot</groupId>
          <artifactId>spring-boot-starter-security</artifactId>
      </dependency>
Copy the code

Natural integration with Springboot, powerful

Quick learning

The main implementation of Spring Security Security authentication, combined with RESTful API style, using stateless environment.

The main implementation is through the URL of the request, through the filter to do different authorization policy operations, provide a method of authentication for the request, and then authentication, authorization successfully returned to the authorization instance information for service invocation.

Token-based authentication is performed as follows:

A user sends requests using a user name and password. Program validation. The program returns a signed token to the client. The client stores tokens and uses them each time to send a request. The server validates the token and returns data. Every request requires a token, so every request authenticates the user, so you have to use caching,

Generate JWT toke

I wrote a utility class JwtTokenUtil to generate JWT Toke

public class JwtTokenUtil implements Serializable {

    private static final long serialVersionUID = -2550185165626007488L;

    private String secret="TcUF7CC8T3txmfQ38pYsQ3KY";

        return getClaimFromToken(token, Claims::getSubject);

    public Boolean validateToken(String token, UserDetails userDetails) {

Injection data source

Spring Security provides the UserDetailsService interface for user authentication, and the UserDetails entity class for storing user information, (user credentials, Permissions, etc.)

Look at the source code

package org.springframework.security.core.userdetails;

public interface UserDetailsService {
    UserDetails loadUserByUsername(String var1) throws UsernameNotFoundException;
}
Copy the code

package org.springframework.security.core.userdetails;
public interface UserDetails extends Serializable {
    Collection<? extends GrantedAuthority> getAuthorities();

    String getPassword(a);

    String getUsername(a);

    boolean isAccountNonExpired(a);

    boolean isAccountNonLocked(a);

    boolean isCredentialsNonExpired(a);

    boolean isEnabled(a);
}
Copy the code

So we divided it into two steps:

Note that the User account is locked when logging in to the User

Because when the user entity class implements the UserDetails interface, I automatically implement all the abstract methods, and automatically generate the following four methods, which return false by default,

    @Override
    public boolean isAccountNonExpired(a) {
        return false;
    }
 
    @Override
    public boolean isAccountNonLocked(a) {
        return false;
    }
 
    @Override
    public boolean isCredentialsNonExpired(a) {
        return false;
    }
 
    @Override
    public boolean isEnabled(a) {
        return false;
    }
Copy the code

That’s why, just change their return value to true.

An explanation of several fields in UserDetails:

// Returns the authentication user password, or NULL if it cannot be returned

String getPassword();
String getUsername();
Copy the code

The account is expired. Expiration cannot be verified

boolean isAccountNonExpired();
Copy the code

Specifies whether the user is locked or unlocked. The locked user cannot be authenticated

Boolean isAccountNonLocked ();Copy the code

Credentials (password) indicating whether the user has expired. Expired credentials prevent authentication

boolean isCredentialsNonExpired();
Copy the code

Disabled users cannot be authenticated

boolean isEnabled();
Copy the code

Implementation interfaceloadUserByUsernameMethods inject data validation

Its own IUserService user interface class inherits Spring Security to provide the UserDetailsService interface

public interface IUserService  extends IService<User>, UserDetailsService {

    User getUserByUsername(String username);

   / * * //** * Obtain all user permissions **@param username
     * @return* //* Set
      
        getUserPerms(String username); * /
      

}
Copy the code

And implement it

@Service
@RequiredArgsConstructor
@Slf4j
public class UserServiceImpl extends ServiceImpl<UserMapper.User> implements IUserService {
    private final RoleMapper roleMapper;

    @Override
    public User getUserByUsername(String username) {
        return this.baseMapper.selectOne(new QueryWrapper<User>().lambda()
                .eq(User::getUsername, username));
    }


    /** ** when authenticating user details provided by the user@param username
     * @return
     * @throws UsernameNotFoundException
     */
    @Override
    public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
        User user = this.getUserByUsername(username);

        if (StrUtil.isBlankIfStr(user)) {
            throw new UsernameNotFoundException("User not found with username: " + username);
        }

        // Get user role information
        List<Role> roles = roleMapper.findUserRolePermsByUserName(username);
        user.setRoles(roles);

        List<String> permList = this.baseMapper.findUserPerms(username);

        / / java8 stream is very convenient
        Set<String> perms = permList.stream().filter(o->StrUtil.isNotBlank(o)).collect(Collectors.toSet());
        user.setPerms(perms);

        // Used to add user permissions. Just add user rights to authorities and you'll be fine.
        // List<SimpleGrantedAuthority> authorities = new ArrayList<>();


        // Used to add user permissions. Just add user rights to authorities and you'll be fine.
        /*for (Role role : roles) { authorities.add(new SimpleGrantedAuthority(role.getRolePerms())); log.info("loadUserByUsername: " + user); } * /
        //user.setAuthorities(authorities); // Used for the value of the @authenticationPrincipal tag at login
        returnuser; }}Copy the code

The loadUserByUsername implementation authenticates the user name and password from the database and obtains user role permission information
