春天使用的身份验证的区别在哪里

Question

我不知道使用AuthorizationServerConfigurerAdapter和UsernamePasswordAuthenticationFilter创建JWT之间有什么区别

这是用于春季靴2

带有AuthorizationServerConfigurerAdapter的示例

` @组态 @EnableAuthorizationServer 公共类AuthorizationServerConfig扩展了AuthorizationServerConfigurerAdapter {

@Autowired
private BCryptPasswordEncoder passwordEncoder;

@Autowired
private AuthenticationManager authenticationManager;

@Autowired
private InfoAdicionalToken infoAdicionalToken;

@Override
public void configure(AuthorizationServerSecurityConfigurer security) throws Exception {
    security.tokenKeyAccess("permitAll()")
    .checkTokenAccess("isAuthenticated");
}

@Override
public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
    clients
            .inMemory()
            .withClient("my_app")
            .secret(passwordEncoder.encode("secret"))
            .scopes("read", "write")
            .authorizedGrantTypes("password", "refresh_token")
            .accessTokenValiditySeconds(3600)
            .refreshTokenValiditySeconds(3600);
}

@Override
public void configure(AuthorizationServerEndpointsConfigurer endpoints) throws Exception {
    TokenEnhancerChain tokenEnhancerChain = new TokenEnhancerChain();
    tokenEnhancerChain.setTokenEnhancers(Arrays.asList(infoAdicionalToken, accessTokenConverter()));

    endpoints.authenticationManager(authenticationManager)
            .tokenStore(tokenStore())
            .accessTokenConverter(accessTokenConverter())
            .tokenEnhancer(tokenEnhancerChain);
}

@Bean
public JwtTokenStore tokenStore() {
    return new JwtTokenStore(accessTokenConverter());
}

@Bean
public JwtAccessTokenConverter accessTokenConverter(){
    JwtAccessTokenConverter jwtAccessTokenConverter = new JwtAccessTokenConverter();
    jwtAccessTokenConverter.setSigningKey(JwtConfig.RSA_PRIVATE);
    jwtAccessTokenConverter.setVerifierKey(JwtConfig.RSA_PUBLIC);
    return jwtAccessTokenConverter;
}

} `

并带有UsernamePasswordAuthenticationFilter

` 公共类JWTAuthenticationFilter扩展了UsernamePasswordAuthenticationFilter {

// We use auth manager to validate the user credentials
private AuthenticationManager authManager;

private final JwtConfig jwtConfig;

public JWTAuthenticationFilter(AuthenticationManager authManager, JwtConfig jwtConfig) {
    this.authManager = authManager;
    this.jwtConfig = jwtConfig;

    // By default, UsernamePasswordAuthenticationFilter listens to "/login" path.
    // In our case, we use "/auth". So, we need to override the defaults.
    this.setRequiresAuthenticationRequestMatcher(new AntPathRequestMatcher(jwtConfig.getUri(), "POST"));
}

@Override
public Authentication attemptAuthentication(HttpServletRequest request, HttpServletResponse response)
        throws AuthenticationException {

    try {

        // 1. Get credentials from request
        User user = new ObjectMapper().readValue(request.getInputStream(), User.class);

        // 2. Create auth object (contains credentials) which will be used by auth manager
        UsernamePasswordAuthenticationToken authToken = new UsernamePasswordAuthenticationToken(
                user.getUsername(), user.getPassword(), Collections.emptyList());

        // 3. Authentication manager authenticate the user, and use UserDetialsServiceImpl::loadUserByUsername() method to load the user.
        return authManager.authenticate(authToken);

    } catch (IOException e) {
        throw new RuntimeException(e);
    }
}

// Upon successful authentication, generate a token.
// The 'auth' passed to successfulAuthentication() is the current authenticated user.
@Override
protected void successfulAuthentication(HttpServletRequest request, HttpServletResponse response, FilterChain chain,
                                        Authentication auth) throws IOException, ServletException {

    Long now = System.currentTimeMillis();
    String token = Jwts.builder()
            .setSubject(auth.getName())
            // Convert to list of strings.
            // This is important because it affects the way we get them back in the Gateway.
            .claim("authorities", auth.getAuthorities().stream()
                    .map(GrantedAuthority::getAuthority).collect(Collectors.toList()))
            .setIssuedAt(new Date(now))
            .setExpiration(new Date(now + jwtConfig.getExpiration() * 1000))  // in milliseconds
            .signWith(SignatureAlgorithm.HS512, jwtConfig.RSA_PRIVATE)
            .compact();
    // Add token to header
    response.addHeader(jwtConfig.getHeader(), jwtConfig.getPrefix() + token);
}

} `

AuthorizationServerConfigurerAdapter是Oauth2吗？
