Spring Security JWT 过滤器适用于所有请求

Question

我正在开发一个 Spring Boot 服务，它正在接收请求标头中另一个服务中生成的 JWT 令牌。 我的目标是在我的 Spring Boot 应用程序中验证 JWT 令牌的有效性。

经过一段时间的研究，我决定使用 Spring Security 的 WebSecurityConfig 并拥有某种实际上是过滤器的中间件。

我已将过滤器配置为不适用于我的应用程序中定义的所有请求。但无论如何，过滤器都会应用于配置为 permitAll() 的请求。

我完全被这一切弄糊涂了，不知道我错过了什么。最后我决定寻求帮助。请帮忙。

这是我的代码。

安全配置：

@Configuration
@EnableWebSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
@Autowired
JWTAuthenticationFilter jwtAuthenticationFilter;

@Override
protected void configure(HttpSecurity http) throws Exception {
    http
        .csrf().disable()
        .authorizeRequests()
            .antMatchers("/").permitAll()
            .antMatchers("/req").permitAll()
            .and()
        .authorizeRequests()
            .anyRequest().authenticated()
            .and()
        // And filter other requests to check the presence of JWT in header
        .addFilterBefore(jwtAuthenticationFilter,
                BasicAuthenticationFilter.class);
}

@Override
public void configure(WebSecurity webSecurity) {
    webSecurity
        .ignoring()
            .antMatchers("/req");
    }
}

过滤器：

@Component
public class JWTAuthenticationFilter extends GenericFilterBean {
@Autowired
TokenAuthenticationService tokenAuthenticationService = new TokenAuthenticationService();
@Override
public void doFilter(ServletRequest request,
        ServletResponse response,
        FilterChain filterChain)
                throws IOException, ServletException {
    boolean authentication = tokenAuthenticationService
            .getAuthentication((HttpServletRequest)request);

    if (!authentication) {
        ((HttpServletResponse) response).setStatus(HttpServletResponse.SC_UNAUTHORIZED);
        return;
    }

    filterChain.doFilter(request,response);
    }
}

身份验证服务：

@Component
class TokenAuthenticationService {
@Value("${security.authentication.token.secret}")
private String SECRET;
@Value("${security.authentication.token.token_prefix}")
private String TOKEN_PREFIX;
@Value("${security.authentication.token.header_string}")
private String HEADER_STRING;

boolean getAuthentication(HttpServletRequest request) throws UnsupportedEncodingException {
    String token = request.getHeader(HEADER_STRING);

    if (token != null) {
        // parse the token.
        DecodedJWT jwt;
        try {
            Algorithm algorithm = Algorithm.HMAC256(SECRET);
            JWTVerifier verifier = JWT.require(algorithm)
                .build(); //Reusable verifier instance
            jwt = verifier.verify(token);

            return true;
        } catch (UnsupportedEncodingException exception){
            //UTF-8 encoding not supported
            UnsupportedEncodingException ex = exception;
            return false;
        } catch (JWTVerificationException exception){
            //Invalid signature/claims
            JWTVerificationException ex = exception;
            return false;
        }
    }
    return false;
    }
}

您需要使用 ResourceServiceConfiguration 类而不是 WebSecurityConfig 进行 JWT 验证。请检查此链接 - https://github.com/manishsingh27/TokenBasedAuth/tree/main/stdedu/src/main/java/com/adms/stdedu/config

import org.springframework.context.annotation.Configuration;
import org.springframework.core.annotation.Order;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.oauth2.config.annotation.web.configuration.EnableResourceServer;
import org.springframework.security.oauth2.config.annotation.web.configuration.ResourceServerConfigurerAdapter;

@Configuration
//@Order(-21)
@EnableResourceServer
public class ResourceServiceConfiguration extends ResourceServerConfigurerAdapter {

    @Override
    public void configure(HttpSecurity http) throws Exception {
        http.csrf().disable().authorizeRequests().antMatchers("/**").hasAnyAuthority ("READ_PRIVILEGE","WRITE_PRIVILEGE");
    }

}
