Question

我正在尝试使用JWT令牌在我的REST API中使用Spring Security，但每次我尝试使用端点进行登录时：/我的Api登录，我得到403禁止，我不明白为什么，一个完全空洞的身体信息。

这是我的WebSecurity extenson配置：

package com.debtServer.authentication;

import org.springframework.http.HttpMethod;
import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.config.http.SessionCreationPolicy;
import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
import org.springframework.web.cors.CorsConfiguration;
import org.springframework.web.cors.CorsConfigurationSource;
import org.springframework.web.cors.UrlBasedCorsConfigurationSource;
import org.springframework.context.annotation.Bean;

@EnableWebSecurity
public class WebSecurity extends WebSecurityConfigurerAdapter {

    private UserDetailsService userDetailsService;
    private BCryptPasswordEncoder bCryptPasswordEncoder;

    public WebSecurity(UserDetailsServiceImpl userDetailsService, BCryptPasswordEncoder bCryptPasswordEncoder) {
        this.userDetailsService = userDetailsService;
        this.bCryptPasswordEncoder = bCryptPasswordEncoder;
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.cors().and().csrf().disable().authorizeRequests()
                .antMatchers(HttpMethod.POST, SecurityConstants.SIGN_UP_URL).permitAll()
                .anyRequest().authenticated()
                .and()
                .addFilter(new JWTAuthenticationFilter(authenticationManager()))
                .addFilter(new JWTAuthorizationFilter(authenticationManager()))
                // this disables session creation on Spring Security
                .sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS);
    }

    @Override
    public void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.userDetailsService(userDetailsService).passwordEncoder(bCryptPasswordEncoder);
    }

    @Bean
    CorsConfigurationSource corsConfigurationSource() {
        final UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
        source.registerCorsConfiguration("/**", new CorsConfiguration().applyPermitDefaultValues());
        return source;
    }
}

以下两个类是配置的两个过滤器：

package com.debtServer.authentication;

import io.jsonwebtoken.Jwts;
import org.springframework.security.authentication.AuthenticationManager;
import org.springframework.security.authentication.UsernamePasswordAuthenticationToken;
import org.springframework.security.core.context.SecurityContextHolder;
import org.springframework.security.web.authentication.www.BasicAuthenticationFilter;

import javax.servlet.FilterChain;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
import java.util.ArrayList;

public class JWTAuthorizationFilter extends BasicAuthenticationFilter {

    public JWTAuthorizationFilter(AuthenticationManager authManager) {
        super(authManager);
    }

    @Override
    protected void doFilterInternal(HttpServletRequest req,
                                    HttpServletResponse res,
                                    FilterChain chain) throws IOException, ServletException {
        String header = req.getHeader(SecurityConstants.HEADER_STRING);
        if (header == null || !header.startsWith(SecurityConstants.TOKEN_PREFIX)) {
            chain.doFilter(req, res);
            return;
        }
        UsernamePasswordAuthenticationToken authentication = getAuthentication(req);

        SecurityContextHolder.getContext().setAuthentication(authentication);
        chain.doFilter(req, res);
    }

    private UsernamePasswordAuthenticationToken getAuthentication(HttpServletRequest request) {
        String token = request.getHeader(SecurityConstants.HEADER_STRING);
        if (token != null) {
            // parse the token.
            String user = Jwts.parser()
                    .setSigningKey(SecurityConstants.SECRET.getBytes())
                    .parseClaimsJws(token.replace(SecurityConstants.TOKEN_PREFIX, ""))
                    .getBody()
                    .getSubject();

            if (user != null) {
                return new UsernamePasswordAuthenticationToken(user, null, new ArrayList<>());
            }
            return null;
        }
        return null;
    }
}

第二次过滤：

package com.debtServer.authentication;

import com.debtServer.model.LoginBindingModel;
import com.fasterxml.jackson.databind.ObjectMapper;
import io.jsonwebtoken.Jwts;
import io.jsonwebtoken.SignatureAlgorithm;
import org.springframework.security.authentication.AuthenticationManager;
import org.springframework.security.authentication.UsernamePasswordAuthenticationToken;
import org.springframework.security.core.Authentication;
import org.springframework.security.core.AuthenticationException;
import org.springframework.security.core.userdetails.User;
import org.springframework.security.web.authentication.UsernamePasswordAuthenticationFilter;

import javax.servlet.FilterChain;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
import java.util.ArrayList;
import java.util.Date;

import static com.debtServer.authentication.SecurityConstants.*;
import com.debtServer.persistence.entity.*;
public class JWTAuthenticationFilter extends UsernamePasswordAuthenticationFilter {
    private AuthenticationManager authenticationManager;

    public JWTAuthenticationFilter(AuthenticationManager authenticationManager) {
        this.authenticationManager = authenticationManager;
    }

    @Override
    public Authentication attemptAuthentication(HttpServletRequest req,
                                                HttpServletResponse res) throws AuthenticationException {
        try {
            LoginBindingModel loginCredentials = new ObjectMapper()
                    .readValue(req.getInputStream(), LoginBindingModel.class);

             return authenticationManager.authenticate(
                    new UsernamePasswordAuthenticationToken(
                            loginCredentials.getUsername(),
                            loginCredentials.getPassword(),
                            new ArrayList<>())
            );
        } catch (IOException e) {
            throw new RuntimeException(e);
        }
    }

    @Override
    protected void successfulAuthentication(HttpServletRequest req,
                                            HttpServletResponse res,
                                            FilterChain chain,
                                            Authentication auth) throws IOException, ServletException {
        String token = Jwts.builder()
                .setSubject(((User) auth.getPrincipal()).getUsername())
                .setExpiration(new Date(System.currentTimeMillis() + EXPIRATION_TIME))
                .signWith(SignatureAlgorithm.HS512, SECRET.getBytes())
                .compact();
        res.addHeader(HEADER_STRING, TOKEN_PREFIX + token);
    }
}

最后我执行了用户详细信息：

package com.debtServer.authentication;

import org.springframework.security.core.userdetails.User;
import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.security.core.userdetails.UsernameNotFoundException;
import org.springframework.stereotype.Service;
import com.debtServer.persistence.repository.UserRepository;
import com.debtServer.persistence.entity.*;

import java.util.List;

import static java.util.Collections.emptyList;

@Service
public class UserDetailsServiceImpl implements UserDetailsService {
    private UserRepository applicationUserRepository;

    public UserDetailsServiceImpl(UserRepository applicationUserRepository) {
        this.applicationUserRepository = applicationUserRepository;
    }

    @Override
    public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
        UserEntity applicationUser = applicationUserRepository.findByNEmail(username);
        if (applicationUser == null) {
            throw new UsernameNotFoundException(username);
        }
        return new User(applicationUser.getUsername(), applicationUser.getPassword(), emptyList());
    }
}

我正在使用Spring Security。

更新：我在控制台中发现错误：

java.lang.ClassNotFoundException: javax.xml.bind.DatatypeConverter
    at java.base/jdk.internal.loader.BuiltinClassLoader.loadClass(BuiltinClassLoader.java:582) ~[na:na]
    at java.base/jdk.internal.loader.ClassLoaders$AppClassLoader.loadClass(ClassLoaders.java:185) ~[na:na]

    at com.debtServer.authentication.JWTAuthenticationFilter.successfulAuthentication(JWTAuthenticationFilter.java:58) ~[classes/:na]

第58行就是这一行：.compact();

Answer 1

我刚刚发现了问题。问题是我使用的是Java 9，它似乎与我使用的一些扩展不兼容。我改为8，现在好了。

Answer 2

在下面的pom.xml中添加依赖项以解决该问题。

<dependency>
    <groupId>javax.xml.bind</groupId>
     <artifactId>jaxb-api</artifactId>
    <version>2.3.0</version>
 </dependency>

Answer 3

也许你错过了csrf令牌。弹簧安全性默认csrf配置值已启用且没有csrf令牌弹簧安全性返回403状态。

这是什么是csrf以及如何添加csrf令牌。： https://docs.spring.io/spring-security/site/docs/current/reference/html/csrf.html#csrf-using

使用JWT返回403的Spring身份验证
