可以使用 jjwt 库来实现基于 JSON Web Token 的认证,具体实现可以参考以下代码:
@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {
@Autowired
private UserDetailsService userDetailsService;
@Autowired
private JwtAuthenticationEntryPoint unauthorizedHandler;
@Bean
public JwtAuthenticationFilter authenticationTokenFilterBean() throws Exception {
return new JwtAuthenticationFilter();
}
@Override
public void configure(AuthenticationManagerBuilder authenticationManagerBuilder) throws Exception {
authenticationManagerBuilder
.userDetailsService(userDetailsService)
.passwordEncoder(passwordEncoder());
}
@Bean(BeanIds.AUTHENTICATION_MANAGER)
@Override
public AuthenticationManager authenticationManagerBean() throws Exception {
return super.authenticationManagerBean();
}
@Bean
public PasswordEncoder passwordEncoder() {
return new BCryptPasswordEncoder();
}
@Override
protected void configure(HttpSecurity http) throws Exception {
http
.cors()
.and()
.csrf()
.disable()
.exceptionHandling()
.authenticationEntryPoint(unauthorizedHandler)
.and()
.sessionManagement()
.sessionCreationPolicy(SessionCreationPolicy.STATELESS)
.and()
.authorizeRequests()
.antMatchers("/api/auth/**")
.permitAll()
.anyRequest()
.authenticated();
// Add our custom JWT security filter
http.addFilterBefore(authenticationTokenFilterBean(), UsernamePasswordAuthenticationFilter.class);
}
}
其中,JwtAuthenticationFilter 是一个自定义的过滤器,用于解析和验证 JWT,具体实现可以参考以下代码:
public class JwtAuthenticationFilter extends OncePerRequestFilter {
@Autowired
private JwtTokenProvider tokenProvider;
@Autowired
private CustomUserDetailsService customUserDetailsService;
@Override
protected void doFilterInternal(HttpServletRequest request, HttpServletResponse response, FilterChain filterChain) throws ServletException, IOException {
try {
String jwt = getJwtFromRequest(request);
if (StringUtils.hasText(jwt) && tokenProvider.validateToken(jwt)) {
Long userId = tokenProvider.getUserIdFromJWT(jwt);
UserDetails userDetails = customUserDetailsService.loadUserById(userId);
UsernamePasswordAuthenticationToken authentication = new UsernamePasswordAuthenticationToken(userDetails, null, userDetails.getAuthorities());
authentication.setDetails(new WebAuthenticationDetailsSource().buildDetails(request));
SecurityContextHolder.getContext().setAuthentication(authentication);
}
} catch (Exception ex) {
logger.error("Could not set user authentication in security context", ex);
}
filterChain.doFilter(request, response);
}
private String getJwtFromRequest(HttpServletRequest request) {
String bearerToken = request.getHeader("Authorization");
if (StringUtils.hasText(bearerToken) && bearerToken.startsWith("Bearer ")) {
return bearerToken.substring(7, bearerToken.length());
}
return null;
}
}
以上代码实现了基于 JWT 的认证,具体使用可以参考 Spring Boot 官方文档。
