我有一个带有 jwt 身份验证的 Spring Boot Rest API。问题是我无法摆脱默认的 403 Access Denied 休息响应,如下所示:
{
"timestamp": 1516206966541,
"status": 403,
"error": "Forbidden",
"message": "Access Denied",
"path": "/api/items/2"
}
我创建了自定义 AccessDeniedHandler:
public class CustomAccessDeniedHandler implements AccessDeniedHandler {
@Override
public void handle(HttpServletRequest req,
HttpServletResponse res,
AccessDeniedException accessDeniedException) throws IOException, ServletException {
ObjectMapper mapper = new ObjectMapper();
res.setContentType("application/json;charset=UTF-8");
res.setStatus(403);
res.getWriter().write(mapper.writeValueAsString(new JsonResponse()
.add("timestamp", System.currentTimeMillis())
.add("status", 403)
.add("message", "Access denied")));
}
}
并将其添加到 WebConfig 类中
@EnableWebSecurity
public class WebSecurity extends WebSecurityConfigurerAdapter {
private UserDetailsService userDetailsService;
private BCryptPasswordEncoder bCryptPasswordEncoder;
@Autowired
public WebSecurity(UserDetailsService userDetailsService, BCryptPasswordEncoder bCryptPasswordEncoder) {
this.userDetailsService = userDetailsService;
this.bCryptPasswordEncoder = bCryptPasswordEncoder;
}
@Override
protected void configure(HttpSecurity http) throws Exception {
http
.sessionManagement()
.sessionCreationPolicy(SessionCreationPolicy.NEVER)
.and()
.csrf().disable()
.authorizeRequests()
.antMatchers(HttpMethod.POST, REGISTER_URL).permitAll()
.anyRequest().authenticated()
.and()
.exceptionHandling().accessDeniedHandler(accessDeniedHandler())
.and()
.addFilter(new JWTAuthenticationFilter(authenticationManager(), tokenProvider()))
.addFilter(new JWTAuthorizationFilter(authenticationManager(), tokenProvider()));
}
@Override
public void configure(AuthenticationManagerBuilder auth) throws Exception {
auth.userDetailsService(userDetailsService).passwordEncoder(bCryptPasswordEncoder);
}
@Bean
public TokenProvider tokenProvider(){
return new TokenProvider();
}
@Bean
public AccessDeniedHandler accessDeniedHandler(){
return new CustomAccessDeniedHandler();
}
}
尽管如此,我仍然收到默认的“拒绝访问”响应。调试时,我意识到自定义处理程序中的
handle
方法甚至没有被调用。这是什么情况?
我想我解决了问题。我必须创建一个自定义
AccessDeniedHandler
并将其设置为异常处理,而不是创建 AuthenticationEntryPoint
的实现。
WebConfig
现在看起来像这样:
@EnableWebSecurity
public class WebSecurity extends WebSecurityConfigurerAdapter {
private UserDetailsService userDetailsService;
private BCryptPasswordEncoder bCryptPasswordEncoder;
@Autowired
public WebSecurity(UserDetailsService userDetailsService, BCryptPasswordEncoder bCryptPasswordEncoder) {
this.userDetailsService = userDetailsService;
this.bCryptPasswordEncoder = bCryptPasswordEncoder;
}
@Override
protected void configure(HttpSecurity http) throws Exception {
http
.sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS)
.and()
.csrf().disable()
.authorizeRequests()
.antMatchers(HttpMethod.POST, REGISTER_URL).permitAll()
.anyRequest().authenticated()
.and()
.exceptionHandling().authenticationEntryPoint(authenticationEntryPoint())
.and()
.addFilter(new JWTAuthenticationFilter(authenticationManager(), tokenProvider()))
.addFilter(new JWTAuthorizationFilter(authenticationManager(), tokenProvider()));
}
@Override
public void configure(AuthenticationManagerBuilder auth) throws Exception {
auth.userDetailsService(userDetailsService).passwordEncoder(bCryptPasswordEncoder);
}
@Bean
public TokenProvider tokenProvider(){
return new TokenProvider();
}
@Bean
public AuthenticationEntryPoint authenticationEntryPoint(){
return new CustomAuthenticationEntryPoint();
}
}
和
CustomAuthenticationEntryPoint
:
public class CustomAuthenticationEntryPoint implements AuthenticationEntryPoint {
@Override
public void commence(HttpServletRequest req, HttpServletResponse res, AuthenticationException authException) throws IOException, ServletException {
res.setContentType("application/json;charset=UTF-8");
res.setStatus(403);
res.getWriter().write(JsonBuilder //my util class for creating json strings
.put("timestamp", DateGenerator.getDate())
.put("status", 403)
.put("message", "Access denied")
.build());
}
}
现在一切都如我所愿。
我有同样的问题并尝试按照正确答案解决,但它不能解决问题。 处理此问题的最佳方法是实现自定义访问拒绝处理程序。 AuthenticationEntryPoint 实现最适合处理 401、UNAUTHORIZED 访问,而 AccessDeniedHandler 实现最适合处理 403、FORBIDDEN 访问。
在实现类中重写 AccessDeniedHandler 的方法:
@Override
public void handle(HttpServletRequest request, HttpServletResponse response,
AccessDeniedException accessDeniedException) throws IOException, ServletException {
response.getWriter().write("Access Denied... Forbidden");
}
并在您的安全配置中添加此自定义访问拒绝处理程序,如下所示:
.exceptionHandling()
.authenticationEntryPoint(authenticationEntryPoint())
.accessDeniedHandler(accessDeniedHandler())
试试这个
@Override
protected void configure(HttpSecurity http) throws Exception {
http
.sessionManagement()
.sessionCreationPolicy(SessionCreationPolicy.NEVER)
.and()
.csrf().disable()
.authorizeRequests()
.antMatchers(HttpMethod.POST, REGISTER_URL).permitAll()
.anyRequest().authenticated()
.and().exceptionHandling().accessDeniedPage("/view/notAuth")
.and()
.addFilter(new JWTAuthenticationFilter(authenticationManager(), tokenProvider()))
.addFilter(new JWTAuthorizationFilter(authenticationManager(), tokenProvider()));
}
@Override
public void configure(AuthenticationManagerBuilder auth) throws Exception {
auth.userDetailsService(userDetailsService).passwordEncoder(bCryptPasswordEncoder);
}
@Bean
public TokenProvider tokenProvider(){
return new TokenProvider();
}
并为视图页面制作这个配置类
import java.util.List;
import org.springframework.context.annotation.Configuration;
import org.springframework.format.FormatterRegistry;
import org.springframework.http.converter.HttpMessageConverter;
import org.springframework.validation.MessageCodesResolver;

import org.springframework.web.method.support.HandlerMethodArgumentResolver;
import org.springframework.web.method.support.HandlerMethodReturnValueHandler;
import org.springframework.web.servlet.HandlerExceptionResolver;
import org.springframework.web.servlet.config.annotation.AsyncSupportConfigurer;
import org.springframework.web.servlet.config.annotation.ContentNegotiationConfigurer;
import org.springframework.web.servlet.config.annotation.CorsRegistry;
@Configuration
public class ViewRegistryConfig implements WebMvcConfigurer {
@Override
public void addViewControllers(ViewControllerRegistry registry) {
registry.addViewController("/view/notAuth").setViewName("notAuth");
}
@Override

// TODO Auto-generated method stub
}

@Override

@Override

@Override

// TODO Auto-generated method stub
return null;
}
@Override
public MessageCodesResolver getMessageCodesResolver() {
// TODO Auto-generated method stub
return null;
}
}
为 AccessDeniedException 添加 ExceptionHandler 在我的例子中起到了作用。
@ExceptionHandler (value = {AccessDeniedException.class})
public void handleAccessDeniedException(HttpServletRequest request, HttpServletResponse response,
AccessDeniedException accessDeniedException) throws IOException {
// 403
response.sendError(403, "Authorization Failed : " + accessDeniedException.getMessage());
}
这是一个最小的安全配置,演示了在访问被拒绝 (403) 场景时调用自定义
AccessDeniedHandler
:
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {
@Override
protected void configure(HttpSecurity http) throws Exception {
http
.authorizeRequests()
.antMatchers("/css/**", "/index").permitAll()
.antMatchers("/admin/**").hasRole("ADMIN")
.antMatchers("/user/**").hasRole("USER")
.and()
.formLogin()
.and()
.exceptionHandling()
.accessDeniedHandler((request, response, accessDeniedException) -> {
AccessDeniedHandler defaultAccessDeniedHandler = new AccessDeniedHandlerImpl();
defaultAccessDeniedHandler.handle(request, response, accessDeniedException);
});
}
@Autowired
public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
auth
.inMemoryAuthentication()
.withUser(User.withDefaultPasswordEncoder().username("user").password("password").roles("USER"))
.withUser(User.withDefaultPasswordEncoder().username("admin").password("password").roles("ADMIN"));
}
}
重现步骤:
user/password
http://localhost:8080/user/index
- 已授予访问权限http://localhost:8080/admin/index
- 访问被拒绝并且自定义 AccessDeniedHandler
被调用 据此:
http://www.baeldung.com/spring-security-custom-access-denied-page
您还需要添加:
.exceptionHandling().accessDeniedHandler(accessDeniedHandler());
猜测是在“配置”中。
