Question

我想替换默认的拒绝访问权限页面：

使用我的自定义页面，我的方法是：

@Configuration
@EnableWebSecurity
public class SecurityContextConfigurer extends WebSecurityConfigurerAdapter {

    @Autowired
private UserDetailsService userDetailsService;

@Override
public void configure(WebSecurity web) throws Exception {
    web.ignoring().antMatchers("/resources/**");
}

@Override
protected void configure(HttpSecurity http) throws Exception {

    http.sessionManagement().maximumSessions(1)
            .sessionRegistry(sessionRegistry()).expiredUrl("/");
    http.authorizeRequests().antMatchers("/").permitAll()
            .antMatchers("/register").permitAll()
            .antMatchers("/security/checkpoint/for/admin/**").hasRole("ADMIN")
            .antMatchers("/rest/users/**").hasRole("ADMIN").anyRequest()
            .authenticated().and().formLogin().loginPage("/")
            .defaultSuccessUrl("/welcome").permitAll().and().logout()
            .logoutUrl("/logout");
}

@Bean
public SessionRegistry sessionRegistry() {
    return new SessionRegistryImpl();
}

@Bean
public AuthenticationProvider daoAuthenticationProvider() {
    DaoAuthenticationProvider daoAuthenticationProvider = new DaoAuthenticationProvider();
    daoAuthenticationProvider.setUserDetailsService(userDetailsService);

    return daoAuthenticationProvider;

}

@Bean
public ProviderManager providerManager() {

    List<AuthenticationProvider> arg0 = new CopyOnWriteArrayList<AuthenticationProvider>();
    arg0.add(daoAuthenticationProvider());

    return  new ProviderManager(arg0);

}

@Bean(name = "myAuthenticationManagerBean")
@Override
public AuthenticationManager authenticationManagerBean() throws Exception {
    return super.authenticationManagerBean();
}

@Override
protected AuthenticationManager authenticationManager() throws Exception {
    return providerManager();
}

    @Bean
    public ExceptionTranslationFilter exceptionTranslationFilter() {
        ExceptionTranslationFilter exceptionTranslationFilter = 
                new ExceptionTranslationFilter(new CustomAuthenticationEntryPoint());
        exceptionTranslationFilter.setAccessDeniedHandler(accessDeniedHandler());

        return exceptionTranslationFilter;
    }
    @Bean
    public AccessDeniedHandlerImpl accessDeniedHandler() {
        AccessDeniedHandlerImpl accessDeniedHandlerImpl = new 
                AccessDeniedHandlerImpl();
        accessDeniedHandlerImpl.setErrorPage("/page_403.jsp");
        System.out.println("ACCESS DENIED IS CALLED......");
        return accessDeniedHandlerImpl;
    }

    private class CustomAuthenticationEntryPoint implements AuthenticationEntryPoint{

        @Override
        public void commence(HttpServletRequest request, HttpServletResponse response,
                AuthenticationException authenticationException) throws IOException,
                ServletException {

            response.sendError(HttpServletResponse.SC_FORBIDDEN,
                    "Access denied.");
        }

    }   

}

但是上面的这个配置我仍然没有完成工作并看到相同的

是否有更多的豆必须为此目的注入？

免责声明：这不仅是解决方案，还是一个有效的解决方案。

在这种情况下，我的方法将尽可能简单，即在SecurityContext中添加此方法

@Override
protected void configure(HttpSecurity http) throws Exception {

    http.sessionManagement().maximumSessions(1)
            .sessionRegistry(sessionRegistry()).expiredUrl("/");
    http.authorizeRequests().antMatchers("/").permitAll()
            .antMatchers("/register").permitAll()
            .antMatchers("/security/checkpoint/for/admin/**").hasRole("ADMIN")
            .antMatchers("/rest/users/**").hasRole("ADMIN").anyRequest()
            .authenticated().and().formLogin().loginPage("/")
            .defaultSuccessUrl("/welcome").permitAll().and().logout()
            .logoutUrl("/logout").and()
            .exceptionHandling().accessDeniedPage("/page_403");//this is what you have to do here to get job done.
}

作为@M。 Deinum指出，您应该告诉Spring Security如何合并这些bean。无论如何，对于你想要实现的目标，有一种更简单的方法：

@Configuration
@EnableWebSecurity
public class SecurityContextConfigurer extends WebSecurityConfigurerAdapter {
    // Rest omitted

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
                // The usual stuff
                .exceptionHandling()
                    .accessDeniedPage("/page_403.jsp")
                    .authenticationEntryPoint((request, response, authException) -> {
                        response.sendError(HttpServletResponse.SC_FORBIDDEN);
                    });
    }
}

自定义HTTP 403页面在Spring Security中不起作用
