成功登录后,Spring Boot重定向到当前页面

Question

我在模态窗口中有登录表单.登录成功后,用户将被重定向到/页面.我正在尝试找到一种方法,以便在登录后留在联系页面或其他页面上.这该怎么做？我的代码是:

@Override
protected void configure(HttpSecurity http) throws Exception {
    http
        .authorizeRequests()
            .antMatchers("/css/**","/js/**","/fonts/**","/images/**","/home","/","/kontakt").permitAll()
            .antMatchers("/userlist").hasRole("ADMIN")
            .anyRequest().authenticated();
    http
        .formLogin()
            .loginPage("/login")
            .permitAll()
            .and()
        .logout()
            .logoutRequestMatcher(new AntPathRequestMatcher("/logout"))
            .logoutSuccessUrl("/");
}

Answer 1

您可以使用自定义AuthenticationSuccessHandler并设置useReferer为true.

@Bean
public AuthenticationSuccessHandler successHandler() {
    SimpleUrlAuthenticationSuccessHandler handler = new SimpleUrlAuthenticationSuccessHandler();
    handler.setUseReferer(true);
    return handler;
}

在你的configure方法中:

http
    .formLogin()
        .loginPage("/login")
        .successHandler(successHandler())
        .permitAll()
        .and()

Answer 2

只是为了提供替代解决方案:

formLogin()
    .loginPage("/login")
    .defaultSuccessUrl("/")

defaultSuccessUrl是添加自定义的快捷方式SuccessHandler.

Answer 3

我有一个奇怪的问题会导致登录时将用户重定向到 localhost:8080/js/bootstrap.min.js

如果其他人在登录时遇到奇怪的重定向，这似乎覆盖了.defaultSuccessUrl()，然后尝试在下面添加此代码SecurityConfig：

@Override
public void configure(WebSecurity security){
    security.ignoring().antMatchers("/css/**","/images/**","/js/**");
}

将所有Resources/static文件夹添加到antMatchers()

Answer 4

你也可以在你的AuthenticationSuccessHandler实现中做到这一点：

@Override
public void onAuthenticationSuccess(HttpServletRequest request, 
HttpServletResponse response, Authentication authentication) throws 
IOException, ServletException 
{
    //Do your logic;
    response.sendRedirect(request.getHeader("referer");
}
