认证成功处理器、认证失败处理器、注销成功处理器

认证成功处理器

实际上在UsernamePasswordAuthenticationFilter进行登录认证的时候，如果登录成功了是会调用AuthenticationSuccessHandler的方法进行认证成功后的处理的。AuthenticationSuccessHandler就是登录成功处理器。

我们也可以自己去自定义成功处理器进行成功后的相应处理。

在handler包下创建SGSuccessHandler类

@Component
public class SGSuccessHandler implements AuthenticationSuccessHandler {

    @Override
    public void onAuthenticationSuccess(HttpServletRequest request, HttpServletResponse response, Authentication authentication) throws IOException, ServletException {
        System.out.println("认证成功了");
    }
}

SecurityConfig配置类

@Configuration
public class SecurityConfig extends WebSecurityConfigurerAdapter {

    @Autowired
    private AuthenticationSuccessHandler successHandler;

    @Autowired
    private AuthenticationFailureHandler failureHandler;

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.formLogin().successHandler(successHandler);

        http.authorizeRequests().anyRequest().authenticated();
    }
}

认证失败处理器

实际上在UsernamePasswordAuthenticationFilter进行登录认证的时候，如果认证失败了是会调用AuthenticationFailureHandler的方法进行认证失败后的处理的。AuthenticationFailureHandler就是登录失败处理器。

我们也可以自己去自定义失败处理器进行失败后的相应处理。

在handler包下创建SGFailureHandler类

@Component
public class SGFailureHandler implements AuthenticationFailureHandler {

    @Override
    public void onAuthenticationFailure(HttpServletRequest request, HttpServletResponse response, AuthenticationException exception) throws IOException, ServletException {
        System.out.println("认证失败了");
    }
}

SecurityConfig配置类

@Configuration
public class SecurityConfig extends WebSecurityConfigurerAdapter {

    @Autowired
    private AuthenticationSuccessHandler successHandler;

    @Autowired
    private AuthenticationFailureHandler failureHandler;

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.formLogin()
                // 配置认证成功处理器
                .successHandler(successHandler)
                // 配置认证失败处理器
                .failureHandler(failureHandler);

        http.authorizeRequests().anyRequest().authenticated();
    }
}

注销成功处理器

在handler包下创建SGLogoutSuccessHandler类

@Component
public class SGLogoutSuccessHandler implements LogoutSuccessHandler {
    @Override
    public void onLogoutSuccess(HttpServletRequest request, HttpServletResponse response, Authentication authentication) throws IOException, ServletException {
        System.out.println("注销成功");
    }
}

SecurityConfig配置类

@Configuration
public class SecurityConfig extends WebSecurityConfigurerAdapter {

    @Autowired
    private AuthenticationSuccessHandler successHandler;

    @Autowired
    private AuthenticationFailureHandler failureHandler;

    @Autowired
    private LogoutSuccessHandler logoutSuccessHandler;

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.formLogin()
                // 配置认证成功处理器
                .successHandler(successHandler)
                // 配置认证失败处理器
                .failureHandler(failureHandler);

        http.logout()
                // 配置注销成功处理器
                .logoutSuccessHandler(logoutSuccessHandler);

        http.authorizeRequests().anyRequest().authenticated();
    }
}
