五分钟带你玩转SpringSecurity（七）带你优雅的实现记住我功能

@EnableWebSecurity
public class SpringSecurityConfig extends WebSecurityConfigurerAdapter {
    @Autowired
    DataSource dataSource;
    /**
     * 记住我功能
     * 
     * @return
     */
    @Bean
    public JdbcTokenRepositoryImpl jdbcTokenRepository() {
        JdbcTokenRepositoryImpl jdbcTokenRepository = new JdbcTokenRepositoryImpl();
        jdbcTokenRepository.setDataSource(dataSource);
        return jdbcTokenRepository;
    }
    @Override
    protected void configure(HttpSecurity http) throws Exception {
        // 验证码过滤器
        http.addFilterBefore(imageCodeValidateFilter, UsernamePasswordAuthenticationFilter.class)
            // 跳转前台的地址
            .formLogin().loginPage("/loginPage")
            // 登录调用的接口地址
            .loginProcessingUrl("/login").successHandler(customAuthenticationSuccessHandler)
            // 无权限允许访问
            .and().authorizeRequests()
            .antMatchers("/login", "/loginPage", "/code/image", "/logout/expirePage", "/logout/page",
                "/oauth/logoutSession", "/oauth/customLogout")
            .permitAll().anyRequest().authenticated()
             // 记住功能配置
            .and().rememberMe() 
            .tokenRepository(jdbcTokenRepository()) // 保存登录信息
            .tokenValiditySeconds(60 * 30 * 30); // 记住我有效时长
    }
}
