記住我功能 · Java后端框架Ⅲ

**1. `application.yml`配置數據庫信息** ```yml spring: datasource: username: root password: uhg</flEt3dff url: jdbc:mysql://localhost:3306/learndb?useUnicode=true&characterEncoding=UTF-8&serverTimezone=Asia/Shanghai driver-class-name: com.mysql.cj.jdbc.Driver ``` **2. 配置數據源** ```java @Configuration public class BrowserSecurityConfig { @Autowired private DataSource dataSource; @Bean public PersistentTokenRepository persistentTokenRepository() { JdbcTokenRepositoryImpl jdbcTokenRepository = new JdbcTokenRepositoryImpl(); jdbcTokenRepository.setDataSource(dataSource); //首次啟動時Spring Security需要自動建persistent_logins表，請將設置為true，建表后將其設置為false jdbcTokenRepository.setCreateTableOnStartup(false); return jdbcTokenRepository; } } ``` **3. 開啟記住我功能** ```java @Configuration @RequiredArgsConstructor public class SecurityConfig extends WebSecurityConfigurerAdapter { final LoginServiceImpl loginService; final PersistentTokenRepository tokenRepository; @Override protected void configure(HttpSecurity http) throws Exception { //開啟記住我功能 http.rememberMe() //有效期，如果不設置默認為2周，單位為s .tokenValiditySeconds(3600) .tokenRepository(tokenRepository) .userDetailsService(loginService); } } ``` **4. 登錄表單** ```html <form action="/login" method="post"> 用戶名:<input type="text" name="username"/><br/> 密碼：<input type="password" name="password"/><br/>  記住我：<input type="checkbox"name="remember-me"title="記住密碼"/><br/> <input type="submit" value="提交"/> </form> ``` **5. 測試** 經測試，一個賬號登錄后，關閉瀏覽器再打開瀏覽器訪問不再需要登錄，配置成功了。
