Spring Boot Security 设置超时时间
整件事情的流程
下面是实现 Spring Boot Security 设置超时时间的步骤：
| 步骤 | 动作 | 代码 |
|---|---|---|
| 1 | 创建一个新的 Spring Boot 项目 | 无 |
| 2 | 添加 Spring Security 依赖 | xml <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-security</artifactId> </dependency> |
| 3 | 创建一个自定义的 UserDetails 实现类 | 无 |
| 4 | 创建一个自定义的 UserDetailsService 实现类 | 无 |
| 5 | 创建一个自定义的 AuthenticationProvider 实现类 | 无 |
| 6 | 配置 Spring Security | java @Configuration @EnableWebSecurity public class SecurityConfig extends WebSecurityConfigurerAdapter { @Autowired private UserDetailsService userDetailsService; @Override protected void configure(AuthenticationManagerBuilder auth) throws Exception { auth.authenticationProvider(authenticationProvider()); } @Override protected void configure(HttpSecurity http) throws Exception { http .authorizeRequests() .anyRequest().authenticated() .and() .formLogin() .and() .logout() .permitAll(); } @Bean public AuthenticationProvider authenticationProvider() { DaoAuthenticationProvider authenticationProvider = new DaoAuthenticationProvider(); authenticationProvider.setUserDetailsService(userDetailsService); return authenticationProvider; } } |
| 7 | 配置超时时间 | java @Configuration @EnableWebSecurity public class SecurityConfig extends WebSecurityConfigurerAdapter { @Autowired private UserDetailsService userDetailsService; @Override protected void configure(AuthenticationManagerBuilder auth) throws Exception { auth.authenticationProvider(authenticationProvider()); } @Override protected void configure(HttpSecurity http) throws Exception { http .authorizeRequests() .anyRequest().authenticated() .and() .formLogin() .and() .logout() .permitAll() .and() .sessionManagement() .maximumSessions(1) .maxSessionsPreventsLogin(true); } @Bean public AuthenticationProvider authenticationProvider() { DaoAuthenticationProvider authenticationProvider = new DaoAuthenticationProvider(); authenticationProvider.setUserDetailsService(userDetailsService); return authenticationProvider; } } |
代码解释
1. 创建一个自定义的 UserDetails 实现类
public class CustomUserDetails implements UserDetails {
// 自定义 User 实体类，可以根据需求添加字段和方法
@Override
public Collection<? extends GrantedAuthority> getAuthorities() {
// 返回用户的权限列表，可以根据需求进行设置
return null;
}
// 其他 UserDetails 的方法
}
2. 创建一个自定义的 UserDetailsService 实现类
@Service
public class CustomUserDetailsService implements UserDetailsService {
@Override
public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
// 根据用户名从数据库或其他地方查询用户信息，并构建 CustomUserDetails 对象返回
return null;
}
}
3. 创建一个自定义的 AuthenticationProvider 实现类
@Component
public class CustomAuthenticationProvider implements AuthenticationProvider {
@Autowired
private UserDetailsService userDetailsService;
@Override
public Authentication authenticate(Authentication authentication) throws AuthenticationException {
// 根据 authentication 获取用户输入的用户名和密码，然后根据用户名查询用户信息
String username = authentication.getName();
String password = authentication.getCredentials().toString();
UserDetails userDetails = userDetailsService.loadUserByUsername(username);
// 自定义验证逻辑，比较密码是否匹配等
if (password.equals(userDetails.getPassword())) {
return new UsernamePasswordAuthenticationToken(username, password, userDetails.getAuthorities());
} else {
throw new BadCredentialsException("Invalid credentials");
}
}
@Override
public boolean supports(Class<?> authentication) {
return authentication.equals(UsernamePasswordAuthenticationToken.class);
}
}
4. 配置 Spring Security
@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {
@Autowired
private UserDetailsService userDetailsService;
@Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception {
auth.authenticationProvider(authenticationProvider());
}
@Override
protected void configure(HttpSecurity http) throws Exception {
http
.authorizeRequests()
.anyRequest().authenticated()
.and()
.formLogin()
.and()
.logout()
.permitAll();
}
@Bean
public AuthenticationProvider authenticationProvider() {
DaoAuthenticationProvider authenticationProvider = new DaoAuthenticationProvider();
authenticationProvider.setUserDetailsService(userDetailsService);
return authenticationProvider;
}
}
5. 配置超时时间
@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {
@Autowired
private UserDetailsService userDetailsService;
@Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception {
auth
