在Spring Security中,可以通过配置账户锁定来增强安全性。当用户连续输入错误的密码时,可以将其账户锁定一段时间,以防止恶意攻击。具体实现方式如下:
1. 在数据库中添加一个字段用于记录账户是否被锁定。
2. 在Spring Security的配置文件中添加如下代码:
```
@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {
@Autowired
private UserDetailsService userDetailsService;
@Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception {
auth.userDetailsService(userDetailsService).passwordEncoder(passwordEncoder());
}
@Override
protected void configure(HttpSecurity http) throws Exception {
http.authorizeRequests()
.antMatchers("/admin/**").hasRole("ADMIN")
.antMatchers("/user/**").hasAnyRole("ADMIN", "USER")
.anyRequest().authenticated()
.and()
.formLogin()
.loginPage("/login")
.defaultSuccessUrl("/home")
.permitAll()
.and()
.logout()
.permitAll()
.and()
.rememberMe()
.key("uniqueAndSecret")
.tokenValiditySeconds(86400)
.and()
.exceptionHandling().accessDeniedPage("/403")
.and()
.csrf().disable();
}
@Bean
public PasswordEncoder passwordEncoder() {
return new BCryptPasswordEncoder();
}
}
```
3. 在UserDetailsService的实现类中添加如下代码:
```
@Service
public class UserDetailsServiceImpl implements UserDetailsService {
@Autowired
private UserRepository userRepository;
@Override
public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
User user = userRepository.findByUsername(username);
if (user == null) {
throw new UsernameNotFoundException("User not found");
}
if (user.isLocked()) {
throw new LockedException("User account is locked");
}
return new org.springframework.security.core.userdetails.User(user.getUsername(), user.getPassword(),
user.isEnabled(), true, true, !user.isLocked(),
AuthorityUtils.createAuthorityList(user.getRole()));
}
}
```
在上述代码中,如果用户被锁定,则会抛出LockedException异常,从而阻止用户登录。
