在Spring Security的SecurityContext中存储自定义信息可以通过以下步骤实现:
下面是一个示例代码:
public class CustomUser {
private String username;
private String email;
// 省略getter和setter方法
}
public class CustomAuthentication implements Authentication {
private CustomUser customUser;
private boolean authenticated;
// 构造方法和其他方法省略
@Override
public Collection<? extends GrantedAuthority> getAuthorities() {
return null;
}
@Override
public Object getCredentials() {
return null;
}
@Override
public Object getDetails() {
return null;
}
@Override
public Object getPrincipal() {
return null;
}
@Override
public boolean isAuthenticated() {
return authenticated;
}
@Override
public void setAuthenticated(boolean isAuthenticated) throws IllegalArgumentException {
this.authenticated = isAuthenticated;
}
@Override
public String getName() {
return customUser.getUsername();
}
}
public class CustomAuthenticationProvider implements AuthenticationProvider {
@Override
public Authentication authenticate(Authentication authentication) throws AuthenticationException {
// 获取用户输入的用户名和密码
String username = authentication.getName();
String password = authentication.getCredentials().toString();
// 根据用户名和密码进行认证,这里省略具体的认证逻辑
// 认证成功后,创建一个包含自定义信息的CustomUser对象
CustomUser customUser = new CustomUser();
customUser.setUsername(username);
customUser.setEmail("example@example.com");
// 创建一个CustomAuthentication对象,并设置为已认证
CustomAuthentication customAuthentication = new CustomAuthentication();
customAuthentication.setAuthenticated(true);
customAuthentication.setCustomUser(customUser);
return customAuthentication;
}
@Override
public boolean supports(Class<?> authentication) {
return authentication.equals(UsernamePasswordAuthenticationToken.class);
}
}
@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {
@Autowired
private CustomAuthenticationProvider customAuthenticationProvider;
@Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception {
auth.authenticationProvider(customAuthenticationProvider);
}
@Override
protected void configure(HttpSecurity http) throws Exception {
// 配置其他的安全规则
}
@Bean
public SecurityContextRepository securityContextRepository() {
HttpSessionSecurityContextRepository repository = new HttpSessionSecurityContextRepository();
repository.setAllowSessionCreation(false);
return repository;
}
@Override
public void configure(WebSecurity web) throws Exception {
web.securityContextRepository(securityContextRepository());
}
}
通过以上步骤,就可以在Spring Security的SecurityContext中存储自定义信息了。在认证成功后,可以通过以下代码获取自定义信息:
CustomAuthentication authentication = (CustomAuthentication) SecurityContextHolder.getContext().getAuthentication();
CustomUser customUser = authentication.getCustomUser();
String username = customUser.getUsername();
String email = customUser.getEmail();
这样就可以获取到存储在SecurityContext中的自定义信息了。
