ruoyi若依框架SpringSecurity实现分析
若依是基于SpringBoot的快速开发平台,其安全框架是基于Spring Security的,以下是Spring Security在若依中的核心配置和类的简要说明:
SecurityConfig
:继承自WebSecurityConfigurerAdapter
,用于配置Spring Security的基础设置和权限规则。
@Configuration
public class SecurityConfig extends WebSecurityConfigurerAdapter {
@Autowired
private TokenAuthConfiguration tokenAuthConfiguration;
@Override
protected void configure(HttpSecurity httpSecurity) throws Exception {
httpSecurity
// 配置不需要认证的路径
.authorizeRequests()
.antMatchers("/login").permitAll()
// 其他所有路径需要认证
.anyRequest().authenticated()
.and()
// 配置登录和登出
.apply(tokenAuthConfiguration)
.and()
.csrf().disable(); // 关闭CSRF保护
}
}
TokenAuthConfiguration
:实现了AbstractHttpConfigurer
,用于配置基于Token的认证机制。
public class TokenAuthConfiguration extends AbstractHttpConfigurer {
@Override
public void configure(HttpSecurity http) throws Exception {
http
.addFilterBefore(authenticationTokenFilter, UsernamePasswordAuthenticationFilter.class);
}
// 省略其他配置细节
}
AuthenticationTokenFilter
:继承自GenericFilterBean
,用于从请求中提取Token,并进行身份验证。
public class AuthenticationTokenFilter extends OncePerRequestFilter {
@Autowired
private TokenManager tokenManager;
@Override
protected void doFilterInternal(HttpServletRequest request, HttpServletResponse response, FilterChain chain)
throws IOException, ServletException {
Authentication authentication = tokenManager.getAuthentication(request);
SecurityContextHolder.getContext().setAuthentication(authentication);
chain.doFilter(request, response);
}
}
TokenManager
:用于生成和验证Token。
@Component
public class TokenManager {
public Authentication getAuthentication(HttpServletRequest request) {
// 从HTTP头信息中获取Token
String token = request.getHeader(header);
if (token != null) {
// 解析Token并构建Authentication
// ...
}
return null;
}
}
以上代码提供了Spring Security在若依中使用Token认证的基本框架,具体的Token生成和验证逻辑需要根据项目需求实现。
