java - Spring security - 错误导致性能问题

问题描述

我遇到了 SpringBoot 应用程序的问题。我的 ICS 报告了这个 API的高响应时间，但我的代码指标表明一切都很好，例如，发送到我的 API 的查询只需要 50 毫秒来运行“业务”代码，但有效响应需要超过 500 毫秒！

我的 JVM 的内部日志说，在每个请求上，我都有一个“ UsernameNotFoundExcption ”，即使凭据是正确的并且 API 工作正常。这就是为什么我认为我的问题来自 SpringSecurity 层但我无法确定原因。

我的切入点：

@Component
public class BasicAuthenticationPoint extends BasicAuthenticationEntryPoint {
    @Override
    public void commence(HttpServletRequest request, HttpServletResponse response, AuthenticationException authEx)
            throws IOException, ServletException {
        response.addHeader("WWW-Authenticate", "Basic realm=" + getRealmName());
        response.setStatus(HttpServletResponse.SC_UNAUTHORIZED);
        response.setCharacterEncoding("utf-8");
        PrintWriter writer = response.getWriter();
        writer.println("HTTP Status 401 - " + authEx.getMessage());
    }

    @Override
    public void afterPropertiesSet() throws Exception {
        setRealmName("MYAPI");
        super.afterPropertiesSet();
    }
}

还有我的适配器：

@Configuration
@EnableWebSecurity
public class SpringSecurityConfig extends WebSecurityConfigurerAdapter {

    @Autowired
    private BasicAuthenticationPoint basicAuthenticationPoint;

    @Bean
    public BCryptPasswordEncoder encoder() {
        return new BCryptPasswordEncoder();
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        HttpSecurity httpSec = http.csrf().disable();
        httpSec = httpSec.authorizeRequests()
                .antMatchers("/my-business-resources/**").hasRole("USER")
                .antMatchers("/actuator/**").hasRole("ADMIN")
                .and();
        httpSec.httpBasic().authenticationEntryPoint(basicAuthenticationPoint).and()
        .sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS);
    }

    @Autowired
    public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
        // Load users file
        Resource confFile = resourceLoader.getResource("classpath:users.list");

        // Returns users from the configuration file <username, password (BCrypted), admin (boolean)>
        List<ApiUser> users = ApiUtils.getUsersFromFile(confFile);

        for(ApiUser u : users){
            // Add the username/password to the in-memory authentication manager
            if (u.admin)
                auth.inMemoryAuthentication().withUser(u.username).password(u.password).roles("USER", "ADMIN");
            else
                auth.inMemoryAuthentication().withUser(u.username).password(u.password).roles("USER");

        }
    }
}

我错过了什么 ？

PS：我的 Spring Boot 应用程序被打包为 WAR 并在 Tomcat 服务器内执行以实现标准化目的。

解决方案

好的，经过大量调试，我发现了问题！

问题出在我用来填充内存身份验证器的代码中：

for(ApiUser u : users){
    // Add the username/password to the in-memory authentication manager
    if (u.admin)
        auth.inMemoryAuthentication().withUser(u.username).password(u.password).roles("USER", "ADMIN");
    else
        auth.inMemoryAuthentication().withUser(u.username).password(u.password).roles("USER");
}

auth.inMemoryAuthentication()多次调用的事实InMemoryUserDetailsManagerConfigurer<AuthenticationManagerBuilder>每次都会创建一个新的（Spring 代码），因此我们有与用户一样多的不同AuthenticationManager用户（每个用户一个用户），因此对每个请求执行多次身份验证过程。

这是我修复错误的方法：

@Autowired
public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
    // Load users file
    Resource confFile = resourceLoader.getResource("classpath:users.list");

    // Returns users from the configuration file <username, password (BCrypted), admin (boolean)>
    List<ApiUser> users = ApiUtils.getUsersFromFile(confFile);

    @SuppressWarnings("rawtypes")
    UserDetailsBuilder udb = null;

    for(ApiUser u : users){
        // Add the username/password to the in-memory authentication manager
        if (udb == null)
            udb = auth.inMemoryAuthentication().withUser(u.username).password(u.password);
        else
            udb = udb.and().withUser(u.username).password(u.password);

        if (u.admin)
            udb.roles("USER", "ADMIN");
        else
            udb.roles("USER");
    }
}

现在我的平均响应时间是 80 毫秒
