我已经创建了用户和角色实体类，用于使用引导创建简单的注册页面，但每次我转到浏览器时，它都会重定向到spring security登录页面。我尝试了很多方法来防止这种情况发生，但都不管用。所以，请给我一个解决方案。

当使用spring boot并添加 spring-boot-starter-security 依赖于类路径，Spring Security 将在默认情况下自动保护所有端点，从而将您重定向到 /login 每当您尝试访问受保护的资源时，都会显示此页。
您可以删除 spring-boot-starter-security 如果您根本不需要安全性，或者您可以通过定义 SecurityFilterChain 比恩，就像这样：

@EnableWebSecurity
public class SecurityConfig {
    @Bean
    SecurityFilterChain securityFilterChain(HttpSecurity http) {
        http.authorizeRequests((requests) ->
            requests.anyRequest().permitAll();
        );

        return http.build();
    }
}

如果您需要任何其他类型的定制，SpringSecuritySamples项目可以是一个很好的切入点。
