안녕하세요 user-service에서 WebSecurity를 작성하고 apigateway에 user-service 정보를 추가하고 - id: user-service uri: lb://USER-SERVICE predicates: - Path=/user-service/login - Method=POST filters: - RemoveRequestHeader=Cookie - RewritePath=/user-service/(?<segment>.*), /$\{segment}- id: user-service uri: lb://USER-SERVICE predicates: - Path=/user-service/users # 회원가입 - Method=POST filters: - RemoveRequestHeader=Cookie - RewritePath=/user-service/(?<segment>.*), /$\{segment}- id: user-service uri: lb://USER-SERVICE predicates: - Path=/user-service/** - Method=GET filters: - RemoveRequestHeader=Cookie - RewritePath=/user-service/(?<segment>.*), /$\{segment}   아래처럼 유레카 서버를 키고 user-service를 클릭했는데 forbbiden 403에러가 뜹니다..   다음은 WebSecurity 코드입니다. @Configuration@EnableWebSecuritypublic class WebSecurity extends WebSecurityConfigurerAdapter { private UserService userService; private BCryptPasswordEncoder bCryptPasswordEncoder; private Environment env; public WebSecurity(Environment env, UserService userService, BCryptPasswordEncoder bCryptPasswordEncoder){ this.env = env; this.userService = userService; this.bCryptPasswordEncoder = bCryptPasswordEncoder; } @Override protected void configure(HttpSecurity http) throws Exception { // 권한 http.csrf().disable();// http.authorizeRequests().antMatchers("/users/**").permitAll(); // 모든걸 다 허용 http.authorizeRequests().antMatchers("/**") .hasIpAddress("192.168.45.163")// 해당 ip 허용 .and() .addFilter(getAuthenticationFilter()); // 이 필터를 통과하 데이터에 의해서만 허용한다. http.headers().frameOptions().disable(); // 프레임별로 데이터가 나눠져있는데 그걸 무시한다. } private AuthenticationFilter getAuthenticationFilter() throws Exception{ AuthenticationFilter authenticationFilter = new AuthenticationFilter(); authenticationFilter.setAuthenticationManager(authenticationManager()); return authenticationFilter; } @Override // 인증 (인증이 되야지만 권한 부여가 가능) protected void configure(AuthenticationManagerBuilder auth) throws Exception { auth.userDetailsService(userService).passwordEncoder(bCryptPasswordEncoder); }} 참고로 저는 스프링 부트 2.6.8 버전에 자바 1.8 버전을 사용합니다. 또한 참고로 UserController에 있는 리퀘스트 매핑은 @RequestMapping("/")  상태입니다.   그렇게 유레카 서버에서 user-service를 클릭하면 대략 다음과 같은 에러가 찍힙니다.. 검색해도 해결책은 안나오고... 뾰족한 수가 있을까요? 2022-08-19 16:58:55.562 ERROR 33392 --- [o-auto-1-exec-1]
