Springアプリケーションにgetリクエストを送信してJSON応答を取得しようとしています。たとえば、次のようにユーザ名を に送信しようとしました：http://localhost:5050/user/user1 応答がSpring RESTは同じデータの複数のJSON行を送信します
をコミットされた後にエラー
は、私は結果が、同じデータを複数のライン、それの多くを得るか）（のsendErrorを呼び出すことはできません。
コントローラ
@CrossOrigin("*") @RestController public class UsersRestController { @Autowired UserRepository userRepository; @RequestMapping(value = "/user/{username}",method = RequestMethod.GET) public User getUser(@PathVariable(name="username") String username) { return userRepository.findByUsername(username); }春は私に語ったが、このクラスのエラー：
public class AuthTokenFilter extends GenericFilterBean { private UserDetailsService customUserDetailsService; private String authTokenHeaderName = "x-auth-token"; public AuthTokenFilter(UserDetailsService userDetailsService) { this.customUserDetailsService = userDetailsService; } @Override public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain) throws IOException, ServletException { try { HttpServletRequest httpServletRequest = (HttpServletRequest) servletRequest; String authToken = httpServletRequest.getHeader(authTokenHeaderName); if (StringUtils.hasText(authToken)) { String username = TokenUtil.getUserNameFromToken(authToken); UserDetails userDetails = customUserDetailsService.loadUserByUsername(username); if (TokenUtil.validateToken(authToken, userDetails)) { UsernamePasswordAuthenticationToken token = new UsernamePasswordAuthenticationToken(userDetails, userDetails.getPassword(), userDetails.getAuthorities()); SecurityContextHolder.getContext().setAuthentication(token); } } // error in this line --------------> filterChain.doFilter(servletRequest, servletResponse); } catch (Exception ex) { System.out.println("somting went wrong"); } } }と同様に、このクラスはint型：私が見たときに
@Component public class SimpleCORSFilter implements Filter { @Override public void doFilter(ServletRequest req, ServletResponse res, FilterChain chain) throws IOException, ServletException { HttpServletRequest request = (HttpServletRequest) req; HttpServletResponse response = (HttpServletResponse) res; response.setHeader("Access-Control-Allow-Origin", "*"); response.setHeader("Access-Control-Allow-Credentials", "true"); response.setHeader("Access-Control-Allow-Methods", "POST, GET, PUT, OPTIONS, DELETE"); response.setHeader("Access-Control-Max-Age", "3600"); response.setHeader("Access-Control-Allow-Headers", "x-auth-token, Content-Type, Accept, X-Requested-With, remember-me"); // error in this line --------------> chain.doFilter(req, res); } @Override public void destroy() { } @Override public void init(FilterConfig filterConfig) throws ServletException { } }奇妙なことがありますusername = adminのように：
のhttp://localhost:5050/user/adminそれはうまく動作し、私は1つの行を得るエラーログ：

誰もが何か提案を持って間違っていましたか？事前に感謝
カスタムフィルタを挿入する場所は？コードを表示できますか？ – kxyz
@kxyz私はそれらを注入しなかった – alex
@kxyz私はちょうどこのように私のsecurityconfigurationにそれらを注入した： 'http.addFilterAfter（new AuthTokenFilter（customUserDetailsService）、BasicAuthenticationFilter.class）; http.addFilterBefore（新しいSimpleCORSFilter（）、BasicAuthenticationFilter.class）;でも同じ問題です – alex
