未为UserDetaildsServiceImpl定义的方法

Question

Good day我不确定发生了什么我怀疑eclipse，但在UserDetailsServiceImpl中它是定义的，因为我实现了spring的UserDetails服务，下面是我的代码

@Override
protected void doFilterInternal(HttpServletRequest request, HttpServletResponse response, FilterChain filterChain)
        throws ServletException, IOException {
    try {
        String jwt = parseJwt(request);
        if (jwt != null && jwtUtils.validateJwtToken(jwt)) {
            String username = jwtUtils.getUserNameFromJwtToken(jwt);

            UserDetails userDetails = userDetailsService.loadUserByUsername(username);
            UsernamePasswordAuthenticationToken authentication = new UsernamePasswordAuthenticationToken(
                    userDetails, null, userDetails.getAuthorities());
            authentication.setDetails(new WebAuthenticationDetailsSource().buildDetails(request));

            SecurityContextHolder.getContext().setAuthentication(authentication);
        }
    } catch (Exception e) {
        logger.error("Cannot set user authentication: {}", e);
    }

    filterChain.doFilter(request, response);
}

private String parseJwt(HttpServletRequest request) {
    String headerAuth = request.getHeader("Authorization");

    if (StringUtils.hasText(headerAuth) && headerAuth.startsWith("Bearer ")) {
        return headerAuth.substring(7, headerAuth.length());
    }

    return null;
}

这是让人头痛的一行“UserDetails UserDetails=userDetailsService.loadUserByUsername（username）”提前感谢您

使用

'@autowired'

UserDetailService userDetailsService；
