我正在尝试在Spring启动应用程序中自动装配一个类。但Spring没有给出任何实例，它给出了null。
public class JWTAuthorizationFilter extends BasicAuthenticationFilter {
public JWTAuthorizationFilter( AuthenticationManager authManager )
{
super(authManager);
}
@Autowired
private JWTUtil jwtUtil;
@Override
protected void doFilterInternal( HttpServletRequest req, HttpServletResponse res, FilterChain chain )
throws IOException, ServletException
{
String jwt = req.getHeader(SecurityConstants.HEADER_STRING);
if( jwt == null || !jwt.startsWith(SecurityConstants.TOKEN_PREFIX) )
{
chain.doFilter(req, res);
return;
}
if(!jwtUtil.validateToken(jwt))
{
chain.doFilter(req, res);
return;
}
UsernamePasswordAuthenticationToken authentication = getAuthentication(req);
SecurityContextHolder.getContext().setAuthentication(authentication);
chain.doFilter(req, res);
}
}
JWTUtil jwtUtil获得空值。我已将JWTUtil.java标记为@Component注释，但仍然无效。
@Component
public class JWTUtil {
private static final Logger logger = LoggerFactory.getLogger(JWTUtil.class);
@Autowired
private UserModelRepository userModelRepository;
public Boolean validateToken( String jwt )
{
Claims claims = Jwts.parser().setSigningKey(SecurityConstants.SECRET)
.parseClaimsJws(jwt.replace(SecurityConstants.TOKEN_PREFIX, "")).getBody();
Date createdAt = claims.getIssuedAt();
String mobileNumber = claims.getSubject();
Optional<UserModel> userModelOptional = userModelRepository.findByMobileNumberAndIsActiveTrue(mobileNumber);
if( !userModelOptional.isPresent() )
{
return false;
}
UserModel userModel = userModelOptional.get();
Calendar logoutTime = userModel.getLogoutTime();
if( null != logoutTime )
{
Date logoutDate = logoutTime.getTime();
if( logoutDate.before(createdAt) ) // new token
{
return true;
}
}
logger.info("Invalid token....issued before last logout");
return false;
}
}
这里也是
@Autowired
private UserModelRepository userModelRepository;
变为空。为什么会这样？
