@Value()读取配置文件属性，读出值为null的问题

@Component
public class JwtFilter extends GenericFilterBean{
 
    @Value("${jwt.header}")
    private String header;  //此处无法注入 值为 null
在config中将此filter注册给spring

@Configuration
@AutoConfigureAfter(JwtFilter.class)
public class JwtConfig {
    @Bean
    public FilterRegistrationBean jwtFilter() {
        final FilterRegistrationBean registrationBean = new FilterRegistrationBean();
        registrationBean.setFilter(new JwtFilter());  //率先执行
        String[] paths = jwtProperty.getCheckPath().split(",");
        for (String p : paths){
            registrationBean.addUrlPatterns(p);
            System.out.println(p);
        }
        return registrationBean;
    }
}

@Component
@Data
public class JwtProperty {
 
    @Value("${jwt.header}")
    private String header;
 
    @Value("${jwt.tokenHead}")
    private String tokenHead;
 
    @Value("${jwt.secret}")
    private String secret;
 
    @Value("${jwt.checkPath}")
    private String checkPath;
 
    @Value("${jwt.expiration}")
    private Integer expire;
 
    public JwtProperty() {
    }
}

@Configuration
public class JwtConfig {
 
 
    @Autowired
    private JwtProperty jwtProperty;
