我需要在过滤器中使用自动装配。所以我用@Component注释了我的过滤器类，

import org.springframework.web.filter.GenericFilterBean;
@Component
public class TokenAuthorizationFilter extends GenericFilterBean {
    @Autowired
    public EnrollCashRepository enrollCashRepository;
}

然后我在SecurityConfig中如下添加我的过滤器，

   @Configuration
    @EnableWebMvcSecurity
    public class SecurityConfig extends WebSecurityConfigurerAdapter {

        @Override
        public void configure(WebSecurity webSecurity) throws Exception
        {
            webSecurity.ignoring().antMatchers(HttpMethod.GET, "/health");
        }
        @Override
        protected void configure(HttpSecurity http) throws Exception {
            http.addFilterBefore(new TokenAuthorizationFilter(), BasicAuthenticationFilter.class);  
            http.authorizeRequests().antMatchers("/api/**").authenticated();    
    }

我的问题是我的过滤器被@Component注释调用了两次。如果我删除@Component批注，它将仅调用一次。

然后我在Spring Boot主类中添加以下内容作为修复。然后，我在SecurityConfig中注释addFilterBefore行。

 @Bean
    public FilterRegistrationBean tokenAuthFilterRegistration() {
        FilterRegistrationBean filterRegistrationBean = new FilterRegistrationBean();
        filterRegistrationBean.setFilter(new PITokenAuthorizationFilter());
        filterRegistrationBean.setOrder(1);
        filterRegistrationBean.setEnabled(false);
        return filterRegistrationBean;
    }

但是然后我的过滤器被调用一次。但是即使我将setEnabled设置为true或false，当我调用其余api，http：// localhost：8080
/ api / myservice时，也会收到403
Forbiddon错误

我该如何解决在Spring过滤器中可以使用@Autowired的情况？

编辑：添加控制器和过滤器类，

@RestController
@RequestMapping(value = "/api")
public class SpringToolController { 
    @RequestMapping(value = "/myservice", method = RequestMethod.GET)
    public HttpEntity<String> myService() {
        System.out.println("-----------myService invoke-----------");
        return new ResponseEntity<String>(HttpStatus.OK);
    }
}



public class TokenAuthorizationFilter extends GenericFilterBean {
    public TokenAuthorizationFilter(EnrollCashRepository enrollCashRepository) {
        this.enrollCashRepository = enrollCashRepository;
    }

    public EnrollCashRepository enrollCashRepository;

    @Override
    public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain chain)
            throws IOException, ServletException {
        System.out.println("before PITokenAuthorizationFilter");
        chain.doFilter(servletRequest, servletResponse);
        System.out.println("after PITokenAuthorizationFilter");
    }

    public EnrollCashRepository getEnrollCashRepository() {
        return enrollCashRepository;
    }

    public void setEnrollCashRepository(EnrollCashRepository enrollCashRepository) {
        this.enrollCashRepository = enrollCashRepository;
    }

}
