Question

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

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注释，它只会调用一次。

然后我在下面添加我的Spring启动主类中的修复程序。然后我在SecurityConfig中评论addFilterBefore行。

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

但是我的过滤器会被调用一次。但即使我使setEnabled为true或false，当我调用我的rest api时，我得到403 Forbiddon错误，http://localhost:8080/api/myservice

我如何解决这种情况，我可以在Spring Filter中使用@Autowired？

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;
    }

}

删除FilterRegistrationBean并在TokenAuthorizationFilter内初始化SecurityConfig，如下所示：

@Configuration
@EnableWebMvcSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {

    @Autowired
    public EnrollCashRepository enrollCashRepository;

    @Override
    public void configure(WebSecurity webSecurity) throws Exception
    {
        webSecurity.ignoring().antMatchers(HttpMethod.GET, "/health");
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception 
    {
        http.addFilterBefore(tokenAuthorizationFilter(), BasicAuthenticationFilter.class);  
        http.authorizeRequests().antMatchers("/api/**").authenticated();    
    }

    private TokenAuthorizationFilter tokenAuthorizationFilter() 
    {
        return new TokenAuthorizationFilter(enrollCashRepository);
    }
}

删除@Autowired和@Component注释，并使用构造函数注入设置EnrollCashRepository：

import org.springframework.web.filter.GenericFilterBean;

public class TokenAuthorizationFilter extends GenericFilterBean {

    private final EnrollCashRepository enrollCashRepository;

    public TokenAuthorizationFilter(EnrollCashRepository enrollCashRepository) 
    {
        this.enrollCashRepository = enrollCashRepository
    }
}

我现在为我的工人类添加了一个测试过滤器，它运行正常。以下是与之相关的代码。

过滤

@Component
public class TestFilter extends GenericFilterBean {

private static final Logger logger = LoggerFactory.getLogger(TestFilter.class);

@Autowired
UserService userService;

 @Override
 public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {
     logger.error("=====================AWESOME=======================");
     chain.doFilter(request, response);
     userService.activate("123"); //this works
 }

}

App Security Config

@Configuration
@EnableWebSecurity
public class AppSecurityConfig extends WebSecurityConfigurerAdapter {

@Autowired
private TestFilter testFilter;

     @Override
     protected void configure(HttpSecurity http) throws Exception {
     //loginFailureHandler.setDefaultFailureUrl("/login?error=true");
     http.addFilterBefore(testFilter, BasicAuthenticationFilter.class);
     //Http other config here.
 }
}

App Config

@Configuration
@ImportResource({
    "classpath*:/context.xml"
})
@PropertySources(
    @PropertySource({
            "classpath:/application.yml"
    })
)
@Import({AppSecurityConfig.class, WebConfig.class,TestFilter.class})
public class AppConfig {
}

将@Autowired与SpringBoot中配置的过滤器一起使用
