随着Springboot从2.7.2更新到3.2.0，现在Filter类开始抛出异常
原因：org. springframework. Boot . web. server. WebServerException：无法在org. springframework. Boot . web. embedded. tomcat.

看起来像抛出异常的代码

@Configuration
public class WebMvcConfig implements  WebMvcConfigurer  {

    @Value("${system.debug.enabled:false}")
    private boolean debugEnabled;

    @Override
    public void addInterceptors(InterceptorRegistry registry) {
        registry.addInterceptor(httpHeaderInterceptor());
    }

    @Override
    public void addCorsMappings(CorsRegistry registry) {
        registry.addMapping("/log/**").allowedOrigins("*")
                .allowedMethods("POST", "GET", "PUT", "PATCH", "OPTIONS", "DELETE")
                .allowedHeaders("header1", "header2", "header3")
                .allowedHeaders("Origin", "Authorization", "X-Requested-With", "Content-Type", "Accept")
                .allowCredentials(false).maxAge(3600);
    }

    @Bean
    public HandlerInterceptor httpHeaderInterceptor() {
        return (HandlerInterceptor) new HttpHeaderInterceptor();
    }
     
    private FilterRegistrationBean newFilterRegistrationBean(Filter filter, int order) {
        final FilterRegistrationBean filterRegistrationBean = new FilterRegistrationBean();
        filterRegistrationBean.setOrder(order);
        filterRegistrationBean.addUrlPatterns("/*");
        return filterRegistrationBean;
    }

    @Bean
    public FilterRegistrationBean stopWatchFilter() {
        Filter filter = debugEnabled ? new StopWatchFilter() : new NoopFilter();
        FilterRegistrationBean filterRegistrationBean = newFilterRegistrationBean(filter, 1);
        return filterRegistrationBean;
    }

    @Bean
    public FilterRegistrationBean gzipFilter() {
        GZipRequestFilter gzipRequestFilter = new GZipRequestFilter();
        return newFilterRegistrationBean(gzipRequestFilter, 2);
    }

    @Bean
    public FilterRegistrationBean registerOpenSessionInViewFilterBean() {
        OpenEntityManagerInViewFilter openEntityManagerInViewFilter = new OpenEntityManagerInViewFilter();
        return newFilterRegistrationBean(openEntityManagerInViewFilter, 1);
    }
}

字符串
根据我的理解，

@Bean
    public FilterRegistrationBean gzipFilter() {
        GZipRequestFilter gzipRequestFilter = new GZipRequestFilter();
        return newFilterRegistrationBean(gzipRequestFilter, 2);
    }

    @Bean
    public FilterRegistrationBean registerOpenSessionInViewFilterBean() {
        OpenEntityManagerInViewFilter openEntityManagerInViewFilter = new OpenEntityManagerInViewFilter();
        return newFilterRegistrationBean(openEntityManagerInViewFilter, 1);
    }

型
但是place类正在初始化，但仍然告诉NULL。删除此代码后，它将启动服务器。
