SpringBoot 错误页配置

一、spring1.x中处理方式

@Bean
    public EmbeddedServletContainerCustomizer containerCustomizer() {
        return new EmbeddedServletContainerCustomizer() {
            @Override
            public void customize(ConfigurableEmbeddedServletContainer container) {
                ErrorPage error401Page = new ErrorPage(HttpStatus.UNAUTHORIZED, "/401");
                ErrorPage error405Page = new ErrorPage(HttpStatus.METHOD_NOT_ALLOWED, "/405");
                ErrorPage error404Page = new ErrorPage(HttpStatus.NOT_FOUND, "/404");
                ErrorPage error500Page = new ErrorPage(HttpStatus.INTERNAL_SERVER_ERROR, "/500");
 
                container.addErrorPages(error401Page,error405Page, error404Page, error500Page);
            }
        };
    }

二、spring2.x中处理方式

@Component
public class ErrorConfig implements ErrorPageRegistrar {
 
    @Override
    public void registerErrorPages(ErrorPageRegistry registry) {
        ErrorPage error400Page = new ErrorPage(HttpStatus.BAD_REQUEST, "/error400Page");
        ErrorPage error401Page = new ErrorPage(HttpStatus.UNAUTHORIZED, "/error401Page");
        ErrorPage error404Page = new ErrorPage(HttpStatus.NOT_FOUND, "/error404Page");
        ErrorPage error500Page = new ErrorPage(HttpStatus.INTERNAL_SERVER_ERROR, "/error500Page");

        registry.addErrorPages(error400Page,error401Page,error404Page,error500Page);
    }
}
