第一种写法
实现ErrorPageRegistrar,404.html放在项目的webapp文件夹中
1 2 3 4 5 6 7 8 9 10 11 12
| @Configuration public class ErrorPageConfig implements ErrorPageRegistrar { @Override public void registerErrorPages(ErrorPageRegistry registry) { ErrorPage[] errorPages = new ErrorPage[2]; errorPages[0] = new ErrorPage(HttpStatus.NOT_FOUND, "/404.html"); errorPages[1] = new ErrorPage(HttpStatus.INTERNAL_SERVER_ERROR, "/500.html"); registry.addErrorPages(errorPages); } }
|
第二种写法
Spring Boot2.0 之后的写法,404.html文件放在resources的static文件夹中
1 2 3 4 5 6 7 8 9 10 11 12
| @Configuration public class ErrorPageConfig { @Bean public WebServerFactoryCustomizer webServerFactoryCustomizer() { return (factory -> { ErrorPage errorPage404 = new ErrorPage(HttpStatus.NOT_FOUND, "/404.html"); factory.addErrorPages(errorPage404); }); } }
