spring boot 自定义错误页面

Posted 2020-10-08

spring boot 默认是whitelabel错误页面

java 8写法：

@Bean
public EmbeddedServletContainerCustomizer containerCustomizer() {
 
   return (container -> {
        ErrorPage error401Page = new ErrorPage(HttpStatus.UNAUTHORIZED, "/401.html");
        ErrorPage error404Page = new ErrorPage(HttpStatus.NOT_FOUND, "/404.html");
        ErrorPage error500Page = new ErrorPage(HttpStatus.INTERNAL_SERVER_ERROR, "/500.html");
 
        container.addErrorPages(error401Page, error404Page, error500Page);
   });
}

java 7写法

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

项目结构如下：
