关于spring boot中 EmbeddedServletContainerCustomizer
作者:互联网
EmbeddedServletContainerCustomizer这个在spring boot2.X的版本中就不再提供支持了貌似2.0版本还能用 ,用来提供对异常的处理。在支持EmbeddedServletContainerCustomizer的springboot版本中我们可以类似这样来配置异常处理和跳转
package com.dabai.springtest.error; import org.springframework.boot.web.server.ErrorPage; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; import org.springframework.http.HttpStatus; @Configuration public class ErrorPageConfig { @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); } }; } }
在不支持的情况下需要这样
package com.dabai.springtest.error; import org.springframework.boot.web.server.ErrorPage; import org.springframework.boot.web.server.ErrorPageRegistrar; import org.springframework.boot.web.server.ErrorPageRegistry; import org.springframework.http.HttpStatus; import org.springframework.stereotype.Component; @Component public class ErrorPageConfig implements ErrorPageRegistrar { @Override public void registerErrorPages(ErrorPageRegistry registry) { ErrorPage error400Page=new ErrorPage(HttpStatus.BAD_REQUEST,"/error400" ); ErrorPage error401Page=new ErrorPage(HttpStatus.UNAUTHORIZED,"/error401"); ErrorPage error500Page=new ErrorPage(HttpStatus.INTERNAL_SERVER_ERROR,"/error500"); registry.addErrorPages(error400Page,error401Page,error500Page); } }
其中
ErrorPageRegistrar接口:
// // Source code recreated from a .class file by IntelliJ IDEA // (powered by Fernflower decompiler) // package org.springframework.boot.web.server; @FunctionalInterface public interface ErrorPageRegistrar { void registerErrorPages(ErrorPageRegistry registry); }
// // Source code recreated from a .class file by IntelliJ IDEA // (powered by Fernflower decompiler) // package org.springframework.boot.web.server; @FunctionalInterface public interface ErrorPageRegistry { void addErrorPages(ErrorPage... errorPages); }
