Spring Boot2.2.X中Tomcat配置 错误定制

1: Tomcat定制

EmbeddedServletContainerCustomizer 已久废弃 按照下面的方式来处理 通过的类的配置

@Component
public class TomcatConfig implements WebServerFactoryCustomizer<ConfigurableServletWebServerFactory> {

    @Override
    public void customize(ConfigurableServletWebServerFactory server) {
        server.setDisplayName("hello kugou");
        server.setPort(8082);
    }
}

2: 错误定制

@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);
    }
}
