Spring JavaConfig：为自定义Servlet添加映射 [英] Spring JavaConfig: Add mapping for custom Servlet

问题描述

在基于javaconfig的Spring 4.0项目中，如何将某个URL的映射添加到除Spring DispatcherServlet之外的Servlet。

In a javaconfig-based Spring 4.0 project, how can I add a mapping for a certain URL to a Servlet other than the Spring DispatcherServlet.

我的情况我是想要使用来自H2数据库的h2console，它通过servlet提供 org.h2.server.web.WebServlet

Im my case I want to use h2console from H2 database which is provided through the servlet org.h2.server.web.WebServlet

编辑：在即将推出的Spring Boot 1.3中，可以使用配置参数启用h2console： http://docs.spring.io/spring-boot/docs/current-SNAPSHOT/reference/htmlsingle/#boot-features- sql-h2-console

In the upcoming Spring Boot 1.3 the h2console can be enabled with a configuration parameter: http://docs.spring.io/spring-boot/docs/current-SNAPSHOT/reference/htmlsingle/#boot-features-sql-h2-console

启用它就像将这两行添加到 application.properties ：

Enabling it is as simple as adding these two lines to your application.properties:

spring.h2.console.enabled=true
spring.h2.console.path=/console

推荐答案

最简单的方法是使用初始化程序实现可怕的ctly WebApplicationInitializer和以下代码添加到 onStartup（ServletContext servletContext）方法;

The easiest way is to use initializer implementing directly WebApplicationInitializer and the add into onStartup(ServletContext servletContext) method following code;

ServletRegistration.Dynamic h2Servlet = servletContext.addServlet("h2Servlet", new org.h2.server.web.WebServlet());
h2Servlet.setLoadOnStartup(1);
h2Servlet.addMapping("/h2/*");
