你需要什么:
- 位于 “/” 处的 DefaultServlet(推荐,这是 servlet 规范的要求)
- 这应该在“默认”的命名调度程序中(servlet规范的另一个要求)
- 具有自定义静态内容的备用 DefaultServlet,通过 init 参数进行配置
- 使用与“默认”不同的命名调度程序(以避免其他 servlet 规范功能之间的名称冲突)
- 您可以使用 来完成此操作
ServletHolder.setInitParameter(name,value)
- 确保将参数设置为(以解决“默认”命名调度程序的特殊情况)
pathInfoOnly
true
- 您自己的服务,提供动态内容。
