  mojo development model.

  In order to really achieve this, we need mojo configurations (which are
  provided both in terms of static expressions that are just looked up, and
  in terms of user-provided configuration from properties or the POM).
  If these mojos are to be first-class components, the configuration from these
  various sources must be consolidated and injected using the container.

       The fact that a project has a distinct pom.xml should indicate a separate
       release cycle that is also distinct to that project, so a concrete version
       declaration is required.

   - [name] tells maven what the user-friendly name of this project is. The name
       element is similar to artifactId in that it is a unique descriptor for

在任何*路径操作*收到`request`前,可以添加要和请求一起运行的代码.

也可以在*响应*生成但是返回之前添加代码.

例如你可以添加自定义请求头 `X-Process-Time` 包含以秒为单位的接收请求和生成响应的时间:
