HttpJspPage (Java EE 5)

该接口的行为等同于 JspPage 的行为，除了 _jspService 方法的签名，现在该签名在 Java 类型系统中是可表示的，并且显式包含在该接口中。

The HttpJspPage interface describes the interaction that a JSP Page Implementation Class must satisfy when using the HTTP protocol.

The behaviour is identical to that of the JspPage, except for the signature of the _jspService method, which is now expressible in the Java type system and included explicitly in the interface.

JspPage

public void _jspService(HttpServletRequest request, HttpServletResponse response) throws ServletException, java.io.IOException
_jspService() 方法对应于 JSP 页面的正文。此方法由 JSP 容器自动定义，不得由 JSP 页面作者定义。

如果使用扩展属性指定了超类，则该超类可以选择在调用 _jspService() 方法之前（或之后）在其 service() 方法中执行某些操作。请参见 JSP 规范 JSP_Engine 章节中有关使用扩展属性的内容。

request	为 JSP 提供客户端请求信息。
response	协助 JSP 将响应发送到客户端。
Throws	ServletException: 如果 JSP 处理期间发生错误，则抛出该异常，并且容器应该采取适当操作清除请求。
Throws	java.io.IOException: 如果写入此页面的响应时发生错误，则抛出该异常。

英文文档：

_jspService

void _jspService(HttpServletRequest request,
                 HttpServletResponse response)
                 throws ServletException,
                        IOException

The _jspService()method corresponds to the body of the JSP page. This method is defined automatically by the JSP container and should never be defined by the JSP page author.

If a superclass is specified using the extends attribute, that superclass may choose to perform some actions in its service() method before or after calling the _jspService() method. See using the extends attribute in the JSP_Engine chapter of the JSP specification.

Parameters:

request - Provides client request information to the JSP.

response - Assists the JSP in sending a response to the client.

Throws:

ServletException - Thrown if an error occurred during the processing of the JSP and that the container should take appropriate action to clean up the request.

IOException - Thrown if an error occurred while writing the response for this page.
