本文深入探讨了_jspService方法的实现细节，包括初始化页面上下文、获取异常并设置服务器错误状态的过程。此方法用于处理HTTP请求，在Java Web应用中扮演重要角色。
public void _jspService(HttpServletRequest request,
HttpServletResponse response)
throws java.io.IOException, ServletException
{
JspFactory _jspxFactory = null;
PageContext pageContext = null;
HttpSession session = null;
ServletContext application = null;
ServletConfig config = null;
JspWriter out = null;
Object page = this;
...
...
Throwable exception =
org.apache.jasper.runtime.JspRuntimeLibrary.getThrowable(request);
if (exception != null) {
response.setStatus(HttpServletResponse.SC_INTERNAL_SERVER_ERROR);
}
HttpServletResponse response)
throws java.io.IOException, ServletException
{
JspFactory _jspxFactory = null;
PageContext pageContext = null;
HttpSession session = null;
ServletContext application = null;
ServletConfig config = null;
JspWriter out = null;
Object page = this;
...
...
Throwable exception =
org.apache.jasper.runtime.JspRuntimeLibrary.getThrowable(request);
if (exception != null) {
response.setStatus(HttpServletResponse.SC_INTERNAL_SERVER_ERROR);
}
