JFinalFilter 中
private Handler handler; //子类中的ActionHandler.actionMapping包装了 链接跟具体某个方法的对应关系(action),handle方法里面的ActionInvocation包装了Interceptor[],Controller
public void init(FilterConfig filterConfig)throws ServletException {
createJFinalConfig(filterConfig.getInitParameter("configClass"));
if (jfinal.init(jfinalConfig, filterConfig.getServletContext()) ==false)
thrownew RuntimeException("JFinal init error!");
handler = jfinal.getHandler();
constants = Config.getConstants();
encoding = constants.getEncoding();
jfinalConfig.afterJFinalStart();
String contextPath = filterConfig.getServletContext().getContextPath();
contextPathLength = (contextPath ==null ||"/".equals(contextPath) ? 0 : contextPath.length());
}
然后 去看 (jfinal.init
private ActionMapping actionMapping; //类似于/blog/update=com.jfinal.core.Action@91cd9ec
boolean init(JFinalConfig jfinalConfig, ServletContext servletContext) {
this.servletContext = servletContext;
this.contextPath = servletContext.getContextPath();
initPathUtil();
Config.configJFinal(jfinalConfig);// startplugin and init logger factory in this method
constants = Config.getConstants();
initActionMapping();
initHandler();
initRender();
initOreillyCos();
initTokenManager();
returntrue;
}
重点去看initActionMapping()
private void initActionMapping() {
actionMapping = new ActionMapping(Config.getRoutes(), Config.getInterceptors());
actionMapping.buildActionMapping();
}
buildActionMapping()这边初始话的时候 就把所有的处理器 (handle) 和 访问地址一一对应,并且 handle中的拦截器 都通过Config.getInterceptors()传递过去了
