使用Sintra开发文档系统

安装

ruby && gem

对于windows环境，最简单的方式是下载一个installer，双击运行就可以了。

sinatra

Spring MVC其实提供了一些好用的util类：

import org.springframework.web.util.WebUtils;

Cookie cookie = WebUtils.getCookie(request, "SECURITY_TOKEN");

Spring interceptor

配置

<!-- Configures Handler Interceptors --> 
<mvc:interceptors>  
    <!-- This bit of XML will intercept all URLs - which is what you want in a web app -->
    <bean class="me.arganzheng.study.api.container.interceptor.AuthorizationInterceptor" />

如何打印ibatis拼凑的动态SQL语句

log4j.logger.java.sql.PreparedStatement=debug
log4j.logger.java.sql.Connection=debug

将打印出Connection和Statement信息：

[DEBUG] 11:48:17 Connection - {conn-100000} Connection

[DEBUG] 11:48:17 Connection - {conn-100000} Preparing Statement: select api.id from t_api_metadata_api api, t_api_metadata_module module where api.module_id=module.id and api.source = ? and api.name = ? and api.module_id = ? and module.name = ?

JS实现一段时间后自动调转页面

setTimeout(function(){
	window.location.href="./modules.xhtml?source=${source}";
	}, 2000
);

	// empty constructor
	public ApiDao() {

	// autowired constructor
	// i dont know why, but i cant autowired sqlMapClient directly
	// it will cause java.lang.IllegalArgumentException: Property 'sqlMapClient' is required
