api -servletContext
添加servlet监听器.因为springmvc其实全局就只有一个dispatchservlet,其生命周期几乎等同于application的生命周期,所以其api获取的数据可以直接变成静态变量,提供给工具类使用
springboot中添加servlet生命周期监听器:
@WebListener
public class MyListener implements ServletContextListener {
private ServletContext context = null;
/* 这个方法在Web应用服务被移除，没有能力再接受请求的时候被调用。
*/
public void contextDestroyed(ServletContextEvent event){
//Output a simple message to the server's console
System.out.println("The Simple Web App. Has Been Removed");
this.context = null;
}
// 这个方法在Web应用服务做好接受请求的时候被调用。
public void contextInitialized(ServletContextEvent event){
this.context = event.getServletContext();
ContextPathUtil.setContext(this.context);
context.setAttribute("basePath","");
System.out.println("The Simple Web App. Is Ready");
org.apache.ibatis.logging.LogFactory.useSlf4jLogging();
}
}
ServletContext的api
private void logServelet(ServletContext context) {
log("getContextPath:"+context.getContextPath());
log("getServerInfo:"+context.getServerInfo());
log("getRealPath(/):"+context.getRealPath("/"));
//log("getRealPath(/):"+context.getres("/"));
}
getContextPath:
getServerInfo:Apache Tomcat/8.5.15
getRealPath(/):C:\Users\Administrator\AppData\Local\Temp\tomcat-docbase.608303050980735220.8080\
如何获取一个本服务器中一个静态资源的真实文件路径?todo
获取本项目的绝对磁盘路径
添加启动监听,拿到静态数据
http://blog.csdn.net/mytt_10566/article/details/58599243
获取本项目的完整url根路径(域名+项目名)
没有静态获取方式,都需要从request中获取
url和本地路径的映射
- 项目内静态资源的映射
- 上传下载时,url与项目外绝对路径的映射
