项目中路径问题

Posted 2022-03-05 bulrush

    public static String getPath() 
        //得到当前的classpath的绝对路径的URI表示法
        String path=Thread.currentThread().getContextClassLoader().getResource("").toString();
        //  将/换成\  去掉file:   //去掉classes\   去掉第一个\,如 \D:\JavaWeb...
        path=path.replace(‘/‘, ‘\\‘).replace("file:", "").replace("classes\\", "").substring(1); 
        return path;
    
    
    //获得项目绝对路径
    public static String getProjectRootPath()   
        String rootPath=Thread.currentThread().getContextClassLoader().getResource("").getPath();    
        rootPath = rootPath.substring(1,rootPath.indexOf("WEB-INF"));    
        return rootPath;
    

classpath:只能服务器才能使用。客户端不能访问这个路径下的内容。

例如：项目名是test

D:/apacheTomcat/apache-tomcat-7.0.59/webapps/test/WEB-INF/classes/   

D:/apacheTomcat/apache-tomcat-7.0.59/webapps/test/ 

@Autowired
    private HttpServletRequest request;
    @Test
    public void testUrl()
        String schema = request.getScheme();
        String serverName = request.getServerName();
        // 端口号返回的是int类型
        int serverPort = request.getServerPort();
        String contextPath = request.getContextPath();
        String servletPath = request.getServletPath();
        System.out.println("协议:"+schema);
        System.out.println("服务器名称:"+ serverName);
        System.out.println("服务器端口号:"+ serverPort);
        System.out.println("项目名称:"+ contextPath);
        System.out.println("servlet路径:"+ servletPath);
