    1. Jfinal 使用ajax 与后台交互
    
    <!DOCTYPE html>
    <html lang="en">
    <head>
        <script src='http://cdnjs.cloudflare.com/ajax/libs/jquery/2.1.3/jquery.min.js'></script>
        <meta charset="UTF-8">
        <title>Title</title>
    </head>
    <body>
    <input type="text" id="fname" value="222" />
    <button onclick="subAction()">测试</button>
    <script type="application/javascript">
        function subAction() {
            $.ajax({
                type: "POST",
                dataType : "json",
                url: "registe",
                data: {
                    fname:$('#fname').val(),
                    lname:"22",
                    email:"222",
                    password:"2222",
                },
                success: function(res){
                    alert(res.msg);
                }
            });
        }
    </script>
    这是主页
    </body>
    </html>
    
        public void registe() {
            String fname = getPara("fname");
            setAttr("result", "1");
            setAttr("msg", fname);
            renderJson();
        }
    
    
    1. 加载全局路径 cxt
      handlers.add(new ContextPathHandler("cxt"));
    
    1. log4内置日志

    log4j.properties

    # log4j.rootLogger=WARN, stdout, file
    log4j.rootLogger=ERROR, stdout, file
    log4j.appender.stdout=org.apache.log4j.ConsoleAppender
    log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
    log4j.appender.stdout.layout.ConversionPattern=%n%-d{yyyy-MM-dd HH:mm:ss}%n[%p]-[Thread: %t]-[%C.%M()]: %m%n
    
    # Output to the File
    log4j.appender.file=org.apache.log4j.DailyRollingFileAppender
    log4j.appender.file.DatePattern='_'yyyy-MM-dd'.log'
    log4j.appender.file.File=./jfinal_demo.log
    log4j.appender.file.layout=org.apache.log4j.PatternLayout
    log4j.appender.file.layout.ConversionPattern=%n%-d{yyyy-MM-dd HH:mm:ss}%n[%p]-[Thread: %t]-[%C.%M()]: %m%n
