tomcat 的503错误 (接上篇)

Posted 2023-04-25

搞了好久了，应该还是apache到tomcat之后的问题。 在apache的mod_jk.log里，有这样信息： [Thu Dec 27 13:44:23.375 2007] [2876:5112] [info] jk_connect.c (473): connect to 127.0.0.1:8009 failed (errno=61) [Thu Dec 27 13:44:23.375 2007] [2876:5112] [info] jk_ajp_common.c (891): Failed opening socket to (127.0.0.1:8009) (errno=61) [Thu Dec 27 13:44:23.375 2007] [2876:5112] [info] jk_ajp_common.c (1311): (ajp13) error connecting to the backend server (errno=61) [Thu Dec 27 13:44:23.375 2007] [2876:5112] [info] jk_ajp_common.c (2085): (ajp13) sending request to tomcat failed, recoverable operation attempt=2 [Thu Dec 27 13:44:23.375 2007] [2876:5112] [error] jk_ajp_common.c (2097): (ajp13) Connecting to tomcat failed. Tomcat is probably not started or is listening on the wrong port

Connecting to tomcat failed. Tomcat is probably not started or is listening on the wrong port
这个话表示tomcat不能被连接!看看是不是tomcat是不是没有启动!还是你把监听端口弄错了! 参考技术A 检查一下,数据库服务是否开启,Apache或tomcat是否开启！

希望我的回答对您有帮助！ 参考技术B 请您检查一下，数据库是否开启了 Apache 或 tomcat是否开启了！！！ 参考技术C 拒绝了仔细看看邻居

接上篇 checkbox数据的带入

  首先带回回来的json数据 先转换为树形结构 

才能方便之后遍历 添加数据，这是一段递归把数据变为树形结构的方法

// 把返回到LIST转为树形结构
function getTree(data, fid) {
    var result = [];
    var temp;
    for (var i = 0; i < data.length; i++) {
        if (data[i].fid == fid) {
            var obj = {
                "text" : data[i].gnmc,
                "gnid" : data[i].gnid,
                "yxbz" : data[i].yxbz
            };
            temp = getTree(data, data[i].gnid);
            if (temp.length > 0) {
                obj.children = temp;
            }
            result.push(obj);
        }
    }
    return result;
}

但注意：该方法使用的数据是这样存储的 fid是它的父级元素id  例如：gnid 13 的父级为gnid 12  ，gnid 12的父级为1 是这样的结构。

首先得到的数据 data = JSON.parse(data); //JSON.parse() 方法解析一个JSON字符串，构造由字符串描述的JavaScript值或对象

在转换为树形结构 var treeList = getTree(data, null);

对树形结构遍历 进行页面结构拼接 数据添加
