Question

假设我有这样的文档：

{ SequelizeConnectionRefusedError: connect ECONNREFUSED 127.0.0.1:3306
    at Utils.Promise.tap.then.catch.err (/Users/Stephen/Documents/_coding/hackReactorRemote/hrr34-fec/calendar-component/node_modules/sequelize/lib/dialects/mysql/connection-manager.js:139:19)

     errno: 'ECONNREFUSED',
     code: 'ECONNREFUSED',
     syscall: 'connect',
     address: '127.0.0.1',
     port: 3306,
     fatal: true },
  original:
   { Error: connect ECONNREFUSED 127.0.0.1:3306
    at TCPConnectWrap.afterConnect [as oncomplete] (net.js:1191:14)
     errno: 'ECONNREFUSED',

     syscall: 'connect',
     address: '127.0.0.1',
     port: 3306,
     fatal: true } }

我该如何处理呢？

我的意思是我要检查我的值是否等于此xml中的任何值。

<?xml version="1.0" encoding="UTF-8" ?>
 <main>
   <sub>1</sub>
   <sub>2</sub>
   <sub>3</sub>
   <sub>4</sub>
   <!-- and many, many elements like sub here don't know count of it -->
 </main>

有可能做这样的事情吗？

有两种实现方法。第一个是使用XPATH并获取值列表，并将其传递给iBatis调用。第二个方法是尝试将XML解组到POJO（使用JAXB等），然后提取值并调用iBatis。

XPath Example

在apache camel mybatis中使用多个标签传递和处理xml文档
