Spring 在+publicId+和+systemId+之间需要有空格

今天配置Spring,遇到一个很奇葩的问题:

Spring.xml的配置文件内容:

<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans"    xmlns:context="http://www.springframework.org/schema/context"     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"    xmlns:tx="http://www.springframework.org/schema/tx"    xsi:schemaLocation="http://www.springframework.org/schema/beans      http://www.springframework.org/schema/beans/spring-beans-3.0.xsd      http://www.springframework.org/schema/context            http://www.springframework.org/schema/tx      http://www.springframework.org/schema/tx/spring-tx-3.0.xsd            http://www.springframework.org/schema/context/spring-context.xsd      ">

测试出错:

Tests in error:   instanceSpring(com.qunar.studyspring.SpringTest): Line 1 in XML document from class path resource [spring.xml] is invalid; nested exception is org.xml.sax.SAXParseException; systemId: http://www.springframework.org/schema/tx/; lineNumber: 1; columnNumber: 55; 在 publicId 和 systemId 之间需要有空格。

百思不得其解,后来在网络上搜索了半天,结论就是:前一个是publicID,后一个是SystemId,是一一对应的,位置不能颠倒

http://www.springframework.org/schema/beans publicIDhttp://www.springframework.org/schema/beans/spring-beans-2.5.xsd SystemId

修改之后:

<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans"    xmlns:context="http://www.springframework.org/schema/context"     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"    xmlns:tx="http://www.springframework.org/schema/tx"    xsi:schemaLocation="http://www.springframework.org/schema/beans      http://www.springframework.org/schema/beans/spring-beans-3.0.xsd      http://www.springframework.org/schema/context            http://www.springframework.org/schema/context/spring-context.xsd      http://www.springframework.org/schema/tx      http://www.springframework.org/schema/tx/spring-tx-3.0.xsd            ">

黑色部分就是给我留下深刻记忆的部分,次序颠倒了
