弹簧."schemaLocation ......必须有偶数个URI"

Question

我的xml文件中的代码段:

<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:aop="http://www.springframework.org/schema/aop" 
       xmlns:util="http://www.springframework.org/schema/util"
       xmlns:context="http://www.springframework.org/schema/context"

       xsi:schemaLocation="http://www.springframework.org/schema/beans

           http://www.springframework.org/schema/beans/spring-beans-3.1.xsd 
           http://www.springframework.org/schema/util 
           http://www.springframework.org/schema/util/spring-util.xsd
           http://www.springframework.org/schema/context/spring-context-3.1.xsd">

<!--            http://www.springframework.org/schema/aop  -->
<!--            http://www.springframework.org/schema/aop/spring-aop.xsd"> -->

    <context:component-scan base-package="myPackage" />

执行后我看到以下消息:

WARN [WrapperSimpleAppMain] [XmlBeanDefinitionReader]忽略XML验证警告org.xml.sax.SAXParseException; lineNumber:14; columnNumber:80; SchemaLocation:schemaLocation value =' http://www.springfr amework.org/schema/beans

http://www.springfra mework.org/schema/context/spring-context-3.1.xsd'必须有均匀URI的数量.at com.sun.org.apache.xerces.internal.util.ErrorHandlerWrapper.createSAXParseException(ErrorHandlerWrapper.java:198)

怎么解决这个问题吧？

Answer 1

你的schemaLocation价值应该是形式

namespace-name schema-location [namespace-name schema-location]

你错过了

http://www.springframework.org/schema/context

之前

http://www.springframework.org/schema/context/spring-context-3.1.xsd

因此应该是

xsi:schemaLocation="
           http://www.springframework.org/schema/beans
           http://www.springframework.org/schema/beans/spring-beans-3.1.xsd 
           http://www.springframework.org/schema/util 
           http://www.springframework.org/schema/util/spring-util-3.1.xsd  
           http://www.springframework.org/schema/context
           http://www.springframework.org/schema/context/spring-context-3.1.xsd">

请注意,我已将util架构更改为3.1版.不要混搭.使用所有相同的版本.
