No1：Nested in org.springframework.beans.factory.parsing.BeanDefinitionParsingException

2013-07-02 10:07:22.234:WARN::Nested in org.springframework.beans.factory.parsing.BeanDefinitionParsingException: Configuration problem: Failed to import bean definitions from relative location [spring/spring-db-context.xml]|Offending resource: class path resource [spring-root-context.xml]; nested exception is org.springframework.beans.factory.parsing.BeanDefinitionParsingException: Configuration problem: Unable to locate Spring NamespaceHandler for XML schema namespace [http://www.springframework.org/schema/tx]|Offending resource: class path resource [spring/spring-db-context.xml]|:org.springframework.beans.factory.parsing.BeanDefinitionParsingException: Configuration problem: Unable to locate Spring NamespaceHandler for XML schema namespace [http://www.springframework.org/schema/tx]|Offending resource: class path resource [spring/spring-db-context.xml]|
	at org.springframework.beans.factory.parsing.FailFastProblemReporter.error(FailFastProblemReporter.java:68)

原因：异常中提示Unable to locate Spring NamespaceHandler for XML schema namespace，说明找不到对应的XML文件，这时候你应该检查你的应用中是否缺少spring-tx的jar包，或者是你的maven工程缺少spring-tx的引用。

解决方法：

在工程中添加spring-tx的jar包，或者在pom.xml中添加如下代码

<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-tx</artifactId>
    <version>3.2.3.RELEASE</version>
</dependency>
