JAVA常見異常集錦（持續更新）

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：異常中提示Unable to locate Spring NamespaceHandler for XML schema namespace，說明找不到對應的XML檔案，這時候你應該檢查你的應用中是否缺少spring-tx的jar包，或者是你的maven工程缺少spring-tx的引用。

解決方案：

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

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