配置问题:无法找到XML架构命名空间的Spring NamespaceHandler [http://www.springframework.org/schema/tx]

Question

在JBOSS服务器启动期间我收到此错误,

19:44:59,307 ERROR [STDERR] 23813 [main] ERROR org.springframework.web.context.ContextLoader - Context initialization failed
19:44:59,307 ERROR [STDERR] org.springframework.beans.factory.parsing.BeanDefinitionParsingException: Configuration problem: Unable to locate Spring NamespaceHandler for XML schema namespace [http://www.springframework.org/schema/tx]

这就是我的application.xml的样子,

<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:tx="http://www.springframework.org/schema/tx"
    xmlns:aop="http://www.springframework.org/schema/aop"
    xsi:schemaLocation="http://www.springframework.org/schema/beans
    http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
    http://www.springframework.org/schema/tx
    http://www.springframework.org/schema/tx/spring-tx-2.5.xsd
    http://www.springframework.org/schema/aop
    http://www.springframework.org/schema/aop/spring-aop-2.5.xsd">

我使用的是弹簧2.5.6 ...有关错误的任何建议..

Answer 1

这可能是因为您丢失了spring-tx*.jar类路径中的文件.您可以验证此文件是否在类路径中.

Answer 2

供将来参考:

如果您使用Maven,也许您忘记了spring-tx依赖.

    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-tx</artifactId>
        <version>${org.springframework.version}</version>
    </dependency>
