为什么我仍然收到此消息?
Exception in thread "main" org.springframework.beans.factory.parsing.BeanDefinitionParsingException: Configuration problem: Failed to import bean definitions from relative location [../beans/Character.xml]
Offending resource: class path resource [spring/config/beanLocations.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/beans/Character.xml]
at org.springframework.beans.factory.parsing.FailFastProblemReporter.error(FailFastProblemReporter.java:72)
我读过很多关于这个问题的帖子,并根据它们配置了我的 xml-s。
我的违规 xml 如下所示:
<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"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/tx
http://www.springframework.org/schema/tx/spring-tx.xsd">
<!-- Character Data Access Object -->
<bean id="characterDao" class="com.got.common.dao.CharacterDao" >
<property name="sessionFactory" ref="sessionFactory"/>
</bean>
<tx:annotation-driven/>
<bean id="transactionManager" class="org.springframework.orm.hibernate5.HibernateTransactionManager">
<property name="sessionFactory" ref="sessionFactory"/>
</bean>
</beans>
Spring-tx 包含在我的 pom.xml 中:
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-tx</artifactId>
<version>5.0.2.RELEASE</version>
</dependency>
beanLocations.xml

我不确定 aop 是否也必须包含在内,但它就在那里。 这个命名空间有什么问题吗?我不想再费劲了,所以请告诉我找不到这个命名空间的原因。
最佳答案
该问题可能是由于您使用的 assembly-plugin 引起的,它不理解 spring 处理程序机制并覆盖了 spring.handlers
文件中的处理程序定义。此线程中讨论了行为:Idea to avoid that spring.handlers/spring.schemas get overwritten when merging multiple spring dependencies in a single jar
为了避免这个问题,一种选择是使用阴影插件来达到您的目的,如建议的here .
