    activemq 5.2 最近项目要用到JMS,因为用tomcat容器,所以采用了开源的ActiveMQ  消息中间件提供JMS支持。但是在spring2.5和activemq5.2集成的时候出现了点问题,首先列出activemq-import-beans.xml的内容: Java代码  1.<beans xmlns="http://www.springframework.org/schema/beans"   2.  xmlns:amq="http://activemq.org/config/1.0"  3.  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  4.  xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd  5.                                    http://activemq.org/config/1.0 http://activemq.apache.org/schema/core/activemq.xsd">  运行测试程序出现以下异常: Java代码  1.Caused by: org.xml.sax.SAXParseException: TargetNamespace.1: Expecting namespace 'http://activemq.org/config/1.0', but the target namespace of the schema document is 'http://activemq.apache.org/schema/core'.  2.    at

通过阅读异常信息发现时XSD名称空间不对,所以赶紧打开activemq-core-5.2.0.jar/META-INF/目录中的spring.schemas查看,发现"http\://activemq.apache.org/schema/core/activemq-core.xsd=activemq.xsd" 于是乎又打开activemq.xsd查个究竟,以下为activemq5.2的activemq.xsd文件一部分: Java代码  1.<xs:schema elementFormDefault='qualified'  2.           targetNamespace='http://activemq.apache.org/schema/core'  3.           xmlns:xs='http://www.w3.org/2001/XMLSchema'  4.           xmlns:tns='http://activemq.apache.org/schema/core'>  噢,原来目标名称空间不一致啊。于是赶紧去改activemq-import-beans.xml文件的配置,修改如下: Java代码  1.<?xml version="1.0" encoding="UTF-8"?>   2.<beans xmlns="http://www.springframework.org/schema/beans"   3.xmlns:xsi=http://www.w3.org/2001/XMLSchema-instance    4.xmlns:amq="http://activemq.apache.org/schema/core"  //这个地方很关键,amq对应的XSD名称空间名称要和activemq.xsd的一致  5.xsi:schemaLocation="   6.http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd  7.http://activemq.apache.org/schema/core http://activemq.apache.org/schema/core/activemq.xsd">   呵呵,到这里以为问题已经搞定,但是运行测试后,又发现一个新的问题,异常信息如下: Java代码  1.org.xml.sax.SAXParseException: schema_reference.4: Failed to read schema document 'http://activemq.apache.org/schema/core/activemq.xsd', because 1) could not find the document;   2.               2) the document could not be read;   3.               3) the root element of the document is not <xsd:schema>.  查看了异常信息后,发现可能是spring无法定位到http://activemq.apache.org/schema/core/activemq.xsd,于是又一次打开activemq-core-5.2.0.jar/META-INF的spring.schemas,内容如下: Java代码  1.http\://activemq.org/config/1.0=activemq.xsd  2.http\://activemq.org/config/1.0/1.0.xsd=activemq.xsd  3.http\://activemq.apache.org/schema/core=activemq.xsd  4.http\://activemq.apache.org/schema/core/activemq-core.xsd=activemq.xsd  呵呵,发现问题了吗?初看没啥问题,但是仔细一看,噢,原来http\://activemq.apache.org/schema/core/activemq-core.xsd=activemq.xsd 与http://activemq.apache.org/schema/core/activemq.xsd 不匹配,呵呵,知道问题根源了,现在时解决办法,解决办法有两种: 第一种:修改activemq-import-beans.xml文件的“http://activemq.apache.org/schema/core/activemq.xsd ”这句为:http://activemq.apache.org/schema/core/activemq-core.xsd(这个就是activemq jar包中spring.schemas文件的最后一行,但是注意:http\://要改为http://) 第二种:在classpath目录中,新建META-INF/spring.schemas文件,然后增加一下内容: Java代码  1.http\://activemq.apache.org/schema/core/activemq-core.xsd=activemq.xsd  这个时候重新运行测试,发现一切OK。哈。。 转:http://xmuzyq.iteye.com/blog/365989
