未能读取架构文档“http://www.springframework.org/schema/beans/spring-beans-3.0.xsd”

Question

在启动我的 Spring 应用程序时，我收到以下错误：

WARNING: Ignored XML validation warning
org.xml.sax.SAXParseException: schema_reference.4: Failed to read schema document     
'http://www.springframework.org/schema/beans/spring-beans-3.0.xsd', because
1) could not find the document;
2) the document could not be read;
3) the root element of the document is not <xsd:schema>.

我的springapp-servlet.xml如下：

<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"        
xmlns:aop="http://www.springframework.org/schema/aop"      
xsi:schemaLocation="http://www.springframework.org/schema/beans   
http://www.springframework.org/schema/beans/spring-beans-3.0.xsd">
<bean name="/hello.htm" class="springapp.web.HelloController"/>
</beans>

请提出建议。

当我收到此错误消息时，这仅仅是因为我的 CLASSPATH 中缺少一个 jar。一些 spring 应用程序似乎对 spring jars 非常渴望。我的应用最终需要类路径中的所有这些：

${OTS_DIR}/org.springframework.aop-${VERSION}.jar:\
${OTS_DIR}/org.springframework.aspects-${VERSION}.jar:\
${OTS_DIR}/com.springsource.org.aopalliance-${AOPALLIANCE_VER}.jar:\
${OTS_DIR}/org.springframework.asm-${VERSION}.jar:\
${OTS_DIR}/org.springframework.beans-${VERSION}.jar:\
${OTS_DIR}/org.springframework.context-${VERSION}.jar:\
${OTS_DIR}/org.springframework.core-${VERSION}.jar:\
${OTS_DIR}/org.springframework.expression-${VERSION}.jar:\
${OTS_DIR}/org.springframework.jdbc-${VERSION}.jar:\
${OTS_DIR}/org.springframework.jms-${VERSION}.jar:\
${OTS_DIR}/org.springframework.orm-${VERSION}.jar:\
${OTS_DIR}/org.springframework.transaction-${VERSION}.jar:\
${OTS_DIR}/org.springframework.instrument-${VERSION}.jar
