我能够使用Maven编译并启动Spring项目:
mvn -e clean compile exec:java -Dexec.mainClass=de.fraunhofer.fkie.tet.vmware.manager.Test
但是,当我使用maven-assembly-plugin(包括applicationContext.xml)将所有jar组装到一个文件中时,Exception在java执行过程中总是会得到一个:
maven-assembly-plugin
applicationContext.xml
Exception
java -cp target/test-jar-with-dependencies.jar:. de.fraunhofer.fkie.tet.vmware.manager.Test INFO: Loading XML bean definitions from class path resource [applicationContext.xml] Sep 6, 2010 10:37:21 AM org.springframework.util.xml.SimpleSaxErrorHandler warning WARNING: Ignored XML validation warning org.xml.sax.SAXParseException: schema_reference.4: Failed to read schema document 'http://www.springframework.org/schema/context/spring-context.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>. ...

我还尝试将架构定义(即spring-context.xsd等)直接附加到类路径,但是没有成功。
spring-context.xsd
less src/main/resources/applicationContext.xml <?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd"> <context:annotation-config /> <!-- wegen '@PostConstruct' --> <!--<context:component-scan base-package="de.fraunhofer" /> --> ... </beans>
Spring命名空间处理程序使用文件/META-INF/spring.schemas和解析/META-INF/spring.handlers。由于具有这些名称的文件存在于不同的Spring jar中,因此之后可能仅其中一个保留在目标jar中maven-assembly-plugin。
/META-INF/spring.schemas
/META-INF/spring.handlers
也许你可以手动合并这些文件,然后以某种方式配置maven-assembly-plugin为使用此合并文件覆盖目标jar中的文件。
