从Java启动Spring应用程序的异常

Question

我能够使用Maven编译并启动我的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)在一个文件中组装所有jar时,我总是Exception在java执行期间得到一个:

java -cp target/test-jar-with-dependencies.jar:. de.fraunhofer.fkie.tet.vmware.manager.Test

我还尝试将模式定义(即spring-context.xsd等)直接附加到类路径,但没有任何成功.

less src/main/resources/applicationContext.xml

Answer 1

使用文件/META-INF/spring.schemas和解析Spring命名空间处理程序/META-INF/spring.handlers.因为具有这些名称的文件存在于不同的Spring jar中,所以可能只有其中一个保留在目标jar之后maven-assembly-plugin.

也许您可以手动合并这些文件,并以某种方式配置maven-assembly-plugin为使用此合并文件覆盖目标jar中的文件.

Answer 2

我怀疑您的spring配置文件缺少contextXML名称空间。应该将其添加到您的spring配置文件的根元素中，如下所示：

<?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-3.0.xsd
           http://www.springframework.org/schema/context
           http://www.springframework.org/schema/context/spring-context-3.0.xsd">

    <context:annotation-config />
    <context:component-scan base-package="com.abc.xyz" />

</beans>
