java - 导出的 jar 文件无法识别 SqlMapConfig.xml

Question

我想使用 Eclipse 导出功能导出我的 Java 项目。我的项目包含许多 Spring 库。我右键单击项目/导出/JAR 文件，选择项目，检查项目的所有内容，指定主类。当我使用参数运行它时，会发生错误。如何解决？

更新: 我尝试将其导出为 Runnable JAR 文件。它显示以下错误。 (抱歉，出于安全原因，我无法发布完整的错误日志)

        <constructor-arg>

        </constructor-arg>
    </bean>
</beans>

然后我加载它

String contextPath = "classpath:spring.xml";

BeanFactory context = 
    (BeanFactory) new FileSystemXmlApplicationContext(contextPath);

假设 Jar 中有 SqlMapConfig.xml，例如位置:

/res/ibatis/SqlMapConfig.xml

您应该在 spring.xml 文件中引用它，如下所示:

<bean id="sqlMapClient" class="org.springframework.orm.ibatis.SqlMapClientFactoryBean">
    <property name="configLocation" value="classpath:/res/ibatis/SqlMapConfig.xml"/>
    <property name="dataSource" ref="yourDataSource"/>
</bean>

(注意类路径:标记)
