Spring类路径变量不起作用

Question

我正在尝试使用classpath 变量，但我总是得到FileNotFoundException。

<?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:p="http://www.springframework.org/schema/p"

       http://www.springframework.org/schema/data/jpa http://www.springframework.org/schema/data/jpa/spring-jpa.xsd">


    <tx:annotation-driven />
    <context:component-scan base-package="ar.com.conexia.salud.*" />

    <bean id="pdfGenerator" class="ar.com.conexia.generator.PdfGenerator">
<!--        <constructor-arg
            value="#{systemProperties['catalina.home']}/webapps/COMEI_Beneficiario/WEB-INF/classes/reports/" /> -->
        <constructor-arg value="classpath:/reports/" />
        <constructor-arg value="C://reports//" />
    </bean>

</beans>

如您所见，我尝试使用 catalina.home 变量作为替代方法来检查我的文件没有任何其他问题，这很好。

谢谢。

编辑：我将这些基本路径与文件名连接起来以打开文件。

试试这个 在xml文件中放

<context:component-scan base-package="com.your.package.name" />

并创建类

@Configuration
public class Config {
    @Bean
    public PdfGenerator sessionFactoryBean(){
        PdfGenerator pdfGen=new PdfGenerator("classpath:/reports/","C://reports//");
        return pdfGen;
    }
}
