切换到Java 1.8-Spring 4后无法打开ServletContext资源[/jdbc.properties]

Question

我有两个Spring项目,Backend和Frontend.后端的升级没有问题(Spring 4.1.2.RELEASE).虽然部署前端我有这个例外:

org.springframework.beans.factory.BeanDefinitionStoreException: Failed to process import candidates for configuration class [acn.spring.config.AppConfig]; nested exception is java.io.FileNotFoundException: Could not open ServletContext resource [/jdbc.properties]
    at org.springframework.context.annotation.ConfigurationClassParser.processImports(ConfigurationClassParser.java:489)
....
Caused by: 
java.io.FileNotFoundException: Could not open ServletContext resource [/jdbc.properties]

这是Frontend的WebAppInitializer:

@Configuration
public class WebAppInitializer extends AbstractAnnotationConfigDispatcherServletInitializer {

    @Override
    protected Class<?>[] getRootConfigClasses() {
        return new Class<?>[] { AppConfig.class };
    }
    .....

Appconfig位于后端项目中,如下所示:

@Import(DataConfig.class)
@Configuration
public class AppConfig {
   ...
}

缺少的属性文件在DataConfig中使用,在此处导入:

@PropertySource("jdbc.properties")
@Configuration
public class DataConfig {
   ...
}

为什么找不到属性文件？

编辑:后端的Jar结构:

• META-INF
  • MANIFEST.MF
  • 行家
• mySourcePackages结构
• jdbc.properties

前端的战争结构:

• META-INF
  • MANIFEST.MF
  • 行家
• 资源
• WEB-INF
  • 类
    • mySourcePackages结构
  • JSP
  • LIB
    • 所有的罐子包括backend.jar

告诉配置类您的属性在类路径中.否则,默认情况下它将在Servlet上下文中查找,因为它是一个Web上下文.

@PropertySource("classpath:jdbc.properties")
