为什么我的Web应用程序应用程序上下文无法加载我的jar属性文件？

标签： spring-mvc classloader spring-boot

这是我的设置/上下文。我有一个使用spring-boot 1.1.4的JAR项目，它使用Java配置加载属性文件：

@Configuration
@ComponentScan
@EnableAutoConfiguration
@PropertySource(name="appProps", value="classpath*:application-${spring.profiles.active}.properties")
public class DataJpaApplication {


@Autowired Environment env;


@Bean
//note, this PSPSHC is ours derived from the Spring one with specialized code.
public static org.springframework.context.support.PropertySourcesPlaceholderConfigurer propertySourcesPlaceholderConfigurer() {
    PropertySourcesPlaceHolderConfigurer encryptionPropertySourcesPlaceHolderConfigurer = new PropertySourcesPlaceHolderConfigurer();
    encryptionPropertySourcesPlaceHolderConfigurer
            .setIgnoreUnresolvablePlaceholders(true);
    return encryptionPropertySourcesPlaceHolderConfigurer;
}
}

这个jar可以单独使用单元测试。然后我尝试将它合并到一个Web应用程序（不使用spring-boot的spring mvc web app）中，使其成为maven依赖项并将其添加到上下文中：

<beans:bean id="jpaConfigBean"
    class="com.somepackage.DataJpaApplication" />

我有一个Web应用程序单元测试，它尝试加载Web应用程序的应用程序上下文，并且工作正常（包括从jar加载上下文和属性文件）。但是，当我将此Web应用程序部署到容器（tcServer）时，它会失败并显示以下内容：

Caused by: java.io.FileNotFoundException: Could not open ServletContext resource [/application-local.properties]

修改

关于上述错误的澄清。 Web应用程序正在加载其上下文并导入jar文件的上下文。正是这个jar项目通过@PropertySource加载application-local.properties。那么，这可能是围绕父/子上下文交互吗？

注意：否代码在哪里添加斜杠。

以下是我在网络应用程序中引导spring配置的方法：

<servlet>
<servlet-name>appServlet</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
  <param-name>contextConfigLocation</param-name>
  <param-value>classpath*:**/servlet-context.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>

我检查过以下几类：

  1. 确认maven生成的清单在war文件中有一个jar文件的类路径条目。
  2. 更改web.xml以使用/WEB-INF/servlet-context.xml（标准路径）
  3. 在JBoss中部署此Web应用程序而不是tc
  4. 将应用程序 - *。属性文件移动到另一个文件夹并引用该文件夹
  5. 将* .property文件复制到Web应用程序项目
  6. 确认WTP部署程序集实际上是引用maven
  7. 打开生成的war文件并确认jar文件中的文件位于预期位置。

    8. 以及其他一些没有成功的事情。

    我没有看到这个问题。请帮助找出错误/错误配置的位置。另外，如果您需要查看其他配置或文件以帮助调试此问题，请与我们联系。
