spring boot FileNotFoundException: Could not open ServletContext resource [/WEB-INF/main-servlet.xml]
提问by mangusbrother
I am running a spring boot application with the following application class:
我正在运行具有以下应用程序类的 Spring Boot 应用程序：
@EnableAutoConfiguration
@Configuration
public class FakeAppBooter extends SpringBootServletInitializer{
public static void main(String args[]) {

}
}
@Bean

}
My layout is as follows
我的布局如下
- src/main/java
- boot/FakeAppBooter.java
- src/main/webapp
- WEB-INF
- main-servlet.xml
- WEB-INF
- src/main/resources
- 源代码/主/Java
- 引导/FakeAppBooter.java
- 源代码/主/网络应用程序
- 网络信息
- 主servlet.xml
- 网络信息
- 源代码/主要/资源
I have tried using above layout, as well as moving the WEB-INF folder to the resources folder
我已经尝试使用上面的布局，以及将 WEB-INF 文件夹移动到资源文件夹
If I package the project as war file with WEB-INF under weabpp, I get the WEB-INF folder in the root of the war file, however on startup I get:
如果我在 webpp 下使用 WEB-INF 将项目打包为 war 文件，我会在 war 文件的根目录中获取 WEB-INF 文件夹，但是在启动时我得到：

If I move the WEB-INF folder to the resources folder and package as a jar file, I get no error on startup, however I still get the FileNotFoundException when I try to load a webpage, as follows:
如果我将 WEB-INF 文件夹移动到资源文件夹并打包为 jar 文件，我在启动时不会出错，但是当我尝试加载网页时仍然出现 FileNotFoundException，如下所示：

回答by Bohuslav Burghardt
Unless you are running your application as WAR, the src/main/webappfolder won't be included in the output as stated in the documentation:
除非您将应用程序作为 WAR 运行，否则该src/main/webapp文件夹将不会包含在文档中所述的输出中：
Do not use the
src/main/webappfolder if your application will be packaged as a jar. Although this folder is a common standard, it will only work with war packaging and it will be silently ignored by most build tools if you generate a jar.
src/main/webapp如果您的应用程序将被打包为 jar，请不要使用该文件夹。虽然这个文件夹是一个通用的标准，但它只适用于 war 打包，如果你生成一个 jar，它会被大多数构建工具默默地忽略。
So that may be your problem.
所以这可能是你的问题。
To fix it try to set config location explicitly for the main servlet:
要修复它，请尝试为主 servlet 显式设置配置位置：
servlet.addInitParameter("contextConfigLocation", "classpath:main-servlet.xml");
and place the main-servlet.xmlfile in src/main/resources.
并将main-servlet.xml文件放在src/main/resources.
Hope this helps.
希望这可以帮助。
