如何使用spring安全性访问根服务器中的文件

Question

我正在使用grails 3.1.1 我已经使用tomcat 8部署了war文件，并将我的所有图像文件存储到/app/Item/

这是我服务器中的文件夹结构。

/app/Item/<all my image>
/home
/root/apache-tomcat-8/
     /apache-tomcat-8/webapps
     /apache-tomcat-8/webapps/ROOT.war
     /apache-tomcat-8/bin
     /apache-tomcat-8/logs
     /apache-tomcat-8/work
     /apache-tomcat-8/temp
     /apache-tomcat-8/conf

现在我使用symlink访问/app/Item 所以我在/apache-tomcat-8/webapps/images创建了一个名为images的符号链接 因此，当我访问localhost:8080/images/100.JPG时，它将访问/app/Item/100.JPG

但是如果我重新运行我的tomcat，我会得到一些错误日志，因为我用images创建的文件夹symlink不在我的grails项目中。 喜欢这个..

现在我想知道如何在没有/app/Item/但我的grails应用程序中访问我的文件夹symlink？

我尝试在没有symlink或images的文件夹（快捷方式）的情况下进行部署

------------------这是symlink

然后我尝试read this并将此代码添加到我的server.xml

<Context docBase="/app/Item" path="/gambarku" />

然后再次启动。

我得到这个日志。

当我尝试使用symlink时，此日志相同。

我试图找到一些文档，我已经在文件夹WEB-INF/lib/mysql-connector-java-5.1.20.jar和build.gradle中检查runtime 'mysql:mysql-connector-java:5.1.20'

Answer 1

def image = new File('/app/Item/image1.jpg')

Answer 2

这是一个很长的镜头，但可能会解决您的问题，它与您最初的配置非常相似，只需添加 allowLinking =“true”：

• 在 / app / Item 和 / apache-tomcat-8 / webapps / images
之间创建符号链接

• 将此添加到您的配置

        <Context docBase="/app/Item" path="/images" allowLinking="true"/>
