/ tmp / tomcat-docbase总是使用Spring Boot JAR创建（但不是WAR） [英] /tmp/tomcat-docbase is always created with a Spring Boot JAR (but not a WAR)

问题描述

从STS我正在创建一个标准的Spring Boot 1.5.2'Web'项目。如果运行此应用程序，则会创建两个目录 - 正常的base目录和tomcat-docbase目录

From STS I'm creating a standard Spring Boot 1.5.2 'Web' project. If you run this application you get two directories created - the normal 'base' directory and a 'tomcat-docbase' directory

. . .  4096 Mar 29 10:00 tomcat.2743776473678691880.8080
. . .  4096 Mar 29 10:00 tomcat-docbase.76291847886629412.8080

如果我将此项目更改为WAR项目我只获取'base'目录

If I change this project to a WAR project I get only the 'base' directory

. . .   4096 Mar 29 10:06 tomcat.3131223012454570991.8080

使用

It's easy to override the default base directory using

 server.tomcat.basedir=.

但是这对tomcat-docbase没有影响。可以通过编程方式覆盖tomcat-docbase，但看起来像是一个黑客。

however this has no effect on tomcat-docbase. It is possible to override tomcat-docbase programmatically but seems like a hack.

有人认为这是一个错误吗？

Does anyone think this is a bug?

谢谢

推荐答案

解决方案：
在您的项目下创建一个文件夹名称 public ，与您的文件夹在同一文件夹中JAR。

Solution: create a folder name as public under your project, in the same folder with your JAR.

原因：来自springboot代码的
，没有docbase文件夹的配置。
，但您可以在项目文件夹名称中创建一个公共根文件夹，如 public ， static 或 src / main / webapp ，然后springboot永远不会再为你创建临时tomcat-docbase文件夹。

Reason: from the springboot code, there is no configuration for docbase folder. but you can create a common root folder in you project folder name as public, static or src/main/webapp, then the springboot will never create temp tomcat-docbase folder for you again.

private static final String[] COMMON_DOC_ROOTS = { "src/main/webapp", "public", "static" }
...
public final File getValidDirectory() {
    File file = this.directory;
    file = (file != null ? file : getWarFileDocumentRoot());
    file = (file != null ? file : getExplodedWarFileDocumentRoot());
    file = (file != null ? file : getCommonDocumentRoot());
    if (file == null && this.logger.isDebugEnabled()) {
        logNoDocumentRoots();
    }
    else if (this.logger.isDebugEnabled()) {
        this.logger.debug("Document root: " + file);
    }
    return file;
}
...
private File getCommonDocumentRoot() {
    for (String commonDocRoot : COMMON_DOC_ROOTS) {
        File root = new File(commonDocRoot);
        if (root.exists() && root.isDirectory()) {
            return root.getAbsoluteFile();
        }
    }
    return null;
}
