从依赖罐类自动装配注解 [英] Auto-wiring annotations in classes from dependent jars

问题描述

我是比较新的Java，所以我希望这不是一个愚蠢的问题。

I'm relatively new to Java, so I hope this isn't a dumb question.

我在Eclipse Web项目，我试图部署到Tomcat。我有被编译成.jar文件，并部署到/ WEB-INF / lib目录在Eclipse两个因项目。

I have a Web project in Eclipse that I'm trying to deploy to Tomcat. I have two dependent projects in Eclipse which are being compiled into .jar files and deployed to the /WEB-INF/lib directory.

这是好的，但不幸的是，除非春季从.jar文件的类文件解压缩到/ WEB-INF / classes目录中不依赖扫描注释。

This is fine, but unfortunately Spring doesn't scan for annotations in dependencies unless the class files from the .jars are extracted into the /WEB-INF/classes directory.

有没有一种简单的方法来做到这一点的提取在制作的时候？我使用Maven。我写了暂时做到这一点（我开发在Windows上，部署在Ubuntu）

Is there an easy way to do this extraction at build time? I'm using Maven. I've written a batch file for the time being to do this (I'm developing on Windows, deploying on Ubuntu)

我有关于如何自动运行该服务器部署的问题，不过，我是不是做错了什么？当然，我不是这个问题搏斗唯一的一个。

I do have questions about how to automate this for server deployment, though, am I doing something wrong? Surely I'm not the only one to wrestle with this problem.

推荐答案

根据这个春天问题，
如果你在Eclipse中使用导出生成JAR文件...>的Java> JAR文件向导，然后你必须检查在添加目录条目复选框（默认情况下选中）为Spring的组件扫描来查找JAR文件的组件。

According to this Spring issue, if you're creating JAR files in Eclipse using the Export... > Java > JAR file wizard, then you have to check the Add directory entries checkbox (unchecked by default) for Spring's component scan to find components in the JAR files.
