自动连接从依赖罐的类中的注释 [英] Auto-wiring annotations in classes from dependent jars

问题描述

我对Java很新，所以我希望这不是一个愚蠢的问题。

我在Eclipse中有一个Web项目，我试图部署到Tomcat。我在Eclipse中有两个依赖项目，它们被编译成.jar文件并被部署到/ WEB-INF / lib目录。

这很好，但不幸的是Spring不除非来自.jars的类文件被提取到/ WEB-INF / classes目录中，否则不会扫描依赖关系的注释。

有没有办法做到这一点在构建时提取？我正在使用Maven。我暂时写了一个批处理文件（我在Windows上开发，在Ubuntu上部署）

我对如何自动化这个问题有疑问对于服务器部署，但是我做错了什么？

解决方案

根据这个 Spring问题，
如果您使用导出...> Java在Eclipse中创建JAR文件> JAR文件向导，那么您必须检查Spring组件扫描的添加目录条目复选框（未选中），以查找JAR文件中的组件。

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

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.

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.

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)

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.

解决方案

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.
