本篇文章主要介绍了maven多模块工程打包部署的方法步骤,小编觉得挺不错的,现在分享给大家,也给大家做个参考。一起跟随小编过来看看吧
一般maven多模块工程结构如下图,图中分为dao数据层和上层web层(当然还可以有service层),在进行多模块划分的时候,一般将dao层采用jar进行打包,web层进行war打包。在进行war包部署时,发现dao是以jar包形式存在于lib包目录下,如果在部署服务器上需要进行相关配置修改会比较麻烦。因此研究了下用maven进行合并打包的方法:

1.确保dao pom.xml中有以下配置

< include >**/*.properties</ include >
</ includes >
</ resource >
< resource >
< directory >${basedir}/src/main/resources</ directory >
</ resource >
</ resources >

2.在dao目录下执行:mvn clean install -Dmaven.test.skip=true,以生成jar包
3.在web工程pom.xml添加以下插件配置

上述插件表示将dao-1.0.jar解压至web工程的target/classes目录中(即工程编译源码目录)
4.运行web工程,即可发现dao相关配置文件及源码已合并过来。(注意,此时在默认的war包的lib中还会包含dao的jar)
若还需要对war工程进行jar打包部署,则在web工程pom.xml中添加jar打包插件即可

加入后,在web下重新执行mvn install命令,会在target/WEB-INF/lib目录下生成web.jar文件,jar中不包含properties和xml文件(去掉excludes,默认情况下会将所有文件进行打包)。
在上面情况下并没有将配置文件打包,因此需要将配置文件进行拷贝:

通过上面配置方式,则可将配置文件拷贝至target/WEB-INF/classes目录下
通过上述配置,对于web工程部署,还缺少所依赖的其他jar包,因此需要将jar包拷贝过来(同时去除依赖的dao):

通过以上步骤可在target目录看到web常规工程部署结构:
