linux 环境下 用maven 创建项目（子项目分层创建）springMVC项目
来源：互联网 发布：林小宅扒皮 知乎 编辑：程序博客网 时间：2024/06/10 09:41
可以看下我的GITHUB的项目结构：https://github.com/cwtree/demoall
项目的整体目录结构
demo(demo.biz，demo.common，demo.config，demo.data，demo.web)
demo是最外层的目录，后面各个子项目分别负责业务层，工具、常用辅助类层，配置层，数据层，web层
本文章采用maven构建项目，maven的目录结构
src/main/java
src/test/java
src/main/resources
1、首先通过eclipse工具创建一个web project，这样会省去很多麻烦
将以下pom.xml文件放到demo.web下
web
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd"> <modelVersion>4.0.0</modelVersion> <parent> <groupId>demo.all</groupId> <version>0.1</version> <artifactId>demo.all</artifactId> <relativePath>../pom.xml</relativePath></parent> <groupId>demo.web</groupId> <artifactId>demo.web</artifactId> <packaging>war</packaging> <version>0.1</version> <name>demo.web</name><dependencies><dependency> <groupId>demo.common</groupId> <artifactId>demo.common</artifactId> <version>${pom.version}</version></dependency><dependency> <groupId>demo.biz</groupId> <artifactId>demo.biz</artifactId> <version>${pom.version}</version></dependency><dependency> <groupId>demo.config</groupId> <artifactId>demo.config</artifactId> <version>${pom.version}</version></dependency><dependency> <groupId>demo.data</groupId> <artifactId>demo.data</artifactId> <version>${pom.version}</version></dependency></dependencies> <build><resources> <resource> <directory>src/main/java</directory> <includes> <include>**/*.xml</include> <include>**/*.properties</include> </includes> </resource> <resource> <directory>src/main/resources</directory> <includes> <include>**/*.xml</include> <include>**/*.properties</include> </includes> </resource> </resources><finalName>demo.web-${pom.version}</finalName> </build></project>2、依次手动创建其余项目，手动建立MAVEN目录结构并创建pom.xml文件biz

下面在demo目录下执行如下命令：
mvn eclipse:eclipse -Dwtpversion=2.0 -DdownloadSources=true -DdownloadJavadocs=true

mvn clean install -Dmaven.test.skip
出现如下错误：

刚才，我们的WEB项目是通过eclipse创建的，而maven默认构建web项目时，
maven的web项目默认的webroot是在src\main\webapp。如果在此目录下找不到web.xml就抛出以上的异常。
我们将WEB-INF的父目录拷贝到src/main下面，再次执行mvn clean install命令成功

执行完如上命令，如果没有错误，则可以看见完整的项目结构了，这是从eclipse里面import这些项目，就一目了然了
