maven建立多模組web專案
實現步驟
建立專案目錄
進入“工作空間”目錄,建立名為tradework 的資料夾,切換至控制檯,進入該資料夾。
配置模組
生成各個模組
該步驟會依次生成專案的各個模組,但是生成的模組並沒有 建立依賴,只是最簡單的並且符合maven 要求的專案結構的模組,關於什麼是 maven 的標準專案結構,可以參考 maven 官方文件,或者《 maven 權威指南》。
#core 模組建立
mvn archetype:create -DgroupId=uppower.trade -DartifactId=trade-core
#client 模組建立
mvn archetype:create -DgroupId=uppower.trade -DartifactId=trade-client
mvn archetype:create -DgroupId=uppower.trade -DartifactId=trade-server -DpackageName=uppower.trade -DarchetypeArtifactId=maven-archetype-webapp
配置專案模組
在tradework 根目錄下新建一個 pom.xml 配置檔案,加入如下內容:
<?xml version="1.0" encoding="UTF-8"?> <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>uppower</groupId> <artifactId>parent</artifactId> <version>1.0.1</version> </parent> <groupId>uppower.trade</groupId> <artifactId>trade-parent</artifactId> <packaging>pom</packaging> <version>1.0-SNAPSHOT</version> <name>trade-parent</name> <url>http://maven.apache.org</url> <modules> <module>trade-client</module> <module>trade-core</module> <module>trade-server</module> </modules> </project>
這裡需要注意的是modules 節點,配置了上一步生成的四個模組。這樣就組織起了其依賴關係。
生成好各個模組之後在tradework 根目錄下會生成三個目錄,每個目錄下都會有一個 pom.xml 的配置檔案,將這些配置檔案開啟。新增 parent 節點,client模組內容如下:
<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>uppower.trade</groupId> <artifactId>trade-parent</artifactId> <version>1.0-SNAPSHOT</version> </parent> <groupId>uppower.trade</groupId> <artifactId>trade-client</artifactId> <packaging>jar</packaging> <version>1.0-SNAPSHOT</version> <name>trade-client</name> <url>http://maven.apache.org</url> <dependencies> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> </dependency> </dependencies> </project>
同理,針對core模組:
<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>uppower.trade</groupId> <artifactId>trade-parent</artifactId> <version>1.0-SNAPSHOT</version> </parent> <groupId>uppower.trade</groupId> <artifactId>trade-core</artifactId> <packaging>jar</packaging> <version>1.0-SNAPSHOT</version> <name>trade-core</name> <url>http://maven.apache.org</url> <dependencies> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> </dependency> <dependency> <groupId>uppower.trade</groupId> <artifactId>trade-client</artifactId> <version>1.0-SNAPSHOT</version> </dependency> </dependencies> </project>
同理,針對server模組,其中值得注意的是,server模組是打包為war包:
<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>uppower.trade</groupId> <artifactId>trade-parent</artifactId> <version>1.0-SNAPSHOT</version> </parent> <groupId>uppower.trade</groupId> <artifactId>trade-server</artifactId> <packaging>war</packaging> <version>1.0-SNAPSHOT</version> <name>trade-server Maven Webapp</name> <url>http://maven.apache.org</url> <dependencies> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> </dependency> </dependencies> </project>
配置依賴
進入tradework 根目錄,在 pom.xml 檔案中加入 dependencies 節點,加入如下內容:
<dependencyManagement> <dependencies> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.7</version> <scope>test</scope> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring</artifactId> <version>2.0.7</version> </dependency> <dependency> <groupId>org.apache.ibatis</groupId> <artifactId>ibatis-sqlmap</artifactId> <version>2.3.0</version> </dependency> <dependency> <groupId>com.ibatis</groupId> <artifactId>ibatis-dao</artifactId> <version>2.1.0.565</version> </dependency> <dependency> <groupId>commons-dbcp</groupId> <artifactId>commons-dbcp</artifactId> <version>1.2.2</version> </dependency> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>5.1.12</version> </dependency> <dependency> <groupId>javax.servlet</groupId> <artifactId>servlet-api</artifactId> <version>2.5</version> </dependency> <dependency> <groupId>apache-log4j</groupId> <artifactId>log4j</artifactId> <version>1.2.15</version> </dependency> </dependencies> </dependencyManagement>
進入tradework 根目錄下,trade-server目錄,在 pom.xml 檔案中加入 dependencies 節點,內容如下:
<dependencies> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring</artifactId> </dependency> <dependency> <groupId>org.apache.ibatis</groupId> <artifactId>ibatis-sqlmap</artifactId> </dependency> <dependency> <groupId>com.ibatis</groupId> <artifactId>ibatis-dao</artifactId> </dependency> <dependency> <groupId>commons-dbcp</groupId> <artifactId>commons-dbcp</artifactId> </dependency> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> </dependency> <dependency> <groupId>apache-log4j</groupId> <artifactId>log4j</artifactId> </dependency> <dependency> <groupId>javax.servlet</groupId> <artifactId>servlet-api</artifactId> </dependency> <dependency> <groupId>uppower.trade</groupId> <artifactId>trade-client</artifactId> <version>1.0-SNAPSHOT</version> </dependency> <dependency> <groupId>uppower.trade</groupId> <artifactId>trade-core</artifactId> <version>1.0-SNAPSHOT</version> </dependency> </dependencies> <build> <finalName>trade-server</finalName> </build>
修改配置完成之後,在tradework目錄下,執行:
mvn eclipse:eclipse
生成 Eclipse 專案檔案及包引用定義,注意,需確保定義Classpath Variables: M2_REPO,指向本地maven類庫目錄。
開啟Eclipse ,匯入工程即可。
