使用Maven管理WEB專案套件

最近要來玩玩看Spring4的時候發現找不到下載點，因為Spring已經把Maven作為主要的提供方式了，
好吧，那你就只好學吧

1.準備軟體

Eclipse IDE for Java EE Developers下載 : http://maven.apache.org/
Maven 3.2.1 (Binary zip) 下載 : http://maven.apache.org/download.cgi
Maven解壓縮後我是放在D:\IDE\maven

2.修改Maven本地庫位置

開啟設定檔 D:\IDE\maven\apache-maven-3.2.1\conf\settings.xml
修改本地庫路徑

<localRepository>D:\IDE\maven\repository</localRepository>

3.設定Eclipse Maven環境

Windows -> Preferences -> Maven -> Installations

因為Eclipse原本好像就會自帶設定，所以要去修改使用我們剛剛修改的設定檔
切換到User Settings

這樣設定後，下載的程式庫就會存在我們指定的位置

4.新建Maven WebApp專案

這邊是用類似模板的方式新建專案

這樣就建立了一個Web專案，有錯是因為缺servlet-api，等下設定套件後就好了

最開始的設定檔長這樣

pom.xml

<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>
  <groupId>sam</groupId>
  <artifactId>testweb</artifactId>
  <packaging>war</packaging>
  <version>0.0.1-SNAPSHOT</version>
  <name>testweb Maven Webapp</name>
  <url>http://maven.apache.org</url>
  <dependencies>
    <dependency>
      <groupId>junit</groupId>
      <artifactId>junit</artifactId>
      <version>3.8.1</version>
      <scope>test</scope>
    </dependency>
  </dependencies>
  <build>
    <finalName>testweb</finalName>
  </build>
</project>

先補上servlet-api(放在dependencies標籤中間)，scope=provided表示說這套件只在編譯開發時期使用，匯出時不會包含

<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>javax.servlet-api</artifactId>
    <version>3.0.1</version>
    <scope>provided</scope>
</dependency>

加上後他會自動下載並編譯，專案的錯誤就不見了

再加上一些常用設定

定義常數

<properties>
        <spring.version>4.0.2.RELEASE</spring.version>
        <hibernate.version>4.3.4.Final</hibernate.version>
        <build.sourceEncoding>UTF-8</build.sourceEncoding>
</properties>

接下來設定套件就可以採用上邊的常數

<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-core</artifactId>
    <version>${spring.version}</version>
</dependency>

接下來定義編譯環境，這邊要改成JDK7

<build>
        <finalName>test</finalName>
        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-compiler-plugin</artifactId>
                <version>3.1</version>
                <configuration>
                    <source>1.7</source>
                    <target>1.7</target>
                </configuration>
            </plugin>
        </plugins>
    </build>

改完後會出現錯誤，主要是因為編譯版本不同，專案內模板是1.5

你可以自己去改Project Facets來符合你要的設定

或是讓它快速修正像下面結果也是一樣的

再來要改WebModule為3以上版的會有錯不能改，要繞一下方法

先把Dynamic勾選取消，再按確定返回

再開啟Project Facets設定，改成你要的版本並勾選(坑爹的這樣就可以!!搞我一天)

這樣子就變更好了

之後就跟寫一般Web差不多
