IDEA建立Web項目

1.建立Project

1）File->New Project

2)選中Maven,點擊Next

3）輸入GroupId,ArtifactId,Version

4）設置工程名，位置等，點Finish。

5）工程主界面

6）刪除src文件夾和demo.iml,修改pom文件。

pom.xml內容以下

<?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/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>

    <groupId>com.company</groupId>
    <artifactId>demo</artifactId>
    <packaging>pom</packaging>
    <version>1.0.0</version>
    
    <properties>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    </properties>

    <distributionManagement>
        <repository>
            <id>nexus-releases</id>
            <url>http://localhost:8181/repository/maven-releases/</url>
        </repository>

        <snapshotRepository>
            <id>nexus-snapshot</id>
            <url>http://localhost:8181/repository/maven-snapshots/</url>
        </snapshotRepository>
    </distributionManagement>
</project>

注意事項：nexus-releases、nexus-snapshot對應着maven的settings.xml中server,若沒有配置則將distributionManagement標籤刪除

7）IDEA中maven配置（-Dmaven.multiModuleProjectDirectory=$M2_HOME）

 

2.建立module

1)選中demo工程，右鍵New,選中Module

2)選中maven,點Next

3)填寫ArtifactId,點擊Next

4)填寫Module name,點擊Finish。

5)重複步驟1-4，建立demo-data,demo-service,demo-web三個module，建立完成後如圖。

6)修改pom.xml

demo-base中pom.xml

demo-data中pom.xml

<?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/xsd/maven-4.0.0.xsd">
    <parent>
        <artifactId>demo</artifactId>
        <groupId>com.company</groupId>
        <version>1.0.0</version>
    </parent>
    <modelVersion>4.0.0</modelVersion>

    <artifactId>demo-data</artifactId>

    <dependencies>
        <dependency>
            <artifactId>demo-base</artifactId>

            <version>1.0.0</version>
        </dependency>
    </dependencies>
</project>

demo-service中pom.xml

<?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/xsd/maven-4.0.0.xsd">
    <parent>
        <artifactId>demo</artifactId>
        <groupId>com.company</groupId>
        <version>1.0.0</version>
    </parent>
    <modelVersion>4.0.0</modelVersion>

    <artifactId>demo-service</artifactId>

        <dependency>
            <artifactId>demo-data</artifactId>

            <version>1.0.0</version>
        </dependency>
    </dependencies>
</project>

demo-web中pom.xml

<?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/xsd/maven-4.0.0.xsd">

    <modelVersion>4.0.0</modelVersion>

    <artifactId>demo-web</artifactId>
    <packaging>war</packaging>

    <dependencies>
        <dependency>
            <groupId>com.company</groupId>
            <artifactId>demo-service</artifactId>
            <version>1.0.0</version>
        </dependency>
    </dependencies>
</project>

 

3.將demo-web改Web工程

在demo-web->src->main,右鍵new->Diretory

2)輸入webapp,點ok

3)在webapp繼續建立WEB-INF文件夾以及index.html,而後在WEB-INF下建立web.xml

結構圖以下

index.html

<!DOCTYPE html>
<html>
<head lang="en">
    <meta charset="UTF-8">
    <title></title>
</head>
<body>
    Hello,World!
</body>
</html>

web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://java.sun.com/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
                             http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
         version="3.0">

</web-app>

 

4.將web項目部署到tomcat並運行

1）點擊工程右上角

2）點"+"->tomcat Server->Local

3）配置tomcat

4)運行

運行結果：

5.補充-工程說明

1）各module說明

• demo-base:真個demo的基礎依賴包，也能夠公用。
• demo-data:數據層（即DAO），配置對應數據庫。
• demo-service:服務層，事務配置。
• demo-web:web層（即controller）。

項目依賴：demo-web=>demo-service=>demo-service=>demo-data=>demo-base

 

2）單一module工程結構說明

File=>Project Structure

• main/java：源碼目錄
• main/resources：資源文件目錄，能夠放對應配置，編譯時到classpath
• test/java：測試類目錄
