Create a web version of MAVEN Engineering in Eclipse and learn more about the configuration settings issues for scope in Pom.xml

1. Create a web version of MAVEN project in Eclipse:

A, like creating a Java version of the MAVEN project, first select a simple project (skip the Classic mode), then fill in the coordinates (do not know the previous blog post), in the packaging method to select the war package, then click Finish.

b, you can see, in the new javaproject03 project, only the WebApp directory, and the actual content does not. Here we have to do the setup every time we create a new one. Settings are as follows:

Note: The mouse stops on the project you built, right-click to enter Properties---Project Facets, you can find the Dynamic Web Module is checked, uncheck the Apply button, then click the check box, and a hyperlink will be displayed directly below.

C, click the hyperlink, set the desired directory on Content directory, and tick the box that automatically generates the Web. XML deployment Descriptor.

D. After clicking on the app, the required content is displayed on the WebApp.

2, to further understand the scope of the Pom.xml configuration settings issues, easy to identify in eclipse.

Note: In the Pom.xml file, type:

<dependencies>
<dependency>
<groupId>log4j</groupId>
<artifactId>log4j</artifactId>
<version>1.2.17</version>
<scope>compile</scope>
</dependency>
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>3.8.1</version>
<scope>test</scope>
</dependency>
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>servlet-api</artifactId>
<version>2.5</version>
<scope>provided</scope>
</dependency>
</dependencies>

This is the location and name of MAVEN's coordinates locator jar package to log4j, its relative position and name is Repmaven\log4j\log4j-1.2.17.jar. After the WebApp directory (equivalent to the Webcontext directory) to create a newfile.jsp, and then run the right-click running as---run on server, after the run stopped, in the deployment project Lib package only log4j-1.2. 17.jar.

(Note that test and provided dependencies are not involved in packaging and deployment, compile is involved in packaging and deployment, and the default scope is compile.) ）
