2.1 在Eclipse中设置本地Maven
Maven选用的版本是3。我在本地装了一个,然后在Eclipse中设定了一下。
Maven的配置文件
<?xml version="1.0" encoding="UTF-8"?>
<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0 http://maven.apache.org/xsd/settings-1.0.0.xsd">
<localRepository>E:\GreenAPP\apache-maven-3.3.9\repo</localRepository>
<mirrors>
<mirror>
<id>alimaven</id>
<name>aliyun maven</name>
<url>http://maven.aliyun.com/nexus/content/groups/public/</url>

</mirrors>
<profiles>
<profile>

<properties>

</properties>
</profile>
</profiles>
</settings>
2.2 创建Maven项目
2.2.1 Step by step
直接上图了。
Step 1
Step 2
2.2.2 修正错误
有两个地方不大对,
1. jre的版本
2. 缺少了web.xml文件和web项目的文件夹。
修复过程如下:
1. 选中项目,右击,选择 properties,打开对话框。修改Java的版本。并且去掉Dynamic Web Module的勾。
2. 重新勾选Dynamic Web Module,选择3.0版本。点击 Further configuration available… ,打开对话框。
3. 输入文件夹,勾选 Generated web.xml deployment descriptor,点击OK。
4. 可以看见生成的web.xml文件和相应的文件夹。
2.3 编写POM
2.3.1 添加方法
在Maven的 仓库 中搜索需要添加的repository,选择版本,在详情页面中直接拖拽repository的信息到POM文件中就行了。每次保存POM文件,项目都会自动刷新jar包。
2.3.2 POM中需要加入的jar包:
- spring-webmvc : 4.3.13.RELEASE
- spring-jdbc: 4.3.13.RELEASE
- spring-aspects: 4.3.13.RELEASE
- spring-test: 4.3.13.RELEASE [test]
- mybatis : 3.4.5
- mybatis-spring : 1.3.1
- mybatis-generator-core : 1.3.5
- mysql-connector-java : 5.1.41
- c3p0 : 0.9.1
- jstl : 1.2
- servlet-api : 3.0
- junit : 4.12 [test]
这些是目前建立项目所需要的,随着项目的继续,再不断完善和补充POM文件。
2.4 POM文件

到目前为止,项目的基本环境就算是告一段落了。下面要进行的是框架的配置。
(不着急,慢慢来,搞细致,记牢固)
