eclipse + maven搭建SSM框架

╰半夏微凉° 2023-09-24 09:05 78阅读 0赞

1)Windows 10 企业版

2)JDK 1.8.0\_131

3)Eclipse Java EE IDE for Web Developers? Version: Neon.3 Release (4.6.3)

4)Tomcat 8.5

maven的下载地址：http://maven.apache.org/download.cgi

![588810ff631d461cbffa3b3507a8ed7d.png][]

下载后解压放在d:\\Java路径下?

![2e94d44ecf2d2d638a67bf170dc34ae6.png][]

在环境变量中，新增系统变量名：MAVEN\_HOME，变量值：D:\\Java\\maven

在Path中追加：%MAVEN\_HOME%\\bin;

在命令行窗口中输入：mvn –v，如果看见下图则说明maven安装配置完毕

maven仓库默认位置在系统用户目录下的.m2目录中，类似下图

![ae079c4810cee5a52fe96d03f25351a6.png][]

因为众所周知的原因，直接访问maven公共仓库的速度比较慢，所以推荐使用阿里的maven仓库镜像。编辑setting.xml文件，在mirrors节点下，新增如下内容，这样从仓库中下载jar包速度上会快很多。

nexus-aliyun

Nexus aliyun

http://maven.aliyun.com/nexus/content/groups/public

设置eclipse自带maven整合工具，在Preferences中找到Maven节点，观察User Settings项的设置是否正确

![9c54ef1636052ec8ee2a3f206c73b903.png][]

点击Installations节点，添加maven runtime

![7dd98aae499c96d99e9a321512ae1aa9.png][]

问题描述：eclipse创建maven项目时，显示的JDK默认版本为1.5，实际使用的JDK为1.8，如何修改？

解决方案：找到本机maven仓库存放位置，比如：$\{user.home\}/.m2/路径，编辑settings.xml文件，在profiles节点下配置

1)选择Maven Project

![74b347f3b0bbf176f19b1407d9e1c042.png][]

2)点击Next，选择默认工作空间位置

![f6b232792c645d899e6ed22438167d6a.png][]

3)选择web类型

![7ab7d53877c9b956abd23cc4b906b4dc.png][]

4)填写GroupID、ArtifactID

![d111890ae68821c5da72f3feafd56f26.png][]

Group ID：相当于一个组织

Artifact ID：相当于这个组织下的一个具体项目

Packege：根据Group ID和Artifact ID生成一个默认的名称

5)创建出的maven项目如下图

6)问题描述：提示错误：

![32aa87eca626f75593dc03502ff00b41.png][]

在eclipse中设置Server为Tomcat，注意JRE设置为安装的JDK的jre

![a3f8b4de6cb38aa2cc87fb6e77b5479d.png][]

在工程上右键，查看工程属性，找到Java Build Path，添加Server Runtime为Tomcat

![5758c746a72cf6999b02d5bc642e8c82.png][]

![edd0ada074c642d98e59aae3f061797f.png][]

点击Finish后，项目工程变为下图

![7b6c61da8f6a0c66c96c792507a7e936.png][]

7)在项目上右键，查看项目信息

![a087382e380a0f585a3b4adfc3b02e4e.png][]

默认的Dynamic Web Module为2.3，使用Tomcat 8.5，需要修改为3.1

修改方法：

① maven工程所在目录下org.eclipse.wst.common.project.facet.core.xml

![b9d66fbf0cbbe0e5ab22623352bb70fc.png][]

编辑内容，如下所示

![复制代码][088c00dce96515d2234bc7cbc23c55af.gif]

![复制代码][Image 1]

② maven工程下的web.xml文件修改为

xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app\_3\_1.xsd"

version="3.1" metadata-complete="true">

③ pom.xml文件中修改build节点，添加如下内容

![复制代码][Image 1]

![复制代码][a776d3c04a5a2776370ba733363e52a4.gif]

org.apache.maven.plugins

maven-compiler-plugin

1.8

![复制代码][ce9a7e0bdf790a8256fd7cd3ba6b6d21.gif]

![复制代码][Image 1]

④ 修改后，在项目上右键，找到Maven属性下的Update Project，点击之

![ecbe73ffbc70f152978153b034290e79.png][]?

⑤ 选择该项目进行更新，如果怕不能强制更新，可以勾选Force Update of Snapshots/Releases

![0c3d76e4ea1fe190adf5e2f42a76e3b7.png][]

⑥ 点击OK后更新maven项目，再观察项目属性，Module已经变为3.1

![1ded3bf43492b999bf1e1403c3b1475d.png][]

修改pom.xml内容为：

保存后，可以看到相关jar包被下载至本地仓库?

因为服务端maven项目的标准结构有四个子包：src/main/java、src/main/resources、src/test/java、src/test/resources，这里缺少了src/test/resources，所以手动补上。

在项目中新建Source Folder

![aea46c0b4552b9df1e197e323db52484.png][]

创建src/test/resources目录后，工程如下图所示

![f55a5f5ddf8921a5ca738245bcc63278.png][]

右键查看项目属性，点击Deployment Assembly，移除test和target

![4a2de0fbfbfefefe9432ddf3a6eec4d3.png][]

移除后如下图
