eclipse+maven搭建ssm

曾经终败给现在 2022-05-09 08:20 286阅读 0赞

1）Windows 7 旗舰版

2）JDK 1.8.0\_131

3）Eclipse Java EE IDE for Web Developers Version: Neon.3 Release (4.7.3)

4）Tomcat 8.5

# 1、下载maven，配置maven环境变量。 #

maven的下载地址：[http://maven.apache.org/download.cgi][http_maven.apache.org_download.cgi]

解压后放在D盘最好，因为我C盘安装的固态，所以我放在C盘了

![70][]

配置maven环境变量，

在环境变量中，新增系统变量名：MAVEN\_HOME，变量值：C:\\apache-maven-3.5.3C:\\apache-maven-3.5.3

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

# 2、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 #

![70 2][]

点击Installations节点，添加maven runtime

![70 3][]

我的已经配置过了。所以显示名字重复错误。

# 3、创建maven项目， #

创建出的maven项目如下图

![70 7][]

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

![70 8][]

添加tomcat

![70 9][]

![70 10][]

![70 11][]

在项目上右键，查看项目信息

![70 12][]

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

![70 13][]

将下图的2.3改成3.1

② maven工程下的web.xml文件修改为

<?xml version="1.0" encoding="UTF-8"?>
    <web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
           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">
    </web-app>

③ pom.xml文件中修改build节点，添加如下内容

<plugins>
           <plugin>
                  <groupId>org.apache.maven.plugins</groupId>
                  <artifactId>maven-compiler-plugin</artifactId>
                  <configuration>
                         <source>1.8</source>
                         <target>1.8</target>
                  </configuration>
           </plugin>
    </plugins>

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

![438252-20170630083518711-1838871782.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

![438252-20170630083531743-1343327502.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

# 5、完善项目结构 #

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

创建src/test/resources目录后，工程如下图所示
