一、MAVEN下载安装


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

技术图片

解压之后路径 D:\java\apache-maven-3.6.2;
新增系统变量【MAVEN_HOME】,变量名替换成自己本地解压路径

技术图片

系统变量【Path】追加值:%MAVEN_HOME%\bin

技术图片

运行cmd,输入mvn –version或者mvn –v;如果看见下图则说明maven安装配置完毕

技术图片

本地仓储配置文件:D:\java\apache-maven-3.6.2\conf\settings.xml
在maven目录下创建本地存储文件夹repository,设置本地存储路径 D:\java\apache-maven-3.6.2\repository

<localRepository>D:\java\apache-maven-3.6.2\repository</localRepository>

直接访问maven<localRepository>D:\java\apache-maven-3.6.2\repository</localRepository>公共仓库的速度比较慢,所以推荐使用阿里的maven仓库镜像,在mirrors节点下,新增如下内容

<mirror>
          <id>aliyun</id>
          <name>aliyun</name>
          <url>http://maven.aliyun.com/nexus/content/groups/public/</url>
          <mirrorOf>central</mirrorOf>
        </mirror>

设置默认jdk,在profiles节点下,新增如下内容(可以省略,在pom.xml配置也行)

<profile>
        <id>nexus</id>
        <repositories>
            <repository>
                <id>central</id>
                <url>http://repo.maven.apache.org/maven2</url>
                <snapshots>
                    <enabled>false</enabled>
                </snapshots>
            </repository>
            <repository>
                <id>ansj-repo</id>
                <name>ansj Repository</name>
                <url>http://maven.nlpcn.org/</url>
                <snapshots>
                    <enabled>false</enabled>
                </snapshots>
            </repository>
        </repositories>
    </profile>

二、MAVEN配置


Maven项目目录结构
|----src
| |----main
| | |----java —— java文件
| | |----resource ——资源文件
| | |----webapp ——jsp/html/css/image/js文件
| |----test
| | |----java ——测试java文件
| | |----resource ——资源文件
|----target ——项目输出位置
|----pom.xml ——maven项目的标志


eclipse设置Maven
在Window----Preferences中找到Maven节点----User Setting,设置如下图:

技术图片

点击Installations节点,添加maven runtime如下图所示

技术图片

三、eclipse创建Maven工程


点击File----New----Maven Project(默认有的话)或者File----New----Other,选择maven文件夹,点击Maven Project如下图所示

技术图片

点击Next,选择默认工作空间位置,选择web类型,再点击Next

技术图片

技术图片

填写GroupID、ArtifactID,点击Finish完成maven项目web工程的创建
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

技术图片

四、配置的修改


在项目上右键,查看项目信息,默认的Dynamic Web Module为2.3,使用Tomcat 8.5,需要修改为3.1

技术图片

(1).找到maven工程所在目录下org.eclipse.wst.common.project.facet.core.xml此文件

技术图片

技术图片

(2).maven工程下的web.xml文件替换为

<?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).在项目上右键,找到Maven属性下的Update Project

技术图片

(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,更新完毕再一次查看Dynamic Web Module是否为3.1

技术图片

右键项目--Properties--Deployment Assembly,移除target

技术图片

五、案例测试


目录结构

技术图片

  1. Pom.xml再添加如下内容
<properties>
        <srping.version>4.0.2.RELEASE</srping.version>
        <mybatis.version>3.2.8</mybatis.version>
        <slf4j.version>1.7.12</slf4j.version>

        logger.info("查询完毕,返回页面");

}

10.web.xml添加如下配置

<!-- spring容器配置 -->
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <!-- 注意,spring加载配置文件 -->
        <param-value>
            classpath:spring-mybatis.xml
        </param-value>
    </context-param>
    <!-- spring容器监听器 -->
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>

    <!--springMVC的核心分发器 -->
    <servlet>
        <servlet-name>spring-mvc</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <!-- 指定Spring的配置文件 -->
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath:spring-mvc.xml</param-value>
        </init-param>
        <!-- 启动加载一次 -->
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>spring-mvc</servlet-name>
        <!-- 此处可以可以配置成*.do 适配Struts的习惯 -->
        <url-pattern>/</url-pattern>
    </servlet-mapping>

    <!-- 防止Spring内存溢出监听器 -->
    <listener>
        <listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class>
    </listener>

    <!-- 解决工程编码过滤器 -->

11.jsp/user.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>User</title>
</head>
<body>
    <h1>${requestScope.user}</h1>
</body>

12.建数据库test,然后在创建表

CREATE TABLE `user` (
  `userid` INT(11) NOT NULL AUTO_INCREMENT,
  `username` VARCHAR(255) DEFAULT NULL,
  `password` VARCHAR(255) DEFAULT NULL,
  `email` VARCHAR(255) DEFAULT NULL,
  `phone` VARCHAR(255) DEFAULT NULL,
  `status` VARCHAR(255) NOT NULL DEFAULT ‘0‘,
  `code` VARCHAR(255) DEFAULT NULL,
  PRIMARY KEY (`userid`)
) ENGINE=INNODB AUTO_INCREMENT=16 DEFAULT CHARSET=utf8;

13.项目部署

配置 Tomcat 访问权限,tomcat中tomcat-user.xml的配置(tomcat根目录/conf/tomcat-users.xml)

<role rolename="manager-gui"/> 
<role rolename="manager-script"/>
<role rolename="manager-jmx"/>
<role rolename="manager-status"/>
<user password="123456" username="root"
roles="manager-gui,manager-script,manager-jmx,manager-status" />

双击 tomcat 解压包中 bin 目录下的 startup.bat 命令进行启动Tomcat服务器。在浏览器地址来中进行访问http://127.0.0.1:8080/manager/

技术图片

输入用户名root,密码123456进行登录,如果顺利则请进入下一步。

技术图片

配置maven的setting.xml
在 conf/setting.xml 文件中的标签 <servers> 添加如下内容

 <server>
       <!--通过标签名字让 maven 去关联我们的 Tomcat 服务器--> 
        <id>tomcat8</id>
        <!--username 和 password 一定要和 tomcat 中的 tomcat_user.xml 中一致-->
        <username>root</username>
        <password>123456</password>
    </server>

在 pom.xml 文件的plugins子节点中添加如下内容

<plugin>
                <groupId>org.apache.tomcat.maven</groupId>
                <artifactId>tomcat7-maven-plugin</artifactId>
                <version>2.2</version>
                <configuration>
                    <url>http://127.0.0.1:8080/manager/text</url>
                    <!--关联id-->
                    <server>tomcat8</server>
                    <username>root</username>
                    <password>123456</password>
                    <!--访问的路径(项目名)-->
                    <path>/ssm01</path>
                    <update>true</update>
                </configuration>
            </plugin>

先运行Tomcat目录下/bin/startup.bat
然后右击项目Run As–Maven build,在Goals中输入:clean install tomcat7:redeploy

访问如下图表示配置成功
技术图片

附:maven命令
执行命令
1)Run as → clean install
2)Run as → tomcat7:deploy 注:第1次部署执行
3)Run as → tomcat7:redeploy 注:第2次或以后需要重新发布执行
4)Run as → tomcat7:run 注:部署到 tomcat 中启动

在此过程中遇到的错误

技术图片

启动tomcat,在进行编译构建

用Mybatis去操作底层数据库的时候,需要用到xml配置文件,一般我们是把配置文件和dao放置在同一层目录。操作maven项目的时候,我们可能会遇到无法读取到dao对应的mapper.xml文件。在pom.xml的build节点中添加如下内容

<resources>
            <resource>
                <directory>src/main/resources</directory>
                <includes>
                    <include>**/*.properties</include>
                    <include>**/*.xml</include>
                </includes>
            </resource>
            <resource>
                <directory>src/main/java</directory>
                <includes>
                    <include>**/*.properties</include>
                    <include>**/*.xml</include>
                </includes>
            </resource>
</resources>
或者
<plugin>  
            <groupId>org.codehaus.mojo</groupId>  
            <artifactId>build-helper-maven-plugin</artifactId>  
            <version>1.8</version>  
            <executions>

                    <goals>  
                        <goal>add-resource</goal>  
                    </goals>  
                    <configuration>  
                        <resources>  
                            <resource>  
                                <directory>src/main/java</directory>  
                                <includes>  
                                    <include>**/*.xml</include>  
                                </includes>  
                            </resource>  
                        </resources>

                </execution>  
            </executions>  
</plugin>

                        </goals>
                        <configuration>
                            <resources>
