把上面代码复制到pom.xml里的标签内如下:
<?xml version="1.0" encoding="UTF-8"?>
<!-- 头信息
1.xmlns 命名空间,类似包名,因为xml的标签可自定义,需要命名空间来
2.xmlns:xsi xml遵循的标签规范
3.xsi:schemaLocation 用来定义xmlschema的地址,也就是xml书写时需要遵循的语法
-->
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
<!-- maven的基本信息
1.modelVersion 声明项目描述符遵循哪一个POM模型版本。模型本身的版本很少改变,虽然如此,但它仍然是必不可少的,这是为了当Maven引入了新的特性或者其他模型变更的时候,确保稳定性。
2.groupId 公司或者组织的唯一标志,并且配置时生成的路径也是由此生成,
3.如com.winner.trade,maven会将该项目打成的jar包放本地路径:/com/winner/trade
4.artifactId 本项目的唯一ID,一个groupId下面可能多个项目,就是靠artifactId来区分的
5.version 本项目目前所处的版本号
6.packaging 打包类型,可取值:pom , jar , maven-plugin , ejb , war , ear , rar , par等等
7.name 项目的名称, Maven产生的文档用,可省略
8.url 项目主页的URL, Maven产生的文档用 ,可省略
-->
<modelVersion>4.0.0</modelVersion>
<groupId>com.mycrm.maven</groupId>
<artifactId>my-crm-web</artifactId>
<version>1.0-SNAPSHOT</version>
<packaging>war</packaging>
<name>my-crm-web Maven Webapp</name>
<!-- FIXME change it to the project's website -->
<url>http://www.example.com</url>
<properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
<maven.compiler.source>1.7</maven.compiler.source>
<maven.compiler.target>1.7</maven.compiler.target>
</properties>
<!-- 主要用于POM文件的复用和依赖。依赖关系列表.描述了项目相关的所有依赖。 这些依赖组成了项目构建过程中的一个个环节。它们自动从项目定义的仓库中下载。
1.groupId 依赖项的组织名
2.artifactId 依赖项的子项目名
3.version 依赖项的版本
4.type 依赖类型一般省略,默认类型是jar,其他还有jar,war,ejb-client和test-jar
5.scope 依赖项的适用范围 ,包括compile,provided,runtime,test,system,exclusions [^1]
6.optional 可选依赖,如果你在项目B中把C依赖声明为可选,你就需要在依赖于B的项目(例如项目A)中显式的引用对C的依赖。
7.exclusions 排除项目中的依赖冲突时使用,不依赖该项目
scope 依赖项的适用范围:
1.compile,缺省值,适用于所有阶段,会随着项目一起发布。
2.provided,类似compile,期望JDK、容器或使用者会提供这个依赖。如servlet.jar。
3.runtime,只在运行时使用,如JDBC驱动,适用运行和测试阶段。
4.test,只在测试时使用,用于编译和运行测试代码。不会随项目发布。
5.system,类似provided,需要显式提供包含依赖的jar,Maven不会在Repository中查找它。
6.optional: 当项目自身被依赖时,标注依赖是否传递。用于连续依赖时使用

5.添加静态页面: 在tomocat上web项目结构如下: 因为web应用根目录下的内容都是不安全的,外界可以通过url直接访问,所以,一般为了数据的安全,都会把页面放在WEB-INF下,因为WEB-INF目录下的资源是受保护的。所以静态页面资源放置位置如下: 6.编写首页和登录页面: 用户控制器(UserController):
package com.mycrm.maven.settings.web.controller;
import com.mycrm.maven.commons.domain.ReturnObject;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpSession;
import java.util.HashMap;
import java.util.Map;
@Controller
@RequestMapping("/settings/power/user/")
public class UserController {
/**
* 登录页面
* @return
*/
@RequestMapping("login")
public String login(){
return "settings/power/user/login";
}

成功如图:
二,MyBatis逆向工程根据数据库生成model
在my-crm-web项目下的同级目录下创建maven工程 1.创建项目
生成项目如下: 在pom.xml添加myBatis逆向工程插件
<build>
<plugins>
<!--myBatis逆向工程插件-->
<plugin>
<groupId>org.mybatis.generator</groupId>
<artifactId>mybatis-generator-maven-plugin</artifactId>
<version>1.3.2</version>
<configuration>
<verbose>true</verbose>
<overwrite>true</overwrite>
</configuration>
</plugin>
</plugins>
</build>
添加后pom.xml如下:
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId>com.mycrm.maven</groupId>
<artifactId>crm-mybatis-generator</artifactId>
<version>1.0-SNAPSHOT</version>
<build>
<plugins>
<!--myBatis逆向工程插件-->
<plugin>
<groupId>org.mybatis.generator</groupId>
<artifactId>mybatis-generator-maven-plugin</artifactId>
<version>1.3.2</version>
<configuration>
<verbose>true</verbose>
<overwrite>true</overwrite>
</configuration>
</plugin>
</plugins>
</build>
</project>
在resources添加以下两个配置文件: 配置数据库信息,生成的model放在哪里(generatorConfig.xml):
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE generatorConfiguration

<!--指定特定数据库的jdbc驱动jar包的位置-->

</jdbcConnection>
<!-- 非必需,类型处理器,在数据库类型和java类型之间的转换控制-->

<property name="forceBigDecimals" value="false"/>
</javaTypeResolver>
<!-- Model模型生成器,用来生成含有主键key的类,记录类 以及查询Example类
