准备做一个SpringMVC_CRM系统系列，本系列主要是演示使用SpringMVC+Mybatis来完整一个简单的CRM系统，今天开始第一章，搭建环境。

创建一个SpringMVC项目
创建完成后右键项目名称，添加maven支持

在pom.xml中增加以下内容，这里我把整个项目要用的都加进来了，后续就不再一一加了

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"

        </configuration>
        </plugin>
        </plugins>
    </build>
    
</project>

配置tomcat

选择Deployment ，点＋号，这里不要配置错了
修改项目文件结构，这里我对默认的结构做了修改，applicationContext.xml放到了resources文件夹下，在main下面建了webapp文件夹，放置WEB-INF

这个resources文件夹如果不识别，需要在maven中配置一下,maven只会把resource目录下的所有文件复制到classpath下，而源码目录里就只会把.java文件编译输出，想要把源码目录里的其他文件输出，就要配置resource

<build>
    <finalName>你项目名</finalName>
    <resources>
        <resource>
            <directory>src/main/resources</directory>
        </resource>
        <resource>
            <directory>src/main/java</directory>
            <includes>
                <include>**/*.xml</include>
                <include>**/*.properties</include>
            </includes>
        </resource>
    </resources>
</build>

配置web.xml

<?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">
    <!-- 添加展示名称 -->
    <display-name>SpringMvcCRM</display-name>
    <servlet>
        <servlet-name>mvc-dispatcher</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath:*.xml</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>


    <servlet-mapping>
        <servlet-name>mvc-dispatcher</servlet-name>
        <!-- 设置所有以action结尾的请求进入SpringMVC -->
        <url-pattern>/</url-pattern>
    </servlet-mapping>

 <!--处理从页面传递中文到后台而出现的中文乱码问题-->
    <filter>
        <filter-name>encodingFilter</filter-name>
        <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
        <init-param>
            <param-name>encoding</param-name>
            <param-value>UTF-8</param-value>
        </init-param>
    </filter>
    <filter-mapping>
        <filter-name>encodingFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

</web-app>

mvc-dispatcher-servlet.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:context="http://www.springframework.org/schema/context"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd">
    <context:component-scan base-package="com.spring.crm">
    </context:component-scan>
</beans>

测试，新建一个MainController

package com.spring.crm.controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;

@Controller
public class MainController {

    @RequestMapping("/index")
    @ResponseBody
    public String index(){
        return "index";
    }
}

启动tomcat，访问 http://localhost:8080/index 能看到页面显示index就成功了

总结

今天的搭建环境就到这了，下一节我们继续讲配置数据库
