【SSM】Spring+SpringMVC+mybatis入门（环境搭建）

已经大三了，想到快要工作实习，在大二时做了一个android APP的项目，最近和同学一起做一个项目，指导老师让我们用Spring框架，记录我自己学习ssm框架完成crud的整个过程。

开发环境windows+idea2017.1.5

1、新建一个maven项目

首先点击 File - New Project - 选择maven ，并且在右面选择maven-archtype-webapp选项，如图所示

点击next后，出现填写GroupId和Artifactid，其中1. GroupId写com.***.项目2. Artifactid写你的项目名称然后一直next即可

2.项目目录结构

其中java目录是自己添加，且设置为Sources Root。方法：选中目录->右键->Make Directory as->Sources Root。

3.配置文件

3.dispatcherServlet-servlet.xml

4.web.xml

<!--<!DOCTYPE web-app PUBLIC-->        <!--"-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"-->        <!--"http://java.sun.com/dtd/web-app_2_3.dtd" >--><web-app>    <display-name>Archetype Created Web Application</display-name>    <!-- 1.启动Spring容器：业务逻辑 -->    <context-param>        <param-name>contextConfigLocation</param-name>        <param-value>classpath:applicationContext.xml        </param-value>    </context-param>    <listener>        <listener-class>org.springframework.web.context.ContextLoaderListener        </listener-class>    </listener>    <!-- 2.SpringMVC前端控制器：拦截所有请求 -->    <servlet>        <servlet-name>dispatcherServlet</servlet-name>        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>    </servlet>    <servlet-mapping>        <servlet-name>dispatcherServlet</servlet-name>        <url-pattern>/</url-pattern>    </servlet-mapping>    <!--字符编码过滤器-->    <filter>        <filter-name>characterEncodingFilter</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>        <init-param>            <param-name>forceRequestEncoding</param-name>            <param-value>true</param-value>        </init-param>        <init-param>            <param-name>forceResponseEncoding</param-name>            <param-value>true</param-value>        </init-param>    </filter>    <filter-mapping>        <filter-name>characterEncodingFilter</filter-name>        <url-pattern>/*</url-pattern>    </filter-mapping>    <!--配置Rest风格的过滤器，过滤请求为put请求和delete请求-->    <filter>        <filter-name>hiddenHttpMethodFilter</filter-name>        <filter-class>org.springframework.web.filter.HiddenHttpMethodFilter</filter-class>    </filter>    <filter-mapping>        <filter-name>hiddenHttpMethodFilter</filter-name>        <url-pattern>/*</url-pattern>    </filter-mapping>    <!--配置PUT请求过滤器-->    <filter>        <filter-name>httpPutFormContentFilter</filter-name>        <filter-class>org.springframework.web.filter.HttpPutFormContentFilter</filter-class>    </filter>    <filter-mapping>        <filter-name>httpPutFormContentFilter</filter-name>        <url-pattern>/*</url-pattern>    </filter-mapping></web-app>

5.配置mybatis-config.xml

<?xml version="1.0" encoding="UTF-8" ?><!DOCTYPE configuration        PUBLIC "-//mybatis.org//DTD Config 3.0//EN"        "http://mybatis.org/dtd/mybatis-3-config.dtd"><configuration>    <settings>        <setting name="mapUnderscoreToCamelCase" value="true" />    </settings>    <typeAliases>        <package name="com.copasso.crud.bean"></package>    </typeAliases>    <!--注册分页插件 -->    <plugins>        <plugin interceptor="com.github.pagehelper.PageInterceptor">            <property name="reasonable" value="true" />        </plugin>    </plugins></configuration>

其中还要新建一个dbconfig.properties文件，crud替换为你的数据库名

jdbc.jdbcUrl=jdbc:mysql://localhost:3306/crud?useUnicode=true&characterEncoding=utf-8&useSSL=falsejdbc.driverClass=com.mysql.jdbc.Driverjdbc.user=rootjdbc.password=admin

4.最后的项目结构

这样，三大框架整合完毕。。。
