技术点
1.基础框架-ssm （SpringMVC +Spring +MyBatis）
2.数据库MySqQL
3.前端框架-bootstrap快速搭建简洁美观的界面
4.项目的依赖管理-Maven
5.分页-pagehelper
6.逆向工程-MyBatis Generator
------------------------------------------------------------------------------------------------------------------------------
基础环境搭建
1.创建一个maven工程
2.引入项目依赖的jar包
spring
springmvc
mybatis
数据库连接池，驱动包
其他（jstl，servlet-api，junit）
3.引入bootstrap前端框架
4.编写ssm整合的关键配置文件
web.xml，spring,springmvc,mybatis
------------------------------------------------------------------------------------------------------------------------------
1、修改settings.xml
这下面是阿里巴巴的仓库。这样下载jar包会比较快
<mirrors>
<!-- mirror
| Specifies a repository mirror site to use instead of a given repository. The repository that
| this mirror serves has an ID that matches the mirrorOf element of this mirror. IDs are used
| for inheritance and direct lookup purposes, and must be unique across the set of mirrors.
| -->
<mirror>
<id>alimaven</id>
<name>aliyun maven</name>
<url>http://maven.aliyun.com/nexus/content/groups/public/</url>
<mirrorOf>central</mirrorOf>
</mirror> </mirrors>
在profiles中加入jdk的版本，这样编译时就不会报一些莫名其妙的错误
<profiles>
<profile>
<id>jdk-1.7</id>
<activation>
<activeByDefault>true</activeByDefault>
<jdk>1.7</jdk>
</activation>
<properties>
<maven.compiler.source>1.7</maven.compiler.source>
<maven.compiler.target>1.7</maven.compiler.target>
<maven.compiler.compilerVersion>1.7</maven.compiler.compilerVersion>
</properties>
</profile>
</profiles>
依赖包pom.xml：
查找jar包的时候自己注意下。查的哪个下面的。得找对了
2、引入jar包
<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/maven-v4_0_0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId>com.dotcore</groupId>
<artifactId>ssm</artifactId>
<packaging>war</packaging>
<version>1.0-SNAPSHOT</version>
<!--引入项目依赖的jar包 -->
<dependencies>
<!--版本对应都是用4.3.7.RELEASE -->

</dependency>
<!--Spring JDBC -->
<!-- https://mvnrepository.com/artifact/org.springframework/spring-jdbc -->
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-jdbc</artifactId>
<version>4.3.7.RELEASE</version>
</dependency>
<!--Spring 面向切面编程 -->
<!-- https://mvnrepository.com/artifact/org.springframework/spring-aspects -->
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-aspects</artifactId>
<version>4.3.7.RELEASE</version>
</dependency>
<!--MyBatis -->
<!-- https://mvnrepository.com/artifact/org.mybatis/mybatis -->
<dependency>
<groupId>org.mybatis</groupId>
<artifactId>mybatis</artifactId>
<version>3.4.2</version>
</dependency>
<!--MyBatis整合Spring的适配包 -->
<!-- https://mvnrepository.com/artifact/org.mybatis/mybatis-spring -->
<dependency>
<groupId>org.mybatis</groupId>
<artifactId>mybatis-spring</artifactId>
<version>1.3.0</version>
</dependency>
<!--数据库连接池 -->
<!-- https://mvnrepository.com/artifact/c3p0/c3p0 -->
<!-- 这里是用c3p0的方式，查询的时候是c3p0下的c3p0-->
<dependency>
<groupId>c3p0</groupId>
<artifactId>c3p0</artifactId>

</dependency>
<!-- https://mvnrepository.com/artifact/junit/junit -->
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>4.12</version>
</dependency> </dependencies>
</project>
3、引入bootstrap前端框架
页面用到bootstrap插件的引用
<html>
<body>
<!--引入JQuery -->
<script src="static/js/jquery-1.12.4.min.js"></script>
<!--引入样式 -->
<link href="static/bootstrap-3.3.7-dist/css/bootstrap.min.css" rel="stylesheet">
<script src="static/bootstrap-3.3.7-dist/js/bootstrap.min.js"></script>
<h2>Hello World!</h2>
</body>
</html>
4、编写ssm整合的关键配置文件（重点来了）
web.xml文件配置
<?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">
<!--1. 启动Spring的容器-->
<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的前端控制器，拦截所有请求 -->
<servlet>
<servlet-name>dispatcherServlet</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<!--<init-param>-->
<!--<param-name>contextConfigLocation</param-name>-->
<!--<<param-value>location</param-value>-->
<!--</init-param>-->
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>dispatcherServlet</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping> <!--3.字符编码过滤器 ,一定放在所有的过滤器之前-->
<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> <!--4.使用Rest风格的URI，将页面的普通post请求转为制定的delete请求或者put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>
</web-app>
web.xml文件配置完了后，就开始配置springmvc的配置文件（dispatcherServlet-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:p="http://www.springframework.org/schema/p"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-4.0.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-4.0.xsd
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd"> <!--SpringMVC的配置文件，包含网站跳转逻辑的控制，配置 （跟网站逻辑有关的，放在这）-->
<context:component-scan base-package="com.dotcore" use-default-filters="false">
<!--只扫描控制器 得把默认的改为false-->
<context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
</context:component-scan> <!--配置视图解析器 -->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/views"/>
<property name="suffix" value=".jsp"/>
</bean> <!--两个标准配置 -->
<!--将Springmvc不能处理的请求交给tomcat -->
<mvc:default-servlet-handler/>
<!--能支持springmvc更高级的一些功能，JSR303,快捷的ajax请求 -->
<mvc:annotation-driven/>
</beans>
配置dbconfig.properties数据源的常量
jdbc.jdbcUrl = jdbc:mysql://localhost:3306/ssm_crud
jdbc.driverClass = com.mysql.jdbc.Driver
jdbc.user=root
jdbc.password=123456
SSM整合配置_配置Spring
<?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"
xmlns:aop="http://www.springframework.org/schema/aop"
xmlns:tx="http://www.springframework.org/schema/tx"
xsi:schemaLocation="http://www.springframework.org/schema/beans

http://www.springframework.org/schema/aop/spring-tx-4.0.xsd"> <!--这边不扫描控制器 -->
<context:component-scan base-package="com.dotcore">
<context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
</context:component-scan> <!-- spring的配置文件，这里主要配置和业务逻辑有关的-->
<!-- 数据源，事务处理xxxx-->
<context:property-placeholder location="classpath:dbconfig.properties"/> <bean id="pooledDataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
<property name="jdbcUrl" value="${jdbc.jdbcUrl}"/>
<property name="driverClass" value="${jdbc.driverClass}"></property>
<property name="user" value="${jdbc.user}"></property>
<property name="password" value="${jdbc.password}"></property>
</bean>
<!-- 数据源，事务处理xxxx--> <!--配置和mybatis的整合 -->
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<!--指定mybatis全局配置文件的位置-->
<property name="configLocation" value="classpath:mybatis-config.xml"></property>
<property name="dataSource" ref="pooledDataSource"/>
<!--指定mybatis，mapper文件的位置-->
<property name="mapperLocations" value="classpath:mapper/*.xml"/>
</bean> <!--配置扫描器，将mybatis接口的实现加入到ioc容器中-->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<!-- 扫描所有dao接口的实现，加入到ioc容器中-->
<property name="basePackage" value="com.dotcore.dao"></property>
</bean>
<!--配置和mybatis的整合 --> <!--事务控制的配置-->
<!--事务管理器 -->
<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<!--控制住数据源-->
<property name="dataSource" ref="pooledDataSource"/>
</bean> <!-- 开启基于注解的事务，使用xml配置形式的事务（必要主要的都是使用配置式） -->
<aop:config>
<!--切入点表达式-->
<aop:pointcut id="txPoint" expression="execution(* com.dotcore.service..*(..))"></aop:pointcut>
<!--配置事务增强-->
<aop:advisor advice-ref="txAdvice" pointcut-ref="txPoint"/>
</aop:config> <!--配置事务增强,事务如何切入-->
<tx:advice id="txAdvice" transaction-manager="transactionManager">
<tx:attributes>
<!--所有方法都是事务方法-->
<tx:method name="*"/>
<!--以get开始的所有方法-->
<tx:method name="get*" read-only="true"/>
</tx:attributes>
</tx:advice>
<!--事务控制的配置--> <!-- Spring配置文件的核心点（数据源，与mybatis的整合，事务控制）-->
</beans>
最后mybatis的配置文件
<?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>
<!--驼峰命名规则-->
<settings>
<setting name="mapUnderscoreToCamelCase" value="true"/>
</settings>
<!--别名-->
<typeAliases>
<package name="com.dotcore.model"/>
</typeAliases>
</configuration>
这样，相关的配置文件都配置完毕了
最后配置一张项目的结构图
