什么是 SSM ？他就是Spring，SpringMVC，Mybatis。
SpringMVC：Controller层，通过实现Model-View-Controller模式来很好地将数据、业务与展现进行分离Spring：Service层处于中间的位置，其中最出名的ioc控制反转和aop面向切面编程Mybatis：用于dao层，和数据库交互
二：整合ssm2.1搭建maven工程（pom.xml导入相关的包）maven中央仓库：maven中央仓库
这里要在pom.xml导入相关的包。相关注释在代码内

在resources中创建mybatis-config.xml（名字可以任意）
创建jdbc的资源文件
以后链接数据库都导入这个资源
jdbc.driver=com.mysql.cj.jdbc.Driverjdbc.url=jdbc:mysql://localhost:3306/ssmjdbc.username=rootjdbc.password=0615具体配置说明
位置有顺序要求 1.引入properties 就是jdbc的配置资源 2.全局舍子（开启驼峰）设置类型别名 3.链接数据库 4.引入映射文件
<?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> <!–位置有顺序要求–> <!–引入properties文件–> <properties resource=”dbconfig.properties”></properties> <!–开启驼峰–> <settings> <setting name=”mapUnderscoreToCamelCase” value=”true”/> </settings> <!–设置类型别名–> <typeAliases> <package name=”com.xbfinal.bean”/> </typeAliases><!–.链接数据库–> <environments default=”development”> <environment id=”development”> <transactionManager type=”JDBC”/> <dataSource type=”POOLED”> <property name=”driver” value=”${jdbc.driver}”/> <property name=”url” value=”${jdbc.url}”/> <property name=”username” value=”${jdbc.username}”/> <property name=”password” value=”${jdbc.password}”/> </dataSource> </environment> </environments> <!–引入映射文件–> <mappers> <!–<mapper resource=”mappers/UserMapper.xml”/>–> <package name=”com.xbfinal.dao”/> </mappers></configuration></configuration>

2.4配置springMVC环境DispatcherServlet
在rWEB-INF下创建DispatcherServlet.xm
详细配置
1.springmvc配置文件 包含网页跳转的控制和配置 2.配置视图解析器 方便页面返回 3.两个标准配置
<?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:mvc=”http://www.springframework.org/schema/mvc” xsi:schemaLocation=”http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context https://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/mvc https://www.springframework.org/schema/mvc/spring-mvc.xsd”> <!–springmvc配置文件 包含网页跳转的控制和配置–> <context:component-scan base-package=”com.xbfinal.controller”> </context:component-scan> <!–配置视图解析器 方便页面返回–> <bean class=”org.springframework.web.servlet.view.InternalResourceViewResolver”> <property name=”prefix” value=”/WEB-INF/views/”/> <property name=”suffix” value=”.jsp”/> </bean> <mvc:view-controller path=”/” view-name=”index”></mvc:view-controller> <!–两个标准配置–> <mvc:default-servlet-handler/><!–将springmvc不能处理的交给tomcat–> <!–支持springmvc更高级的功能：JSR303校验 ajax请求.映射动态请求–> <mvc:annotation-driven/></beans>
??**************************************??
2.5配置web.xml环境
配置内容如下
1启动sprin容器 applicationContext.xml 2.配置springMV的前端控制器DispatcherServlet 拦截所有请求 3.字符编码过滤器 4.HHF过滤器: HiddenHttpMethodFilter支持GET、POST、PUT、DELETE请求。
<web-app xmlns:xsi=”http://www.w3.org/2001/XMLSchema-instance” xmlns=”http://xmlns.jcp.org/xml/ns/javaee” xsi:schemaLocation=”http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_4_0.xsd” id=”WebApp_ID” version=”4.0″><!–1启动sprin容器–> <context-param> <param-name>contextConfigLocation</param-name> <!–classpath:spring文件配置路径 项目启动就会加载这个文件 –> <param-value>classpath:applicationContext.xml </param-value> </context-param><!– 2.配置springMV的前端控制器DispatcherServlet 拦截所有请求–> <servlet> <servlet-name>DispatcherServlet</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <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–> <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>forceResponseEncoding</param-name> <param-value>true</param-value> </init-param> </filter> <filter-mapping> <filter-name>CharacterEncodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <!–HHF过滤器–> <filter> <filter-name>HiddenHttpMethodFilter</filter-name> <!– HHF –> <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>总结
以上就是ssm的基本整合内容先配置mybatis然后配置 spring接下来就是springmvc最后配置一下web.xml
mybatis需要配置那些？
1.引入properties文件 ??<properties resource=””??? 2.全局设置 开启驼峰??<setting name=”mapUnderscoreToCamelCase” value=”true”/>?? 3.设置类型别名??<typeAliases></typeAliases>?? 4链接数据库.??<environments>?? 5.引入映射文件 ??<mappers>??
spring需要配置那些？
1.业务逻辑扫描??<context:component-scan base-package=”com.xbfinal”>??? 2数据源.??<context:property-placeholder location=”dbconfig.properties”/>?? 3.配置和mybatis整合SqlSessionFactoryBean??<bean class=” org.mybatis.spring.SqlSessionFactoryBean”>?? 4.配置扫描器。将mybatis接口实现加入到ioc容器??<bean class=” org.mybatis.spring.mapper.MapperScannerConfigurer”>??
5.事务控制TransactionManager 5.1 控制数据源 5.2开启注解的事务，使用xml配置形式的事务(都使用配置) 5.3配置事务增强，事务如何切入
springmvc需要配置那些？
1.网页跳转的控制和配置??<context:component-scan base-package=”com.xbfinal.controller”>?? 2.配置视图解析器InternalResourceViewResolver 方便页面返回 3.两个标准配置??<mvc:default-servlet-handler/>????<mvc:annotation-driven/>??
web.xml需要配置那些？
1.1启动sprin容器??<context-param>??? 2.配置springMV的前端控制器DispatcherServlet 拦截所有请求??<servlet>?? 3字符编码过滤器CharacterEncodingFilter??<filter>?? 4.HHF过滤器??<filter>??
