ssm整合笔记配置文件版
1.创建maven-web项目
2.在pom.xml文件里加入jar包坐标
<?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">

<groupId>com.itheima</groupId>
<artifactId>my_ssm</artifactId>
<version>1.0-SNAPSHOT</version>
<packaging>war</packaging>
<properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
<maven.compiler.source>1.8</maven.compiler.source>
<maven.compiler.target>1.8</maven.compiler.target>
</properties>

<build>
<!--设置插件-->
<plugins>
<!--具体的插件配置-->
<plugin>
<groupId>org.apache.tomcat.maven</groupId>
<artifactId>tomcat7-maven-plugin</artifactId>
<version>2.1</version>
<configuration>
<port>80</port>
<path>/</path>
</configuration>
</plugin>
</plugins>
</build>
</project>
3.创建webapp->WEB-INF->web.xml文件,在配置文件中读入applicationContext.xml和spring-mvc文件
<?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_4_0.xsd"
version="4.0">
<!--启动服务器时,通过监听器加载spring运行环境-->
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<!-- 配置SpringMVC核心控制器,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>classpath*:spring-mvc.xml</param-value>
</init-param>
</servlet>
<servlet-mapping>
<servlet-name>DispatcherServlet</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
<!--乱码处理过滤器,与Servlet中使用的完全相同,差异之处在于处理器的类由Spring提供-->
<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>
</filter>
<filter-mapping>
<filter-name>CharacterEncodingFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath*:applicationContext.xml</param-value>
</context-param>
</web-app>
4.jdbc.properties
jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/ssm_db
jdbc.username=root
jdbc.password=1234
5.application.xml,mybatis整合进去
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:tx="http://www.springframework.org/schema/tx"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
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/tx http://www.springframework.org/schema/tx/spring-tx.xsd">
<context:component-scan base-package="com.itheima">
<context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
</context:component-scan>
<!--加载properties文件-->
<context:property-placeholder location="classpath*:jdbc.properties"/>
<!--数据源-->
<bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource">
<property name="driverClassName" value="${jdbc.driver}"/>
<property name="url" value="${jdbc.url}"/>
<property name="username" value="${jdbc.username}"/>
<property name="password" value="${jdbc.password}"/>
</bean>
<!--整合mybatis到spring中-->
<bean class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="dataSource"/>
<property name="typeAliasesPackage" value="com.itheima.domain"/>
<!--分页插件-->
<property name="plugins">
<array>
<bean class="com.github.pagehelper.PageInterceptor">
<property name="properties">
<props>
<prop key="helperDialect">mysql</prop>
<!--pageNum<=0 时会查询第一页,pageNum>pageSize(超过总数时),会查询最后一页-->
<prop key="reasonable">true</prop>
</props>
</property>
</bean>
</array>
</property>
</bean>
<!--映射扫描-->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="basePackage" value="com.itheima.dao"/>
</bean>
<!--开启注解式事务-->
<tx:annotation-driven transaction-manager="txManager"/>
<!--事务管理器-->
<bean id="txManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource"/>
</bean>
</beans>
6.springmvc.xml
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
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/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd">
<!--扫描加载所有的控制类-->
<context:component-scan base-package="com.itheima.controller"/>
<!-- 放行静态资源-->
<!--SpringMVC提供的通用资源放行方式-->
<mvc:default-servlet-handler/>
<!--必须组合使用-->
<mvc:annotation-driven>
<!-- 配置后解决中文乱码问题-->
<mvc:message-converters>
<bean class="org.springframework.http.converter.StringHttpMessageConverter">
<constructor-arg value="UTF-8" />
</bean>
</mvc:message-converters>
</mvc:annotation-driven>
<!-- 配置视图解析器-->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<!-- 设置访问前缀-->
<property name="prefix" value="/WEB-INF/page/"/>
<!-- 设置访问后缀-->
<property name="suffix" value=".jsp"/>
</bean>
</beans>
7.domain、controller、service、dao层
8.在resources下建立xxxDao.xml,必须和xxxdao的全类名相同
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper
PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.itheima.dao.UserDao">
<!--添加-->
<insert id="save" parameterType="user">
insert into user(userName,password,realName,gender,birthday)values(#{userName},#{password},#{realName},#{gender},#{birthday})
</insert>
<!--删除-->
<delete id="delete" parameterType="int">
delete from user where uuid = #{uuid}
</delete>
<!--修改-->
<update id="update" parameterType="user">
update user set userName=#{userName},password=#{password},realName=#{realName},gender=#{gender},birthday=#{birthday} where uuid=#{uuid}
</update>
<!--查询单个-->
<select id="get" resultType="user" parameterType="int">
select * from user where uuid = #{uuid}
</select>
<!--分页查询-->
<select id="getAll" resultType="user">
select * from user
</select>
<!--登录-->
<select id="getByUserNameAndPassword" resultType="user" >
select * from user where userName=#{userName} and password=#{password}
</select>
</mapper>
