1.创建applicationContext.xml配置文件，并添加约束

2.开启注解扫描，并设定扫描的路径（spring只管理的是service和dao）

2.创建springmvc.xml配置文件，添加约束头

3.开启注解扫描、配置View解析器对象、过滤资源、开启springmvc注解支持

4.编写测试代码在代码做好相应注解（测试spring是否可用）

四.spring整合springmvc

2.配置监听器

3.因为监听器只能够加载WEB-INF目录下的配置文件，所以需要设置配置文件

4.使用Autowried设置参数注入

五.mybatis环境搭建

1.在dao层方法上编写相关注解

2.创建SqlMapConfig.xml配置文件并写入约束头

3.配置环境(注意导入jdbc.properties)

4.编写测试代码

六.spring整合mybatis框架（需要在applicationContext.xml文件中配置）

1.配置连接池

2.配置SqlSessionFactory工厂

3.配置dao接口所在包

4.在dao接口类上添加Repositor注解

5.service层类使用Autowired自动获取值

6.测试，在jsp导入el表达式uri做测试

一.jar包环境搭建

1.设置版本

<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>
<spring.version>5.0.2.RELEASE</spring.version>
<slf4j.version>1.6.6</slf4j.version>
<log4j.version>1.2.12</log4j.version>
<mysql.version>5.1.6</mysql.version>
<mybatis.version>3.4.5</mybatis.version>
</properties>

2.引入坐标

<type>jar</type>
<scope>compile</scope>
</dependency>
</dependencies>

3.创建相关package、接口和实现类

controller、dao、domain、service

二.编写spring框架

1.创建applicationContext.xml配置文件，并添加约束

<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/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/tx
   http://www.springframework.org/schema/tx/spring-tx.xsd">

2.开启注解扫描，并设定扫描的路径（spring只管理的是service和dao）


<context:component-scan base-package="cn.gaipian" >



<context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller" />
</context:component-scan>

3.在相关类配置注解

@Service("accountService")
public class AccountServiceImpl implements AccountService{}

4.测试。

注意将junit单元测试坐标设置为compile

<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>4.12</version>
<scope>compile</scope>
</dependency>

注意：导入log4j.properties,不然会出现运行警告

三.编写SpringMVC框架

1.配置前端控制器、中文乱码过滤器


<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:springmvc.xml</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>


<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>

2.创建springmvc.xml配置文件，添加约束头

<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:context="http://www.springframework.org/schema/context"
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/mvc
http://www.springframework.org/schema/mvc/spring-mvc.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context.xsd">

3.开启注解扫描、配置View解析器对象、过滤资源、开启springmvc注解支持


<context:component-scan base-package="cn.itcast">
<context:include-filter type="annotation" expression="org.springframework.stereotype.Controller" />
</context:component-scan>


<bean id="internalResourceViewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/pages/"/>
<property name="suffix" value=".jsp"/>
</bean>


<mvc:resources location="/css/" mapping="/css/**" />
<mvc:resources location="/images/" mapping="/images/**" />
<mvc:resources location="/js/" mapping="/js/**" />


<mvc:annotation-driven/>

4.编写测试代码在代码做好相应注解（测试spring是否可用）

@Controller
@RequestMapping("/account")
public class AccountController {

@RequestMapping("/findAll")
public String findAll(Model model){}

}

四.spring整合springmvc

1.在启动tomcat服务器的时候，需要加载spring的配置文件，需要在服务器启动的时候创建ServletContext对象，在web.xml配置监听器加载spring的配置文件，创建web版本工厂，存储servletContext对象，该监听器依赖的是spring-web坐标

2.配置监听器


<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

3.因为监听器只能够加载WEB-INF目录下的配置文件，所以需要设置配置文件


<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext.xml</param-value>
</context-param>
<context-param>
<param-name/>
<param-value/>
</context-param>

4.使用Autowried设置参数注入

@Autowired
private AccountService accountService

五.mybatis环境搭建

1.在dao层方法上编写相关注解

// 查询所有账户
@Select("select * from account")
public List<Account> findAll();

// 保存帐户信息
@Insert("insert into account (name,money) values (#{name},#{money})")
public void saveAccount(Account account);

2.创建SqlMapConfig.xml配置文件并写入约束头

<?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">

3.配置环境(注意导入jdbc.properties)


<environments default="mysql">

<environment id="mysql">

<transactionManager type="JDBC"></transactionManager>


<dataSource type="POOLED">
<property name="driver" value="${jdbc.driver}"></property>
<property name="url" value="${jdbc.url}"></property>
<property name="username" value="${jdbc.username}"></property>
<property name="password" value="${jdbc.password}"></property>
</dataSource>
</environment>
</environments>


<mappers>
<package name="com.gaipian.dao"></package>
</mappers>

4.编写测试代码

// 加载配置文件
InputStream in = Resources.getResourceAsStream("SqlMapConfig.xml");
// 创建SqlSessionFactory对象
SqlSessionFactory factory = new SqlSessionFactoryBuilder().build(in);
// 创建SqlSession对象
SqlSession session = factory.openSession();
// 获取到代理对象
AccountDao dao = session.getMapper(AccountDao.class);
// 查询所有数据
List<Account> list = dao.findAll();
for(Account account : list){
System.out.println(account);
}
// 关闭资源
session.close();
in.close();

六.spring整合mybatis框架（需要在applicationContext.xml文件中配置）

1.配置连接池


<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
<property name="driverClass" value="com.mysql.jdbc.Driver"/>
<property name="jdbcUrl" value="jdbc:mysql:///ssm"/>
<property name="user" value="root"/>
<property name="password" value="root"/>
</bean>

2.配置SqlSessionFactory工厂

<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="dataSource" />
</bean>

3.配置dao接口所在包


<bean id="mapperScanner" class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="basePackage" value="cn.gaipian.dao"/>
</bean>

4.在dao接口类上添加Repositor注解

@Repository
public interface AccountDao {}

5.service层类使用Autowired自动获取值

@Autowired
private AccountDao accountDao;

6.测试，在jsp导入el表达式uri做测试

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>

<h3>查询所有的帐户</h3>

<c:forEach items="${list}" var="account">
${account.name}
</c:forEach>

七.配置事务管理

1.配置事务管理器



<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource" />
</bean>

2.配置事务通知


<tx:advice id="txAdvice" transaction-manager="transactionManager">
<tx:attributes>
<tx:method name="find*" read-only="true"/>
<tx:method name="*" isolation="DEFAULT"/>
</tx:attributes>
</tx:advice>

3.配置aop增强


<aop:config>
<aop:advisor advice-ref="txAdvice" pointcut="execution(* cn.itcast.service.impl.*ServiceImpl.*(..))"/>
</aop:config>
