1.Spring Framework特性 IOC
依赖注入。
面向切面编程，包括spring的声明性事务管理。
Spring mvc web应用程序。
RESTful web service框架
JDBC, JPA, JMS的基础支持
1.1
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-context</artifactId>
<version>4.3.3.RELEASE</version>
</dependency>
1.2 注解所需要 在 applicationContext.xml 中配置如下(Spring-IOC有关-->注解)

<?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"
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">

<!-- 配置自动扫描的包，包含所有子包 -->
<context:component-scan base-package="com.captain.demo.springdemo"/>
… …

2.Spring AOP
--2.1 .
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-aspects</artifactId>
<version>4.3.3.RELEASE</version>
</dependency>
2.2
添加spring扫描
xmlns:aop="http://www.springframework.org/schema/aop"
http://www.springframework.org/schema/aop
http://www.springframework.org/schema/aop/spring-aop.xsd

<context:component-scan base-package="com.captain.demo.springdemo"/>

<aop:aspectj-autoproxy></aop:aspectj-autoproxy>

<bean id="logAspect" class="com.captain.demo.aopdemo.LogAspect"></bean>

<!-- aop配置 -->
<aop:config>
    <!-- 切点 -->
    <aop:pointcut id="aop" expression=
        "execution(public void com.captain.demo.aopdemo.AopService.*(..))"/>
    <!-- 切面 : ref 的值是 切面类的id-->
    <aop:aspect id="aspect" ref="logAspect">
        <!-- 前置方法 : pointcut-ref 的值是 切点的id -->
        <aop:before method="afterMethod" pointcut-ref="aop"/>
    </aop:aspect>
</aop:config>

二、Spring-MVC
1.1 maven中引用Spring-MVC

<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-webmvc</artifactId>
<version>4.3.3.RELEASE</version>
</dependency>

1.2 创建springmvc配置文件
------创建：applicationServlet.xml
------默认配置文件：根目录dispatcher-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: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
http://www.springframework.org/schema/context/spring-context.xsd
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc.xsd">

<context:component-scan base-package="com.captain.demo.web" />

<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/"/>
<property name="suffix" value=".jsp"/>
</bean>

1.3 web.xml添加支持 (application.xml和selvelt.xml)
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" version="2.5">

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

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

<servlet>
<servlet-name>springmvc</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:spring/applicationServlet.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>

<servlet-mapping>
<servlet-name>springmvc</servlet-name>
<url-pattern>*.do</url-pattern>
</servlet-mapping>

<filter>
<filter-name>encodingFilter</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>encodingFilter</filter-name>
<url-pattern>*.do</url-pattern>
</filter-mapping>
... ...
</web-app>

1.4在maven中引用SpringTest

<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-test</artifactId>
<version>4.3.3.RELEASE</version>
</dependency>

1.41 .测试用例添加注解 1
@RunWith(SpringJUnit4ClassRunner.class)
使用junit4进行测试
@ContextConfiguration
({"/spring/applicationContext.xml",
"/spring/applicationServlet.xml"})
加载配置文件，多个文件逗号分隔
@TransactionConfiguration(defaultRollback = false)
配置默认回滚

Spring-Web测试 1

模拟request
MockHttpServletRequest request
模拟response
MockHttpServletResponse response
执行前初始化request和response
request = new MockHttpServletRequest();
request.setCharacterEncoding("UTF-8");
response = new MockHttpServletResponse();
设置传入值
request.setParameter("username", "张三");
request.setParameter("password", "123456");

三.Mybatis

3.1
<dependency>
<groupId>org.mybatis</groupId>
<artifactId>mybatis</artifactId>
<version>3.2.5</version>
</dependency>
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>5.1.40</version>
</dependency>

3.2 mybatis的配置文件（mybatis-config.xml随便命名），包含了对MyBatis系统的核心设置。

<?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>
<environments default="development">
<environment id="development">
<transactionManager type="JDBC"/>
<dataSource type="POOLED">
<property name="driver" value="com.mysql.jdbc.Driver"/>
<property name="url" value="jdbc:mysql://localhost:3306/book?characterEncoding=UTF-8"/>
<property name="username" value="root"/>
<property name="password" value="root"/>
</dataSource>
</environment>
</environments>

<!– 引入sql文件,引入employee.xml 有sql的配置文件-->
<mappers>
    <mapper resource=“employeeMapper.xml"/>
</mappers>

</configuration>
3.3
通过mybatis配置文件（mybatis-config.xml），构建SqlSessionFactory对象
String resource = "mybatis-config.xml";
InputStream inputStream =
Resources.getResourceAsStream(resource);
sessionFactory =
new SqlSessionFactoryBuilder().build(inputStream);

3.4 employeeMapper.xml 中 sql Mapper

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper PUBLIC "-//ibatis.apache.org//DTD Mapper 3.0//EN"
"http://ibatis.apache.org/dtd/ibatis-3-mapper.dtd">
<mapper namespace="com.captain.demo.mybatis.dao.UserDao">
<insert id="insertUser" parameterType="map">
insert into user(id,name,nname,password,createtime,updatetime,
cost,money,usertypeid,phone)
values(#{id},#{name},#{nname},#{password},#{createtime},
#{updatetime},#{cost},#{money},#{usertypeid},#{phone})
</insert>
... ...
</mapper>
