1. Spring框架编写
1.1 创建Application配置文件
- 因为Controller后续会交给SpringMvc管理,所以我们这的配置文件不需要管理Controller注解
-
关于为什么要向这样做,我们最后做解释:
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:aop="http://www.springframework.org/schema/aop"
xmlns:tx="http://www.springframework.org/schema/tx"
xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="http://www.springframework.org/schema/beans
https://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/tx
https://www.springframework.org/schema/tx/spring-tx.xsd
http://www.springframework.org/schema/aop
https://www.springframework.org/schema/aop/spring-aop.xsd
http://www.springframework.org/schema/context
https://www.springframework.org/schema/context/spring-context.xsd">
<!-- 注解扫描,忽略Controller -->
<context:component-scan base-package="com.atjianyi">
<context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
</context:component-scan>
2. SpringMvc框架编写
2.1 创建Springmvc-config文件
- 同样在resources目录下
- 编写Springmvc配置文件
关于SpringMvc,我们只需要管理controller就可以了,所以配置注解包扫描时候,只需要关注Controller注即可。
<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-3.0.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spri ng-context.xsd
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc.xsd">
<!-- 配置注解扫描 -->
<context:component-scan base-package="com.atjianyi">
<context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
</context:component-scan>
<!-- 配置视图解析器 -->
<bean id="is" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/pages/"/>
<property name="suffix" value=".jsp"/>
</bean>
<!-- 静态资源过滤 -->
<mvc:resources mapping="/js/**" location="/js/"/>
<mvc:resources mapping="/css/**" location="/css/"/>
<mvc:resources mapping="/img/**" location="/img/"/>
<!-- 支持Springmvc框架 -->
<mvc:annotation-driven/>
</beans>
2. 2 配置前端控制器
<!-- Spring Mvc start前端控制器 -->
<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:springmvc-config.xml</param-value>
</init-param>
</servlet>
<servlet-mapping>
<servlet-name>springmvc</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
<filter>
<filter-name>charsetFilter</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>charsetFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
<!-- SpringMvc end -->
3. Spring与SpringMvc整合
3.1 Spring与SpringMvc整合说明
当我们的服务器启动时候,我们需要服务器去帮助我们创建IOC容器,也就是需要去加载我们的applicationContext配置文件。
3.2 Spring与SpringMvc整合思路
- ServletContext域对象
- 服务器启动时候,就创建,服务器关闭,就执行销毁
- 一类监听器
- 能监听ServletContext域对象的创建和销毁
- ContextLoadListen.对象
3.3 在webXML中注册监听并且去加载Spring配置文件
<!-- Spring -->
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext.xml</param-value>
</context-param>
<!-- Spring End -->
默认他会去WEB-INF目录下找applicationContext.xml文件,但是我们的配置文件同一在resources下管理,所以我们使用context-param去更改。
4. Mybatis框架编写
直接跳过,看5.因为我们Spring与Mybatis整合,Mybatis将其中的SqlSeesionFactory对象,连接池对象等。同一交给Spring去管理就行,省去了我们手动编写环境标签的步骤…
5. Spring与Mybatis框架整合
5. 1. 创建Mybatis-config的配置文件。
5.1.1 编写mybatis-config配置文件配置
<?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>
<typeAliases>
<package name="com.atjianyi.domain"/>
</typeAliases>
<!--与Spring整合,我们无需去编写环境,甚至将mapper都交给了Spring-->
</configuration>
5.2 applciationContext.xml文件新增配置
<!--Mybatis-->
<!-- 配置连接池 -->
<!-- 我们目前使用的druid数据库连接池,此处可以根据不同数据库连接池而定 -->
<context:property-placeholder location="classpath:jdbc-config.properties"/>
<!-- 创建数据源 -->
<bean id="ds" class="com.alibaba.druid.pool.DruidDataSourceFactory" factory-method="createDataSource">
<constructor-arg name="properties">
<props>
<prop key="url">${url}</prop>
<prop key="driverClass">${driverClass}</prop>
<prop key="username">${username}</prop>
<prop key="password">${password}</prop>
</props>
</constructor-arg>
</bean>
<!-- 配置SqlSession工厂 -->
<bean class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="ds"/>
</bean>
<!-- 配置包扫描 -->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="basePackage" value="com.atjianyi.dao"/>
</bean>
