小白教你如何修改SSM框架的配置资源
1.文件的目录结构
2、spring配置文件applicationContext.xml的配置
<?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: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
http://www.springframework.org/schema/beans/spring-beans-4.3.xsd
http://www.springframework.org/schema/tx

<!-- 读取db.properties -->
<context:property-placeholder location="classpath:db.properties"/>
<!-- 配置数据源 -->
<bean id="dataSource" class="org.apache.commons.dbcp2.BasicDataSource">
<!--数据库驱动 -->
<property name="driverClassName" value="${jdbc.driver}" />
<!--连接数据库的url -->
<property name="url" value="${jdbc.url}" />
<!--连接数据库的用户名 -->
<property name="username" value="${jdbc.username}" />
<!--连接数据库的密码 -->
<property name="password" value="${jdbc.password}" />
<!--最大连接数 -->
<property name="maxTotal" value="${jdbc.maxTotal}" />
<!--最大空闲连接 -->
<property name="maxIdle" value="${jdbc.maxIdle}" />
<!--初始化连接数 -->
<property name="initialSize" value="${jdbc.initialSize}" />
</bean>
<!-- 事务管理器，依赖于数据源 -->
<bean id="transactionManager" class=
"org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource" />
</bean>
<!-- 开启事务注解 -->
<tx:annotation-driven transaction-manager="transactionManager"/>
<!-- 配置MyBatis工厂SqlSessionFactory -->
<bean id="sqlSessionFactory"
class="org.mybatis.spring.SqlSessionFactoryBean">
<!--注入数据源 -->
<property name="dataSource" ref="dataSource" />
<!--指定核MyBatis心配置文件位置 -->
<property name="configLocation" value="classpath:mybatis-config.xml" />
</bean>
<!-- ****************上面的内容为固定内容 无需改动 直接复制即可**************** -->
<!-- 配置mapper扫描器 -->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="basePackage" value="com.itheima.dao"/>
</bean>
<!-- 扫描Service 创建一个service的包 -->
<context:component-scan base-package="com.itheima.service" />
</beans>
------------------------------------------------------------------------------------------
3、MyBatis配置文件mybatis-config.xml的配置
db.properties文件配置
jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/blog?useUnicode=true&characterEncoding=utf8
jdbc.username=root
jdbc.password=root
jdbc.maxTotal=30
jdbc.maxIdle=10
jdbc.initialSize=5
---------------------------------------------------------------------------------------------
mybatis-config.xml的配置
<?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>
<!-- 别名定义 别名不区分大小写-->
<typeAliases>
<!-- 配置扫描包形式，别名就是首类字母小写 -->
<package name="com.itheima.po" />
</typeAliases>
</configuration>
-----------------------------------------------------------------------------------------
4、SpringMVC配置文件springmvc-config.xml的配置
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:tx="http://www.springframework.org/schema/tx"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-4.3.xsd
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc-4.3.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-4.3.xsd">
<!-- 注意这里就给自己的controller的注解类所在文件改 其他不用改 -->
<!-- 配置包扫描器，扫描@Controller注解的类 -->
<context:component-scan base-package="com.itheima.controller" />
<!-- 加载注解驱动 -->
<mvc:annotation-driven />
<!-- 配置视图解析器 -->
<bean class=
"org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/jsp/" />
<property name="suffix" value=".jsp" />
</bean>
</beans>
-----------------------------------------------------------------------------------------
5、web.xml配置文件的配置
<?xml version="1.0" encoding="UTF-8"?>
<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_3_1.xsd"
id="WebApp_ID" version="3.1">
<!-- 配置加载Spring文件的监听器 name名字可以随便取 但是要上下名称一致-->
<context-param>
<param-name>contextConfigLocation</param-name>
<!-- 文件所在路径 -->
<param-value>classpath:applicationContext.xml</param-value>
</context-param>
<listener>
<listener-class>
org.springframework.web.context.ContextLoaderListener
</listener-class>
</listener>
<!-- *********注意点:这里面除了文件的位置路径名称外 其他的都不用改 复制即可******* -->
<!-- 编码过滤器 -->
<filter>
<filter-name>encoding</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>encoding</filter-name>
<url-pattern>*.action</url-pattern>
</filter-mapping>
<!-- 配置Spring MVC前端核心控制器 -->
<servlet>
<servlet-name>springmvc</servlet-name>
<servlet-class>
org.springframework.web.servlet.DispatcherServlet
</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<!-- 文件所在路径 -->
<param-value>classpath:springmvc-config.xml</param-value>
</init-param>
<!-- 配置服务器启动后立即加载Spring MVC配置文件 -->
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>springmvc</servlet-name>
<!--/:拦截所有请求（除了jsp）-->
<url-pattern>/</url-pattern>
</servlet-mapping>
</web-app>
