<include>**/*.properties</include>
<include>**/*.xml</include>
</includes>
<filtering>false</filtering>
</resource>
</resources>
</build>
二.配置文件详情
1.基于mybatis配置
1.sqlMapConfig.xml如下：
<!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>
<settings>
<!--开启驼峰命名-->
<setting name="mapUnderscoreToCamelCase" value="true"/>
</settings>
<!--开启别名-->
<typeAliases>
<!--该包下面的所有类不用引用全类名，直接使用类的名字即可无视大小写-->
<package name="com.shiyan.bean"/>
</typeAliases>
<!--查询sql映射文件，项目启动的时候加载这个mappers配置，-->
<mappers>
<!--resource相对于java和resource下的文件，
加载该文件下面的salMapper接口的配置文件，通过找到的这个配置文件加载这个接口及接口方法-->
<mapper resource="Mapper/CustomerMapper.xml"/>
</mappers>
<!--分页插件，便于分页-->
<plugins>
<plugin interceptor="com.github.pagehelper.PageInterceptor"> </plugin>
</plugins>
</configuration>
2.applicationConfing.xml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: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.xsd
http://www.springframework.org/schema/context
https://www.springframework.org/schema/context/spring-context.xsd
http://www.springframework.org/schema/tx
http://www.springframework.org/schema/tx/spring-tx.xsd">
<!--加载springMvc.xml的配置归于IOC容器管理，并且使applicationConfing文件在服务启动就加载-->
<import resource="classpath:spring-mvc.xml"/>
<!--相当于Mybatis层的配置，读取jdbc.properties的数据库配置-->
<context:property-placeholder location="classpath:jdbc.properties"/>
<!--创建数据源-->
<bean class="org.apache.commons.dbcp.BasicDataSource" id="dataSource">
<property name="driverClassName" value="${jdbc.driver}"/>
<property name="url" value="${jdbc.url}"/>
<property name="username" value="${jdbc.username}"/>
<property name="password" value="${jdbc.password}"/>
<!--最大连接数-->
<property name="maxActive" value="10"/>
<!--最大空闲数-->
<property name="maxIdle" value="5"/>
</bean>
<!--创建SqlSessionFactory对象-->
<bean class="org.mybatis.spring.SqlSessionFactoryBean" id="sqlSessionFactory">
<!--关联连接池-->
<property name="dataSource" ref="dataSource"/>
<!--加载sql映射文件 value="classpath:Mapper/CustomerMapper.xml-->
<property name="mapperLocations" value="classpath:Mapper/*.xml"/>
</bean>
<!--方式一（不推荐使用）：需要创建CustomerMappperImol对象，并在该对象中注入SqlSessionFactory-->
<!--方式二：配置mapper接口-->
<!-- <bean class="org.mybatis.spring.mapper.MapperFactoryBean" id="customerMapper">
<!–关联要使用的Mapper接口–>
<property name="mapperInterface" value="com.shiyan.dao.CustomerMapper"/>
<!–关联SqlSessionFactory–>
<property name="sqlSessionFactory" ref="sqlSessionFactory"/>
</bean>-->
<!--方式三：mapper接口的扫描，只需要注册这个类MapperScannerConfigurer，并使用所以不用配置id-->
<!--使用这种Mapper接口扫描的方式进行配置，那么每一个Mapper接口在Spring容器中的名称id为类名首字母小写-->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer" >
<!--配置mapper接口所在的包的路径,自动扫描并加载这个包下面的所有mapper接口-->
<property name="basePackage" value="com.shiyan.dao"/>
</bean>
<!--开启Spring的IOC注解的扫描，将Service和Repository加入IOC容器-->
<context:component-scan base-package="com.shiyan"/>
<!--开启Spring事务，相当于Service层配置-->
<!--事务管理器-->
<bean class="org.springframework.jdbc.datasource.DataSourceTransactionManager" id="transactionManager">
<!--关联dataSource数据源，对数据库的事务进行管理-->
<property name="dataSource" ref="dataSource"/>
</bean>
<!--启用Spring事务的注解操作,关联上面的transactionManager就可以使用注解对某一个service业务进行事务的管理-->
<!-- 在需要被事务管理的service业务类上添加 @Transactional这个注解即可
@Transactional
public class CustomerServiceImpl implements CustomerService {
-->
<tx:annotation-driven transaction-manager="transactionManager"/>
</beans>
3.基于mysql的jdbc.properties文件
jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/ssm?characterEncoding=utf-8
jdbc.username=""
jdbc.password=""
4.springMvc.xml配置文件
<?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:mvc="http://www.springframework.org/schema/mvc"
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/mvc
http://www.springframework.org/schema/mvc/spring-mvc.xsd
http://www.springframework.org/schema/context
https://www.springframework.org/schema/context/spring-context.xsd">
<!--1.开启注解驱动-->
<mvc:annotation-driven/>
<!--2.静态资源过滤，js和css，图片等各种静态资源-->
<mvc:default-servlet-handler/>
<!--3.扫描包：controller。哪些类上加了controller就是前端控制器-->
<context:component-scan base-package="com.shiyan.controller"/>
<!--4.配置视图解析器，指定controller返回的视图前缀和后缀-->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/>
<!--前缀-->
<property name="prefix" value="/WEB-INF/jsp/"/>
<!--后缀-->
<property name="suffix" value=".jsp"/>
</bean>
</beans>
5.log4g.properties配置
#定义输出级别
log4j.rootLogger=DEBUG,Console,File
#日志输出方式：控制台输出
log4j.appender.Console=org.apache.log4j.ConsoleAppender
log4j.appender.Console.Target=System.out
log4j.appender.Console.Encoding=GBK
#可以灵活地指定布局模式
log4j.appender.Console.layout=org.apache.log4j.PatternLayout
#log4j.appender.Console.layout.ConversionPattern = %d{yyyy-MM-dd HH:mm:ss.SSS} -%p (%F\:%L)- %m%n
#打印格式栗子：2017-08-11 15:36 -DEBUG (HttpServletBean.java:174)- Servlet 'mvc' configured successfully
log4j.appender.Console.layout.ConversionPattern = %d{yyyy-MM-dd HH:mm} -%p (%F\:%L)- %m%n
### 打印SQL ###
#log4j.logger.com.ibatis=DEBUG
#log4j.logger.com.ibatis.common.jdbc.SimpleDataSource=DEBUG
#log4j.logger.com.ibatis.common.jdbc.ScriptRunner=DEBUG
#log4j.logger.com.ibatis.sqlmap.engine.impl.SqlMapClientDelegate=DEBUG
log4j.logger.java.sql.Connection=DEBUG
log4j.logger.java.sql.Statement=DEBUG
log4j.logger.java.sql.PreparedStatement=DEBUG
#log4j.logger.java.sql.ResultSet=DEBUG
6.Mapper文件夹下面的Mapper.xml（相当于Dao接口的实现类）配置
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<!--命名空间，即要映射的Dao接口的全类名。按住CTRL点击这个类名能跳转到Dao接口就配置完成了-->
<mapper namespace="com.shiyan.dao.CustomerMapper">
<!--查询全部，id必须是Dao接口的方法名才能，在sqlMapConfig.xml文件配置别名后 resultType可以使用取的别名，自动添加包扫描别名默认是该类名Customer-->
<select id="findAll" resultType="com.shiyan.domain.Customer">
select * from t_customer;
</select>
</mapper>
7.web.xml配置
<?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spring其内部包含springmvc和mybatis的配置一起加载-->
<servlet>
<servlet-name>DispatcherServlet</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<!--初始化参数：读取spring-mvc.xml的配置文件-->
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext.xml</param-value>
</init-param>
</servlet>
<servlet-mapping>
<servlet-name>DispatcherServlet</servlet-name>
<!--
/:拦截所有请求不拦截 .jsp
/*:拦截所有的请求宝库jsp页面
-->
<url-pattern>/</url-pattern>
</servlet-mapping>
<!--配置编码过滤器-->
<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>
</web-app>
基本框架搭建完成后就可以很方便的编写Controller和视图了
