SSM小书城整合，老手框架整合练习

所有文件都在github（https://github.com/laowenruo/...）

本我的项目次要用于用于老手刚入门Spring，Mybatis,SpringMVC框架后，须要小练手整合一下，相熟完框架之后，还是能够深刻学习一下或者学下Springboot等内容(如果本我的项目对您有帮忙，请 watch、star、fork 素质三连一波，激励一下作者，谢谢）

数据库环境

创立一个寄存书籍数据的数据库表
文件为数据库.sql

根本环境搭建

新建一Maven我的项目！增加web的反对
导入相干的pom依赖！
文件为pom.xml
文件为Maven资源过滤设置,动态资源导出问题

<build>   <resources>       <resource>           <directory>src/main/java</directory>           <includes>               <include>**/*.properties</include>               <include>**/*.xml</include>           </includes>           <filtering>false</filtering>       </resource>       <resource>           <directory>src/main/resources</directory>           <includes>               <include>**/*.properties</include>               <include>**/*.xml</include>           </includes>           <filtering>false</filtering>       </resource>   </resources></build>

建设根本构造和配置框架！

Mybatis层编写

数据库配置文件 database.properties

jdbc.driver=com.mysql.jdbc.Driver# &serverTimezone=Asia/Shanghaijdbc.url=jdbc:mysql://localhost:3306/ssmbuild?useSSL=true&useUnicode=true&characterEncoding=utf8jdbc.username=rootjdbc.password=123456

编写MyBatis的外围配置文件 mybatis-config.xml

<?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.kuang.pojo"/>   </typeAliases>   <mappers>       <mapper resource="com/kuang/dao/BookMapper.xml"/>   </mappers></configuration>

编写数据库对应的实体类 com.pojo.Books，可应用lombok插件！
编写Dao层的 Mapper接口！
编写接口对应的 Mapper.xml 文件。须要导入MyBatis的包；
编写Service层的接口和实现类

Spring层

配置Spring整合MyBatis，咱们这里数据源应用c3p0连接池；
咱们去编写Spring整合Mybatis的相干的配置文件；spring-dao.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"      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">   <!-- 配置整合mybatis -->   <!-- 1.关联数据库文件 -->   <context:property-placeholder location="classpath:database.properties"/>   <!-- 2.数据库连接池 -->   <!--数据库连接池       dbcp 半自动化操作 不能主动连贯       c3p0 自动化操作（主动的加载配置文件 并且设置到对象外面）   -->   <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">       <!-- 配置连接池属性 -->       <property name="driverClass" value="${jdbc.driver}"/>       <property name="jdbcUrl" value="${jdbc.url}"/>       <property name="user" value="${jdbc.username}"/>       <property name="password" value="${jdbc.password}"/>       <!-- c3p0连接池的公有属性 -->       <property name="maxPoolSize" value="30"/>       <property name="minPoolSize" value="10"/>       <!-- 敞开连贯后不主动commit -->       <property name="autoCommitOnClose" value="false"/>       <!-- 获取连贯超时工夫 -->       <property name="checkoutTimeout" value="10000"/>       <!-- 当获取连贯失败重试次数 -->       <property name="acquireRetryAttempts" value="2"/>   </bean>   <!-- 3.配置SqlSessionFactory对象 -->   <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">       <!-- 注入数据库连接池 -->       <property name="dataSource" ref="dataSource"/>       <!-- 配置MyBaties全局配置文件:mybatis-config.xml -->       <property name="configLocation" value="classpath:mybatis-config.xml"/>   </bean>   <!-- 4.配置扫描Dao接口包，动静实现Dao接口注入到spring容器中 -->   <!--解释 ：https://www.cnblogs.com/jpfss/p/7799806.html-->   <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">       <!-- 注入sqlSessionFactory -->       <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/>       <!-- 给出须要扫描Dao接口包 -->       <property name="basePackage" value="com.kuang.dao"/>   </bean></beans>

Spring整合service层，Spring-service.xml文件编写

<?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">   <!-- 扫描service相干的bean -->   <context:component-scan base-package="com.service" />   <!--BookServiceImpl注入到IOC容器中-->   <bean id="BookServiceImpl" class="com.service.BookServiceImpl">       <property name="bookMapper" ref="bookMapper"/>   </bean>   <!-- 配置事务管理器 -->   <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">       <!-- 注入数据库连接池 -->       <property name="dataSource" ref="dataSource" />   </bean></beans>

SpringMVC层

web.xml编写

<?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">   <!--DispatcherServlet-->   <servlet>       <servlet-name>DispatcherServlet</servlet-name>       <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>       <init-param>           <param-name>contextConfigLocation</param-name>           <!--肯定要留神:咱们这里加载的是总的配置文件，之前被这里坑了！-->           <param-value>classpath:applicationContext.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>   <!--encodingFilter-->   <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>/*</url-pattern>   </filter-mapping>   <!--Session过期工夫-->   <session-config>       <session-timeout>15</session-timeout>   </session-config></web-app>

spring-mvc.xml编写

<?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   https://www.springframework.org/schema/mvc/spring-mvc.xsd">   <!-- 配置SpringMVC -->   <!-- 1.开启SpringMVC注解驱动 -->   <mvc:annotation-driven />   <!-- 2.动态资源默认servlet配置-->   <mvc:default-servlet-handler/>   <!-- 3.配置jsp 显示ViewResolver视图解析器 -->   <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">       <property name="viewClass" value="org.springframework.web.servlet.view.JstlView" />       <property name="prefix" value="/WEB-INF/jsp/" />       <property name="suffix" value=".jsp" />   </bean>   <!-- 4.扫描web相干的bean -->   <context:component-scan base-package="com.kuang.controller" /></beans>

最初的最初，大整合

applicationContext.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"      xsi:schemaLocation="http://www.springframework.org/schema/beans       http://www.springframework.org/schema/beans/spring-beans.xsd">   <import resource="spring-dao.xml"/>   <import resource="spring-service.xml"/>   <import resource="spring-mvc.xml"/></beans>

接下来就是自在的编写Controller以及视图层了，这里就不写了

本我的项目次要是基于狂神说的SpringMVC整合书城我的项目编写，额定的就是试了下PageHelper的插件，实现了分页
