Spring
SpringMVC
MyBatis
Mysql 8.0.15
数据库管理系统,创建数据库
Tomcat 8.5.51
用于部署web项目
Maven 3.6.1
项目构建、项目依赖管理
lombok 1.18.10(可用可不用工具)
用于类注解创建setter、getter、无参构造、全参构造、toString等函数
注:只导入依赖,不安装插件是不起作用的
(1)新建一个空Maven项目,填写项目相关信息,完成
(2)添加web框架支持
选择现有框架支持
(3)pom.xml导入依赖,设置Maven资源过滤
<!--导入依赖-->

<includes>
<include>**/*.properties</include>
<include>**/*.xml</include>
</includes>
<filtering>false</filtering>

(4)编写MyBatis-config.xml(核心配置文件)
<?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>
<!--设置运行日志-->
<settings>
<setting name="logImpl" value="STDOUT_LOGGING"/>

<typeAliases>
<package name="com.pojo"/>
</typeAliases>
<!--绑定mapper,根据自己的项目设置-->
<mappers>
<mapper resource="com/dao/Mapper.xml"/>
</mappers>
</configuration>
(5)编写database.properties(数据库配置文件)
jdbc.driver=com.mysql.cj.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/数据库名?useSSL=true&useUnicode=true&characterEncoding=utf8
jdbc.username=数据库用户名
jdbc.password=数据库密码
根据自己的MySQL以及项目实际使用的数据库来修改设置
注:MySQL8.0以上驱动得使用com.mysql.cj.jdbc.Driver
(6)编写Spring-dao.xml(Spring整合MyBatis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: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 不能自动连接
c3p0 自动化操作(自动的加载配置文件 并且设置到对象里面)
-->
<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连接池的私有属性 -->
<property name="maxPoolSize" value="30"/>
<property name="minPoolSize" value="10"/>
<!-- 关闭连接后不自动commit -->
<property name="autoCommitOnClose" value="false"/>
<!-- 获取连接超时时间 -->
<property name="checkoutTimeout" value="10000"/>
<!-- 当获取连接失败重试次数 -->
<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,动态实现Dao接口注入到spring容器中 -->
<!--解释 :http://www.cnblogs.com/jpfss/p/7799806.html-->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<!-- 注入sqlSessionFactory -->
<property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/>
<!-- 给出需要扫描Dao接口包 -->
<property name="basePackage" value="com.dao"/>
</bean>
</beans>
(7)编写Spring-service.xml(Spring整合service层)
<?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相关的bean -->
<context:component-scan base-package="com.service" />
<!--ServiceImpl注入到IOC容器中,此处需要修改成自己的-->
<bean id="ServiceImpl" class="com.service.ServiceImpl">
<property name="Mapper" ref="Mapper"/>
</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>
(8)修改web.xml文件
<?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>
<!--一定要注意:我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过期时间-->
<session-config>
<session-timeout>15</session-timeout>
</session-config>
</web-app>
(9)编写Spring-mvc.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">
<!-- 配置SpringMVC -->
<!-- 1.开启SpringMVC注解驱动 -->
<mvc:annotation-driven />
<!-- 2.静态资源默认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" />
<!--此处注意路径问题,/WEB-INF/jsp/-->
<property name="prefix" value="/WEB-INF/jsp/" />
<property name="suffix" value=".jsp" />
</bean>
<!-- 4.扫描web相关的bean -->
<context:component-scan base-package="com.controller" />
</beans>
(10)编写applicationContext.xml(Spring配置整合文件)
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd">
<!--将Spring其他配置文件整合到一个总的配置文件,用的时候使用这个配置文件-->
<import resource="classpath:Spring-service.xml"/>
<import resource="classpath:Spring-dao.xml"/>
<import resource="classpath:Spring-mvc.xml"/>
</beans>
(11)配置Tomcat
(12)检查项目结构(左上角 文件 -> 项目结构)
(13)最后的项目文件结构
到了这里,框架已经搭建完成
4.接口对应的Mapper.xml
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper
PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<!--绑定对应的接口-->
<mapper namespace="com.dao.Mapper">
<!--此处写对应的SQL操作-->
</mapper>
5.功能添加步骤
6.建议
框架搭建完成后应写个简单的功能测试框架环境有无问题
