【字号: 日期:2023-09-04 09:40:49浏览:3作者:猪猪
1 框架组成

Spring

SpringMVC

MyBatis

2 所需工具

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

3 搭建步骤

3.1 新建一个空Maven项目,填写项目相关信息,完成

3.3 pom.xml导入依赖,设置Maven资源过滤

<!--导入依赖--><dependencies> <!--Junit--> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.12</version> </dependency> <!--数据库驱动--> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>8.0.15</version> </dependency> <!-- 数据库连接池 --> <dependency> <groupId>com.mchange</groupId> <artifactId>c3p0</artifactId> <version>0.9.5.2</version> </dependency> <!--Servlet - JSP --> <dependency> <groupId>javax.servlet</groupId> <artifactId>servlet-api</artifactId> <version>2.5</version> </dependency> <dependency> <groupId>javax.servlet.jsp</groupId> <artifactId>jsp-api</artifactId> <version>2.2</version> </dependency> <dependency> <groupId>javax.servlet</groupId> <artifactId>jstl</artifactId> <version>1.2</version> </dependency> <!--Mybatis--> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis</artifactId> <version>3.5.2</version> </dependency> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis-spring</artifactId> <version>2.0.2</version> </dependency> <!--Spring--> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>5.1.9.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-jdbc</artifactId> <version>5.1.9.RELEASE</version> </dependency> <!--lombok--> <dependency> <groupId>org.projectlombok</groupId> <artifactId>lombok</artifactId> <version>1.18.10</version> </dependency></dependencies><!--静态资源导出问题--><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>

3.4 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'/> </settings> <!--取别名--> <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>

3.5 编写database.properties(数据库配置文件)

jdbc.driver=com.mysql.cj.jdbc.Driverjdbc.url=jdbc:mysql://localhost:3306/数据库名?useSSL=true&useUnicode=true&characterEncoding=utf8jdbc.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

3.6 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 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 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 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 :https://www.cnblogs.com/jpfss/p/7799806.html--> <bean class='org.mybatis.spring.mapper.MapperScannerConfigurer'> <!-- 注入sqlSessionFactory --> <property name='sqlSessionFactoryBeanName' value='sqlSessionFactory'/> <!-- 给出需要扫描Dao接口包 --> <property name='basePackage' value='com.dao'/> </bean></beans>

3.7 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 class='com.service.ServiceImpl'> <property name='Mapper' ref='Mapper'/> </bean> <!-- 配置事务管理器 --> <bean class='org.springframework.jdbc.datasource.DataSourceTransactionManager'> <!-- 注入数据库连接池 --> <property name='dataSource' ref='dataSource' /> </bean></beans>

3.8 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>

3.9 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 https://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>

3.10 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>

3.11 配置Tomcat

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 先编写实体类(pojo) dao层:编写接口,接口对应mapper.xml(建议同名) service层:编写接口,编写接口实现类(创建dao层对象,返回调用dao层的操作) controller层:负责具体的业务模块流程的控制,在此层要调用service层的接口来控制业务流程 编写相应的jsp文件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
