SSM—CRUD
一、环境搭建
1、开发环境
IDE:idea 2022.2
构建工具:maven 3.8.4
MySQL版本:MySQL 8.0.28
MyBatis版本:MyBatis 3.5.10
2、准备工作
2.2.1、创建maven工程
① 打包方式:war
② 引入依赖
<properties> <spring.version>5.3.22</spring.version> </properties> <dependencies> <!-- Spring --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-beans</artifactId> <version>${spring.version}</version> </dependency> <!-- SpringMVC --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-web</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-jdbc</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-aspects</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-test</artifactId> <version>${spring.version}</version> </dependency> <!-- MyBatis核心 --> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis</artifactId> <version>3.5.10</version> </dependency> <!-- MyBatis和Spring的整合包 --> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis-spring</artifactId> <version>2.0.6</version> </dependency> <!-- 连接池 --> <dependency> <groupId>com.alibaba</groupId> <artifactId>druid</artifactId> <version>1.2.9</version> </dependency> <!-- Junit测试 --> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.13.2</version> <scope>test</scope> </dependency> <!-- MySQL驱动 --> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>8.0.28</version> </dependency> <!-- log4j日志 --> <dependency> <groupId>log4j</groupId> <artifactId>log4j</artifactId> <version>1.2.17</version> </dependency> <!-- PageHelper分页 --> <dependency> <groupId>com.github.pagehelper</groupId> <artifactId>pagehelper</artifactId> <version>5.3.0</version> </dependency> <!-- 日志 --> <dependency> <groupId>ch.qos.logback</groupId> <artifactId>logback-classic</artifactId> <version>1.2.11</version> </dependency> <!-- ServletAPI --> <dependency> <groupId>javax.servlet</groupId> <artifactId>javax.servlet-api</artifactId> <version>4.0.1</version> </dependency> <!-- JSON --> <dependency> <groupId>com.fasterxml.jackson.core</groupId> <artifactId>jackson-databind</artifactId> <version>2.13.2.2</version> </dependency> <!-- 文件上传 --> <dependency> <groupId>commons-fileupload</groupId> <artifactId>commons-fileupload</artifactId> <version>1.4</version> </dependency> <!-- Spring和Thymeleaf整合包 --> <dependency> <groupId>org.thymeleaf</groupId> <artifactId>thymeleaf-spring5</artifactId> <version>3.0.14.RELEASE</version> </dependency> </dependencies>
③ 创建表
二、搭建MyBatis环境
1、创建属性文件jdbc.properties
jdbc.driver=com.mysql.cj.jdbc.Driver jdbc.url=jdbc:mysql://localhost:3306/ssm_crud?serverTimezone=UTC jdbc.username=root jdbc.password=123456
2、创建MyBatis核心配置文件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> </configuration>
3、创建日志文件log4j.xml
<?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE log4j:configuration SYSTEM "log4j.dtd"> <log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/"> <appender name="STDOUT" class="org.apache.log4j.ConsoleAppender"> <param name="Encoding" value="UTF-8" /> <layout class="org.apache.log4j.PatternLayout"> <param name="ConversionPattern" value="%-5p %d{MM-dd HH:mm:ss,SSS}%m (%F:%L) \n" /> </layout> </appender> <logger name="java.sql"> <level value="debug" /> </logger> <logger name="org.apache.ibatis"> <level value="info" /> </logger> <root> <level value="debug" /> <appender-ref ref="STDOUT" /> </root> </log4j:configuration>
三、配置Spring配置文件
<!-- 扫描组件(除控制层) --> <context:component-scan base-package="com.jingchao"> <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/> </context:component-scan> <!-- 引入jdbc.properties --> <context:property-placeholder location="classpath:jdbc.properties"/> <!-- 配置数据源 --> <bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource"> <property name="driverClassName" value="${jdbc.driver}"/> <property name="url" value="${jdbc.url}"/> <property name="username" value="${jdbc.username}"/> <property name="password" value="${jdbc.password}"/> </bean> <!-- 配置事务管理器 --> <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> <property name="dataSource" ref="dataSource"/> </bean> <!-- 开启事务的注解驱动 --> <tx:annotation-driven transaction-manager="transactionManager"/> <!-- 配置SqlSessionFactoryBean,可以直接在Spring的IOC中获取SqlSessionFactory --> <bean class="org.mybatis.spring.SqlSessionFactoryBean"> <!-- 设置MyBatis核心配置文件的路径 --> <property name="configLocation" value="classpath:mybatis-config.xml"/> <!-- 设置数据源 --> <property name="dataSource" ref="dataSource"/> <!-- 设置类型别名所对应的包 --> <property name="typeAliasesPackage" value="com.jingchao.entity"/> <!-- 设置映射文件的位置,只有当映射文件和接口的包名不一致的情况才设置 --> <!-- <property name="mapperLocations" value="classpath:mapper/*.xml"/> --> <!-- 配置插件 --> <!-- <property name="plugins"> <array> <bean class="com.github.pagehelper.PageInterceptor"/> </array> </property> --> </bean> <!-- 配置mapper接口的扫描,可以将指定包下面的所有mapper接口通过SqlSession创建代理实现类对象,并将这些对象交给IOC容器管理 --> <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"> <property name="basePackage" value="com.jingchao.mapper"/> </bean>
四、配置SpringMVC配置文件
<!-- 扫描控制层组件 --> <context:component-scan base-package="com.jingchao.controller"/> <!--配置视图解析器--> <bean id="viewResolver" class="org.thymeleaf.spring5.view.ThymeleafViewResolver"> <property name="order" value="1"/> <property name="characterEncoding" value="UTF-8"/> <property name="templateEngine"> <bean class="org.thymeleaf.spring5.SpringTemplateEngine"> <property name="templateResolver"> <bean class="org.thymeleaf.spring5.templateresolver.SpringResourceTemplateResolver"> <!-- 视图前缀 --> <property name="prefix" value="/WEB-INF/templates/"/> <!-- 视图后缀 --> <property name="suffix" value=".html"/> <property name="templateMode" value="HTML5"/> <property name="characterEncoding" value="UTF-8" /> </bean> </property> </bean> </property> </bean> <!-- 配置默认的servlet处理静态资源 --> <mvc:default-servlet-handler/> <!-- 开启mvc的注解驱动 --> <mvc:annotation-driven/> <!-- 配置视图控制器 --> <mvc:view-controller path="/" view-name="index"/> <!-- 配置文件上传的解析器 --> <bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver"/>
五、配置web.xml
1、添加web.xml
File ——> Project Structure
2、配置web.xml
<!-- 配置Spring的编码过滤器 --> <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> <init-param> <param-name>forceEncoding</param-name> <param-value>true</param-value> </init-param> </filter> <filter-mapping> <filter-name>CharacterEncodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <!-- 配置处理请求方式的过滤器 --> <filter> <filter-name>HiddenHttpMethodFilter</filter-name> <filter-class>org.springframework.web.filter.HiddenHttpMethodFilter</filter-class> </filter> <filter-mapping> <filter-name>HiddenHttpMethodFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <!-- 配置SpringMVC的前端控制器 --> <servlet> <servlet-name>DispatcherServlet</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <!-- 设置SpringMVC配置文件自定义位置和名称 --> <init-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:springmvc.xml</param-value> </init-param> <!-- 将DispatcherServlet的初始化时间提前到服务器启动时 --> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>DispatcherServlet</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> <!-- 配置Spring的监听器,在服务器启动时加载Spring的配置文件 --> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <!-- 设置Spring配置文件自定义的位置和名称 --> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring.xml</param-value> </context-param>
六、开发前端页面
在WEB-INF下新建文件夹templates,然后新建index.html,使用bootstrap快速搭建前端页面,前端页面使用的资源如下:
bootstrap-3-4-1-dist
axios.min.js
vue.js
jquery-2.2.4.min.js
前端使用vue和bootstrap完成
七、后端实现
项目使用Rest风格展现,分页使用分页插件pagehelper
