1简介

分为Spring SpringMVC Mybatis 三部分 , [ Spring:替换创建对象的操作,servlet->service ] [ mybatis:持久化保存数据,控制bean->数据库 ] [ springMVC :主要是控制请求,交给DispatcherServlet 然后在渲染视图]

2思路

1首先是创建环境 ,创建完了 ,编写对应的bean dao service controller ,当然了推荐使用Mybatis反向生成工具(贼高效 方便简单) 不会的看之前的博客 https://blog.csdn.net/weixin_45434902/article/details/109494420 末尾部分 2 然后生成完毕,

3 开始你的业务,思路(我这里使用mapscanner可以省略dao的实现类

: 1 先在service接口里面生命方法 2然后在impl里面实现它 (调用dao,dao调用mapper映射)

3 在页面里面发送请求,然后在controller里面接收,然后controller调用service方法,service调用dao,dao调用mapper,然后逐层返回给controller,controller再返回给页面

注意:增删改查上面一定要加 事务注解 @Transactional

3 我常用的依赖:

1 pom的

2mybatis的

<?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.zx.bean"></package> </typeAliases> <plugins> <!-- PageHelper4.1.6 --> <plugin interceptor="com.github.pagehelper.PageHelper"> <property name="dialect" value="mysql"/> </plugin> </plugins> </configuration>

3springde (需要在resource下创建mapper文件夹 为了省略dao的实现类,注解用mapperscanner扫描指定mapper包下的所有mapper,而不扫描别的mapper)

<?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:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" 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/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd" > <!-- 八件事--> <!-- 1配置数据源--> <bean id="db" class="com.alibaba.druid.pool.DruidDataSource"> <property name="driverClassName" value="com.mysql.jdbc.Driver"></property> <property name="url" value="jdbc:mysql://localhost:3306/test?useUnicode=true&amp;characterEncoding=utf-8"></property> <property name="username" value="root"></property> <property name="password" value="root"></property> </bean> <!-- 2创建sqlsessionfactory工厂--> <bean id="fac" class="org.mybatis.spring.SqlSessionFactoryBean"> <property name="dataSource" ref="db"></property> <property name="configLocation" value="classpath:mybatis.xml"></property> <property name="mapperLocations" value="classpath:mapper/*.xml"></property> </bean> <!-- 3创建MapperScannerConfigurer来 省略dao的实现类impl--> <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"> <property name="sqlSessionFactoryBeanName" value="fac"></property> <property name="basePackage" value="com.zx.dao"></property> </bean> <!-- 4配置事务--> <bean id="tx" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> <property name="dataSource" ref="db"></property> </bean> <!-- 5启用MVC注解--> <mvc:annotation-driven></mvc:annotation-driven> <!-- 6配置视图解析器--> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="suffix" value=".jsp"></property> <property name="prefix" value="/"></property> </bean> <!-- 7扫描注解包 @controller @service可以使用--> <context:component-scan base-package="com.zx"></context:component-scan> <!-- 8配置静态资源访问--> <mvc:default-servlet-handler></mvc:default-servlet-handler> </beans>

4web.xml的(默认好像为为2.3, 一定改为2.5)

<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" version="2.5"> <display-name>Archetype Created Web Application</display-name> <!--配置前端控制器:--> <servlet> <servlet-name>aa</servlet-name> <servlet-class> org.springframework.web.servlet.DispatcherServlet </servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring.xml</param-value> </init-param> </servlet> <servlet-mapping> <servlet-name>aa</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> <!-- 处理post乱码--> <filter> <filter-name>bb</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>bb</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> </web-app>

5 log4j的

<?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.zx.bean"></package> </typeAliases> <plugins> <!-- PageHelper4.1.6 --> <plugin interceptor="com.github.pagehelper.PageHelper"> <property name="dialect" value="mysql"/> </plugin> </plugins> </configuration>

5 mybatis-generator的(需要在resource下创建mapper文件夹 为了省略dao的实现类,注解用mapperscanner扫描指定mapper包下的所有mapper,而不扫描别的mapper)

<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE generatorConfiguration PUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN" "http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd"> <!-- 配置生成器 --> <generatorConfiguration> <!--数据库驱动jar --> <classPathEntry location="/Volumes/mydata/Maven/apache-maven-3.6.3/my_repository/mysql/mysql-connector-java/5.1.38/mysql-connector-java-5.1.38.jar" /> <context id="MyBatis" targetRuntime="MyBatis3"><!--去除注释 --> <commentGenerator> <property name="suppressAllComments" value="true" /> </commentGenerator> <!--数据库连接 --> <jdbcConnection driverClass="com.mysql.jdbc.Driver" connectionURL="jdbc:mysql://localhost:3306/test" userId="root" password="root"> </jdbcConnection> <!--生成实体类 指定包名 以及生成的地址 （可以自定义地址，但是路径不存在不会自动创建 使用Maven生成在target目录下，会自动创建） --> <javaModelGenerator targetPackage="com.zx.bean" targetProject="/Volumes/mydata/IDEA/SSM/src/main/java"> <property name="trimStrings" value="true" /> </javaModelGenerator> <!--生成SQLmapper文件 --> <sqlMapGenerator targetPackage="mapper" targetProject="/Volumes/mydata/IDEA/SSM/src/main/resources"> </sqlMapGenerator> <!--生成Dao文件,生成接口 --> <javaClientGenerator type="XMLMAPPER" targetPackage="com.zx.dao" targetProject="/Volumes/mydata/IDEA/SSM/src/main/java"> </javaClientGenerator> <table tableName="bills" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"> </table> <table tableName="billtype" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"> </table> <table tableName="subject" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"> </table> </context> </generatorConfiguration>
