2023学年完整公开课版SSM整合

SSM整合如何进行SSM框架整合？SpringMVC与Spring之间不存在整合的问题，只涉Spring与MyBatis的整合，以及SpringMVC与MyBatis的整合。1整合思路SSM框架整合图：如果前台页面查询出的数据，则三大框架整合成功。如何确定SSM框架整合成功？1整合思路aopalliance-1.0.jaraspectjweaver-1.8.10.jarspring-aop-4.3.6.RELEASE.jarspring-aspects-4.3.6.RELEASE.jarspring-beans-4.3.6.RELEASE.jarspring-context-4.3.6.RELEASE.jarspring-core-4.3.6.RELEASE.jarspring-expression-4.3.6.RELEASE.jarspring-jdbc-4.3.6.RELEASE.jarspring-tx-4.3.6.RELEASE.jar1.Spring框架所需的JAR包4个核心模块JARAOP开发使用的JARJDBC和事务的JAR注意：核心容器依赖的commons-logging的JAR在MyBatis的lib包中！2准备所需JAR包ant-1.9.6.jarant-launcher-1.9.6.jarasm-5.1.jarcglib-3.2.4.jarcommons-logging-1.2.jarjavassist-3.21.0-GA.jarlog4j-1.2.17.jarlog4j-api-2.3.jarlog4j-core-2.3.jarmybatis-3.4.2.jarognl-3.1.12.jarslf4j-api-1.7.22.jarslf4j-log4j12-1.7.22.jar2.MyBatis框架所需的JAR包核心JAR解压mybatis，lib中的所有JAR2准备所需JAR包mybatis-spring-1.3.1.jar3.MyBatis与Spring整合包mysql-connector-java-5.1.40-bin.jar4.数据库驱动JAR（MySQL）commons-dbcp2-2.1.1.jarcommons-pool2-2.4.2.jar5.数据源所需JAR（DBCP）2准备所需JAR包2准备所需JAR包

根据上述整合需求，SSM框架整合所需要的基本JAR包如下图所示：jdbc.driver=com.mysql.jdbc.Driverjdbc.url=jdbc:mysql://localhost:3306/mybatisjdbc.username=rootjdbc.password=rootjdbc.maxTotal=30jdbc.maxIdle=10jdbc.initialSize=5perties创建Web项目，导入JAR包，并发布到类路径下。1创建一个名为config的源文件夹，创建数据库常量配置文件perties、Spring配置文件applicationContext.xml，以及mybatis-config.xml、springmvc-config.xml。23编写配置文件<context:property-placeholderlocation="classpath:perties"/><beanid="dataSource"class="mons.dbcp2.BasicDataSource"><propertyname="driverClassName"value="${jdbc.driver}"/>...</bean><beanid="transactionManager"class="org.springframework.jdbc.datasource.DataSourceTransactionManager"><propertyname="dataSource"ref="dataSource"/></bean> <tx:annotation-driventransaction-manager="transactionManager"/><beanid="sqlSessionFactory"class="org.mybatis.spring.SqlSessionFactoryBean"><propertyname="dataSource"ref="dataSource"/><propertyname="configLocation"value="classpath:mybatis-config.xml"/></bean><beanclass="org.mybatis.spring.mapper.MapperScannerConfigurer"><propertyname="basePackage"value=".sict.dao"/></bean><context:component-scanbase-package=".sict.service"/>3编写配置文件applicationContext.xml数据源配置配置事务管理器开启事务注解配置MyBatis工厂配置mapper文件扫描器Service层注解扫描<?xmlversion="1.0"encoding="UTF-8"?><!DOCTYPEconfigurationPUBLIC"-////DTDConfig3.0//EN""/dtd/mybatis-3-config.dtd"><configuration> <typeAliases> <packagename=".sict.po"/> </typeAliases></configuration>3编写配置文件mybatis-config.xml

在web.xml中，配置Spring的文件监听器、编码过滤器以及SpringMVC的前端控制器等信息。44整合应用测试基于SSM框架查询客户信息。publicclassCustomer{ privateIntegerid;//主键id privateStringusername;//客户名称

privateStringjobs;//职业

privateStringphone;//电话

//..省略getter/setter方法}4整合应用测试

在src目录下，创建.sict.po包，并在包中创建持久化类Customer：1package.sict.dao;import.sict.po.Customer;publicinterfaceCustomerDao{ publicCustomerfindCustomerById(Integerid);}4整合应用测试CustomerDao.java

在src目录下，创建一个.sict.dao包，创建接口CustomerDao以及映射文件CustomerDao.xml：2<?xmlversion="1.0"encoding="UTF-8"?><!DOCTYPEmapperPUBLIC"-////DTDMapper3.0//EN""/dtd/mybatis-3-mapper.dtd"><mappernamespace=".sict.dao.CustomerDao"><selectid="findCustomerById"parameterType="Integer"resultType="Customer"> select*fromt_customerwhereid=#{id}</select></mapper>4整合应用测试CustomerDao.xmlpackage.sict.service;import.sict.po.Customer;publicinterfaceCustomerService{ publicCustomerfindCustomerById(Integerid);}4整合应用测试

在src目录下，创建.sict.service包，创建接口CustomerService：3@Service@TransactionalpublicclassCustomerServiceImplimplementsCustomerService{ //注解注入CustomerDao @Autowired privateCustomerDaocustomerDao; //查询客户

publicCustomerfindCustomerById(Integerid){ returnthis.customerDao.findCustomerById(id); }}4整合应用测试

创建一个.sict.service.impl包，创建实现类CustomerServiceImpl：4@ControllerpublicclassCustomerController{ @Autowired privateCustomerServicecustomerService; @RequestMapping("/findCustomerById") publicStringfindCustomerB
