讲解SSM的xml文件

概述：这些配置文件很烦，建议直接复制粘贴

springMVC.xml文件

  1. <?xml version="1.0" encoding="UTF-8"?>

  80.     <!-- 实现注解的声明式事务 -->
  81.     <tx:annotation-driven transaction-manager="transactionManager" mode="proxy"/>

在这个文件中就已经配置了sqlSessionFactory、MapperScannerConfigurer 。

一个用来与数据库进行交互的，一个用来扫描包的。

项目结构：

然后配置一下jdbc.properties

  1. druid.driverClassName=com.mysql.cj.jdbc.Driver
  2. druid.url=jdbc:mysql://127.0.0.1:3306/cyl?useSSL=false&allowPublicKeyRetrieval=true&serverTimezone=UTC
  3. druid.username=root
  4. druid.password=123456
  5. druid.initialSize=10
  6. druid.minIdle=6
  7. druid.maxActive=50
  8. druid.maxWait=60000
