springboot3整合mybaitis plus动态数据源报错：Property ‘sqlSessionFactory‘ or ‘sqlSessionTemplate‘ are required

mybaitis plus 是国内苞米豆团队开发维护的，而springboot3作为最新的springboot版本，兼容性总有些问题，报上面错误，基本确定就是版本互相不兼容导致的，困扰我一天，直接上解决方案：

1 pom文件；注意数据源配置 和启动stater都是spring-boot3；

2 yaml配置文件

server:
  port: 8081
spring:
  application:
    name: dynamic-datasource
  datasource:
    dynamic:
      datasource:
        mssql_db:
          driver-class-name: com.mysql.cj.jdbc.Driver
          url: jdbc:mysql://xxxx:3506/registerreward?useUnicode=true&characterEncoding=utf8&useSSL=false&serverTimezone=Asia/Shanghai&tinyInt1isBit=false
          username: xxx
          password: xxxx
        mysql_db:
          driver-class-name: com.mysql.cj.jdbc.Driver
          url: jdbc:mysql://xxxx:3306/dbs_pv?useUnicode=true&characterEncoding=utf8&useSSL=false&serverTimezone=Asia/Shanghai&tinyInt1isBit=false
          username: xxx
          password: xxxxx
      primary: mssql_db
      strict: false
 
mybatis-plus:
  mapper-locations: classpath:mappers/*.xml
  configuration:
    log-impl: org.apache.ibatis.logging.stdout.StdOutImpl

最后 排除自动装配数据源即可，这注解是为了排除springboot的自动配置，有的项目可以不加，所以，根据自己的实际情况添加。

@SpringBootApplication(exclude = {DataSourceAutoConfiguration.class})

总结; mybaitis plus相关的问题 ，极大可能就是版本冲突问题，遇到问题就往他们官网社区看问题即可，不必怀疑自己写错了，极大概率是框架本身问题。希望该文能对你有帮助。
