test:

@Test
    public void SpringMybatis(){
        ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext("spring.xml");
        UserDao userdao = context.getBean(UserDao.class);
        UserEntity user1 = userdao.findUserById(20l);
        UserEntity user2 = userdao.findUserById(20l);
        System.out.println(user1);
        System.out.println(user2);
        System.out.println(user1==user2);

    }

result:

UserEntity(id=20, name=zhengziye,.... createdAt=null, updatedAt=null)
UserEntity(id=20, name=zhengziye, .....createdAt=null, updatedAt=null)
false

Break point debugging:
Conclusion: It is found that their two queries are not called by the same executor, which means that they are not the same session, and the executor and session are one-to-one, and the first-level cache only works in the same session , so the first-level cache is invalid
