    DataSource dataSource;
    @Test
    void contextLoads() throws SQLException {
        System.out.println(dataSource.getClass());

        Connection connection = dataSource.getConnection();
        System.out.println(connection);

    }

}

here is my application.yml

spring:
  datasource:
    username: root

    url: jdbc:mysql://localhost:3306/mybatis?useSSL=false&useUnicode=true&characterEncoding=UTF-8&allowPublicKeyRetrieval=true
    driver-class-name: com.mysql.cj.jdbc.Driver

I confirmed that my username is root and my pwd is 011575.And also open the mysql service, please help me!!

CodePudding user response：

When springboot reads the data in yml, it will read the pure digital data starting with the number 0 in binary, octal or decimal, and the read value will be different from the original stored value.

so just change your application.yml like this:

password: "011575"

CodePudding user response：

The username and password should be like this

username: root
password: "011575"
