原创: spring boot5 与 mysql8 正确连接

首次spring boot 配置 ，测试通过jdbc ，连接mysql8.0.1 

 

 

1:pom.xml

    <dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
            <version>8.0.11</version>
        </dependency>

2:application.yml

spring:
  datasource:
　　#注意下行比不是mysql8.0多一个cj.
    driver-class-name: com.mysql.cj.jdbc.Driver
    username: root
    password: 123456
    url: jdbc:mysql://localhost:3306/recruit_gather?useUnicode=true&characterEncoding=UTF-8&serverTimezone=UTC&useSSL=false

3:测试类代码

import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;

import javax.sql.DataSource;
import java.sql.Connection;
import java.sql.SQLException;

@SpringBootTest
class SpringDataJdbc06ApplicationTests {
    @Autowired
    DataSource dataSource;
    @Test
    void contextLoads() throws SQLException {
        System.out.println("*******************");
        System.out.println(dataSource.getClass());
        Connection connection = dataSource.getConnection();
        System.out.println("connection连接:"+connection);
    }

}
