The server time zone value '�й���ʱ��' is unrecognized or represents more than one time zone.
介绍
再使用spring操作mysql数据库报错
@Test
public void test() {
try {
//创建连接池,先使用spring框架内置的连接池
DriverManagerDataSource dataSource =new DriverManagerDataSource();
//数据库驱动程序
dataSource.setDriverClassName("com.mysql.cj.jdbc.Driver");
//数据库连接字符串
dataSource.setUrl("jdbc:mysql://localhost:3306/demo");
//账号
dataSource.setUsername("root");
//密码
dataSource.setPassword("root");
//创建模板类
JdbcTemplate jdbcTemplate=new JdbcTemplate(dataSource);
//完成数据的添加
int res = jdbcTemplate.update("insert into s_user (age,name) values (?,?)",22,"测试人员");
} catch (Exception e) {
e.printStackTrace();
}
}
报错信息如下:
org.springframework.jdbc.CannotGetJdbcConnectionException: Failed to obtain JDBC Connection; nested exception is java.sql.SQLException: The server time zone value '�й���ʱ��' is unrecognized or represents more than one time zone. You must configure either the server or JDBC driver (via the serverTimezone configuration property) to use a more specifc time zone value if you want to utilize time zone support.

解决办法如下
复制区
jdbc:mysql://localhost:3306/demo?serverTimezone=UTC
虽然上面加上时区程序不出错了,但是我们在用java代码插入到数据库时间的时候却出现了问题。
比如在java代码里面插入的时间为:2017-08-21 17:29:56
但是在数据库里面显示的时间却为:2017-08-21 09:29:56
因为时区设置的问题。
UTC代表的是全球标准时间 ,但是我们使用的时间是北京时区也就是东八区,领先UTC八个小时。
UTC + (+0800) = 本地(北京)时间
完美解决方法
url的时区使用中国标准时间。也是就 serverTimezone=Asia/Shanghai
复制区
jdbc:mysql://localhost:3306/demo?useUnicode=true&characterEncoding=UTF-8&serverTimezone=Asia/Shanghai
