在JDBC连接Mysql数据库的过程中出现了如下的警告信息:
警告1:
Thu Aug 30 10:58:30 CST 2018 WARN: Establishing SSL connection without server's identity verification is not recommended.
According to MySQL 5.5.45+, 5.6.26+ and 5.7.6+ requirements SSL connection must be established by default if explicit
option isn't set. For compliance with existing applications not using SSL the verifyServerCertificate property is set
to 'false'. You need either to explicitly disable SSL by setting useSSL=false, or set useSSL=true and provide
truststore for server certificate verification.
是Mysql数据库的SSL连接问题,提示警告不建议使用没有带服务器身份验证的SSL连接,是在MYSQL5.5.45+, 5.6.26+ and 5.7.6+版本中才有的这个问题。解决办法在警告中已经说明了
1.在数据库连接的url中添加useSSL=false;
2.url中添加useSSL=true,并且提供服务器的验证证书。
警告2:
XML Parser Error on line 15: 对实体 "characterEncoding" 的引用必须以 ';' 分隔符结尾。
<!-- 数据库连接信息:驱动类、连接地址、用户名、密码 -->
<jdbcConnection driverClass="com.mysql.cj.jdbc.Driver"
connectionURL="jdbc:mysql://localhost:3306/test?serverTimezone=UTC&characterEncoding=utf8&useSSL=false"
userId="root" password="123456">
</jdbcConnection>
