Wed Apr 24 21:05:28 CST 2019 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.

这是在学习mybatis的加载属性文件测试时出现的问题

我的SqlMapConfig.xml文件:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE configuration
PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>

	<!-- 加载属性文件 -->
	<properties resource="db.properties"></properties>
	<!-- 和spring聚合后environments配置将废除 -->
	<environments default="development">
		<environment id="development">
			<!-- 使用jdbc事物管理 -->
			<transactionManager type="JDBC" />
			<!-- 数据库连接池 -->
			<dataSource type="POOLED">
				<property name="driver" value="${jdbc.driver}" />
				<!-- jdbc:mysql://localhost:3306/mybatis?useUnicode=true&amp;characterEncoding=utf-8&amp;useSSL=false&amp;serverTimezone=UTC -->
				<property name="url" value="${jdbc.url}" />
				<property name="username" value="${jdbc.username}" />
				<property name="password" value="${jdbc.password}" />

			</dataSource>
		</environment>
	</environments>

	<!-- 加载映射文件 -->
	<mappers>
		<mapper resource="sqlmap/User.xml" />
		<mapper resource="mapper/UserMapper.xml" />
	</mappers>

</configuration>

我的有问题的db.properties文件:

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/mybatis
jdbc.username=root
jdbc.password=mysql

上面的password是你自己的数据库密码

报错说明:不建议在没有服务器身份验证的情况下建立SSL连接。根据MySQL 5.5.45+, 5.6.26+和5.7.6+的要求,如果没有设置显式选项,则必须默认建立SSL连接。您需要通过设置useSSL=false显式地禁用SSL,或者设置useSSL=true并为服务器证书验证提供信任存储。创建连接错误 通信链路失败

解决办法:在MySQL的链接中添加useSSL=false

改db.properties文件为

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/mybatis?useSSL=false
jdbc.username=root
jdbc.password=mysql

这样就可以解决问题了
