解決JDBC連接MySQL時發出的警告WARN: Establishing SSL connection without server's identity verification ...

Fri Mar 30 14:55:35 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.

仔細看了看，發現是字符串中沒有配置SSL這個配置項。

需要在連接字符串中加上useSSL=false/true配置。

但是我是在XML中配置，配置如下：

<?xml version="1.0" encoding="UTF-8"?>
<c3p0-config>
<!-- 這是默認配置信息 -->
<default-config> 
<!-- 連接四大參數配置 -->
<property name="jdbcUrl">jdbc:mysql://localhost:3306/somebodyblog?characterEncoding=utf8</property>
<property name="driverClass">com.mysql.jdbc.Driver</property>
<property name="user">root</property>
<property name="password">123456789</property>
<!-- 池參數配置 -->
<property name="acquireIncrement">3</property>
<property name="initialPoolSize">10</property>
<property name="minPoolSize">2</property>
<property name="maxPoolSize">10</property>
</default-config>

</c3p0-config>

在字符串后面加上&useSSL=false后發現eclipse會報錯！！！

啟動后變成這樣：

 

 

 

這是為什么呢？？？？

於是搜尋資料發現：

在XML中，包括HTML中，要顯示&這個字符，必須對其轉義轉義！！

遂改稱如下樣子：

 

 

 

貼出來：jdbc:mysql://localhost:3306/somebodyblog?characterEncoding=utf8&amp;useSSL=false
