tomcat链接mysql时超时报错java.io.EOFException: Can not read response from server. Expected to read 4 bytes,

需要在配置文件里加上下面就ok了

<property name=”minEvictableIdleTimeMillis” value=”1800000″ />

<property name=”numTestsPerEvictionRun” value=”3″ />

<property name=”testOnBorrow” value=”true” />

<property name=”testWhileIdle” value=”true” />

<property name=”testOnReturn” value=”true” />

<property name=”validationQuery” value=”SELECT 1″ />
