Druid源码分析(四) 从连接池获取数据库链接getConnectionDirect()

public DruidPooledConnection getConnectionDirect(long maxWaitMillis) throws SQLException {

// 超时重试次数,达到这个值就报错

int notFullTimeoutRetryCnt = 0

for () {

// handle notFullTimeoutRetry

DruidPooledConnection poolableConnection

try {

// 核心逻辑

poolableConnection = getConnectionInternal(maxWaitMillis)

} catch (GetConnectionTimeoutException ex) {

if (notFullTimeoutRetryCnt <= this.notFullTimeoutRetryCount &&!isFull()) {

notFullTimeoutRetryCnt++

if (LOG.isWarnEnabled()) {

LOG.warn("get connection timeout retry : " + notFullTimeoutRetryCnt)

}

continue

}

throw ex

}

1.pom.xml

2.yml文件配置

3.访问

启动项目，访问druid管理页面- localhost:8080/druid/login.html,登录的用户名和密码，我在yml配置成test，所以用test登录就行，登录后页面如下：
