阿里druid连接池监控数据自定义存储
如何将druid连接池监控到的sql执行效率，连接池资源情况等进行持久化存储，方便系统运维分析优化，以下案例初步测试成功。
第一部：
新建MyDruidStatLogger类实现接口 extends DruidDataSourceStatLoggerAdapter implements DruidDataSourceStatLogger,详细代码如下：本实例只实现接收消息并在控制台打印，实际业务应用需要具体实现存储方案。
package xxx; import com.alibaba.druid.support.logging.Log;
import com.alibaba.druid.support.logging.LogFactory;
import java.util.ArrayList;
import java.util.LinkedHashMap;

public MyDruidStatLogger(){
this.configFromProperties(System.getProperties());
}
@Override
public void configFromProperties(Properties properties) {
String property = properties.getProperty("druid.stat.loggerName");
if (property != null && property.length() > 0) {
setLoggerName(property);
}
}
public Log getLogger() {

} @Override
public void setLoggerName(String loggerName) {

}

} public boolean isLogEnable() {

}

map.put("dbType", statValue.getDbType());
map.put("name", statValue.getName());

}

}

} ArrayList<Map<String, Object>> sqlList = new ArrayList<Map<String, Object>>();
if (statValue.getSqlList().size() > 0) {
for (JdbcSqlStatValue sqlStat : statValue.getSqlList()) {
Map<String, Object> sqlStatMap = new LinkedHashMap<String, Object>();
sqlStatMap.put("sql", sqlStat.getSql()); if (sqlStat.getExecuteCount() > 0) {

} long executeErrorCount = sqlStat.getExecuteErrorCount();
if (executeErrorCount > 0) {
sqlStatMap.put("executeErrorCount", executeErrorCount);
} int runningCount = sqlStat.getRunningCount();
if (runningCount > 0) {
sqlStatMap.put("runningCount", runningCount);
} int concurrentMax = sqlStat.getConcurrentMax();
if (concurrentMax > 0) {
sqlStatMap.put("concurrentMax", concurrentMax);
} if (sqlStat.getFetchRowCount() > 0) {

} map.put("sqlList", sqlList);
} if (statValue.getKeepAliveCheckCount() > 0) {
map.put("keepAliveCheckCount", statValue.getKeepAliveCheckCount());
} String text = JSONUtils.toJSONString(map);
System.out.println("==============:"+text);
}
}
第二步：配置spring bean
<bean id="myStatLogger" class="com.andaily.web.context.MyDruidStatLogger"> </bean> <bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource" init-method="init" destroy-method="close">
<!-- 基本属性 url、user、password -->
<property name="url" value="${jdbc.url}" />
<property name="username" value="${jdbc.username}" />
<property name="password" value="${jdbc.password}" />
<!-- 配置初始化大小、最小、最大 -->
<property name="initialSize" value="1" />
<property name="minIdle" value="1" />
<property name="maxActive" value="20" />
<!-- 配置获取连接等待超时的时间 -->
<property name="maxWait" value="60000" />
<!-- 配置间隔多久才进行一次检测，检测需要关闭的空闲连接，单位是毫秒 -->
<property name="timeBetweenEvictionRunsMillis" value="60000" />
<!-- 配置一个连接在池中最小生存的时间，单位是毫秒 -->
<property name="minEvictableIdleTimeMillis" value="300000" />
<property name="validationQuery" value="SELECT 'x'" />
<property name="testWhileIdle" value="true" />
<property name="testOnBorrow" value="false" />
<property name="testOnReturn" value="false" />
<!-- 打开PSCache，并且指定每个连接上PSCache的大小 -->
<property name="poolPreparedStatements" value="true" />
<property name="maxPoolPreparedStatementPerConnectionSize" value="20" />
<!-- 配置监控统计拦截的filters，去掉后监控界面sql无法统计 -->
<property name="filters" value="stat" />
<property name="timeBetweenLogStatsMillis" value="1000" />
<property name="statLogger" ref="myStatLogger"/>
</bean>
启动后就可以看到控制台打印的durid监控信息了。
