tomcat jdbc pool高級配置

開啓PoolSweeper

tomcat-jdbc-8.5.11-sources.jar!/org/apache/tomcat/jdbc/pool/PoolProperties.java

@Override
    public boolean isPoolSweeperEnabled() {
        boolean timer = getTimeBetweenEvictionRunsMillis()>0;
        boolean result = timer && (isRemoveAbandoned() && getRemoveAbandonedTimeout()>0);
        result = result || (timer && getSuspectTimeout()>0);
        result = result || (timer && isTestWhileIdle() && getValidationQuery()!=null);
        result = result || (timer && getMinEvictableIdleTimeMillis()>0);
        return result;
    }

參數

spring.datasource.tomcat.max-active=100
spring.datasource.tomcat.max-idle=50
