一、介绍
1、简介
- JDBC 连接池：应用从池里借/还连接，而不是每次请求都新建/关闭连接。
- 特点：高性能（"zero-overhead"）、体积小（约 165KB）、配置简单、被 Spring Boot 2.x/3.x 选为默认连接池。
- 设计：极简配置、时间单位统一为毫秒、不做 Statement 缓存（建议用驱动自带缓存）。
二、集成方式和应用
1、集成方式
只要引入了 spring-boot-starter-jdbc（或带 JDBC 的 starter），Spring Boot 会：
- 自动使用 HikariCP 作为 DataSource 实现；
- 根据配置自动创建 HikariDataSource Bean，不需要再单独加 HikariCP 依赖。
2、连接池参数
如果不配置数据库连接池的参数，默认如下：
| 参数 | 默认值 | 说明 |
|---|---|---|
| maximum-pool-size | 10 | 连接池最大连接数 |
| minimum-idle | 与 maximum-pool-size 相同（即 10） | 最少保留的空闲连接数 |
| connection-timeout | 30000（30 秒） | 从池中获取连接的最长等待时间，超时抛异常 |
| idle-timeout | 600000（10 分钟） | 空闲连接超过该时间可被回收 |
| max-lifetime | 1800000（30 分钟） | 连接在池中的最大存活时间 |
| pool-name | 自动生成（如 "HikariPool-1"） | 未配置时由 HikariCP 自动命名 |
示例：
spring.datasource.primary.db.jdbc-url=jdbc:mysql://xxx?autoReconnect=true&useAffectedRows=true&characterEncoding=UTF-8&allowMultiQueries=true&rewriteBatchedStatements=true
spring.datasource.primary.db.driver-class-name=com.mysql.cj.jdbc.Driver

spring.datasource.slaver.mybatis-plus.configuration.patch_account_condition=true
spring.datasource.slaver.mybatis-plus.configuration.log-impl=org.apache.ibatis.logging.nologging.NoLoggingImpl3、代码里怎么用
- 常规用法：注入 DataSource，正常做 JDBC / MyBatis 等操作即可，底层就是 HikariCP。
- 要查池状态：若当前 Bean 是 HikariCP（或被包装了一层），可以 unwrap(HikariDataSource.class) 后取 HikariPoolMXBean，就像你项目里的 PoolTestController 那样。

3、日志配置
（1）ConnectionPoolLoggingDataSource
package com.example.dbpooldemo.config;
import com.zaxxer.hikari.HikariDataSource;

import java.util.concurrent.atomic.AtomicLong;
/**
* DataSource 包装器：每次 getConnection 时打印耗时 + 连接池状态（active/idle/total/threadsAwaiting），
* 便于证明"连接池满时其他请求需等待连接"。
*/
public class ConnectionPoolLoggingDataSource implements DataSource {
private static final Logger log = LoggerFactory.getLogger(ConnectionPoolLoggingDataSource.class);
private final DataSource delegate;
private final long slowThresholdMs;
private final boolean logEveryGet;
private final String poolName;
private final AtomicLong connectionGetCounter = new AtomicLong(0);
public ConnectionPoolLoggingDataSource(DataSource delegate, long slowThresholdMs, boolean logEveryGet) {
this.delegate = delegate;
this.slowThresholdMs = slowThresholdMs;
this.logEveryGet = logEveryGet;

}
private static String resolvePoolName(DataSource ds) {

}

}
@Override
public Connection getConnection() throws SQLException {

long seq = connectionGetCounter.incrementAndGet();
try {
Connection conn = delegate.getConnection();
long cost = System.currentTimeMillis() - start;
afterGetConnection(cost, seq);
return conn;
} catch (SQLException e) {
long cost = System.currentTimeMillis() - start;
log.warn("[DB连接] getConnection 失败, 等待耗时={}ms, poolName={}, seq={}, thread={}", cost, poolName, seq, threadName(), e);
throw e;
}
}
@Override
public Connection getConnection(String username, String password) throws SQLException {
long start = System.currentTimeMillis();

log.warn("[DB连接] getConnection 失败, 等待耗时={}ms, poolName={}, seq={}, thread={}", cost, poolName, seq, threadName(), e);
throw e;
}
}
private void afterGetConnection(long costMs, long seq) {
PoolStats stats = getPoolStats();
boolean slow = costMs >= slowThresholdMs;

}
}
private PoolStats getPoolStats() {
if (!(delegate instanceof HikariDataSource)) {
return PoolStats.NA;
}
HikariPoolMXBean pool = ((HikariDataSource) delegate).getHikariPoolMXBean();
if (pool == null) {
return PoolStats.NA;
}
return new PoolStats(pool.getActiveConnections(), pool.getIdleConnections(), pool.getTotalConnections(), pool.getThreadsAwaitingConnection());

}
static final PoolStats NA = new PoolStats(-1, -1, -1, -1);
}
}作用：对真正的 DataSource（例如 HikariCP）做一层包装，实现 DataSource 接口。
做的事：
- 每次有人调 getConnection() 时，先记一下时间，再转给里面的真实 DataSource 拿连接。
- 根据"拿连接耗时"和配置决定是否打日志：
- 耗时 ≥ slow-threshold-ms → 打 WARN（拿连接过慢）。
- 若开启了"每次拿连接都打日志"，再打 INFO，内容里带上：等待耗时、poolName、active/idle/total/threadsAwaiting、seq、线程名。
目的：方便你看"每次 SQL 用连接"的耗时和当时连接池状态，用来验证连接池满时请求在等连接。
（2）DataSourceLoggingConfig
package com.example.dbpooldemo.config;
import org.springframework.beans.BeansException;
import org.springframework.beans.factory.config.BeanPostProcessor;
import org.springframework.boot.autoconfigure.condition.ConditionalOnProperty;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import javax.sql.DataSource;
/**
* 将容器中的 DataSource 包装为带"获取连接耗时 + 连接池状态"日志的 DataSource。
*/
@Configuration
public class DataSourceLoggingConfig {
@Bean
@ConditionalOnProperty(name = "spring.datasource.logging.enabled", havingValue = "true", matchIfMissing = false)
public BeanPostProcessor dataSourceLoggingBeanPostProcessor(DataSourceLoggingProperties properties) {
return new BeanPostProcessor() {
@Override
public Object postProcessAfterInitialization(Object bean, String beanName) throws BeansException {
if (bean instanceof DataSource && !(bean instanceof ConnectionPoolLoggingDataSource)) {
return new ConnectionPoolLoggingDataSource(
(DataSource) bean,
properties.getSlowThresholdMs(),
properties.isLogEveryGet()
);
}
return bean;
}
};
}
@Bean
@ConditionalOnProperty(name = "spring.datasource.logging.enabled", havingValue = "true")
public DataSourceLoggingProperties dataSourceLoggingProperties() {
return new DataSourceLoggingProperties();
}
@ConfigurationProperties(prefix = "spring.datasource.logging")
public static class DataSourceLoggingProperties {
/** 超过该耗时(ms)打 WARN：拿到连接过慢 */
private long slowThresholdMs = 500;
/** true=每次 getConnection 都打 INFO（含等待耗时+池状态），便于证明连接池满时请求在等连接 */
private boolean logEveryGet = false;
public long getSlowThresholdMs() {
return slowThresholdMs;
}
public void setSlowThresholdMs(long slowThresholdMs) {
this.slowThresholdMs = slowThresholdMs;
}
public boolean isLogEveryGet() {
return logEveryGet;
}
public void setLogEveryGet(boolean logEveryGet) {
this.logEveryGet = logEveryGet;
}
}
}作用：Spring 配置类，负责"把上面的包装套到数据源上"和"读配置"。
做的事：
- 定义一个 BeanPostProcessor：在 Spring 容器里，等真正的 DataSource（如 HikariCP）创建好后，用 ConnectionPoolLoggingDataSource 把它包一层，之后整个应用拿到的就是带日志的 DataSource。
- 定义一个 DataSourceLoggingProperties：从 spring.datasource.logging.* 读 slow-threshold-ms、log-every-get、enabled 等，并只在 spring.datasource.logging.enabled=true 时注册上面这个 Processor 和包装。
目的：不写死在代码里，通过配置开关和参数控制"是否打拿连接日志、多慢算慢、是否每次拿连接都打"。
4、启动类

import org.springframework.boot.SpringApplication;
