java小程序监控数据库

// 示例代码：配置HikariCP连接池
HikariConfig config = new HikariConfig();
config.setJdbcUrl("jdbc:mysql://localhost:3306/mydb");
config.setUsername("user");
config.setPassword("password");
config.setMaximumPoolSize(50); // 增加最大连接数
HikariDataSource dataSource = new HikariDataSource(config);

-- 示例代码：分析SQL查询效率
EXPLAIN SELECT * FROM users WHERE age > 30;
