單獨使用druid數據源

引入maven依賴

        <dependency>
            <groupId>com.alibaba</groupId>
            <artifactId>druid</artifactId>
            <version>1.1.21</version>
        </dependency>

編寫數據源配置文件

將配置文件放在項目根路徑下

driverClassName = com.mysql.jdbc.Driver
url = jdbc:mysql://domain/database
username = database-username
password = database-password

initialSize = 2
maxActive = 60
minIdle = 3
maxWait = 60000
removeAbandoned = true
removeAbandonedTimeout = 180
timeBetweenEvictionRunsMillis = 60000
minEvictableIdleTimeMillis = 300000
validationQuery = SELECT 1 FROM DUAL
testWhileIdle = true 
testOnBorrow = false
testOnReturn = false
poolPreparedStatements = true
maxPoolPreparedStatementPerConnectionSize = 50
filters = stat

獲取數據源對象

public class DBService {
    private DataSource dataSource;
    
    public  DBService() throws Exception{
        InputStream resourceAsStream = DBService.class.getClassLoader().getResourceAsStream("db.properties");
        Properties prop = new Properties();
        prop.load(resourceAsStream);
        DataSource dataSource = DruidDataSourceFactory.createDataSource(prop);
        this.dataSource = dataSource;
    }
}
