基于common-pool实现jdbc连接对象池化
基于common-pool实现jdbc连接对象池化：
主要解决方式通用性资源型实例池化管理，便于统一创建，资源监控及资源释放
主要分为三部分:
对象获取标识：DataSourceAccount
对象池工厂类：ConnectionPoolFactory
k-v对象池：GenericKeyedObjectPool
连接标识key：DataSourceAccount
/** * @ClassName DataSource.java * @author liangxiaohui * @version 1.0.0 * @Description */ public class DataSourceAccount { private String url; private String username; private String passsword; private String host; private String port; private String dbName; private String dbType; private final String gp_url="jdbc:postgresql://%s:%s/%s"; private final String mysql_url="jdbc:mysql://%s:%s/%s"; private final String hive_url="hive2://%s:%s/%s"; public String getUrl() { if("gp".equals(dbType)){ return String.format(gp_url,host,port,dbName); }else if("mysql".equals(dbType)){ return String.format(mysql_url,host,port,dbName); }else if("hive".equals(dbType)){ return String.format(hive_url,host,port,dbName); }else{ throw new IllegalArgumentException("参数异常"); } } public String getUsername() { return username; } public String getHost() { return host; } public void setHost(String host) { this.host = host; } public String getPort() { return port; } public void setPort(String port) { this.port = port; } public String getDbName() { return dbName; } public void setDbName(String dbName) { this.dbName = dbName; } public void setUsername(String username) { this.username = username; } public String getPasssword() { return passsword; } public void setPasssword(String passsword) { this.passsword = passsword; } @Override public int hashCode() { return (getUrl()+username+passsword).hashCode(); } @Override public boolean equals(Object obj) { if(this==obj){ return true; } if(null==obj){ return false; } DataSourceAccount objt=(DataSourceAccount)obj; if((getUrl()+username+passsword).equals(objt.getUrl()+objt.getUsername()+objt.getPasssword())){ return true; } return false; } public String getDbType() { return dbType; } public void setDbType(String dbType) { this.dbType = dbType; } }
对象池工厂类：ConnectionPoolFactory （内部类）（关于连接驱动：该示例没有通过class.forName显式手动加载到内存中（只通过maven引用依赖），但经测试依然可用，能够正常被注册）
网上资料：
JDBC 4.0的特性
得益于Mustang中的Java SE 服务提供商机制，Java开发人员再也不必用类似Class.forName() 的代码注册JDBC驱动来明确加载JDBC。
当调用DriverManager.getConnection()方法时，DriverManager类将 自动设置合适的驱动程序。该特性向后兼容，因此无需对现有的JDBC代码作任何改动。
DriverManager类源码中的原因注释（源代码62-65行）：
* <P>Applications no longer need to explicitly load JDBC drivers using <code>Class.forName()</code>. Existing programs * which currently load JDBC drivers using <code>Class.forName()</code> will continue to work without * modification. *
