使用JDBC实现Oracle或PostgreSQL等数据库的数据源动态切换

1. 首先创建一个连接的Model类

public class JDBC_CONN { private String base_driver; private String base_url; private String base_name; private String base_pass; public String getBase_driver() { return base_driver; } public void setBase_driver(String base_driver) { this.base_driver = base_driver; } public String getBase_url() { return base_url; } public void setBase_url(String base_url) { this.base_url = base_url; } public String getBase_name() { return base_name; } public void setBase_name(String base_name) { this.base_name = base_name; } public String getBase_pass() { return base_pass; } public void setBase_pass(String base_pass) { this.base_pass = base_pass; } } public class JDBC_CONN { privat
