public Dbdata getProp(String filePath) throws IOException {
Dbdata dbData = new Dbdata();
Properties props = new Properties();
InputStream ips = null;
ips = new BufferedInputStream(new FileInputStream(filePath));
props.load(ips);

ips.close();

// 将键值逐一从property中取出
if(props.getProperty("jdbc.driverClassName") != null) { //properties文件中有内容
String url = props.getProperty("jdbc.url");
String username = props.getProperty("jdbc.username");
String password = props.getProperty("jdbc.password");
String maxActive = props.getProperty("jdbc.maxActive");

dbData.setUserName(username);
dbData.setPass(password);
dbData.setMaxActive(maxActive);

String[] urlArr = url.split(":");
for(int i=0; i<urlArr.length; i++) {
if("mysql".equalsIgnoreCase(urlArr[i])) { //数据库是mysql
dbData.setDatabaseType(1);
//url="jdbc:mysql://localhost:3306/ngbstzq?zeroDateTimeBehavior=convertToNull";
dbData.setUrl(urlArr[2].substring(2));
String[] portDbname = urlArr[3].split("/");
dbData.setPort(portDbname[0]);
dbData.setDatabaseName(portDbname[1].split("//?")[0]);
break;
} else if("sqlserver".equalsIgnoreCase(urlArr[i])) { //数据库是sqlserver
dbData.setDatabaseType(2);
//url="jdbc:jtds:sqlserver://localhost:1433;databaseName=ngbstzq;SelectMethod=cursor";
dbData.setUrl(urlArr[3].substring(2));
String[] portDbname = urlArr[4].split(";");
dbData.setPort(portDbname[0]);
dbData.setDatabaseName(portDbname[1].split("=")[1]);
break;
}
}
}
return dbData;
}

其中properties文件格式如下：

jdbc.driverClassName = com.mysql.jdbc.Driver
jdbc.url = jdbc:mysql://localhost:3306/ngbstzq?zeroDateTimeBehavior=convertToNull
jdbc.username = root
jdbc.password = 123
jdbc.maxActive = 20
