java 读取resource里的文件

InputStream fin = FlinkETL.class.getResourceAsStream("/dim_product_tag.sql");
InputStreamReader reader = new InputStreamReader(fin);
BufferedReader buffReader = new BufferedReader(reader);
String strSql = "";
String line = "";
strSql = buffReader.readLine();
while ((line = buffReader.readLine()) != null) {
    strSql = strSql + line + "

}

String[] sl = strSql.split(";");
for(int i=0;i<sl.length;i++){
    System.out.println("================");
    System.out.println(sl[i]);
    tEnv.executeSql(sl[i]);
