1.解决了读取pub_init_all.sql文件乱码的问题(new String(b, "UTF-8");)   

2.解决多个sql语句分号隔开不能批量执行的问题(加 &allowMultiQueries=true)

private static final String RDSADDRESSIP = MessageManager.getMsg("rdsAddressIp");

private static final String DBINSTANCEID = MessageManager.getMsg("dbInstanceId");

private static final String ACCESSKEYID = MessageManager.getMsg("accessKeyId");

private static final String ACCESSSECRET = MessageManager.getMsg("accessSecret");

private static final String FORNAME = "com.mysql.jdbc.Driver";

@RequestMapping("/executeSql")
@ResponseBody
public Msg executeSql(HttpServletRequest request, String accountName, String dbName) throws Exception {
    String realPath = request.getSession().getServletContext().getRealPath("intSql/pub_init_all.sql");
    //通过jdbc执行sql文件
    File file=new File(realPath);
    byte[] b= FileCopyUtils.copyToByteArray(file);
    String sql = new String(b, "UTF-8");
    String res = JdbcUtil.executeSql(FORNAME, RDSADDRESSIP, PORT, dbName, accountName, accountName, sql);
    if (res.equals("success")) {
        return Msg.success().add("成功");
    }else {
        return Msg.fail().add("初始化sql执行失败");
    }

}
