如何解决：使用JdbcTemplate.queryRowMapper;Ljava / util / List;容易受到SQL注入的攻击使用Spring JDBC

编程问答 2022-06-09

问题描述

完全错误：

This use of org/springframework/jdbc/core/JdbcTemplate.query
(Ljava/lang/String;Lorg/springframework/jdbc/core/RowMapper;)Ljava/util/List; 
can be vulnerable to sql injection (with Spring JDBC)

这是原因/解决方案：

The input values included in sql queries need to be passed in safely. 
Bind variables in prepared statements can be used to easily mitigate the risk of sql injection.

这是我的查询

 StringBuilder query = new StringBuilder();
 query.append("SELECT * from Events EVNT")
      .append(" WHERE EVNT.Roll IN ( '5','1') AND EVNTDemo.Roll is null ")
      .append(" AND date(EVNT.Updt) between ")
      .append("date('").append(getTMyDate()) .append("') AND  CURRENT DATE-10 DAY")

如何分配“？”到我的查询，并将整个where条件作为参数对象传递。还有其他方法可以解决此SONARQUBE问题

  final Object[] args = new Object[] {.....}
  result = jdbcTemplate.query(query,args,new MyMapper());

编辑1：

StringBuilder query = new StringBuilder();
 query.append("SELECT * from Events EVNT")
      .append(" WHERE EVNT.Roll IN ( '5','1') AND EVNTDemo.Roll is null ")
      .append(" AND date(EVNT.Updt) between ")
      .append("date('").append("?").append("') AND  CURRENT DATE-10 DAY")

  final Object[] args = new Object[]{getTs()}; 
  result = jdbcTemplate.query(query,new MyMapper());

我得到“？”附加在查询中，我在哪里出错？任何人都可以指出
