sql语法检测

maven配置：

        <dependency>
            <groupId></groupId>
            <artifactId>jsqlparser</artifactId>
            <version>4.2</version>
        </dependency>

用 jsqlparser可以限定输入哪种DML sql语句，如只限定select查询语句，用执行计划可以校验sql语法错误，如下：

    public SqlCheckRspVo sqlCheck(SqlCheckReqVo sqlCheckReqVo) {
        SqlCheckRspVo sqlCheckRspVo = new SqlCheckRspVo();
        if(!().contains("$")){
           return new SqlCheckRspVo(false,"sql中没有添加$");
        }
        (().trim());
        if(().endsWith(";")){
            (().substring(0,().length()-1));
        }
        for( tableInfo : ()) {
            String sql = ().replace("$",());
            sqlCheckRspVo = sqlparse(sql);
            if(() == false){
                return  sqlCheckRspVo;
            }
            SqlSession sqlSession = null;
            PreparedStatement pst ;
            try {
                sqlSession = getNativeSqlSession();
                Connection dbCon = ();
                pst = ("explain plan for " +sql);
                ();
                ();
            } catch (SQLException e) {
                (false);
                ((e));
                return  sqlCheckRspVo;
            } finally {
                if (null != sqlSession) {
                    closeNativeSqlSession(sqlSession);
                }
            }
        }
        return  sqlCheckRspVo;
    }

    public SqlCheckRspVo sqlparse(String sqlContent){
        SqlCheckRspVo sqlCheckRspVo = new SqlCheckRspVo();
        try {
            Statement parse = (sqlContent);
            if(parse instanceof Select){
                (true);
            }else{
                (false);
                ("只能输入select语句");
            }
        }catch (Exception e){
            (false);
            ((e));
        }
        return sqlCheckRspVo;
    }
