首先查了错误代码对应的问题是 -103 42604 无效数学文字,但是没有找到错误！最后找同事帮忙查看，原因出在sql语句上！
错误语句:

String sql = "select t.rule_code as ruleCode,t.run_time as runTime,t.err_code as errCode,t.err_msg as errMsg from  code_rep_rule_log t where t.rule_code="+ruleCode+" and t.run_time="+runTime+"";

修改后

String sql = "select t.rule_code as ruleCode,t.run_time as runTime,t.err_code as errCode,t.err_msg as errMsg from  code_rep_rule_log t where t.rule_code='"+ruleCode+"' and t.run_time='"+runTime+"'";

因为数据库表中对应的字段是varchar类型的，需要用单引号引起来！
