项目从mysql迁移到oracle报错

本来没有一点错误，迁移之后出现了很多，不知道哪位大神见过下面的问题：
17:23:54,967 ERROR BasicPropertyAccessor:118 - IllegalArgumentException in class: com.ebupt.dataWarehouse.entity.dataQualityMonitoring.MonTaskConEntity, setter method of property: TemporaryIId
17:23:54,995 ERROR BasicPropertyAccessor:122 - expected type: int, actual value: java.math.BigDecimal

17:23:55,073 ERROR MonitoringTaskConfigurationAction:54 - org.hibernate.PropertyAccessException: IllegalArgumentException occurred while calling setter of com.ebupt.dataWarehouse.entity.dataQualityMonitoring.MonTaskConEntity.TemporaryIId

DAO层的相关函数是这样写的：
public List getMonTaskConList() throws Exception {
Session session = sessionFactory.openSession();
String sql = "SELECT d1.domain_id TemporaryIId, "
+ "d1.job_id TemporaryId, "
+ "d1.job_name job_name, "
+ "d1.is_effective is_effective, "
+ "d1.object_type object_type, "
+ "d1.object_name object_name, "
+ "d1.object_ename object_ename, "
+"d1.object_location object_location ,"
+"d1.time_field time_field, "
+ "COUNT(d2.rule_id) columnNum "
+ "from dq_conf_jobs d1, dq_conf_rule d2 "
//+ "where (d1.job_id = d2.job_id OR d1.job_id not in (SELECT job_id from dq_conf_rule)) AND d2.is_effective = '1'"
//+ "where ((d1.job_id = d2.job_id AND d1.domain_id = d2.domain_id) OR d1.job_id not in (SELECT job_id from dq_conf_rule)) AND d2.is_effective = '1'"
+ "where d1.job_id = d2.job_id OR d1.job_id not in (SELECT job_id from dq_conf_rule)"
//-- + "GROUP BY d1.job_id";
//非聚合函数字段都要在group by里面好像
+ "GROUP BY d1.job_id,d1.domain_id,d1.job_name,d1.is_effective,d1.object_type,d1.object_name,d1.object_ename,d1.object_location,d1.time_field";
//String sql = "";
try {
Query query = session.createSQLQuery(sql)
.addScalar("TemporaryIId")
.addScalar("TemporaryId")
.addScalar("job_name")
.addScalar("object_type")
.addScalar("object_name")
.addScalar("is_effective")
.addScalar("object_ename")
.addScalar("object_location")
.addScalar("time_field")
.addScalar("columnNum", Hibernate.INTEGER)
.setResultTransformer(Transformers.aliasToBean(MonTaskConEntity.class));
List resultList = query.list();
//查询rule总数，进行过滤
String countSql = "SELECT COUNT(*) FROM dq_conf_rule";
Query countQuery = session.createSQLQuery(countSql);
int count = ((Number) countQuery.uniqueResult()).intValue();
//数据整理，id.job_id的赋值，如果rule行数为总行数，则表明该job并没有rule
if (resultList != null && resultList.size() > 0) {
for (MonTaskConEntity entity : resultList) {
if (entity.getColumnNum() == count) {
entity.setColumnNum(0);
}
MonTaskConEntityId idEntity = new MonTaskConEntityId();
idEntity.setJob_id(entity.getTemporaryId());
idEntity.setDomain_id(entity.getTemporaryIId());
entity.setId(idEntity);

}
}
return resultList;

} catch (Exception e) {
log.error(e);
throw e;
} finally {
session.close();
}

}
目的是把表格的数据获取显现出来
谢谢大家

解决方案

好像是 数据库数据类型跟java实体类的数据类型不一致， IllegalArgumentException in class: com.ebupt.dataWarehouse.entity.dataQualityMonitoring.MonTaskConEntity, setter method of property: TemporaryIId 这一句最重要，大体意思是说 com.ebupt.dataWarehouse.entity.dataQualityMonitoring.MonTaskConEntity 类中 的 TemporaryIId 属性 setter 方法 发生了 IllegalArgumentException（ 违反参数类型） ，最好 你应该看一下hibernatezh注解或者配置文件是否与数据库匹配

解决方案二：

数据库迁移后，数据字段类型不同数据库会有一些区别，你的程序有没有跟着调整

解决方案三：

oracle与mysql在语法和类型有一些不一样的，

解决方案四：

字段类型的问题，还有可能是你这个自动生成或者是别的问题

解决方案五：

expected type: int, actual value: java.math.BigDecimal
类型不对

解决方案六：

项目报错一
