原因：java.lang.NullPointerException
... 48多
我已经检查了PropertyAccessException的可能原因，如安全检查失败、getter或setter方法内部发生异常、可为空的数据库列映射到基元类型属性、Hibernate类型不可强制转换为属性类型（反之亦然）但仍然无法找出此错误的确切原因。此错误的主要原因是原始类型数据类型c_gps_antennae（类型为char）在数据库中映射为空值。由于原语不能为null，因此不能将其映射到可为null的列 查询数据库中的c_gps_天线返回如下
select c_gps_antennae from v4stock.tbl_model;
c_gps_antennae
----------------
(6 rows)
<property name="c_gps_antennae" type="char" length="1">
<column name="C_GPS_ANTENNAE" length="1"></column>
</property>
同样的事情也发生在我身上，我刚刚添加了一个新的列
<property name="c_gps_antennae" type="char" length="1">
<column name="C_GPS_ANTENNAE" length="1"></column>
</property>
