(非原创,环境Play+Ebean ，新增加int 字段，出异常如下)

遇到一个奇怪的问题报错如下:

[error] application -

! @6og7253b0 - Internal server error, for (GET) [/] ->

不进入方法,查找资料发现问题出在数据库上.

javax.persistence.PersistenceException: org.hibernate.PropertyAccessException: Null value was assigned to a property of primitive type setter of......

原因：bean中新添加的字段是int类型

private int employeeid;@Column(name=calendar_employeeid)public intgetEmployeeId() {return employeeId;}public void setEmployeeId(int employeeId) {this.employeeId = employeeId;}

当数据库中该字段为null时，就会报错

解决方法1：该bean 中相应字段int 改为Integer

@Column(name=calendar_employeeid)public Integer getEmployeeId() {return employeeId;}public void setEmployeeId(Integer employeeId) {this.employeeId = employeeId;}

解决方法2：数据库中相应字段默认不为null
