jdbcTemplate的问题

[kunmingkunlun]

public Department getDep(int id){
String sql = "select * from department where id=?";
final Department dep = null;
final List list = null;
final Object[] params = new Object[]{id};
jdbcTemplate.query(sql, params, new RowCallbackHandler(){
public void processRow(ResultSet rs) throws SQLException {
if(rs.next()){
dep = new Department();//这儿出错了
dep.setId(rs.getInt("id"));
dep.setName(rs.getString("name"));
dep.setDetail(rs.getString("detail"));
}
}
});
return dep;
}
为什么 dep = new Department();这个地方出错啊？
我初衷是想在其他方法中判断这个Department 是不是为null，
该怎么做啊？谢谢了

Department dep = null;

不知道楼上是什么意思？

[FAT0708]

final Department dep = null;
改为Department dep = null;

[Quote=引用 3 楼 FAT0708 的回复:]
final Department dep = null;
改为Department dep = null;

但是方法里面不接受非final变量了啊

[yukang_ky]

final Department dep = null;
改为Department dep = null;
将变量声明为final,就意味者变量不能被重新赋值，只能维持原来的值，当你为final变量重新赋值时，就发生错误。
