paip.hibernate list 返回位null的解决
但是size是对的...
里面都是null...
hb3.2版本...oracle11g
＝＝＝＝＝＝＝＝＝原因：没主键
也许没主键,看累挂,真的没...
走加上...在myeclipse生成...走ok兰...发现生成的pojo和没主键的时候儿也不一样...

// fields
private long id;
private long vdnid;
private long userid;
private long confkbstypepid;
private long departmentid;
private long grpsubsitepid;
private string question;
private string keyword;
private string answer;
private long belong;
// property accessors
@genericgenerator(name = generator, strategy = increment)
@id
@generatedvalue(generator = generator)
@column(name = id, unique = true, nullable = false, precision = 22, scale = 0)
public long getid() {
return this.id;
}
要是没主键,走弄个..
// fields
private tconfkbsid id;
// property accessors
@embeddedid
@attributeoverrides( {
@attributeoverride(name = vdnid, column = @column(name = vdnid, precision = 22, scale = 0)),
@attributeoverride(name = userid, column = @column(name = userid, precision = 22, scale = 0)),
@attributeoverride(name = confkbstypepid, column = @column(name = confkbstypepid, precision = 22, scale = 0)),
@attributeoverride(name = departmentid, column = @column(name = departmentid, precision = 22, scale = 0)),
@attributeoverride(name = grpsubsitepid, column = @column(name = grpsubsitepid, precision = 22, scale = 0)),
@attributeoverride(name = id, column = @column(name = id, precision = 22, scale = 0)),
@attributeoverride(name = question, column = @column(name = question, length = 2048)),
@attributeoverride(name = keyword, column = @column(name = keyword, length = 2048)),
@attributeoverride(name = answer, column = @column(name = answer, length = 1096)),
@attributeoverride(name = belong, column = @column(name = belong, precision = 22, scale = 0)) })
public tconfkbsid getid() {
return this.id;
}

hibernate 查询视图返回list为null的解决方法 2013-01-08 16:12:37
分类： linux
hibernate查询视图时，会将视图的所有字段作为主键，如果存在为空字段则返回值就为空，也就查询不到相应的结果。myeclipse反转工具生成的实体包含两个表，一个表是entpriwarqueryid，一个表是entpriwarquery，处理方法如下：
1.把此表entpriwarquery当做普通的表处理，增加主键及主键生成策略，还有相关的get和set方法，也就是说把该表处理成普通的实体；
2.在创建视图时把可能为空的字段做处理，forexampl：
case when p.fileno is null then '0'
else p.fileno
end as fileno,
是为空的字段有值即可；
