小编mra*_*ley的帖子

我有一个嵌入密钥的实体.实体只有键作为字段,键有7个字段,其中一些可以为空.

当我运行以下查询时:

Criteria criteria = session.createCriteria(getPersistentClass());
criteria.add(Restrictions.eq("id.profPropertyId", profileExtensionName));
Object obj = criteria.list();
log.info(obj);
return (List<ProfileExtensions>) obj; 

我得到了正确的结果数,但每个结果都是null(即我得到4000个空对象的列表).我尝试过使用HQL查询和标准,但它们都给出了相同的结果.

映射类是从现有数据库生成的.

为查询生成的SQL如下所示

select this_.PROF_DATA_TYPE as PROF1_14_0_, this_.PROF_EXT_KEY as PROF2_14_0_, 
       this_.PROF_KEY as PROF3_14_0_, this_.PROF_NAME as PROF4_14_0_, 
       this_.PROF_PROPERTY_ID as PROF5_14_0_, this_.PROF_VALUE as PROF6_14_0_, 
       this_.PROF_VALUE_EXTENDED as PROF7_14_0_ 
from EMPINST.PROFILE_EXTENSIONS this_ 
where this_.PROF_PROPERTY_ID=?

看起来它应该返回正确的数据.

映射文件非常简单(并从模式生成:

我正在尝试将get_url模块用于ansible,当我运行它时,我收到以下错误:

failed: [localhost] => (item=10) => {"failed": true, "item": "10"}
msg: httplib2 is not installed

现在我已经使用pip成功安装了httplib2:

pip install httplib2
Requirement already satisfied (use --upgrade to upgrade): httplib2 in /usr/local/lib/python2.7/site-packages

但显然这对情况没有帮助.我可以看到ansible使用的是与操作系统(安装了httplib2)不同的PYTHON_PATH,但我无法弄清楚如何将httplib2安装到该路径中(除了复制它不好).

任何帮助都非常感谢.
