本文整理了Java中org.hibernate.criterion.Example类的一些代码示例，展示了Example类的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Example类的具体详情如下：
包路径：org.hibernate.criterion.Example
类名称：Example

Example介绍

[英]Support for query by example.

List results = session.createCriteria(Parent.class) 
.add( Example.create(parent).ignoreCase() ) 
.createCriteria("child") 
.add( Example.create( parent.getChild() ) ) 
.list();

"Examples" may be mixed and matched with "Expressions" in the same Criteria.
[中]支持通过示例进行查询

List results = session.createCriteria(Parent.class) 
.add( Example.create(parent).ignoreCase() ) 
.createCriteria("child") 
.add( Example.create( parent.getChild() ) ) 
.list();

“示例”可能与相同条件下的“表达式”混合匹配。

代码示例

代码示例来源：origin: hibernate/hibernate-orm

t = s.beginTransaction();
Master m1 = (Master) s.createCriteria(Master.class)
  .add( Example.create(m).enableLike().ignoreCase().excludeProperty("bigDecimal") )
  .uniqueResult();
assertTrue( m1.getOtherMaster()==m1 );
assertTrue( m1==null );
m1 = (Master) s.createCriteria(Master.class)
  .add( Example.create(m).excludeProperty("bigDecimal") )
  .createCriteria("otherMaster")
    .add( Example.create(m).excludeZeroes().excludeProperty("bigDecimal") )
  .uniqueResult();
assertTrue( m1.getOtherMaster()==m1 );
Master m2 = (Master) s.createCriteria(Master.class)
  .add( Example.create(m).excludeNone().excludeProperty("bigDecimal") )
  .uniqueResult();
assertTrue( m2==m1 );
m.setName(null);
m2 = (Master) s.createCriteria(Master.class)
  .add( Example.create(m).excludeNone().excludeProperty("bigDecimal") )
  .uniqueResult();
assertTrue( null == m2 );
