本文整理了Java中org.hibernate.Query.setResultTransformer方法的一些代码示例，展示了Query.setResultTransformer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。Query.setResultTransformer方法的具体详情如下：
包路径：org.hibernate.Query
类名称：Query
方法名：setResultTransformer

Query.setResultTransformer介绍

[英]Set a strategy for handling the query results. This can be used to change "shape" of the query result.
[中]设置处理查询结果的策略。这可用于更改查询结果的“形状”。

代码示例

代码示例来源：origin: stackoverflow.com

Query query=session.createSQLQuery("your query");
query.setResultTransformer(AliasToEntityMapResultTransformer.INSTANCE);
List<Map<String,Object>> aliasToValueMapList=query.list();

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

hqlQuery.setResultTransformer( tupleTransformer  );

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

t = s.beginTransaction();
Query sqlQuery = s.getNamedQuery("EmploymentAndPerson");
sqlQuery.setResultTransformer(Transformers.ALIAS_TO_ENTITY_MAP);
list = sqlQuery.list();
assertEquals(1,list.size() );
t = s.beginTransaction();
sqlQuery = s.getNamedQuery( "organizationreturnproperty" );
sqlQuery.setResultTransformer( Transformers.ALIAS_TO_ENTITY_MAP );
list = sqlQuery.list();
assertEquals( 2,list.size() );

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

Transaction t = session.beginTransaction();
try {
  getSelectNewQuery( session ).setResultTransformer(Transformers.ALIAS_TO_ENTITY_MAP).list();
  fail("'select new' together with a resulttransformer should result in error!");
  getSelectNewQuery( session ).setResultTransformer(Transformers.ALIAS_TO_ENTITY_MAP).iterate();
  fail("'select new' together with a resulttransformer should result in error!");
  getSelectNewQuery( session ).setResultTransformer(Transformers.ALIAS_TO_ENTITY_MAP).scroll();
  fail("'select new' together with a resulttransformer should result in error!");
