CONSTRUCT查询保存列表结构（数据库中保存查询对象的数据集合）

CONSTRUCT查询保存列表结构（数据库中保存查询对象的数据集合）

如何解决CONSTRUCT查询保存列表结构？

我列出了以下三个元素：

<Employee#1> <hasOrderedTasks> [ a rdf:List ; rdf:first <FirstTask> ;
                                 rdf:rest [ rdf:first <SecondTask> ;
                                 rdf:rest [ rdf:first <ThirdTask> ;
                                 rdf:rest rdf:nil ] ] ] .

我的问题是：如何使用CONSTRUCT类型的查询返回列表（及其结构）？ 请注意，列表可能具有可变数量的元素，查询将需要对此进行概括。 我可以使用类似的东西：

CONSTRUCT {
 ?employee <hasOrderedTasks> ?list .
 ?list <hasElement> ?element 
 }
WHERE {
 ?employee <hasOrderedTasks> ?list .
 ?list rdf:rest*/rdf:first ?element .
 }

但是这会破坏我的列表顺序。我当然可以在子查询中使用一些聚合来计算列表中元素的索引，但是即使那样也不会按原样重新创建列表。 也许还有其他功能可以帮助我吗？还是在SPARQL中这是不可能的？

@PostConstruct方法上的@Transactional

@PostConstruct方法上的@Transactional

我想在应用程序开始时阅读文本数据装置（CSV文件），并将其放入数据库中。

为此，我创建了带有初始化方法（@PostConstruct批注）的PopulationService。

我也希望它们在单个事务中执行，因此我在同一方法上添加了@Transactional。

然而，@Transactional似乎被忽略：该交易启动/停止我的低水平DAO方法。

那我需要手动管理交易吗？

我想在应用程序开始时阅读文本数据装置（CSV文件），并将其放入数据库中。

为此，我创建了带有初始化方法（@PostConstruct批注）的PopulationService。

我也希望它们在单个事务中执行，因此我在同一方法上添加了@Transactional。

然而，@Transactional似乎被忽略：该交易启动/停止我的低水平DAO方法。

那我需要手动管理交易吗？在@PostConstruct中（与InitializingBean接口中的afterPropertiesSet一样），无法确保已完成所有后期处理，因此（实际上）不能有任何事务。确保工作正常的唯一方法是使用TransactionTemplate。

因此，如果你希望·在事务中执行某些操作，则必须执行以下操作：

@Service("something")public class Something {    @Autowired    @Qualifier("transactionManager")    protected PlatformTransactionManager txManager;    @PostConstruct    private void init(){        TransactionTemplate tmpl = new TransactionTemplate(txManager);        tmpl.execute(new TransactionCallbackWithoutResult() {            @Override            protected void doInTransactionWithoutResult(TransactionStatus status) {                //PUT YOUR CALL TO SERVICE HERE            }        });   }}

constructor Php 构造函数construct的前下划线是双的_

constructor Php 构造函数construct的前下划线是双的_

定义和用法

__construct() 函数创建一个新的 SimpleXMLElement 对象。

如果成功，则该函数返回一个对象。如果失败，则返回 false。

语法

__construct(data,options,is_url,ns,is_prefix)
登录后复制
参数 描述
data 必需。形式良好的 XML 字符串或 XML 文档的路径或 URL。
options 可选。规定附加的 Libxml 参数。
is_url 可选。规定 data 参数是否是 URL。默认是 false。
ns 可选。
is_prefix 可选。

返回值

返回一个表示数据的 SimpleXMLElement 对象。

例子

<?php $xmlstring = <<<XML
<?xml version="1.0" encoding="ISO-8859-1"?><note><to>George</to><from>John</from><heading>Reminder</heading>Don''t forget the meeting!
</note>
XML;

$xml = new <code>SimpleXMLElement($xmlstring)</code>;

echo $xml-&gt;body[0];
?&gt;
登录后复制

输出类似：

Don''t forget the meeting!<br>后来看construct的前_是一个，我靠，上次也是这个错误，忘了，现在记着了 <br>function __construct() <br>{} <br>不是 <br>function _construct() <br>{}
