SampleRepository.java类有如下所示的查询:
@Query("select eq from EmailQueue eq where eq.inquiry in (select issue.id from Inquiry issue where issue.id = eq.inquiry and systimestamp >= eq.sendDate + (1/24) * ?3 ) and "
+ " systimestamp >= eq.sendDate + (1/24) * ?2 and eq.sent
Scala定义了一个AnyRef类,这个类在编译后被解释为Java的Object类。但是,从语言的角度来看,AnyRef类并不完全等同于Object,因为它引入了几个新方法,例如eq(),它接受AnyRef并返回布尔值,然后比较引用的标识
如果Java中有一个类本身定义了具有不同结果类型的eq()方法,并且这个类实现的接口也具有此方法:
public interface I {
String eq(Object that);
}
public class A implements I {
public String eq(Object that) {return "&
当我们从下面的命令中得到多个PID (java.exe)时,请帮助我删除它:
echooff
for /F "tokens=2 delims=," %%G in ('tasklist /FI "imagename eq java.exe" /FI "modules eq service.dll" /NH /FO CSV') DO set str=%%G
set str=%str:~1,-1%
echo %str%
if not %str%==0 taskkill /pid %str% /f

我有一个文档{_id: abc, orderdate:(ISO date), quantity:10},我正在尝试用Java语言实现查询,我们可以搜索给定月份中quantity为> 5的所有文档,例如:select * from documents where month(orderdate)=Jan and quantity>5
你能帮我用Java写这个查询吗?
根据IEEE754Java,与任何数字进行相等比较都应该是假的( NaN和JavaScript语言都是如此)。但在下面的代码中,将javax scriptEngine用于JavaScript,将变量设置为NaN与其本身进行比较将返回true。
import javax.script.ScriptEngine;
import javax.script.ScriptEngineManager;
import javax.script.ScriptException;
public class Main {
public static void main(String[] args) t
环境:春季,JPA,Hibernate
我得到了这个Stacktrace (修改了类名):
Undeclared path 'fooPK'. Add this path as a source to the query to be able to reference it.; nested exception is java.lang.IllegalArgumentException: Undeclared path 'fooPK'. Add this path as a source to the query to be able to reference i
我在使用CASE WHEN THEN和EnumPath时遇到了问题
Expression<CampaignStatus> cases = new CaseBuilder().when(qCampaign.campaignStatus.gt(CampaignStatus.NOT_SENT)).then(CampaignStatus.ERROR);
(CampaignStatus是Enum)
最后,我想在请求更新中使用这个案例。
EnumExpression<CampaignStatus> cases = new CaseBuilder().when(qCampaign.c
AssignCoScholastic.java
@Entity
@Table(name="assignCoScholastic")
public class AssignCoScholastic

我有以下代码
public class UserDAO {
private final MongoCollection<Document> usersCollection;
private Random random = new SecureRandom();
public UserDAO(final MongoDatabase blogDatabase) {
usersCollection = blogDatabase.getCollection("users");
}

我正在用Mockito写一些测试。我有一个要测试的类,它基本上是通过AsyncTask将同步调用转换为异步调用。
这是要测试的类:
public class GetEntryImpl implements GetEntry {
private final DataEntryRepository mDataEntryRepository;
public GetEntryImpl() {
this(new DataEntryRepositoryImpl());
}
public GetEntryImpl(@NonNull final DataE
我想检查两个Java对象是否相等。此检查也应适用于数组。我写了以下内容:
/** Check if two Java objects are equal. */
private static <T> boolean equal (T a, T b)
{
if (a == null)
if (b == null)
return true;
else
if (b.getClass().isArray())
return Arrays.equals(b, a);
else
return b.equal
我有一个可以抛出多个异常的私有方法。我正在尝试为异常编写测试用例。下面的代码显示了两个测试用例。其中每一个,当单独运行时,都会成功,没有任何问题。但是,当整个测试类作为JUnit测试运行时,我会得到org.mockito.exceptions.misusing.UnfinishedStubbingException
下面是我的代码:
@RunWith(PowerMockRunner.class)
@PowerMockRunnerDelegate(SpringJUnit4ClassRunner.class)
@PrepareForTest(TestService.class)
public c
我有以下几点:
@Entity
public class Person {
@Id
private long id;
@Column
private String firstName;
// getters and setters
}
我想让以下几点发挥作用:
Criteria criteria = session.createCriteria(Person.class);
criteria.add(Restrictions.eq("firstName", "john"));
OR
criteria.
我正在使用Sharepoint SOAP服务来获取基于查询的数据。当我在GetListItems中将查询参数作为null传递时,我会得到一个文档列表,但当我传递查询时,它会给我以下错误消息。
javax.xml.ws.soap.SOAPFaultException: Exception of type 'Microsoft.SharePoint.SoapServer.SoapServerException' was thrown.

hibernate中有一个OneToMany关系,定义如下:
@Entity
@Table(name = "groups")
public class Group extends BaseModel {// BaseModel defines id as @Id and @GeneratedValue
@OneToMany
@JoinColumn(name = "group_id")
private List<User> users;
// other fields, getters and setters omi
