我想模拟一个类的实例,该类在其单元测试期间在其构造函数中加载bean。问题是Spring在测试期间没有活动。
我的代码是:
public class foo{ //the tested class
ObjectA oa;
public foo(){
oa = SpringService.EnumInstance.LoadOa(); //uses spring to load oa
}
}
public ObjectA{ //that is an enum
ENUM_INSTANCE;
void func1(){...}
int func2(){.
我正在处理包含字符串的文本文件。
ligand_types A C Cl NA OA N SA HD # ligand atom types
我需要检查字符串中的模式:A、C、Cl、NA、OA、N、SA、HD,如果没有,则添加遗漏的"SA“和/或"HD”。
样本输入:
ligand_types A C Cl NA OA N HD # ligand atom types
ligand_types A C NA OA N SA # ligand atom types
ligand_types A C Cl NA OA N # l
我正在为Yesod应用程序进行OAuth2身份验证,而且我有一个类型错误,我真的不明白。目前,代码已被破坏,我还抛出了一些:: IO ()和undefined的代码,以帮助我隔离类型错误,但相关代码如下:
getAccessToken :: Manager -> OAuth2 -> ExchangeToken -> IO (OAuth2Result Errors OAuth2Token)
getAccessToken manager oa code = do
let (uri, defaultBody) = accessTokenUrl oa code
let bo
我需要关于优化我的功能的帮助/建议。如何避免重复这段代码:
select 1 from order_attr oa
where oa.order_id = o.order_id and ea.order_attr_name = 'administrationId'
下面是我的PL/SQL函数(这是一个示例,在实际代码中-片段多次重复):
begin
select count (distinct o.order_id)
into :result
from orders o
where o.ext_order_id = :ExtOrde
我有一些具有这个一般结构的代码:
interface Func<A> {
double apply(Optional<A> a);
}
class Foo {
public double compute(Func<Double> f) {
// Sometimes amend the function to do something slightly different
Func<Double> g = f;
if (someCondition())
g =
在Scala中的函数编程的练习中,我为Option实现了一个Traverse实例:
override def traverse[G[_],A,B](oa: Option[A])(f: A => G[B])(implicit G: Applicative[G]):
G[Option[B]] =
oa match {
case None => G.unit(None)
case _ => {
val a: A = oa.get
val x: G[B] = f(a)
G.
我有以下问题:-
Select
PUB.oa_inthed.adcode As Address_Code,
PUB.oa_intnom."due-date" As Commitment_Due_Date,
PUB.oa_inthed.company As Company,
PUB.oa_intnom.costcentre As Cost_Code,
PUB.oa_inthed.currency As Currency,
PUB.oa_inthed.description As Description,
PUB.oa_inthed.docdate As
我有以下XML: <oa:Parties>
<ow-o:SupplierParty>
<oa:PartyId>
<oa:Id>1</oa:Id>
</oa:PartyId>
</ow-o:SupplierParty>
<ow-o:CustomerParty>
<oa:PartyId>
<oa:Id>123-123</oa:Id> // I NEED THIS
</oa:PartyId>
在SSMS 2012中,我将看到在MS中创建的一个大视图。当我将视图脚本到查询窗口时,FROM子句如下所示:
FROM dbo.oa_projecttask_type RIGHT OUTER JOIN
dbo.oa_project_task RIGHT OUTER JOIN
dbo.[Functional Area] RIGHT OUTER JOIN
dbo.oa_category ON dbo.[Functional Area].[Product Code] = dbo.oa_category.name RIGHT OUTER JOIN
dbo
我只使用存储过程对db执行任何操作。我不想使用ORB,在你说:)
对于每个表,我都有一个相应的DAO类(VB或C#),例如:
Namespace Dao
Public Class Client
Public Sub New(ByVal id As Integer, ByVal description As String)
Me.id = id
Me.description = description
End Sub
Property id As Integer
Prop
我希望在数据帧中添加一个变量的级别,并为它分配同一变量中其他级别的平均值。我不知道该怎么做。因此,我想在变量trt中添加级别“基”。在这里,我想得到变量"pointA“、"pointB”和"pointC“的trt "OA”和"OB“的平均值。
id <- rep(1:3,each=5)
trt <- rep(c("A","OA", "B", "OB","base"),3)
pointA <- sample(1:10,15, replace=TRUE)
