定义一个长度为10的数组,并给默认值。 然后由控制台输入两个整数,第一个表示要访问的数组的索引 第二个表示获得的元素要除以的数字 结果为将第一个数字对应索引的数组元素值除以输入的第二个数字. 实现从控制台输入三个数值作为三角形的三条边,以此构造一个三角形。程序应该实现如下功能: -->检查输入的命令行参数是否为数值格式,如果输入的数值参数格式错误,则程序可能产生 InputMismatchException异常(java.util.InputMismatchException 需要导入这个类) -->检查输入的命令行参数中是否有负值或0,如果有负值或0,则程序可能产生 NumberValueException异常( NumberValueException为自定义异常) -->检查输入的命令行参数的三个数值是否能够构造一个三角形,如果不能构造一个三角形, 则程序可能产生TriangleException异常(TriangleException为自定义异常) -->没出现异常则显示三个数字. 1.编写宠物店类 提供方法:出售宠物 Pet sellPet(int i) 传入1 则返回猫对象,2 则返回狗对象 2.若传入的参数不是1或2,则抛出异常,显示:类型错误!!! 3.在方法内使用try catch 处理异常,注意:思考出现异常时如何处理返回值 4.无论是否有异常 都要能输出一句话:“欢迎下次光临” 5.测试sellPet() 方法,调用返回的对象的cry方法. a、 声明一个抽象方法taste(),该方法负责输出饮料的味道; b、 声明int型常量来代表不同的饮料类型(咖啡、啤酒、牛奶),如: c、 声明静态方法getDrink(int drinkType),根据传入的参数创建不同的饮料对象,并返回该对象,建议使用switch语句。该方法要求声明DrinkNotFoundException,当没有相对应的饮料类型时,抛出该异常。 2、 建立Drink的具体子类: a、 分别建立Drink的子类:Coffee(代表咖啡),Beer(代表啤酒),Milk(代表牛奶); b、 实现taste()方法,要求在控制台打印各自的味道特征。 建立异常类. 3、 a、 继承Exception b、 在Drink的方法getDrink(int drinkType)中声明引发DrinkNotFoundException异常,当传入的参数没有相对应的饮料类型时,抛出异常。 c、 在使用getDrink方法的类中捕捉该异常。 4、 建立Test测试类,测试以上内容的正确性 a、 编写main方法,通过命令行传参的方式传入某种饮料的类型。 b、 在main方法中,调用Drink类的getDrink方法,获得相应的饮料对象。注意捕获DrinkNotFoundException。 c、 然后调用该饮料对象的taste()方法,输出该饮料的味道。 5、 编译程序,并运行。.

QUESTION
While writing code using Spring/Java and Aspect oriented programing, I'm facing an issue. In the service class, I have the retry method using @Retryable and a recovery method using @Recover.
Each of these 2 methods are attached to Aspects. The Retryable method - "triggerJob" inside TestProcessService is attached to these methods in TestAspect class - beforeTestTriggerJobsAdvice, afterTestTriggerJobsAdvice, onErrorTestTriggerJobsAdvice. They all are working fine and getting triggered at the right time.
PROBLEM STATEMENT: The Recovery method - "recover" inside TestProcessService is attached to these methods in TestAspect class - beforeRecoveryTestJobsAdvice, onErrorRecoveryTestTriggerJobsAdvice, and afterRecoveryTestTriggerJobsAdvice.
BUT NONE OF THESE ASPECT METHODS ARE GETTING CALLED once the code reached the recover method inside TestProcessService.
Here is the code:
SCHEDULER CLASS (triggers the methods inside TEST_MyProcessService class at regular interval)

Answered 2021-Jun-08 at 03:45I am not a Spring user, but interested in all things AOP, both AspectJ and Spring AOP. I liked your little puzzle. Thanks to your MCVE, I was able to reproduce the issue and debug into it. This is a perfect example for why an MCVE is so much superior to simply posting a bunch of code snippets. So thanks for that, please keep up this way of asking questions.
When looking at the situation in a debugger, you see that while the aspect is proceeding into triggerJob
, at some point we are in method AnnotationAwareRetryOperationsInterceptor.invoke
and there we have the following code:

QUESTION
I am using Microsoft.CodeDom.Providers.DotNetCompilerPlatform
nuget packge for compilation of code at runtime. It is achievable but in my scenario my dynamic class needs to use Postsharp
for aspect oriented programming.
Can anyone point me to the commandline support to add Postsharp
dependency injection for the compiled assembly using the csc.exe
, like what is done by the MSBuild or Visualstudio.
ANSWER
Answered 2020-Aug-17 at 10:26You can't easily do that with the current versions of PostSharp. The last version to have command-line execution is 5.0 and that is no longer supported.
The problem is that PostSharp reads too many properties in MSBuild or passed to it by MSBuild.
If it's possible for you to generate an msbuild file, you can then build it the Microsoft.Build NuGet package and have PostSharp run on the generated code that way.

QUESTION
I'm trying to get started with aspect oriented programming. I'm using latest eclipse (currently 12-2019)
...ANSWER
Answered 2020-Jan-05 at 14:42Your problem caused by the removal of org.eclipse.core.runtime.compatibility
plugin from Eclipse 4.6 .
Read more about this problem here.
The correct solution is to:
Install AspectJ
from the correct download link.
The most updated to Eclipse 4.10 is: http://download.eclipse.org/tools/ajdt/410/dev/update
Another solution is to:
Uninstall Eclipse.
Install Eclipse 4.3 (matching your
AspectJ
version) .Retry AspectJ install.
The more complex solution is:
Locate and build/extract
org.eclipse.core.runtime.compatibility
jar file from Maven repository.Put
org.eclipse.core.runtime.compatibility
jar file into Eclipse plugins directory.Run
eclipse
in--clean
mode to rebuild and register the added plugin.Retry AspectJ install.
You might encounter more missing dependencies for org.eclipse.core.runtime.compatibility
, eventually will have to load all the related plugins (long effort).
