Is it possible to configure a non-static value for the metadata field in the wildly json-formatter?
I didn't find anything about it in the wildfly documentation- it only has a simple static field example (meta-data=[#version=1])
For example, I would like to have a field "simpleClassName" - The class of the code calling the log method.
I also tried to use a similar syntax to pattern-formatter(example below) but it doesn't work
<formatter name="JSON">
<json-formatter>
<meta-data>
<property name="simpleClassName" value="%c{1}"/>
</meta-data>
</json-formatter>
</formatter>
No the meta-data is only static information. However what you're looking for seems to be the details of the caller. Note that this is an expensive operation should you should use it with caution. What you'd want to do is change the print-details to true. In CLI it would be something like:
/subsystem=logging/json-formatter=JSON:write-attribute(name=print-details, value=true)

We want to make compliance easy and for FedRAMP want something like this on all fields in our database objects
#FedRamp(confidentiality=LOW, integrity=MODERATE, availability=HIGH)
We want checkstyle to break the builds if people add data and forget to add these on 'any' field in the *Dbo.java class. Then, we can generate the FedRAMP compliance on each data item (and therefore the entire system). We run checkstyle on every class but only want this rule run on classes ending in *Dbo.java. Is this possible where we import some already existing checkstyle rule or plugin and add the class name filter to it?
thanks,
Dean
To report violations for such cases for any classes, you can use MatchXpathCheck (you need checkstyle 8.39+)
Config will look like:
<?xml version="1.0"?>
<!DOCTYPE module PUBLIC
"-//Checkstyle//DTD Checkstyle Configuration 1.3//EN"
"https://checkstyle.org/dtds/configuration_1_3.dtd">
<module name = "Checker">
<module name="TreeWalker">
<module name="MatchXpath">
<property name="id" value="fedramp_check"/>
<property name="query" value="//CLASS_DEF/OBJBLOCK/VARIABLE_DEF/MODIFIERS/ANNOTATION/IDENT[not(#text='FedRamp')]"/>
<message key="matchxpath.match"
value="Field should have 'FedRamp' annotation."/>
</module>
</module>
</module>
This will report violations like this:
$ cat Test.java
class Test {
#FedRamp(confidentiality=LOW, integrity=MODERATE, availability=HIGH)
private int withAnnotation = 11; // no violation
#Fed(confidentiality=LOW, integrity=MODERATE, availability=HIGH)
private int without = 11; // violation
#NotNull
int without = 11; // violation
}
$ java -jar checkstyle-8.42-all.jar -c config.xml Test.java
Starting audit...
[ERROR] C:\workdir\Test.java:6:4: Field should have FedRamp annotation. [fedramp_check]
[ERROR] C:\workdir\Test.java:9:4: Field should have FedRamp annotation. [fedramp_check]
Audit done.
Checkstyle ends with 2 errors.
Second part of your question - narrow execution only to specific classes - can be solved in several ways.
Use a bit different xpath to filter class names (not files, since there can be many classes in single file)
<property name="query"
value="//CLASS_DEF[./IDENT[ends-with(#text,
'Dbo')]]/OBJBLOCK/VARIABLE_DEF/MODIFIERS/ANNOTATION/IDENT[not(#text='FedRamp')]"/>
Use BeforeExecutionExclusionFileFilter - it is filter for whole config and will work ok only if you have a separate config only for checking annotation thing.
Suppress violations for this check (by id, for example) for other class files, see doc
Chisel throws an exception with an elaboration error message. The following is a result of my code as an example.
chisel3.core.Binding$ExpectedHardwareException: data to be connected 'chisel3.core.Bool#81' must be hardware, not a bare Chisel type. Perhaps you forgot to wrap it in Wire(_) or IO(_)?
This exception message is interesting because 81 behind chisel3.core.Bool# looks like ID, not hashcode.
Indeed, Data type extends HasId trait which has _id field, and
_id field seems to generate a unique ID for each components.
I've thought Data type overrides toString to make string that has type#ID, but it does not override. That is why $node in below code should not be able to use ID.
throw Binding.ExpectedHardwareException(s"$prefix'$node' must be hardware, " +
"not a bare Chisel type. Perhaps you forgot to wrap it in Wire(_) or IO(_)?")
Instead of toString, toNamed method exists in Data. However, this method seems to be called to generate a firrtl code, not to convert component into string.
Why can Data type show its ID?
If it is not ID, but exactly hashcode, this question is from my misunderstanding.
I think you should take a look at Chisel PR #985. It changes the way that Data's toString method is implemented. I'm not sure if it answers your question directly but it's possible this will make the meaning and location of the error clearer. If not you should comment on it.
Scala classes come with a default toString method that is of the form className#hashCode.
As you noted, the chisel3.core.Bool#81 sure looks like it's using the _id rather than the hashCode. That's because in the most recently published version of Chisel (3.1.6), the hashcode was the id! You can see this if you inspect the source files at the tag for that version: https://github.com/freechipsproject/chisel3/blob/dc4200f8b622e637ec170dc0728c7887a7dbc566/chiselFrontend/src/main/scala/chisel3/internal/Builder.scala#L81
This is no longer the case on master which probably the source of any confusion! As Chick noted, we have just changed the .toString method to be more informative than the default; expect more informative representations in 3.2.0!
I have a DecoraManager implementation : AppDecoraManager, and want to inject a service e.g.: FooService as:
#PetiteInject
FooService fooService;
When resolveDecorator() is called I want to use fooService to determine some parameters, but it has null value.
What could be the reason for this, and how could I resolve it?
DecoraManager is created by the servlet container, in DecoraServletFilter.
At the moment, there is no integration with existing Petite IOC, so you have to do the following:
First, you need to have a public static reference to PetiteContainer. Store it during the creation of container, for example.
Override createDecoraManager() in your implementation
Use PetiteContainer.wire(this) in your implementation of DecoraManager.
That is the only way to do so, so far.
The alternative would be this:
Register DecoraManager as #PetiteBean.
Again, get the static reference to PetiteContainer
In createDecoraManager use PetiteContainer.get() to get the instance.
In the first example, DecoraManager gets just wired; in the second example, it gets stored in Petite container, too.
I am using logback with a third party package which sets an identifier in the MDC when its code is running. The rest of the time, this identifier is not set. So if I use a PatternLayout of [%X{id}] %m%n, then I see messages like
[Foo] Foo running
[Bar] Bar running
for messages related to the package. However, the rest of my log statements look like
[] Thing happened
The %X{id} is useful information when it exists, but I would like the logger name to be used when it is not. I tried
[%X{id:-%logger{20}}]
and
[%X{id:-logger{20}}]
but neither used the logger name as a default value.
I could write a custom layout that sets id to the logger name if it is not set, forwards to the layout and then clears field. Is there a simpler way to do this?
I am using SpringBatch to write a csv-file to the database. This works just fine.
I am using a FlatFileItemReader and a custom ItemWriter. I am using no processor.
The import takes quite some time and on the UI you don't see any progress. I implemented a progress bar and got some global properties where i can store some information (like lines to read or current import index).
My question is: How can i get the number of lines from the csv?
Here's my xml:
<batch:job id="importPersonsJob" job-repository="jobRepository">
<batch:step id="importPersonStep">
<batch:tasklet transaction-manager="transactionManager">
<batch:chunk reader="personItemReader"
writer="personItemWriter"
commit-interval="5"
skip-limit="10">
<batch:skippable-exception-classes>
<batch:include class="java.lang.Throwable"/>
</batch:skippable-exception-classes>
</batch:chunk>
<batch:listeners>
<batch:listener ref="skipListener"/>
<batch:listener ref="chunkListener"/>
</batch:listeners>
</batch:tasklet>
</batch:step>
<batch:listeners>
<batch:listener ref="authenticationJobListener"/>
<batch:listener ref="afterJobListener"/>
</batch:listeners>
</batch:job>
I already tried to use the ItemReadListener Interface, but this isn't possible as well.
if you need to know how many lines where read, it's available in spring batch itself,
take a look at the StepExecution
The method getReadCount() should give you the number you are looking for.
You need to add a step execution listener to your step in your xml configuration. To do that (copy/pasted from spring documentation):
<step id="step1">
<tasklet>
<chunk reader="reader" writer="writer" commit-interval="10"/>
<listeners>
<listener ref="chunkListener"/>
</listeners>
</tasklet>
</step>
where "chunkListner" is a bean of yours annotated with a method annotated with #AfterStep to tell spring batch to call it after your step.
you should take a look at the spring reference for step configuration
Hope that helps,
