kandi X-RAY | jackson-databind Summary
This project contains the general-purpose data-binding functionality and tree-model for Jackson Data Processor. It builds on Streaming API (stream parser/generator) package, and uses Jackson Annotations for configuration. Project is licensed under Apache License 2.0. While the original use case for Jackson was JSON data-binding, it can now be used to read content encoded in other data formats as well, as long as parser and generator implementations exist. Naming of classes uses word 'JSON' in many places even though there is no actual hard dependency to JSON format.

QUESTION
I have a doubt with the dependency management in maven central. I have to say that this is a project in initial phase and I am not using my own repository, that's why I have this doubt.
GitHub dependabot tells me that the version I use jackson-databind is vulnerable.
Package com.fasterxml.jackson.core:jackson-databind (Maven) Affected versions >= 2.13.0, <= 2.13.2.0 Patched version 2.13.2.1

Answered 2022-Apr-15 at 22:21A brief search of maven central reveals that the newest version of jackson-databind is 2.13.2.2.

...ANSWER
Answered 2021-Oct-24 at 14:23The message typically entails that your JAVA_HOME environment variable points to a different Java version.
Here are the steps to follow:
- Close IntelliJ IDEA
- Open a terminal window and check your JAVA_HOME variable value:
- *nix system:
echo $JAVA_HOME
- Windows system:
echo %JAVA_HOME%
- *nix system:
- The JAVA_HOME path should be pointing to a different path, then set it to the openjdk-17 path:
- *nix system:
export JAVA_HOME=/path/to/openjdk-17
- Windows system:
set JAVA_HOME=path\to\openjdk-17
- *nix system:
- Open your project again in IntelliJ IDEA
- Make sure to set both source and target compatibility versions (not only the
sourceCompatibility
)
You should be able to build your project.
EDIT: Gradle ToolchainYou may need also to instruct Gradle to use a different JVM than the one it uses itself by setting the Java plugin toolchain to your target version:

QUESTION
We have a JavaFX based application which is not modularized (there are reasons, a legacy library is involved) but we build an custom runtime using jdeps
and jlink
.
We've recently rewritten the app and added a couple of new dependencies, as well as removing others. Now the script that is building the application suddenly stopped working during the jdeps
call.
Note: This is happening on Linux – I've yet to test other OS'ses, but I don't expect another result.
When the script calls
...ANSWER
Answered 2021-Dec-13 at 13:36Update: These issues have been fixed, and a patched version of jdeps
is available as part of the early access build for JDK 18 at: http://jdk.java.net/18/ (starting from build 26)
Turning my comments into an answer. There seem to be 3 bugs going on here:
- The
MultiReleaseException
seems to be becausejdeps
can not handle classes in different jars that have the same name, such asmodule-info.class
, but are stored in a differentMETA-INF/versions/xxx
directory. (JDK-8277165) - The fact that this exception is sometimes suddenly not occuring seems to be the result of a race condition in the code that checks for the above; classes of the same name having multiple versions. (JDK-8277166)
- The
MultiReleaseException
is missing it's exception message since it's thrown as part of an asynchronous task, which wraps it in anExecutionException
, which then leads tojdeps
not reporting the exception correctly. (JDK-8277123)
As for a workaround, I don't think there's a good one at this point, except maybe for editing all the jars on the class path so that they put the module-info.class
in the same META-INF/versions/xxx
directory (but, this might have other consequences as well, so you probably don't want to run with the edited jars, and only use them for jdeps
).
QUESTION
@Service
@AllArgsConstructor
@RequiredArgsConstructor
//@NoArgsConstructor
public class CurrencyExchange_Logic implements LogicInterface {
private final Currency_Interface currency_interface;
private final Rates_Interface rates_interface;
private final OldRates_Interface Oldrates_interface;
String start, end;
// methods
}
...ANSWER
Answered 2021-Nov-29 at 01:01Your CurrencyExchange_Logic
class has two constructors: the required args constructor, which has parameters corresponding to the 3 final
fields, and the all args constructor, with parameters corresponding to those 3 fields as well as start
and end
.
When you only have one constructor defined, Spring knows how to implicitly choose it for injection. However, when you have more than one, you have to tell it which one you want it to use, using the @Autowired
or @Inject
annotation.
I would guess you want Spring to use the required args constructor, as I doubt Spring has any way of knowing how to resolve the start
or end
fields. This can be done in lombok (@RequiredArgsConstructor(onConstructor_ = @Autowired)
), or by just explicitly writing the constructor yourself and annotating it. Note you could also get rid of the all args constructor, if you don't need it, and Spring's implicit constructor injection should "just work."

Vulnerabilities
Install jackson-databind
You can use jackson-databind like any standard Java library. Please include the the jar files in your classpath. You can also use any IDE and you can run and debug the jackson-databind component as you would do with any other Java program. Best practice is to use a build tool that supports dependency management such as Maven or Gradle. For Maven installation, please refer maven.apache.org. For Gradle installation, please refer gradle.org .
