Java client to report exceptions to the ⚡ Honeybadger.io error notification service. Receive instant notification of exceptions and errors in your Java applications.
This is a library for sending errors that implement java.lang.Throwable on the JVM to the online error reporting service Honeybadger.
You can find the library on Maven Central or you can always clone this github repository.
If you want to send all unhandled errors to Honeybadger and have them logged to slf4j via the error log level, you will need to set some system properties and add a single line to the thread in which you want to register the error handler.
A typical stand-alone implementation may look like:
import io.honeybadger.reporter.HoneybadgerUncaughtExceptionHandler;
public static void main(String argv[]) {
HoneybadgerUncaughtExceptionHandler.registerAsUncaughtExceptionHandler();
// The rest of the application goes here
}A servlet based implementation may look like:
In your web.xml file:
<!-- Send all uncaught servlet exceptions and servlet request details to Honeybadger -->
<filter>
<filter-name>HoneybadgerFilter</filter-name>
<filter-class>io.honeybadger.reporter.servlet.HoneybadgerFilter</filter-class>
<init-param>
<param-name>honeybadger.api_key</param-name>
<param-value>API KEY GOES HERE</param-value>
</init-param>
<init-param>
<param-name>honeybadger.excluded_sys_props</param-name>
<param-value>bonecp.password,bonecp.username</param-value>
</init-param>
<init-param>
<param-name>honeybadger.excluded_exception_classes</param-name>
<param-value>org.apache.catalina.connector.ClientAbortException</param-value>
</init-param>
<!-- By default this is true. Toggle to false if you don't want users to be able
to send feedback. -->
<init-param>
<param-name>honeybadger.display_feedback_form</param-name>
<param-value>false</param-value>
</init-param>

</filter-mapping>This library has been tested against Play 2.4.2. You can add Honeybadger as an error handler by adding the library to your SBT build file:
libraryDependencies += "io.honeybadger" % "honeybadger-java" % "<<VERSION NUMBER>>"
And then by adding the following line to your conf/application.conf file:
play.http.errorHandler=io.honeybadger.reporter.play.HoneybadgerErrorHandler
This will allow the library to wrap the default error handler implementation and pass around Honeybadger error ids instead of the default Play error ids.
If you want to send exceptions to HoneyBadger without having to register an uncaught
exception handler, you can create an instance of HonebadgerReporter and call
the reportError(Throwable error) method directly.
All dependencies needed for running are included in the distributed JAR with one exception - slf4j-api. We expect that you are using some logging library and that you have imported the sl4j-api in order to provide a common interface for the logger to imported libraries. If you are using Maven, Gralde or Ivy, this should happen automatically for you. If you are using Ant, you will need to import the slf4j-api jar and an sl4j implementation.
For the purpose of one off testing, you can use the CLI utility. Just execute it using
./gradlew run and you can enter in your API key and message to be sent to
Honeybadger.
This library by requires access to the remote Honeybadger API, so in order to run automated tests you will need to specify system properties to Java in order configure the remote API key and other settings.
If you are running the tests from gradle, it is easy to specify system properties using a gradle.properties file placed in the root of the project or in your $HOME/.gradle directory.
A sample gradle.properties file may look like:
systemProp.ENV = TEST
systemProp.honeybadger.api_key = 1efa3d71
With this in place you can run the tests from gradle by using the wrapped version of gradle that is bundled with the project by:
./gradlew test
If you are executing your tests from an IDE like IntelliJ, you may need to manually set the system variables as part of the test run configuration.
For developers pushing to Maven repositories, you will need to specify the location of your signing keys in gradle.properties. You also shouldn't put the file in the project root, but rather store it in your .gradle directory within your home directory. Properties for signing look like:
signing.keyId=345A20CE
signing.password=J6N0phB*f3aRH4bZ
signing.secretKeyRingFile=/home/user/.gnupg/secring.gpg
ossrhUsername=user
ossrhPassword=AFbz3BjdE4Q9g2E&
The following properties are available:
ENV
-------------
Sample Value: production
Required?: No
Default Value: development
Description: Any string value. String sent to Honeybadger indicating running
environment (eg development, test, staging, production, etc). This
property can also be read from an environment variable.
JAVA_ENV
-------------
Sample Value: production
Required?: No
Default Value: development
Description: Any string value. String sent to Honeybadger indicating running
environment (eg development, test, staging, production, etc). This
property can also be read from an environment variable. This is the
same as ENV, it is only here to provide compability with systems
that use it to indicate running environment.
honeybadger.api_key
-------------
Sample Value: 29facd41
Required?: Yes
Default Value: N/A
Description: The API key found in the settings tab in the Honeybadger UI.
honeybadger.url
-------------
Sample Value: https://alternative.host
Required?: No
Default Value: https://api.honeybadger.io
Description: URL to the Honeybadger API endpoint. You may want to access it
without SSL in order to test with a proxy utility.
honeybadger.application_package
-------------
Sample Value: com.tech.digital.donkey
Required?: No
Default Value: N/A
Description: Java application package name used to indicate to Honeybadger what
stacktraces are within the calling application's code bade.
http.proxyHost

Sample Value: localhost
Required?: No
Default Value: N/A
Description: Standard Java system property for specifying the host to proxy all
HTTP traffic through.
http.proxyPort

Required?: No
Default Value: N/A
Description: Standard Java system property for specifying the port to proxy all
HTTP traffic through.
honeybadger.excluded_exception_classes
-------------
Sample Value: org.apache.catalina.connector.ClientAbortException,com.myorg.AnnoyingException
