Exceptionless.Java

The definition of the word exceptionless is: to be without exception. Exceptionless provides real-time error reporting for your Java apps. It organizes the gathered information into simple actionable data that will help your app become exceptionless!

Using Exceptionless

Refer to the Exceptionless documentation here: Exceptionless Docs.

This project is available to install through Maven.

class ExampleApp {

        private static final ExceptionlessClient client =
                ExceptionlessClient.from(
                        System.getenv("EXCEPTIONLESS_SAMPLE_APP_API_KEY"),
                        System.getenv("EXCEPTIONLESS_SAMPLE_APP_SERVER_URL"));

        // Submit different events using submitXXX methods
        client.submitLog("Test log");

        // Submit custom methods using our createXXX methods
        client.submitEvent(
                EventPluginContext.from(
                        client.createLog("test-log").referenceId("test-reference-id").build()));
    }
}

Builder Pattern

We love our builders!!! This project heavily utilized the use of builders instead of traditional object creation using new. We do this with the help of Project Lombok's @Builder annotation. Read more about the project here. Read more about the annotation here. Read more about the builder pattern here.

Example: Customizing your Event Queue implementation

EventQueueIF queue = //get your implementation
Configuration configuration = Configuration.builder()
        .serverUrl("http://your-server-url")
        .apiKey("your-api-key")
        .queue(queue)
        .build();
ExceptionlessClient client = ExceptionlessClient.builder().configuration(configuration).build();

In this library we have made sure that all the values which are not set by builders fallback to reasonable defaults. So don't feel the pressure to supply values for all the fields. Note: Whenever customizing the client using Configuration never forget to supply your serverUrl and apiKey using a Configuration object as shown above.

Getting Started (Development)

Intellij

1. You will need to install:
   • Intellij
   • Note: In Intellij you can directly download JDK 11 from the IDE. Intellij also comes with a bundled Maven installation and built-in Lombok support.
2. Clone the repo
3. Verify your setup using mvn clean verify

VSCode

1. You will need to install:
   • VSCode
   • JDK 11. Make sure that your java --version and $JAVA_HOME environment variable point to the correct jdk.
   • VSCode Java extension pack
   • VSCode Lombok extension
2. Clone the repo
3. Verify your setup using mvn clean verify

Spring Boot Users

You can observe NoClassDefFoundError in your Spring-boot apps because Spring-boot uses v3 of OkHttpClient while this client uses v4. In that case you have to explicitly declare v4 of the library in you pom.xml/build.gradle.

VSCode Users

We are using Project Lombok to automatically generate a lot of code. Intellij can give you IntelliSense by default but for VSCode you may have to install this extension.

General Data Protection Regulation

By default the Exceptionless Client will report all available metadata including potential PII data. You can fine tune the collection of information via Data Exclusions or turning off collection completely.

Please visit the docs for detailed information on how to configure the client to meet your requirements.
