If you're working with Java, the official [Infisical Java SDK](https://github.com/Infisical/sdk/tree/main/languages/java) package is the easiest way to fetch and work with secrets for your application.

- [Maven Package](https://github.com/Infisical/sdk/packages/2019741)
- [Github Repository](https://github.com/Infisical/sdk/tree/main/languages/java)

## Basic Usage

```java
package com.example.app;

import com.infisical.sdk.InfisicalClient;
import com.infisical.sdk.schema.*;

public class Example {
    public static void main(String[] args) {
        // Create a new Infisical Client
        ClientSettings settings = new ClientSettings();
        settings.setClientID("MACHINE_IDENTITY_CLIENT_ID");
        settings.setClientSecret("MACHINE_IDENTITY_CLIENT_SECRET");
        settings.setCacheTTL(Long.valueOf(300)); // 300 seconds, 5 minutes

        InfisicalClient client = new InfisicalClient(settings);

        // Create the options for fetching the secret
        GetSecretOptions options = new GetSecretOptions();
        options.setSecretName("TEST");
        options.setEnvironment("dev");
        options.setProjectID("PROJECT_ID");

        // Fetch the sercret with the provided options
        GetSecretResponseSecret secret = client.getSecret(options);

        // Print the value
        System.out.println(secret.getSecretValue());

        // Important to avoid memory leaks!
        // If you intend to use the client throughout your entire application, you can omit this line.
        client.close();
    }
}
```

This example demonstrates how to use the Infisical Java SDK in a Java application. The application retrieves a secret named `TEST` from the `dev` environment of the `PROJECT_ID` project.

<Warning>
    We do not recommend hardcoding your [Machine Identity Tokens](/platform/identities/overview). Setting it as an environment variable would be best.
</Warning>

# Installation

The Infisical Java SDK is hosted on the GitHub Packages Apache Maven registry. Because of this you need to configure your environment properly so it's able to pull dependencies from the GitHub registry. Please check [this guide from GitHub](https://docs.github.com/en/packages/working-with-a-github-packages-registry/working-with-the-apache-maven-registry) on how to achieve this.

Our package is [located here](https://github.com/Infisical/sdk/packages/2019741). Please follow the installation guide on the page.

# Configuration

Import the SDK and create a client instance with your [Machine Identity](/platform/identities/universal-auth).

```java
import com.infisical.sdk.InfisicalClient;
import com.infisical.sdk.schema.*;

public class App {
    public static void main(String[] args) {

        ClientSettings settings = new ClientSettings();
        settings.setClientID("MACHINE_IDENTITY_CLIENT_ID");
        settings.setClientSecret("MACHINE_IDENTITY_CLIENT_SECRET");

        InfisicalClient client = new InfisicalClient(settings); // Your client!
    }
}
```

### ClientSettings methods

<ParamField query="options" type="object">
    <Expandable title="properties">
        <ParamField query="setClientID()" type="string" optional>
            Your machine identity client ID.
        </ParamField>
          <ParamField query="setClientSecret()" type="string" optional>
            Your machine identity client secret.
        </ParamField>

         <ParamField query="setAccessToken()" type="string" optional>
            An access token obtained from the machine identity login endpoint.
        </ParamField>

        <ParamField query="setCacheTTL()" type="number" default="300" optional>
            Time-to-live (in seconds) for refreshing cached secrets.
            If manually set to 0, caching will be disabled, this is not recommended.
        </ParamField>

        <ParamField query="setSiteURL()" type="string" default="https://app.infisical.com" optional>
            Your self-hosted absolute site URL including the protocol (e.g. `https://app.infisical.com`)
        </ParamField>
    </Expandable>

</ParamField>

### Caching

To reduce the number of API requests, the SDK temporarily stores secrets it retrieves. By default, a secret remains cached for 5 minutes after it's first fetched. Each time it's fetched again, this 5-minute timer resets. You can adjust this caching duration by setting the "cacheTTL" option when creating the client.

## Working with Secrets

### client.listSecrets(options)

```java
ListSecretsOptions options = new ListSecretsOptions();
options.setEnvironment("dev");
options.setProjectID("PROJECT_ID");
options.setPath("/foo/bar");
options.setIncludeImports(false);

SecretElement[] secrets = client.listSecrets(options);
```

Retrieve all secrets within the Infisical project and environment that client is connected to
