|
|
A Java wrapper for [Ollama](https://github.com/jmorganca/ollama/blob/main/docs/api.md) APIs.
|
|
|
|
|
|
|
|
Install:
|
|
|
|
From [Maven Central](https://s01.oss.sonatype.org/#nexus-search;quick~ollama4j):
|
|
|
|
```xml
|
|
|
|
<dependency>
|
|
<groupId>io.github.amithkoujalgi</groupId>
|
|
<artifactId>ollama4j</artifactId>
|
|
<version>1.0-SNAPSHOT</version>
|
|
</dependency>
|
|
```
|
|
|
|
You might want to include the Maven repository to pull the ollama4j library from. Include this in your `pom.xml`:
|
|
|
|
```xml
|
|
|
|
<repositories>
|
|
<repository>
|
|
<id>ollama4j-from-ossrh</id>
|
|
<url>https://s01.oss.sonatype.org/content/repositories/snapshots</url>
|
|
</repository>
|
|
</repositories>
|
|
```
|
|
|
|
Verify if the ollama4j dependencies have been resolved by running:
|
|
|
|
```xml
|
|
mvn clean install
|
|
```
|
|
|
|
Start Ollama Container:
|
|
|
|
```
|
|
docker run -v ~/ollama:/root/.ollama -p 11434:11434 ollama/ollama
|
|
```
|
|
|
|
Pull a model:
|
|
|
|
```java
|
|
public class Main {
|
|
public static void main(String[] args) throws Exception {
|
|
String host = "http://localhost:11434/";
|
|
OllamaAPI ollamaAPI = new OllamaAPI(host);
|
|
ollamaAPI.pullModel(OllamaModel.LLAMA2);
|
|
}
|
|
}
|
|
```
|
|
|
|
Post a question to Ollama using Ollama4j:
|
|
|
|
Using sync API:
|
|
|
|
```java
|
|
public class Main {
|
|
public static void main(String[] args) throws Exception {
|
|
String host = "http://localhost:11434/";
|
|
OllamaAPI ollamaAPI = new OllamaAPI(host);
|
|
String response = ollamaAPI.runSync(OllamaModel.LLAMA2, "Who are you?");
|
|
System.out.println(response);
|
|
}
|
|
}
|
|
```
|
|
|
|
Using async API:
|
|
|
|
```java
|
|
public class Main {
|
|
public static void main(String[] args) throws Exception {
|
|
String host = "http://localhost:11434/";
|
|
OllamaAPI ollamaAPI = new OllamaAPI(host);
|
|
OllamaAsyncResultCallback ollamaAsyncResultCallback = ollamaAPI.runAsync(OllamaModel.LLAMA2, "Who are you?");
|
|
while (true) {
|
|
if (ollamaAsyncResultCallback.isComplete()) {
|
|
System.out.println(ollamaAsyncResultCallback.getResponse());
|
|
break;
|
|
}
|
|
Thread.sleep(1000);
|
|
}
|
|
}
|
|
}
|
|
```
|
|
|
|
You'd then get a response from Ollama:
|
|
|
|
```

I am LLaMA, an AI assistant developed by Meta AI that can understand and respond to human input in a conversational manner. I am trained on a massive dataset of text from the internet and can generate human-like responses to a wide range of topics and questions. I can be used to create chatbots, virtual assistants, and other applications that require natural language understanding and generation capabilities.
