Simple RESP (REdis Serialization Protocol) implementation for Java

RESP for Java

A simple client to write commands using the RESP (REdis Serialization Protocol) protocol.

In Redis setting a key name with value Luigi has the following syntax:

> SET name Luigi

And in RESP gets pushed on the wire as follows:

*3\r\n$3\r\nSET\r\n$4\r\nname\r\n$5\r\nLuigi  

Which means:

• The input has 3 parts
• A string ($) of 3 characters SET
• A string ($) of 4 characters name
• And a string ($) of 5 characters Luigi

Simplicity.

In Java, all you have to do is add the following maven dependency:

<dependency>
    <groupId>com.foogaro.util</groupId>
    <artifactId>resp4j</artifactId>
    <version>0.3.16</version>
</dependency>

And your code will look like the following:

String[] commands = new String[]{"SET", "name", "Luigi"};

try {
    Redis.run(redis -> redis.call(commands), "localhost", 6379);
} catch (IOException | RedisError e) {
    e.printStackTrace();
    throw new RedisException(e);
}

And your commands will be transformed into RESP commands and pushed to the Redis server.

Done.
