您需要导入以下包

compile "org.apache.avro:avro:1.8.2"
compile "org.apache.avro:avro-tools:1.8.2"
compile "org.apache.avro:trevni-core:1.8.2"
compile "org.apache.avro:trevni-avro:1.8.2"

您可以使用trevni依赖关系和测试范围创建随机数据。这里有一个示例代码

import org.apache.avro.Schema;
import org.apache.trevni.avro.RandomData;

import java.util.Iterator;

public class JSONExample {
    public static void main(String [] args){
        Schema schema = new Schema.Parser().parse("{\n" +
                "     \"type\": \"record\",\n" +
                "     \"namespace\": \"com.acme\",\n" +
                "     \"name\": \"Test\",\n" +
                "     \"fields\": [\n" +
                "       { \"name\": \"name\", \"type\": \"string\" },\n" +
                "       { \"name\": \"age\", \"type\": \"int\" },\n" +
                "       { \"name\": \"sex\", \"type\": \"string\" },\n" +
                "       { \"name\": \"active\", \"type\": \"boolean\" }\n" +
                "     ]\n" +
                "}");

        Iterator<Object> it = new RandomData(schema, 1).iterator();
        System.out.println(it.next());
    }
}

输出

{"name": "cjnyvbmetf", "age": -1757126879, "sex": "", "active": false}
