Sample

import java.io.IOException;
import javax.annotation.PostConstruct;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@EnableIP2region
@SpringBootApplication
public class Application {
@Autowired
IP2regionTemplate template;
@PostConstruct
public void test() throws IOException {
     System.out.println(template.binarySearch("127.0.0.1"));
     System.out.println(template.binarySearch("127.0.0.1"));
 }
public static void main(String[] args) throws Exception {
     SpringApplication.run(Application.class, args);
 }
}

如果使用外部IP数据，可自定义配置，参考如下：

ip2region:
  external: false
  index-block-size: 4096
  total-header-size: 8192
  location: classpath:ip2region/ip2region.db
