Try hitting the zip code search API with Spring Boot
What is the Zip Code Search API?
API published by Japan Post. You can get the zip code using REST.
Development environment
This time, we are running in the following environment.
- IDE:Spring Tool Suite 3.8.4Release
- Language: Java 1.8
- FW:Spring Boot 1.5.6
- Template engine: Thymeleaf 2.1.5
This time's leading role: Rest Template
- Spring Framework feature.
- Provides a method to call the REST API
- You can call it in just one line! !! (Open HttpConnection, write from there with BufferedWriter, read Response with BufferedReader, and so on.)
Implementation
Service Class
ZipCodeService.java
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.stereotype.Service;
import org.springframework.web.client.RestTemplate;
@Service
public class ZipCodeService {
@Autowired
@Qualifier("zipCodeSearchRestTemplate")
RestTemplate restTemplate;
/**Zip Code Search API Request URL*/
private static final String URL = "http://zipcloud.ibsnet.co.jp/api/search?zipcode={zipcode}";
public ZipCodeDto service(String zipcode) {
return restTemplate.getForObject(URL, ZipCodeDto.class, zipcode);
}
}
What is actually hitting the API is
restTemplate.getForObject
It is the part of.
Dto Receive the data obtained by hitting with RestTemplate as a Java object.
ZipCodeDto.java
package com.taku.springboot;
import java.util.ArrayList;
import java.util.List;
public class ZipCodeDto {
/**status*/
int status;
/**message*/
String message;
/**Postal code information list*/
List<ZipCodeDataDto> results = new ArrayList<>();
I will actually move it
thus…
like this!
