1、配置文件存放

resource/properties/demo.json

{"desc": "spring boot property config of json file","babbys": [{"name": "Tom","age": 2,"address": "苏州"},{"name": "Lily","age": 5,"address": "杭州"}]
}

2、实体对象

import lombok.Data;@Data
public class Demo {private String desc;private List babbys;
}

import lombok.Data;@Data
public class Babby {private String name;private Integer age;private String address;
}

3、配置

import com.fasterxml.jackson.databind.ObjectMapper;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;import org.springframework.core.io.ClassPathResource;
import org.springframework.core.io.Resource;import java.io.IOException;
import java.io.InputStream;@Configuration
public class JsonFileConfig {@Beanpublic Demo demo() throws IOException {Resource resource = new ClassPathResource("properties/demo.json");InputStream inputStream = resource.getInputStream();return new ObjectMapper().readValue(inputStream, Demo.class);}
}

4、使用

@Autowired
private Demo demo;

5、封装http请求

import org.apache.http.HttpResponse;
import org.apache.http.NameValuePair;
import org.apache.http.client.HttpClient;
import org.apache.http.client.config.RequestConfig;
import org.apache.http.client.entity.UrlEncodedFormEntity;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.StringEntity;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClientBuilder;
import org.apache.http.impl.client.HttpClients;
import org.apache.http.message.BasicNameValuePair;
import org.apache.http.util.EntityUtils;
import org.apache.logging.log4j.LogManager;
import org.apache.logging.log4j.Logger;import java.io.*;
import java.net.URI;
import java.net.URISyntaxException;
import java.util.ArrayList;
import java.util.Map;
import java.util.Set;public class HttpClientUtils {private static final Logger logger = LogManager.getLogger(HttpClientUtils.class);/*** 封装POST请求（Map入参）** @param url 请求的路径* @param map 请求的参数* @return* @throws IOException*/public static String post(String url, Map map) throws IOException {
//        1、创建HttpClient对象CloseableHttpClient httpClient = HttpClients.createDefault();
//        2、创建请求方式的实例HttpPost httpPost = new HttpPost();try {httpPost.setURI(new URI(url));} catch (URISyntaxException e) {e.printStackTrace();}
//        3、添加请求参数(设置请求和传输超时时间)RequestConfig requestConfig = RequestConfig.custom().setSocketTimeout(60000).setConnectTimeout(60000).build();httpPost.setConfig(requestConfig);ArrayList list = new ArrayList<>();Set entrySet = map.entrySet();for (Map.Entry entry : entrySet) {String key = entry.getKey().toString();String value = entry.getValue().toString();list.add(new BasicNameValuePair(key, value));}httpPost.setEntity(new UrlEncodedFormEntity(list, org.apache.http.protocol.HTTP.UTF_8));
//        4、发送Http请求HttpResponse response = httpClient.execute(httpPost);
//        5、获取返回的内容String result = null;int statusCode = response.getStatusLine().getStatusCode();if (200 == statusCode) {result = EntityUtils.toString(response.getEntity());} else {logger.info("请求第三方接口出现错误，状态码为:{}", statusCode);return null;}
//        6、释放资源httpPost.abort();httpClient.getConnectionManager().shutdown();return result;}/*** 封装POST请求（String入参）** @param url  请求的路径* @param data String类型数据* @return* @throws IOException*/public static String post(String url, String data) throws IOException {
//        1、创建HttpClient对象HttpClient httpClient = HttpClientBuilder.create().build();
//        2、创建请求方式的实例HttpPost httpPost = new HttpPost(url);
//        3、添加请求参数(设置请求和传输超时时间)RequestConfig requestConfig = RequestConfig.custom().setSocketTimeout(60000).setConnectTimeout(60000).build();httpPost.setConfig(requestConfig);httpPost.setHeader("Accept", "application/json");httpPost.setHeader("Content-Type", "application/json");
//        设置请求参数httpPost.setEntity(new StringEntity(data, "UTF-8"));
//        4、发送Http请求HttpResponse response = httpClient.execute(httpPost);
//        5、获取返回的内容String result = null;int statusCode = response.getStatusLine().getStatusCode();if (200 == statusCode) {result = EntityUtils.toString(response.getEntity());} else {logger.info("请求第三方接口出现错误，状态码为:{}", statusCode);return null;}
//        6、释放资源httpPost.abort();httpClient.getConnectionManager().shutdown();return result;}/*** 封装GET请求** @param url* @return* @throws IOException*/public static String get(String url) throws IOException {
//        1、创建HttpClient对象HttpClient httpClient = HttpClientBuilder.create().build();
//        2、创建请求方式的实例HttpGet httpGet = new HttpGet(url);
//        3、添加请求参数(设置请求和传输超时时间)RequestConfig requestConfig = RequestConfig.custom().setSocketTimeout(60000).setConnectTimeout(60000).build();httpGet.setConfig(requestConfig);
//        4、发送Http请求HttpResponse response = httpClient.execute(httpGet);
//        5、获取返回的内容String result = null;int statusCode = response.getStatusLine().getStatusCode();if (200 == statusCode) {result = EntityUtils.toString(response.getEntity());} else {logger.info("请求第三方接口出现错误，状态码为:{}", statusCode);return null;}
//        6、释放资源httpGet.abort();httpClient.getConnectionManager().shutdown();return result;}
}
