1.編寫json數據文件

{"data": [{"xl": [{"value": "選項1","label": "二學位畢業"},{"value": "選項2","label": "二學位畢業"},{"value": "選項3","label": "本科生畢業"},{"value": "選項4","label": "本科生結業"}]},{"zzmm": [{"value": "選項1","label": "中共黨員"},{"value": "選項2","label": "中共預備黨員"},{"value": "選項3","label": "共青團員"},{"value": "選項4","label": "群眾"},{"value": "選項6","label": "民革會員"},{"value": "選項7","label": "民盟盟員"},{"value": "選項8","label": "民鍵會員"},{"value": "選項9","label": "民進會員"},{"value": "選項10","label": "農工黨黨員"},{"value": "選項11","label": "致公堂黨員"},{"value": "選項12","label": "九三學社社員"},{"value": "選項13","label": "臺盟盟員"},{"value": "選項14","label": "無黨派民主人士"}]}] }

2.引入依賴

引入相關依賴 借助 fastjson 依賴

<!-- fastjson --> <dependency><groupId>com.alibaba</groupId><artifactId>fastjson</artifactId><version>1.2.48</version> </dependency>

3.具體實現

編寫工具類 JsonUtil.java

import java.io.File; import java.io.FileInputStream; import java.io.InputStreamReader; import java.io.Reader;public class JsonUtil {/*** 讀取JSON文件轉換為字符串* @param filePath* @return*/public static String readJsonFile(String filePath) {String jsonStr = "";try {File jsonFile = new File(filePath);Reader reader = new InputStreamReader(new FileInputStream(jsonFile), "utf-8");int ch = 0;StringBuffer sb = new StringBuffer();while ((ch = reader.read()) != -1) {sb.append((char) ch);}reader.close();jsonStr = sb.toString();return jsonStr;} catch (Exception ex) {ex.printStackTrace();return null;}} }

4.讀取轉換

對象形式讀取轉換

// 獲取json數據文件@RequestMapping("/get/json")@ResponseBodypublic Object json(){String jsonStr = JsonUtil.readJsonFile("src/main/resources/static/json/package.json");JSONObject result = JSONObject.parseObject(jsonStr);return result;}

5.數據獲取測試

采用 apipost 進行數據數據測試

vue.js采用 axios 獲取

//獲取json文件數據getJson(){axios.get("/get/json").then(res =>{json = res.data.dataconsole.log(json)})},
