前言
该功能模块基于springBoot，自己在开发中遇到相关功能开发，总结如写：
1.首先将所需要获取的json文件放在项目resource目录下：
2.所需要的pom依赖：
<dependency>
<groupId>com.alibaba</groupId>
<artifactId>fastjson</artifactId>
<version>1.2.47</version>
</dependency>
3.读取JSON工具类
/**
* 读取json文件，返回json串
* @param fileName
* @return
*/
public static String readJsonFile(String fileName) {
String jsonStr = "";
try {
File jsonFile = new File(fileName);
FileReader fileReader = new FileReader(jsonFile);
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);
}
fileReader.close();
reader.close();
jsonStr = sb.toString();
return jsonStr;
} catch (IOException e) {
e.printStackTrace();
return null;
}
}
4.测试类
public class TestJson {
public static void main(String[] args) throws Exception{
// 假设我下面json文档有10个 名字:1 -10.json
for (int j = 1; j < 10; j++) {
String srcpath = j+".json";
String path = ElectronicWaybillController.class.getClassLoader().getResource(srcpath).getPath();
String s = readJsonFile(path);
JSONObject jobj = JSON.parseObject(s);
//构建JSONArray数组
JSONArray movies = jobj.getJSONArray("content");
for (int i = 0 ; i < movies.size();i++){
JSONObject key = (JSONObject)movies.get(i);
ElectronicWaybillDetailsDTO electronicWaybillDetailsDTO = new ElectronicWaybillDetailsDTO();
electronicWaybillDetailsDTO.setDriverName((String)key.get("driverName"));
electronicWaybillDetailsDTO.setAreaCode((String)key.get("organCode"));
electronicWaybillDetailsDTO.setCanBodyNo((String)key.get("tankNum"));
这里字段较多，以上写以上几个作为代表
electronicWaybillService.insert(electronicWaybillDetailsDTO);
}
}
