需求是这样的：
遇到的问题是这样的：
我是这样解决的：
JSON文件转字符串:
public static String readJson(File file) {
String string = null;
if (!file.exists() || file.isDirectory()) {
System.out.println("输入路径不对");
} else {
FileInputStream fileInputStream = null;
InputStreamReader inputStreamReader = null;
BufferedReader bufferedReader = null;
try {
fileInputStream = new FileInputStream(file);
inputStreamReader = new InputStreamReader(fileInputStream, "UTF-8");
bufferedReader = new BufferedReader(inputStreamReader);
String str = null;
StringBuilder stringBuilder = new StringBuilder();
while ((str = bufferedReader.readLine()) != null) {
stringBuilder.append(str);
}
string = stringBuilder.toString();
} catch (IOException e) {
e.printStackTrace();
}
}
logger.info(string);
return string;
}
前端Vue处理: :value放字符串
<json-viewer :value="showtext" :expand-depth=4 copyable sort></json-viewer>
