我有这个java方法：
public class ReadIssues {
// Reads from a Json object
protected JsonArray readJson() throws IOException {
JsonArray issueArray = null;
ClassLoader cl = Thread.currentThread().getContextClassLoader();
// Get input stream for reading the specified resource
InputStream inputStream = cl.getResourceAsStream("GitHubIssue.json");
// Create JsonReader to read JSON data from a stream
Reader reader = new InputStreamReader(inputStream, "UTF-8");
JsonReader jsonReader = Json.createReader(reader);
try{
// Create an object model in memory
issueArray = jsonReader.readArray();
System.out.println("ReadIssues issueArray: " + issueArray);
}
finally {
if (inputStream != null) {
inputStream.close();
}
if (jsonReader != null) {
jsonReader.close();
}
}
return issueArray;
}
它抛出这个异常：
Exception in thread "main" javax.json.stream.JsonParsingException: Unexpected char 117 at (line no=1, column no=5, offset=4)

问题似乎是issueArray = jsonReader.readArray();。我认为body我的 JSON 中的值包含 和 等\n字符\r。
我遇到了一篇帖子，它建议做类似的事情，json = json.replaceAll("\r?\n", "");但那json是String. 在我使用 JsonReader 对象的情况下，我应该怎么做？
