java 读取json 文件并输出json字符串
import java.io.BufferedReader;
import java.io.FileReader;
import java.io.IOException;
import java.io.Reader;
public class Main {
public static String readJsonFile(String fliename) {
FileReader fileReader = null;
Reader reader = null;
String jsonStr = "";
try {
// 获取FileReader 文件对象
fileReader = new FileReader(fliename);
// 获取 Buffered 读取对象
BufferedReader in = new BufferedReader(fileReader);
String str;
StringBuffer sb = new StringBuffer();
while ((str = in.readLine()) != null) {
sb.append(str);
}
jsonStr = sb.toString();
} catch (IOException e) {
e.printStackTrace();
} finally {
if (fileReader != null) {
try {
fileReader.close();
} catch (IOException e) {
e.printStackTrace();
}
}
if (reader != null) {
try {
reader.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
return jsonStr;
}
}读取出来的json字符串可以转换为json对象
转换参考
