提问by Som
I am reading a property file which consists of a message in the UTF-8 character set.
我正在读取一个属性文件，该文件由 UTF-8 字符集中的消息组成。
Problem
问题
The output is not in the appropriate format. I am using an InputStream.
输出格式不正确。我正在使用一个InputStream.
The property file looks like
属性文件看起来像
username=LBSUSER
password=Lbs@123
url=http://localhost:1010/soapfe/services/MessagingWS
timeout=20000
message=Spanish character are = {á é í, ó,ú ,ü, ?, ?, ?, á, é, í, ó, ú, ü, ?, ?, ?, °, 4° a?o = cuarto a?o, , ￠, ￡, ￥}
And I am reading the file like this,
我正在阅读这样的文件，
Properties props = new Properties();
props.load(new FileInputStream("uinsoaptest.properties"));
String username = props.getProperty("username", "test");
String password = props.getProperty("password", "12345");
String url = props.getProperty("url", "12345");
int timeout = Integer.parseInt(props.getProperty("timeout", "8000"));
String messagetext = props.getProperty("message");
System.out.println("This is soap msg : " + messagetext);
The output of the above message is
上述消息的输出是
You can see the message in the console after the line
您可以在行后在控制台中看到消息
{************************ SOAP MESSAGE TEST***********************}
{************************ SOAP MESSAGE TEST***********************}
I will be obliged if I can get any help reading this file properly. I can read this file with another approach but I am looking for less code modification.
如果我能在正确阅读此文件时获得任何帮助，我将不胜感激。我可以用另一种方法读取这个文件，但我正在寻找更少的代码修改。

Use an InputStreamReaderwith Properties.load(Reader reader):
使用InputStreamReader与Properties.load(Reader reader)：
FileInputStream input = new FileInputStream(new File("uinsoaptest.properties"));
props.load(new InputStreamReader(input, Charset.forName("UTF-8")));
回答by Binkan Salaryman
Use props.load(new FileReader("uinsoaptest.properties"))instead. By default it uses the encoding Charset.forName(System.getProperty("file.encoding"))which can be set to UTF-8 with System.setProperty("file.encoding", "UTF-8")or with the commandline parameter -Dfile.encoding=UTF-8.
使用props.load(new FileReader("uinsoaptest.properties"))来代替。默认情况下，它使用Charset.forName(System.getProperty("file.encoding"))可以通过System.setProperty("file.encoding", "UTF-8")命令行参数设置为 UTF-8的编码-Dfile.encoding=UTF-8。

You should specify the UTF-8 encoding when you construct your FileInputStream object. You can use this constructor:
您应该在构造 FileInputStream 对象时指定 UTF-8 编码。您可以使用此构造函数：
new FileInputStream("uinsoaptest.properties", "UTF-8");
If you want to make a change to your JVM so as to be able to read UTF-8 files by default, you will have to change the JAVA_TOOL_OPTIONS in your JVM options to something like this :
如果您想对 JVM 进行更改以便能够默认读取 UTF-8 文件，则必须将 JVM 选项中的 JAVA_TOOL_OPTIONS 更改为如下所示：
-Dfile.encoding=UTF-8

If somebody use @Value annotation, could try StringUils.
如果有人使用 @Value 注释，可以尝试 StringUils。
@Value("${title}")
private String pageTitle;
public String getPageTitle() {
return StringUtils.toEncodedString(pageTitle.getBytes(Charset.forName("ISO-8859-1")), Charset.forName("UTF-8"));
}
