ok , all info in this .
tomcat version : 8.5.55
java version : 1.8.0_181-b13
os version : Mac OS X 10.15.4
and i debug this problem this morning .
I found the final cause of this problem is because of the
**PropertyResourceBundle** class .
My test code is as follows :
`
public class Test {
public static void main(String[] args) throws IOException {
//1. inputstream
InputStream inputStream =
Test.class.getResourceAsStream("/test.properties");
PropertyResourceBundle prb1 = new
PropertyResourceBundle(inputStream);
String title1 = prb1.getString("title");
System.out.println(title1);
//2. reader
InputStreamReader reader = new
InputStreamReader(Test.class.getResourceAsStream("/test.properties"),"UTF-8");
PropertyResourceBundle prb2 = new PropertyResourceBundle(reader);
String title2 = prb2.getString("title");
System.out.println(title2);
}
}
`
the test.properties contens is :
`title=测试`
When you initialize him, the input is an InputStream , then Properties will
load this stream，The garbled problem arises here .
` public PropertyResourceBundle (InputStream stream) throws IOException {
Properties properties = new Properties();
properties.load(stream);
lookup = new HashMap(properties);
}
`
So I think you should replace the above with the following initialization
method.
` public PropertyResourceBundle (Reader reader) throws IOException {
Properties properties = new Properties();
properties.load(reader);
lookup = new HashMap(properties);
}`
when you use this reader , you can set the charset to **utf-8**
