asd1245dss / ResourceBundleMessageSource.java
Created February 22, 2017 02:19
Because the default encoding for ResiurceBunldeMessageSource is ISO-8859-1,so you should define the defaultEncoding to UTF-8
(stream != null) {
String encoding = getDefaultEncoding();
if (encoding == null) {
encoding = "ISO-8859-1";
}
try {
return loadBundle(new InputStreamReader(stream, encoding));
}
finally {
stream.close();

asd1245dss / UnsafeSequenceTest.java
Created February 7, 2017 08:14
Java array clone is not deep clone,so all the elements in the array are same class
@Test
public void testArrayClone() {
UnsafeSequence[] unsafeSequences = new UnsafeSequence[10];
for (int i = 0; i < unsafeSequences.length; i++) {
unsafeSequences[i] = new UnsafeSequence();
}
UnsafeSequence[] unsafeSequencesClone = unsafeSequences.clone();
System.out.println(Arrays.toString(unsafeSequences));
System.out.println(Arrays.toString(unsafeSequencesClone));
