重现步骤
Test case
import com.alibaba.fastjson.JSON;
import com.alibaba.fastjson.parser.Feature;
import com.alibaba.fastjson.parser.ParserConfig;
import org.junit.Test;
import java.io.ByteArrayInputStream;
import java.io.IOException;
import java.io.InputStream;
import java.nio.charset.StandardCharsets;
import java.util.ArrayList;
import java.util.Arrays;
import java.util.Collection;
import java.util.Collections;
import static org.junit.Assert.assertEquals;
public class Test512 {
@Test
public void testParseObjectWithImmutableCollectionField() {
String jsonString = "{\"collectionField\": [1, 2, 3]}";
class ImmutableCollectionExample {
private final Collection<Integer> collectionField;
public ImmutableCollectionExample(Collection<Integer> collectionField) {
this.collectionField = Collections.unmodifiableCollection(new ArrayList<>(collectionField));
}
public Collection<Integer> getCollectionField() {
return collectionField;
}
}
try {
InputStream inputStream = new ByteArrayInputStream(jsonString.getBytes(StandardCharsets.UTF_8));
ImmutableCollectionExample result = JSON.parseObject(inputStream, StandardCharsets.UTF_8,
ImmutableCollectionExample.class, new ParserConfig(), Feature.SupportArrayToBean, Feature.DisableCircularReferenceDetect);
assertEquals(Arrays.asList(1, 2, 3), new ArrayList<>(result.getCollectionField()));
} catch (IOException e) {
// Handle or log the exception
}
}
}期待的正确结果
希望能够正常反序列化
