測試GWT序列化

Question

我想編寫一個JUnit測試來驗證是否可以通過GWT RPC過程成功地序列化一個特定的對象。我將如何做到這一點？我正在使用GWT 2.4和JUnit 4.8.1。

謝謝， - 戴夫

Answer 1

找到了答案。它是

@Test 
public void testObjSerializability() { 
    final Object obj = getObject(); 
    final HostedModeClientOracle hmco =new HostedModeClientOracle(); 
    final HasValues command = new ReturnCommand(); 
    final HasValuesCommandSink hvcs = new HasValuesCommandSink(command); 
    final CommandServerSerializationStreamWriter out = new CommandServerSerializationStreamWriter(hmco, hvcs); 
    try { 
     out.writeObject(obj); 
    } catch (Exception e) { 
     e.printStackTrace(System.err); 
     fail("Object couldn't be serialized:" + e.getMessage());    
    } 
} 

Answer 2

接受的答案不檢查無參數構造函數;如下：

public static void checkGwtSerializability(Object o) throws RuntimeException { 
    HostedModeClientOracle hmco = new HostedModeClientOracle(); 
    HasValues command = new ReturnCommand(); 
    HasValuesCommandSink hvcs = new HasValuesCommandSink(command); 
    CommandServerSerializationStreamWriter out = new CommandServerSerializationStreamWriter(hmco, hvcs); 

    try { 
     out.writeObject(o); 
    } catch (SerializationException e) { 
     throw new RuntimeException("Object not serializable: " + o + " Caused by: " + e.getMessage(), e); 
    } 

    try { 
     o.getClass().getDeclaredConstructor(); 
    } catch (NoSuchMethodException e) { 
     throw new RuntimeException("Object not serializable: " + o + " Caused by: " + e.getMessage(), e); 
    } 
}
