我正在为下面提到的方法编写一个Junit
有人可以建议适当的解决方案吗
在运行Junit后,我遇到了异常
java.lang.ArrayIndexOutOfBoundsException: -84
at org.apache.commons.codec.binary.Base64.isBase64(Base64.java:137)
at org.apache.commons.codec.binary.Base64.isArrayByteBase64(Base64.java:163)
我的考试班
public class DecodeToObjectTest extends TestCase {
public void testDecode() {
try {
String data="data";
ByteArrayOutputStream baos = new ByteArrayOutputStream();
ObjectOutputStream oos = new ObjectOutputStream(baos);
oos.writeObject(data);
// convert String into InputStream
DecodeToObject.decode(new String(baos.toByteArray()));
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (ClassNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
我需要测试的方法
public static
Object decode(
String input ) throws IOException,
ClassNotFoundException
{
Log log = LogFactory.getFactory().getInstance(
"com.avocent.cps.report.service" );
try
{
boolean c = Base64.isArrayByteBase64( input.getBytes() );
if(log.isDebugEnabled()){
log.debug( "DecodeToObject :Entering Helper Input: " + input ); }
byte[] data = Base64.decodeBase64( input.getBytes() );
ObjectInputStream ois = new ObjectInputStream(
new ByteArrayInputStream( data ) );
if(log.isDebugEnabled()){
log.debug( "DecodeToObject :Object Input stream ois: " + ois ); }
Object obj = null;
obj = ois.readObject();
if(log.isDebugEnabled()){
log.debug(
"DecodeToObject :Convering object to String: "
+ obj.toString() );
}
ois.close();
if(log.isDebugEnabled()){
log.debug(
"DecodeToObject :Decoded byte array to object successfully " );
}
return obj;
}
catch( ClassNotFoundException cnfe )
{
if(log.isErrorEnabled()){
log.error( "DecodeToObject : Error :" );
}
throw cnfe;
}
catch( IOException ioe )
{
if(log.isErrorEnabled()){
log.error( "DecodeToObject : Error :" );
}
throw ioe;
}
}

输入似乎不是Base64
编码的。试试这个:
boolean c = Base64.isArrayByteBase64( input.getBytes() );
if(log.isDebugEnabled()){
log.debug( "DecodeToObject :Entering Helper Input: " + input ); }
if(c) {
byte[] data = Base64.decodeBase64( input.getBytes() );
// your code
}
但我认为isArrayByteBase64()
正在抛出异常。 <{3}}
private static boolean isBase64(byte octect) {
if (octect == PAD) {
return true;
} else if (base64Alphabet[octect] == -1) {
return false;
} else {
return true;
}
}
静态字节数组base64Alphabet
在索引'-84'处没有元素,因此ArrayIndexOutOfBoundsException
。

而不是:
byte[] data = Base64.decodeBase64( input.getBytes() );
试试这个:
byte[] s = Base64.encodeBase64URLSafe(input.getBytes());
byte[] data = Base64.decodeBase64(s);

我遇到了同样的异常。 JUnit测试在我的IDE上传递,但在Maven构建时失败。
从
切换@RunWith(MockitoJUnitRunner.class)
到
@RunWith(PowerMockRunner.class)@PowerMockRunnerDelegate(SpringJUnit4ClassRunner.class)
解决了这个问题。
