Spring Integration：接收消息时出现异常

Question

在我们的 Spring Integration 应用程序中，当接收到消息时，会引发异常并且转换器不会接收到消息。 我认为这可能是由于消息的内容，因为字符串类型的消息被正确处理。

以下是该消息类型的转换器的签名：

@Transformer
public String transform(Message inboundMessage){

也试过

@Transformer
public String transform(Byte[] inboundMessage){

但在这两种情况下，都会引发以下异常：

2013-10-14 07:21:33,547 D|DefaultMessageListenerContainer         |Received message of type [class com.solacesystems.jms.message.SolTextMessage] from consumer [Cached JMS MessageConsumer: com.solacesystems.jms.SolQueueReceiver@13b5500] of session [Cached JMS Session: com.solacesystems.jms.SolSession@1fa0f19]

非常感谢任何帮助

它没有到达变压器那么远。当 Spring 调用 getText 时，问题出在 Solace 库中...

java.lang.RuntimeException: UTF-8 format error
at com.solacesystems.common.util.UTF8Util.getStringFromUTF8(UTF8Util.java:272) ~[sol-common-6.0.0.146.jar:na]
at com.solacesystems.jms.message.SolTextMessage.load(SolTextMessage.java:82) ~[sol-jms-6.0.0.146.jar:na]
at com.solacesystems.jms.message.SolTextMessage.getText(SolTextMessage.java:69) ~[sol-jms-6.0.0.146.jar:na]
at org.springframework.jms.support.converter.SimpleMessageConverter.extractStringFromMessage(SimpleMessageConverter.java:177) ~[spring-jms-3.1.2.RELEASE.jar:3.1.2.RELEASE]
...

看起来库认为数据是 UTF-8 格式，但实际上不是。
