问题描述
我们有一个骆驼网关服务，
-
以JSON接收请求，将其转换为SOAP请求并调用 SOAP服务。
-
并在收到SOAP响应后将其转换为JSON并发送 回到呼叫者服务。
现在，在将对POJO的SOAP响应转换为JSON时，它会抛出异常 在下面，
com.ctc.wstx.exc.WstxLazyException: [com.ctc.wstx.exc.WstxLazyException] Invalid UTF-8 middle byte
0x26 (at char #8412,byte #7999)
SOAP响应带有一些 UTF字符，例如‖“，这引起了问题。 如何处理或忽略这些UTF字符并转换为JSON？
骆驼代码：Routes.java
private void getPlanDetailsRequestRoute(JacksonDataFormat jacksonDataformat,SoapJaxbDataFormat soapJaxbDataFormat,DataFormat jaxb) {
from("servlet:/PlanDetailsRequestService?matchOnUriPrefix=true").unmarshal(jacksonDataformat).to("dozer:transformOrder?mappingFile=DozerMapping.xml&sourceModel=com.ong.vx.gatewayservice.dto.PlanRecord&targetModel=com.ong.vx.gatewayservice.wsdl.GetPlanDetailsRequest").marshal(soapJaxbDataFormat)
.to("bean:SoapEnvelopeWrapper?method=process").to(WS_URI).choice()
.when(header(Exchange.HTTP_RESPONSE_CODE).isEqualTo(500)).to("bean:ExceptionExtracter?method=process")
.endChoice().otherwise().unmarshal(soapJaxbDataFormat).end().unmarshal(jaxb).marshal().json(JsonLibrary.Jackson)
.setHeader(Exchange.CONTENT_TYPE,constant("application/json"));
}

解决方法
您收到类似SOAP响应的UTF-8字符的声音的异常编码为ISO-8859-1，而不是UTF-8。另请参见this answer for details。
您是否检查了响应的编码正确（根据XML声明？）并且响应的charset标头正确？如果没有，那么最好修复SOAP服务（源）。
如果您无法控制源代码，那么最好的选择就是采取变通办法。例如，在进行转换之前，使用正则表达式用正确的字符替换分散注意力的字符。
