Saxon非常擅长错误报告。它的验证器首先为您提供可理解的消息。
我使用了骆驼式验证器,我正在从模式验证中捕获错误,比如:
org.xml.sax.SAXParseException: cvc-minLength-valid: Value '' with length = '0' is not facet-valid with respect to minLength '1' for type
有什么工具可以将这些错误映射为更漂亮的语句吗?我总是可以迭代错误,对它们进行拆分,并准备自定义映射程序,但也许还有比这更好的东西?:)
这是一条SAX错误消息,它似乎已经非常清楚地说明了,但请参阅ErrorHandler和DefaultHandler以自定义它。
我已经通过骆驼式验证组件用xsd创建了验证
<to uri="validator:xsd/myValidator.xsd"/>
然后我在doTry块中使用了doCatch来捕获异常:
<doCatch>
<exception>org.apache.camel.ValidationException</exception>
<log message="catch exception ${body}" loggingLevel="ERROR" />
<process ref="schemaErrorHandler"/>
</doCatch>
在那之后,我写了自定义骆驼处理器,它工作得很好:)
public class SchemaErrorHandler implements Processor {
private final String STATUS_CODE = "6103";
private final String SEVERITY_CODE = "2";
@Override
public void process(Exchange exchange) throws Exception {
Map<String, Object> map = exchange.getProperties();
String statusDesc = "Unknown exception";
if (map != null) {
SchemaValidationException exception = (SchemaValidationException) map.get("CamelExceptionCaught");
if (exception != null && !CollectionUtils.isEmpty(exception.getErrors())) {
StringBuffer buffer = new StringBuffer();
for (SAXParseException e : exception.getErrors()) {
statusDesc = e.getMessage();
buffer.append(statusDesc);
}
statusDesc = buffer.toString();
}
}
Fault fault = new Fault(new Message(statusDesc, (ResourceBundle) null));
fault.setDetail(ErrorUtils.createDetailSection(STATUS_CODE, statusDesc, exchange, SEVERITY_CODE));
throw fault;
}
}
