Apache camel Camel：在CXF端点配置中为布尔属性使用属性占位符

我喜欢在CXF端点定义中为布尔属性使用属性占位符。我在中阅读了有关占位符前缀的文档，但ik无法确定如何在端点配置中应用它们。字符串占位符工作正常。在下面的示例中，我使用布尔属性${ws-logging}，XML不会验证。如何在CXF端点配置中为布尔属性使用属性占位符

我认为您缺少一个模式引用和名称空间：blueprint cm。尝试添加它，如下面的示例所示

尝试了您的解决方案，但结果为阴性。看起来布尔类型属性仅接受实际布尔值，在上下文之外定义时不接受占位符。因此，仅接受值true、false、0或1。尝试解决方案时结果为负值。看起来布尔类型属性仅接受实际布尔值，在上下文之外定义时不接受占位符。因此，只接受值true、false、0或1。
