java - Camel .contains() 不从属性文件中搜索值

Question

我需要在文件内搜索字符串，我使用了下面的java代码搜索字符串，它按我的预期工作，

.when(body().convertToString().contains("mytext"))

如果我需要更改搜索字符串，我必须再次重新编译代码，所以我尝试从属性文件加载搜索字符串，如下所示我在属性文件中定义了 findme='mytext' 但不会搜索带有“properties:{{findme}}”的字符串

.when(body().convertToString().contains("properties:{{findme}}"))

Answer 1

我认为应该是:

.when(body().convertToString().contains("{{findme}}"))

来自Apache Camel documentation on properties :

Syntax

The syntax to use Camel's property placeholder is to use {{key}} for example {{file.uri}} where file.uri is the property key. You can use property placeholders in parts of the endpoint URI's which for example you can use placeholders for parameters in the URIs.
