apache camel spring dsl检查body是否包含字符串

Question

我想检查一下：

<simple>${body} contains 'verification'</simple>

身体是json：

{"verification": {"email": "bb@wp.pl", "code": "1234"}}

但这种情况不起作用。我也试过了：

<simple>${body} contains &#39;verification&#39;</simple>
<simple>${bodyAs(String)} contains 'verification'</simple>
<simple>${body.verification} != null</simple>

你能告诉我什么吗？

Answer 1

我猜身体可能不是字符串，然后尝试

<simple>${bodyAs(String)} contains 'verification'</simple>

顺便问一下你使用的是什么版本的Camel？

Answer 2

实际上这个案例：

<simple>${bodyAs(String)} contains 'verification'</simple>

没有工作原因： In Camel the message body can be of any types. Some types are safely readable multiple times, and therefore do not 'suffer' from becoming 'empty'.

It fixes by Stream caching
