Answer 1

如何使用自定义SearchTerm？它可以从Camel 2.11获得。来自Camel docs：
You can configure a searchTerm on the MailEndpoint which allows you to filter out unwanted mails.
Java示例：

// we just want the unseen mails which is not spam
SearchTermBuilder builder = new SearchTermBuilder();

builder.unseen().body(Op.not, "Spam").subject(Op.not, "Spam")
  // which was sent from either foo or bar
  .from("foo@somewhere.com").from(Op.or, "bar@somewhere.com");
  // .. and we could continue building the terms

SearchTerm term = builder.build();

Answer 2

这对我有用：

choice()
    .when(header("subject").isEqualTo("My Subject")).log("YES: ${header.subject}").to("direct:subroute1")
    .otherwise().log("NO: ${header.subject}").to("direct:subroute2");
