如何引用駱駝路由中的電子郵件主題

Question

我試圖根據收到的電子郵件主題創建將消息發送到不同端點的路由。

如何引用RouteBuilder中的主題。

我試着標題（ 「主體」）。isEqualTo（...）和它不工作

Answer 1

有關使用自定義的搜索關鍵詞如何？它可以從駱駝2.11獲得。從駱駝文檔：
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

爲我工作：

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