執行起來沒報錯，但是開啟瀏覽器輸入地址http://localhost:8080/greeting出現以下頁面

檢查地址沒問題，核對jar包也正確。google,有說少jar包，按照回答新增以後也無濟於事。折騰了一會找到了原因

竟然時目錄檔案結構問題，最後附上官網說明http://docs.spring.io/spring-boot/docs/current-SNAPSHOT/reference/htmlsingle/#using-boot-structuring-your-code

      14.2 Locating the main application class
     
    
    2. 
   
  2. 
    
     
    
    
     
      We generally recommend that you locate your main application class in a root package above other classes. The @EnableAutoConfiguration annotation is often placed on your main class, and it implicitly defines a base “search package” for certain items. For example, if you are writing a JPA application, the package of the @EnableAutoConfiguration annotated class will be used to search for @Entity items.
