Maven Spring Boot多模塊

我試圖配置Maven以使用多模塊Spring Boot。我是Maven和Spring Boot Stuff的新手，我不確定這是如何協同工作的。所以我開始創建一個簡單的結構。一開始我想從一個模塊開始。Maven Spring Boot多模塊

</project>

要我application.propperties我添加

spring.view.prefix = /templates/ 
spring.view.suffix = .html

而我的Application.java看起來像這樣：

@SpringBootApplication 
public class Application { 

    public static void main(String[] args) { 
     System.out.println("Hallo"); 
     SpringApplication.run(SaplicationApplication.class, args); 
    } 
}

我的控制器

@Controller 
public class MainController { 

    private static final Logger logger = LogManager.getLogger(MainController.class.getName()); 

    @RequestMapping("/test") 
    public String index(ModelAndView modelAndView) { 
     logger.info("/test"); 
     logger.debug("Hello world - debug log"); 
     logger.info("Hello world - info log"); 
     logger.warn("Hello world - warn log"); 
     logger.error("Hello world - error log"); 
     return "index"; 
    } 

}

當我開始映射工作

Mapped "{[/test]}" onto public java.lang.String saplication.controller.MainController.index(org.springframework.web.servlet.ModelAndView)

的應用程序和日誌消息顯示

[INFO ] 2015-10-06 08:41:37.477 [http-nio-8080-exec-1] MainController - /test 
[INFO ] 2015-10-06 08:41:37.478 [http-nio-8080-exec-1] MainController - Hello world - info log 
[WARN ] 2015-10-06 08:41:37.478 [http-nio-8080-exec-1] MainController - Hello world - warn log 
[ERROR] 2015-10-06 08:41:37.478 [http-nio-8080-exec-1] MainController - Hello world - error log

但是當我輸入http://localhost:8080/test我剛看到消息

Whitelabel Error Page 

This application has no explicit mapping for /error, so you are seeing this as a fallback. 

Tue Oct 06 08:41:37 CEST 2015 
There was an unexpected error (type=Not Found, status=404). 
No message available

在第一種觀點，似乎一切正常，但問題女巫我是春沒有找到我的index.html模板。

我readlly不知道我的配置中出了什麼問題！所以我需要你的幫助。

你可以用[http：// localhost：8080//test]（http：// localhost：8080//test）以及maven的快照名稱來嘗試它。 [http：// localhost：8080//test]（http：// localhost：8080//test） – Patrick

你有你的應用程序在github或者別的地方？ –

看起來像jsp頁面不存在（'index.jsp'）。所以，你可以嘗試創建它並再次檢查它嗎？ –

進行這些更改您的Application.java

@SpringBootApplication 
    public class Application extends SpringBootServletInitializer { 

     @Override 
     protected SpringApplicationBuilder configure(SpringApplicationBuilder application) { 
      return application.sources(Application.class); 
     } 

     public static void main(String[] args) throws Exception { 
      SpringApplication.run(Application.class, args); 
     } 

    }

SpringBootServletInitializer

這需要運行的Web應用程序。這將啓用servlet容器並將您的應用程序綁定到servlet容器。

更新： -

要運行的主模塊（Web模塊），你必須轉到在該目錄之後，使用mvn spring-boot:run命令運行項目。

例子： - [我@ linuxbox對myApp] $ cd /web2. [我@ linuxbox網] $ mvn spring-boot:run

只有在構建戰爭並將其部署到獨立容器時才需要這樣做。如果您遵循使用嵌入式容器的推薦和默認方法，則無需此操作。 –

把你的資源文件夾src/main/resources在Web模塊內。這是資源的默認Maven結構。

解決方案：將您的IDE的工作DIR更改爲您的模塊，因爲spring-boot嵌入tomcat使用頂級路徑加上您定義的路由web根目錄。
