我正在尝试配置Maven使用Spring Boot与多模块。我对Maven和Spring Boot不是很熟悉,也不确定它们如何协同工作。因此,我开始创建一个简单的结构。一开始,我只想从一个模块开始。
myApp
|
|--web module
|----java
|------controller
|------Application.java (Main Methode)
|----resources
|------templates
|--------index.html
|------application.propperties
|------log4j2.json
|----webapp
|----pom.xml
|--pom.xml
这是我的父pom.xml:

在我的application.properties文件中,我添加了以下内容:
spring.view.prefix = /templates/
spring.view.suffix = .html
我的Application.java文件看起来像这样:
@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";
}
}
当我启动应用程序时,映射正在工作。
Mapped "{[/test]}" onto public java.lang.String saplication.controller.MainController.index(org.springframework.web.servlet.ModelAndView)
并且日志消息被显示出来
[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
但是当我输入http://localhost:8080/test时,我只能看到信息。
Whitelabel Error Page
This application has no explicit mapping for /error, so you are seeing this as a fallback.

There was an unexpected error (type=Not Found, status=404).
No message available
乍一看似乎一切正常,但我遇到的问题是Spring找不到我的index.html模板。
我真的不知道我的配置有什么问题!所以我需要你的帮助。

)。所以,你能否尝试创建它并再次检查? - kucing_terbang
