春天開機：MVC沒有返回視圖：thymeleaf＆春天數據

我試圖做一個簡單的MVC春季啓動應用程序，我有它在我的代碼當控制器爲返回的index.html要求」/」。

我不確定，但這不起作用。

SpringDataWebApplication.java

package com.demo.main; 

import org.springframework.boot.SpringApplication; 
import org.springframework.boot.autoconfigure.EnableAutoConfiguration; 
import org.springframework.boot.autoconfigure.SpringBootApplication; 
import org.springframework.boot.autoconfigure.domain.EntityScan; 
import org.springframework.boot.web.support.SpringBootServletInitializer; 
import org.springframework.context.annotation.ComponentScan; 
import org.springframework.data.jpa.repository.config.EnableJpaRepositories; 
import org.springframework.web.servlet.config.annotation.EnableWebMvc; 

@SpringBootApplication 
@EnableAutoConfiguration 
@EnableJpaRepositories("com.demo.repositories.*") 
@EntityScan("com.demo.entities.*") 
@ComponentScan(basePackages = {"com.demo.controller.*","com.demo.service.*"}) 
public class SpringDataWebApplication { 

    //TODO : Logging 


    public static void main(String[] args) { 

     SpringApplication.run(SpringDataWebApplication.class, args); 


    } 

}

HealthCHeckController.java

package com.demo.controller; 

import org.springframework.stereotype.Controller; 
import org.springframework.web.bind.annotation.RequestMapping; 

@Controller 
public class HealthCheckController { 

    @RequestMapping("/") 
    public String getSystemHealth() { 
     return "index"; 
    } 

}

UserRepository.java

package com.demo.repositories; 

import org.springframework.data.repository.CrudRepository; 
import org.springframework.stereotype.Repository; 

import com.demo.entities.UserEntity; 

@Repository 
public interface UserRepository extends CrudRepository<UserEntity, String> { 

}

的index.html

<!DOCTYPE html> 
<html xmlns:th="http://www.thymeleaf.org"> 
<head> 
<meta charset="ISO-8859-1"> 
<title>BlogPost URL check</title> 
</head> 
<body> 
<h1>HealthCHeck Working as desired</h1> 
</body> 
</html>

的Index.html是內/模板目錄按thymeleaf

的pom.xml

UserEntity.java：這還不是必需的，因爲我會一步一步我期待的只是對請求「/」的迴應，但我無法得到迴應。

package com.demo.entities;

你有什麼異常？ –

另外我想你的'UserEntity'類'id'應該是'Long'以支持CrudRepository。 [鏈接]（HTTP：//文檔。spring.io/spring-data/commons/docs/1.5.0.RELEASE/reference/html/repositories.html） –

事情是，我沒有得到任何異常。它的請求沒有到達控制器，當我在第一次看到http：// localhost：8080 – user641887

你一定要這樣說的：

http://docs.spring.io/spring-boot/docs/1.5.2.RELEASE/reference/htmlsingle/#boot-features-spring-mvc-static-content

您正在試圖打一個簡單的HTML頁面，這實際上是一個靜態的內容。從春天啓動文件：

默認春天啓動的任期將從一個名爲/靜態目錄（或/公共或/資源或/ META-INF /資源）在類路徑或從ServletContext的根靜態內容。

首先，這意味着你需要確保index.html頁面是靜態的文件夾下，位於在src /主/資源春季啓動靜態文件夾。

二，當試圖服務於春季啓動靜態內容，你需要和希望破滅的高速緩存，這意味着您的瀏覽器緩存您的舊的請求，併爲了看到你的變化正在發生，你需要把它添加到您的application.properties文件：

spring.resources.chain.strategy.content.enabled=true 
spring.resources.chain.strategy.content.paths=/**

看看這裏也：

Spring boot cannot load css from user folder

我沒有看到他的包結構的任何問題。他的'index.html'在'src/main/resources/templates'下。這就是百里香和春天的正常行爲。 – Patrick

主要問題不在於您指出的索引文件的位置，爲了破壞瀏覽器緩存，您應該將上述兩個語句添加到您的application.properties文件中。當然，在春季啓動時，如果索引文件位於適當的位置，這將有所幫助。請閱讀spring引導文檔的鏈接。 –

但他使用百里香作爲模板引擎。因此index.html的位置在模板下。 – Patrick
