IDEA创建application.yml不是小绿叶图标（亲测有用）

**文章有点啰嗦，主要是我想将详细点，怕有些人不明白，不然你们自己从文章中间看就行了，我的IDEA是2019.2版本的，亲测有用**  
**开始我也是百度找其它博客的文章，结果我试了七八篇的博客，都没解决，所以自己摸索弄好了，赶紧写了篇博客**

# 首先添加pom依赖 #

<dependencies>
            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-web</artifactId>
            </dependency>
            
            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-actuator</artifactId>
            </dependency>
    
    
            
            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-devtools</artifactId>
                <scope>runtime</scope>
                <optional>true</optional>
            </dependency>
            <dependency>
                <groupId>org.projectlombok</groupId>
                <artifactId>lombok</artifactId>
                <optional>true</optional>
            </dependency>
            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-test</artifactId>
                <scope>test</scope>
            </dependency>
            <dependency>
                <groupId>org.mybatis</groupId>
                <artifactId>mybatis-spring</artifactId>
                <version>2.0.1</version>
                <scope>compile</scope>
            </dependency>
            
            <dependency>
                <groupId>mysql</groupId>
                <artifactId>mysql-connector-java</artifactId>
            </dependency>
    
    
        </dependencies>

**最后在刷新下项目，之后install下项目，如果这样子还没有变成小绿叶图标，那就接着看下面吧，反正我是这步就好了**

# 一、创建application.yml #

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80MzA4NTc5Nw_size_16_color_FFFFFF_t_70]![在这里插入图片描述][20200525145352350.png]

**创建完之后发现文件图标是YML的**

# 二、解决办法 #

目前不能提示的主要原因是IDEA没有把properties（或yml）文件关联到Spring，当成Spring文件管理。  
springboot基本的pom依赖加进去

<dependency>
                <groupId>cn.wwfww.springcloud</groupId>
                <artifactId>cloud-api-commons</artifactId>

            </dependency>
            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-devtools</artifactId>
                <scope>runtime</scope>
                <optional>true</optional>
            </dependency>
            <dependency>
                <groupId>org.projectlombok</groupId>

            </dependency>
            <dependency>

                <artifactId>spring-boot-starter-web</artifactId>
            </dependency>
            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-actuator</artifactId>
            </dependency>

## 1、File >>Project Structure 将项目关联到spring中 ##

## 2、File >>Project Structure 将项目resources文件变成配置文件夹 ##

**选中java文件夹，点击Sources，将java文件夹变成下图所示，这样才能在java这个文件夹里面新建java.class**

# 3、添加application.yml #

# 4、添加启动类 #

在启动类上加@SpringBootApplication注解提升没有这个包，点击下载

## 完美解决，application.yml变成绿叶了 ##
