### 1.新建一个maven工程springboot，添加相关依赖，pom文件类容如下： ###

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
      xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
      <modelVersion>4.0.0</modelVersion>
    
      <groupId>com.szcatic</groupId>
      <artifactId>springboot</artifactId>
      <version>0.0.1-SNAPSHOT</version>
      <packaging>jar</packaging>
    
      <name>springboot</name>
      <url>http://maven.apache.org</url>
      
      	<parent>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-parent</artifactId>
            <version>2.1.0.RELEASE</version>
        </parent>
        <dependencies>
            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-web</artifactId>
            </dependency>
            <dependency>
    			<groupId>org.springframework.boot</groupId>
    			<artifactId>spring-boot-starter-test</artifactId>
    			<scope>test</scope>
    		</dependency>
            
    		<dependency>
    		    <groupId>org.junit.jupiter</groupId>
    		    <artifactId>junit-jupiter-engine</artifactId>
    		    <scope>test</scope>
    		</dependency>
    		<dependency>
    		    <groupId>org.junit.platform</groupId>
    		    <artifactId>junit-platform-runner</artifactId>
    		    <scope>test</scope>
    		</dependency>
        </dependencies>
        <properties>
            <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
            <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
            <java.version>1.8</java.version>
        </properties>
        <build>
            <plugins>
                <plugin>
                    <groupId>org.springframework.boot</groupId>
                    <artifactId>spring-boot-maven-plugin</artifactId>
                    <configuration>
    	                <source>1.8</source>
    	                <target>1.8</target>
    	            </configuration>
                </plugin>
            </plugins>
        </build>
    </project>

### 2.在/src/main/resources/资源文件夹下新建文件config.properties，类容如下： ###

com.szcatic.title=标题
    com.szcatic.name=名字
    com.szcatic.description=${com.szcatic.title}${com.szcatic.name}描述

### 3.创建配置文件类实体CustomizeProperties.java ###

package com.szcatic.properties;
    
    import org.springframework.beans.factory.annotation.Value;
    import org.springframework.context.annotation.PropertySource;
    import org.springframework.stereotype.Component;
    
    @Component
    @PropertySource(value = "classpath:config.properties", encoding = "UTF-8")
    public class CustomizeProperties {
    	
    	@Value("${com.szcatic.name}")
    	private String name;
    	
    	@Value("${com.szcatic.title}")
    	private String title;
    	
    	@Value("${com.szcatic.description}")
    	private String description;
    	
    	public String getName() {
    		return name;
    	}
    
    	public void setName(String name) {
    		this.name = name;
    	}
    
    	public String getTitle() {
    		return title;
    	}
    
    	public void setTitle(String title) {
    		this.title = title;
    	}
    
    	public String getDescription() {
    		return description;
    	}
    
    	public void setDescription(String description) {
    		this.description = description;
    	}
    	
    	
    }

### 4.创建应用程序入口Application.java ###

package com.szcatic;
    
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    import org.springframework.context.annotation.ComponentScan;
    import org.springframework.web.bind.annotation.RequestMapping;
    
    @ComponentScan(basePackages = {"com"})
    @SpringBootApplication
    public class Application {
    	
    	public static void main(String[] args) {
    		SpringApplication.run(Application.class, args);
    	}
    	
    	@RequestMapping("/hello")
        public String getHello() {
            return "Hello World";
        }
    }

###  5.创建测试类 ###

package com.szcatic.test;
    
    import org.junit.Assert;
    import org.junit.jupiter.api.Test;
    import org.junit.jupiter.api.extension.ExtendWith;
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.boot.test.context.SpringBootTest;
    import org.springframework.context.annotation.Configuration;
    import org.springframework.test.context.junit.jupiter.SpringExtension;
    
    import com.szcatic.Application;
    import com.szcatic.properties.CustomizeProperties;
    
    @Configuration
    @ExtendWith(SpringExtension.class)
    @SpringBootTest(classes = Application.class)
    public class CustomizePropertiesTest {
    	
    	@Autowired
    	private CustomizeProperties properties;
    	
    	@Test
    	void testGet() {
    		Assert.assertEquals(properties.getName(), "名字");
    		Assert.assertEquals(properties.getTitle(), "标题");
    		Assert.assertEquals(properties.getDescription(), "标题名字描述");
    		System.out.println("测试成功");
    	}
    	
    }

### 6.运行测试方法testGet，获得测试结果 ###
