1.创建maven工程，在pom文件中添加依赖

<parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>1.5.9.RELEASE</version> </parent> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <!-- 单元测试使用 --> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> </dependency> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <scope>test</scope> </dependency> </dependencies>

2.创建项目启动类 StartApplication.java

package com.kelly.controller;import org.springframework.boot.SpringApplication;import org.springframework.boot.autoconfigure.EnableAutoConfiguration;import org.springframework.context.annotation.ComponentScan;import org.springframework.context.annotation.Configuration;@Configuration@EnableAutoConfiguration //自动加载配置信息@ComponentScan("com.kelly")//使包路径下带有注解的类可以使用@Autowired自动注入public class StartApplication { public static void main(String[] args) { SpringApplication.run(StartApplication.class, args); }}package com.kelly.controller;import org.springframework.boot.SpringApplication;import org.springframework.boot.autoconfigure.EnableAutoConfiguration;import org.springframework.context.annotation.ComponentScan;import org.springframework.context.annotation.Configuration;@Configuration@EnableAutoConfiguration //自动加载配置信息@ComponentScan("com.kelly")//使包路径下带有注解的类可以使用@Autowired自动注入public class StartApplication { public static void main(String[] args) { SpringApplication.run(StartApplication.class, args); }}package com.kelly.controller;import org.springframework.beans.factory.annotation.Value;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.ResponseBody;@Controllerpublic class FirstController { @Value("${test.name}") private String name; @Value("${test.password}") private String password; @RequestMapping("/") @ResponseBody String home() { return "Hello Springboot!"; } @RequestMapping("/hello") @ResponseBody String hello() { return "name: " + name + ", " + "password: " + password; }}

5.打开浏览器，输入 http://localhost:8081/springboot/hello 即可看到结果

6.使用java bean的方式读取自定义配置文件 define.properties

　　DefineEntity.java

package com.kelly.entity;import org.springframework.boot.context.properties.ConfigurationProperties;import org.springframework.context.annotation.PropertySource;import org.springframework.stereotype.Component;@Component@ConfigurationProperties(prefix="defineTest")@PropertySource("classpath:define.properties")public class DefineEntity { private String pname; private String password; public String getPname() { return pname; } public void setPname(String pname) { this.pname = pname; } public String getPassword() { return password; } public void setPassword(String password) { this.password = password; }}SecondController.javapackage com.kelly.controller;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.ResponseBody;import com.kelly.entity.DefineEntity;@Controllerpublic class SecondController { @Autowired DefineEntity defineEntity; @RequestMapping("/define") @ResponseBody String define() { return "test.name:" + defineEntity.getPname() + ", test.password:" + defineEntity.getPassword(); }}

7.打开浏览器，访问 http://localhost:8081/springboot/define，可以看到输出结果

补充：我的项目的目录结构
