org.springframework.boot spring-boot-starter-parent 1.5.9.RELEASE org.springframework.boot spring-boot-starter-web org.springframework.boot spring-boot-starter-test junit junit test
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; @Controller public 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.java package 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; @Controller public 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
