一.使用@ConfigurationProperties来读取

1、Coffer entity

@Configuration@ConfigurationProperties(prefix = "coffer")@PropertySource("classpath:config/coffer.properties")public class Coffer {  private String brand;  private Double length;  private Double width;  private Double height;          //省略了get/set方法  private String[] contains;  private ArrayList fruits;  private HashMap map;}

2、Fruit entity

@Configuration@ConfigurationProperties(prefix = "coffer.fruits")@PropertySource("classpath:config/coffer.properties")public class Fruit {  private String fruitName;  private String fruitColor;        //省略了get/set方法 }

3、coffer.properties

coffer.brand=Camelcoffer.length=100.00coffer.width=80.00coffer.height=60.00coffer.contains[0]=Raincoatcoffer.contains[1]=trouserscoffer.contains[2]=hatcoffer.contains[3]=glovecoffer.contains[4]=scarfcoffer.contains[5]=hoodcoffer.fruits[0].fruitName=apricotcoffer.fruits[0].fruitColor=yellowcoffer.fruits[1].fruitName=plumcoffer.fruits[1].fruitColor=greencoffer.fruits[2].fruitName=pineapplecoffer.fruits[2].fruitColor=yellowcoffer.fruits[3].fruitName=watermeloncoffer.fruits[3].fruitColor=greencoffer.fruits[4].fruitName=strawberrycoffer.fruits[4].fruitColor=redcoffer.map.name=xiaomaocoffer.map.age=22coffer.map.gender=female

4、springbootApplicationTest

@SpringBootTestclass SpringbootApplicationTests {  @Autowired  private ApplicationContext ioc;  @Autowired  private Coffer coffer;  @Test  public void springbootTest(){    System.out.println(coffer);  }}

5、result

Coffer{　　brand='Camel', 　　length=100.0, 　　width=80.0, 　　height=60.0, 　　contains=[Raincoat, trousers, hat, glove, scarf, hood], 　　fruits=[　　　　　　 Fruit{fruitName='apricot', fruitColor='yellow'}, 　　　　　　 Fruit{fruitName='plum', fruitColor='green'}, 　　　　　　 Fruit{fruitName='pineapple', fruitColor='yellow'}, 　　　　　　 Fruit{fruitName='watermelon', fruitColor='green'}, 　　　　　　 Fruit{fruitName='strawberry', fruitColor='red'}　　　　　　], 　　map={age=22, gender=female, name=xiaomao}}

二、使用@Value来读取

在springTest中无法使用@Value来读取配置属性,需要放到Controller中去读取

@PropertySource("classpath:config/coffer.properties")@RestControllerpublic class SpringbootController {  @Value("${coffer.brand}")  private String brand;  @Value("${coffer.height}")  private Double height;  @RequestMapping("/test")  public String springbootTest() {    return brand+"====="+height;  }}
