这篇文章主要介绍了SPRINGBOOT读取PROPERTIES配置文件数据过程详解,文中通过示例代码介绍的非常详细,对大家的学习或者工作具有一定的参考学习价值,需要的朋友可以参考下 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<Fruit> fruits;
private HashMap<String,Object> 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=Camel coffer.length=100.00 coffer.width=80.00 coffer.height=60.00 coffer.contains[0]=Raincoat coffer.contains[1]=trousers coffer.contains[2]=hat coffer.contains[3]=glove coffer.contains[4]=scarf coffer.contains[5]=hood coffer.fruits[0].fruitName=apricot coffer.fruits[0].fruitColor=yellow coffer.fruits[1].fruitName=plum coffer.fruits[1].fruitColor=green coffer.fruits[2].fruitName=pineapple coffer.fruits[2].fruitColor=yellow coffer.fruits[3].fruitName=watermelon coffer.fruits[3].fruitColor=green coffer.fruits[4].fruitName=strawberry coffer.fruits[4].fruitColor=red coffer.map.name=xiaomao coffer.map.age=22 coffer.map.gender=female 4、springbootApplicationTest
@SpringBootTest
class 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', Fruit{fruitName='watermelon', 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")
@RestController
public class SpringbootController {
@Value("${coffer.brand}")
private String brand;
@Value("${coffer.height}")
private Double height;
@RequestMapping("/test")
public String springbootTest() {
return brand+"====="+height;
}
}
