SPRINGBOOT读取PROPERTIES配置文件数据过程详解
人气:0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', 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") @RestController public class SpringbootController { @Value("${coffer.brand}") private String brand; @Value("${coffer.height}") private Double height; @RequestMapping("/test") public String springbootTest() { return brand+"====="+height; } }
