SPRINGBOOT读取PROPERTIES配置文件数据过程详解
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、Cofferentity
@Configuration
@ConfigurationProperties(prefix="coffer")
@PropertySource("classpath:config/coffer.properties")
publicclassCoffer{
privateStringbrand;
privateDoublelength;
privateDoublewidth;
privateDoubleheight;//省略了get/set方法
privateString[]contains;
privateArrayListfruits;
privateHashMapmap;
}
2、Fruitentity
@Configuration
@ConfigurationProperties(prefix="coffer.fruits")
@PropertySource("classpath:config/coffer.properties")
publicclassFruit{
privateStringfruitName;
privateStringfruitColor;//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
classSpringbootApplicationTests{
@Autowired
privateApplicationContextioc;
@Autowired
privateCoffercoffer;
@Test
publicvoidspringbootTest(){
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
publicclassSpringbootController{
@Value("${coffer.brand}")
privateStringbrand;
@Value("${coffer.height}")
privateDoubleheight;
@RequestMapping("/test")
publicStringspringbootTest(){
returnbrand+"====="+height;
}
}
