@Value

 

使用@Value一个个字段给值

@Component
public class Man {
    @Value("${person.lastName}")
    private String lastName;
    @Value("12")
    private Integer age;
    @Value("false")
    private Boolean boss;

从application.properties里取值:

application.properties:

person.lastName = lisi person.age = 1

运行看结果:

@RestController
public class FirstController {

    @Autowired
    Man man;


    @RequestMapping("/hello")
    public String helloWorld() {
        return man.toString();
    }
}

 

 

 

 

 

 也可以直接对一个字段直接绑定使用:

application.properties:

person.lastName = lisi
person.age = 1

java:

@RestController
public class FirstController {

    @Value("${person.age}")
    private Integer age;


    @RequestMapping("/hello")
    public String helloWorld() {
        return "age"+age;
    }
}

结果:
