Springboot注解@Value读取配置文件参数_spring value获取参数

1、读取application.ym文件配置直接在类属性上@Value("${application.yml里的字段}")；

2、读取自定义Properties文件的配置：

    在类上使用@PropertySource（可同时读取多个properties文件）；

例子：

自定义两个properties文件：

wkx.properties:

wkx2.properties:

Prop实体类：

@Component
@PropertySource(value={"classpath:wkx.properties","classpath:wkx2.properties"})
//@PropertySource("classpath:wkx.properties")
public class Prop {
    @Value("${my.wkx.name}")
    private String name;
    @Value("${demo.password}")
    private String password;
    @Value("${my.wkx2.address}")
    private String address;
    public String getAddress() {
        return address;
    }
 
    public void setAddress(String address) {
        this.address = address;
    }
    public String getName() {
        return name;
    }
 
    public void setName(String name) {
        this.name = name;
    }
 
    public String getPassword() {
        return password;
    }
 
    public void setPassword(String password) {
        this.password = password;
    }
 
}

测试接口：

@RestController
@RequestMapping("/wkx1")
public class PropController {
    @Autowired
    private Prop prop;
 
    @GetMapping("/test")
    public String show() {
        return "username" +":"+ prop.getName() +"--"+ "password" +":"+ prop.getPassword()+"--"+
                "address"+":"+prop.getAddress();
    }
}

测试结果：
