JAVA利用application.yml配置文件获得类与属性信息

By | 2019年2月25日

话不多说,直接给大家上代码:

实体类信息br/>**@ConfigurationProperties(prefix=”mycar”)**
@Component
public class CarEntity {

public CarEntity() {
// TODO Auto-generated constructor stub
}

private String carNo;
private String carName;
private String color;
private String carProductDate;
private double price;
public String getCarNo() {
return carNo;
}
public void setCarNo(String carNo) {
this.carNo = carNo;
}
public String getCarName() {
return carName;
}
public void setCarName(String carName) {
this.carName = carName;
}
public String getColor() {
return color;
}
public void setColor(String color) {
this.color = color;
}
public String getCarProductDate() {
return carProductDate;
}
public void setCarProductDate(String carProductDate) {
this.carProductDate = carProductDate;
}
public double getPrice() {
return price;
}
public void setPrice(double price) {
this.price = price;
}
@Override
public String toString() {
return “CarEntity [carNo=” + carNo + “, carName=” + carName + “, color=” + color + “, carProductDate=”
+ carProductDate + “, price=” + price + “]”;
}
}
application.yml文件属性配置信息
mycar:
carNo: 渝A88866
carName: 法拉利
color: Red
carProductDate: 2019-01-01
price: 500000br/>直接获取单个属性
@Value(“${mycar.carNo}”)
private String carNo;

Controller获取属性类信息
@Autowired
private CarEntity carInfo;

@GetMapping(value=”books/{userid}”)
public String detail(@PathVariable Integer userid,Model m) {
m.addAttribute(“bookid”, userid);
UserEntity user = new UserEntity();
user.setId(userid);
user.setUsername(“TOM JACK(王五)”);
List<UserEntity> users = userMapper.getAllUser();
m.addAttribute(“user”, user);
**m.addAttribute(“CarInfo”, carInfo.toString());**
return “bookshop”;
}

页面展示
<p>
<strong>CarInfo:</strong>
<span th:text=”${CarInfo}”></span>
</p>
