Springboot入门实战, 使用@Value
今天开始最简单的Springboot应用
entity.Book
package com.draymonder.amor.entity;
import java.util.List;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.stereotype.Component;
@Component
public class Book {
@Value("${book.name}")
private String name;
@Value("${book.author}")
private String author;
@Value("${book.price}")
private Double price;
@Value("#{'${book.love}'.split(',')}")
private List<String> love;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getAuthor() {
return author;
}
public void setAuthor(String author) {
this.author = author;
}
public Double getPrice() {
return price;
}
public void setPrice(Double price) {
this.price = price;
}
@Override
public String toString() {
return "Book{" +
"name='" + name + '\'' +
", author='" + author + '\'' +
", price=" + price +
", love=" + love +
'}';
}
}
web.BookController
package com.draymonder.amor.web;
import com.draymonder.amor.entity.Book;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;
@RestController
public class BookController {
@Autowired
Book book;
@GetMapping("/book")
public String book() {
return book.toString();
}
}
resources/applcation.yml
server:
port: 8080
book:
name: amor
author: draymonder
price: 50
love: a, b, c
访问url localhost:8080/book
展示结果
Book{name='amor', author='draymonder', price=50.0, love=[a, b, c]}
