Java-Spring-Boot-variable

Spring Boot

之前在 Java 已經處理了 route, method 的問題

接下來要處理使用 API 溝通時要傳遞參數的時候要如何實作？

• Path Variable
• Query String Variable
• Request Body Variable

Path Variable

package com.example.demo.springbootdemo.web;
import org.springframework.web.bind.annotation.*;

import java.util.HashMap;
import java.util.Map;

@RestController
@RequestMapping("/api")
public class HelloController {
    @GetMapping("/books/{id}")
    public Object getOne(@PathVariable long id) {
        Map<String, Object> book = new HashMap<>();
        book.put("id", id);
        book.put("name", "new book");
        book.put("number", "123jkda");
        return book;
    }
}
