Spring Boot:如何解析由对象数组组成的JSON，并使用path变量获取特定值？

import com.fasterxml.jackson.databind.ObjectMapper;

public class JsonParser {
    public static void main(String[] args) {
        String json = "[{\"name\":\"John\",\"age\":30},{\"name\":\"Jane\",\"age\":25}]";

        try {
            ObjectMapper objectMapper = new ObjectMapper();
            Person[] persons = objectMapper.readValue(json, Person[].class);

            for (Person person : persons) {
                System.out.println("Name: " + person.getName());
                System.out.println("Age: " + person.getAge());
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

class Person {
    private String name;
    private int age;

    // getters and setters
}

import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class MyController {
    @GetMapping("/users/{id}")
    public String getUserById(@PathVariable("id") int id) {
        // 根据id获取用户信息的逻辑
        return "User ID: " + id;
    }
}
