如何使用JAVA发送JSON？

   <groupId>com.fasterxml.jackson.core</groupId>
   <artifactId>jackson-databind</artifactId>
   <version>2.13.0</version>
</dependency>

public class Person {
    private String name;
    private int age;

    public Person(String name, int age) {
        this.name = name;
        this.age = age;
    }

    // Getter and Setter methods
}

import com.fasterxml.jackson.databind.ObjectMapper;

public class JsonExample {
    public static void main(String[] args) {
        Person person = new Person("John Doe", 30);

        try {
            ObjectMapper objectMapper = new ObjectMapper();
            String jsonString = objectMapper.writeValueAsString(person);
            System.out.println(jsonString);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

{"name":"John Doe","age":30}
