在Redis中使用springboot时，如何将Java对象序列化为json，以及如何将Json序列化为对象？

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

import com.fasterxml.jackson.databind.ObjectMapper;

public class YourClass {
    public static void main(String[] args) throws Exception {
        // 创建一个Java对象
        YourObject obj = new YourObject();
        
        // 创建ObjectMapper对象
        ObjectMapper objectMapper = new ObjectMapper();
        
        // 将Java对象序列化为JSON字符串
        String json = objectMapper.writeValueAsString(obj);
        
        // 输出JSON字符串
        System.out.println(json);
    }
}

import com.fasterxml.jackson.databind.ObjectMapper;

public class YourClass {
    public static void main(String[] args) throws Exception {
        // JSON字符串
        String json = "{\"name\":\"John\", \"age\":30}";
        
        // 创建ObjectMapper对象
        ObjectMapper objectMapper = new ObjectMapper();
        
        // 将JSON字符串反序列化为Java对象
        YourObject obj = objectMapper.readValue(json, YourObject.class);
        
        // 输出Java对象的属性
        System.out.println("Name: " + obj.getName());
        System.out.println("Age: " + obj.getAge());
    }
}
