防止在SpringBoot / Jackson中进行原语到字符串的转换

import com.fasterxml.jackson.databind.ObjectMapper;

public class Main {
    public static void main(String[] args) throws Exception {
        // 创建ObjectMapper对象
        ObjectMapper objectMapper = new ObjectMapper();

        // 将原语类型转换为JSON字符串
        int intValue = 123;
        String intJson = objectMapper.writeValueAsString(intValue);
        System.out.println("intJson: " + intJson);

        double doubleValue = 3.14;
        String doubleJson = objectMapper.writeValueAsString(doubleValue);
        System.out.println("doubleJson: " + doubleJson);

        boolean booleanValue = true;
        String booleanJson = objectMapper.writeValueAsString(booleanValue);
        System.out.println("booleanJson: " + booleanJson);

        // 将JSON字符串转换为原语类型
        int intResult = objectMapper.readValue(intJson, int.class);
        System.out.println("intResult: " + intResult);

        double doubleResult = objectMapper.readValue(doubleJson, double.class);
        System.out.println("doubleResult: " + doubleResult);

        boolean booleanResult = objectMapper.readValue(booleanJson, boolean.class);
        System.out.println("booleanResult: " + booleanResult);
    }
}
