在Java语言中将BigDecimal字段返回为JSON字符串值

public class Product {
    private BigDecimal price;

    public BigDecimal getPrice() {
        return price;
    }

    public void setPrice(BigDecimal price) {
        this.price = price;
    }
}

import com.fasterxml.jackson.databind.ObjectMapper;

public class Main {
    public static void main(String[] args) throws Exception {
        Product product = new Product();
        product.setPrice(new BigDecimal("10.99"));

        ObjectMapper objectMapper = new ObjectMapper();
        String json = objectMapper.writeValueAsString(product);

        System.out.println(json);
    }
}

{"price":10.99}
