批处理处理金额小数点问题

NumberAdapter自定义转换器

/**
 * 用来处理小数点问题
 */
public class NumberAdapter extends TypeAdapter<String> {
    @Override
    public void write(JsonWriter out, String value) throws IOException {
        if (value == null) {
            out.nullValue();
        } else if (value.isEmpty()) {
            out.value("0");
        } else {
            out.value(value);
        }

    }

    @Override
    public String read(JsonReader in) throws IOException {
        JsonToken peek = in.peek();
        if (peek == JsonToken.NULL) {
            in.nextNull();
            return "0";
        }
        String value = in.nextString();
        BigDecimal bigDecimal = new BigDecimal(value);
        BigDecimal zero = BigDecimal.ZERO;
        if (bigDecimal.compareTo(zero) == 0) {
            return "0";
        }

        String result = bigDecimal.setScale(2, RoundingMode.DOWN).stripTrailingZeros().toPlainString();
//        Log.i("NumberAdapter", result);
        return result;

    }

}

　　

bean类使用

 

    @JsonAdapter(NumberAdapter.class)
    private String money;
