                    @ApiParam(value = "FirstValue", required = true, type = "string", defaultValue = "0") @RequestParam(value = "firstValue", required = true) Integer x,
                    @ApiParam(value = "SecondValue", required = true, type = "string", defaultValue = "0") @RequestParam(value = "secondValue", required = true) Integer y) {

Answer 1

删除旧版本（1.5.20）并添加新版本。

字体：github issues

annual_salary = float(input('Enter your annual salary:')) #120000

portion_saved = float(input('Enter the percent of your salary to save, as a decimal:')) #.05

total_cost = float(input('Enter the cost of your dream home:')) #500000

semi_annual_raise = float(input('Enter the semiannual raise, as a decimal: ')) #.03

portion_down_payment = .25 * total_cost
current_savings = 0
annual_return_rate = .04

portion_saved_monthly = annual_salary / 12 * portion_saved

current_savings = current_savings + portion_saved_monthly

month = 1
while current_savings < portion_down_payment:
    current_savings += (current_savings * annual_return_rate / 12) + portion_saved_monthly
    month += 1
    if month % 6 == 0:
        annual_salary += annual_salary * semi_annual_raise
        portion_saved_monthly = annual_salary / 12 * portion_saved
        current_savings += (current_savings * annual_return_rate / 12) + portion_saved_monthly

print('Number of months: ', month)

Answer 2

这不是错误，只是严重性警告的日志，可通过使用

来忽略

logging.level.io.swagger.models.parameters.AbstractSerializableParameter=error

关于application.properties。根据我的经验，他不会为整数设置值0（我认为这是因为int类型的默认值）。

关于将类型显示为ref，这是因为integer并非接受的值之一。对于java.lang.Integer或原始int，应在swagger中使用类型“ int”。我接受的其他值包括：“ long”（对于java.lang.Long和long），“ bigInteger”（对于java.math.BigInteger），当然还有“ string”（对于java.lang.String）。 / p>

除字符串外，不支持@ApiParam类型
