【问题描述】:
我想这样发送请求:
- http://localhost:8080/reports/daily?start_date=2018-03-22&end_date=2018-03-24
我有一个错误:
“2018-05-31 15:40:29.623 WARN 11496 --- [nio-8080-exec-5] .w.s.m.s.DefaultHandlerExceptionResolver : 绑定请求失败 元素: org.springframework.web.method.annotation.MethodArgumentTypeMismatchException: 无法将“java.lang.String”类型的值转换为所需类型 'java.time.LocalDate';嵌套异常是 org.springframework.core.convert.ConversionFailedException: 失败 从类型 [java.lang.String] 转换为类型 [@org.springframework.web.bind.annotation.RequestParam @org.springframework.format.annotation.DateTimeFormat java.time.LocalDate] 的值'2018-03-22';嵌套异常是 java.lang.IllegalArgumentException:值的解析尝试失败 [2018-03-22] "
问题很明显,所以我找到了解决方案并更改了所有内容。我的方法:
@RequestMapping(path = "reports/daily", method = RequestMethod.GET,
consumes = MediaType.APPLICATION_JSON_VALUE)
public String getDailyReport(@RequestParam ("start_date")
@DateTimeFormat(iso = DateTimeFormat.ISO.DATE_TIME)
LocalDate startDate,
@RequestParam("end_date")
@DateTimeFormat(iso = DateTimeFormat.ISO.DATE_TIME)
LocalDate endDate) {
double totalDistance = 0.0;
double totalPrice = 0.0;
List<Transit> transits = transitService.getTransits(startDate, endDate);
for (Transit transit : transits) {
if (transit.getDistance() != null && transit.getPrice() != null) {
try {
totalDistance = totalDistance + transit.getDistance();
totalPrice = totalPrice + transit.getPrice();
} catch (NullPointerException e) {
e.fillInStackTrace().getMessage();
}
}
}
return "Total distance " + totalDistance + ", total price: " + totalPrice;
}
对我来说一切似乎都很好,我还在 pom 文件中添加了所需的依赖项。
