问题复现步骤:
1、提交表单,参数为:
2、接收参数类型为product实体类,如下
3、错误日志如下:
org.springframework.validation.BindException: org.springframework.validation.BeanPropertyBindingResult: 1 errors
Field error in object ‘product‘ on field ‘departureTime‘: rejected value [2020-02-10 09:00]; codes [typeMismatch.product.departureTime,typeMismatch.departureTime,typeMismatch.java.util.Date,typeMismatch]; arguments [org.springframework.context.support.DefaultMessageSourceResolvable: codes [product.departureTime,departureTime]; arguments []; default message [departureTime]]; default message [Failed to convert property value of type ‘java.lang.String‘ to required type ‘java.util.Date‘ for property ‘departureTime‘; nested exception is org.springframework.core.convert.ConversionFailedException: Failed to convert from type [java.lang.String] to type [java.util.Date] for value ‘2020-02-10 09:00‘; nested exception is java.lang.IllegalArgumentException]
问题分析:
从错误日志中可以看出,是product类的departureTime属性类型从String转换为Date转换错误。
解决方法:
实体类中加日期格式化注解
@DateTimeFormat(pattern="yyyy-MM-dd HH:mm")
private Date creationTime;
