No enum constant org.apache.ibatis.type.JdbcType.jave.util.Date

在ibatis中,mapper层不需要关注这些参数而转到mybatis后如果字段值为空 必须设置jdbcType,如:

UnsatisfiedDependencyException:Unsatisfied dependency expressed through field 'blotService'

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'blotController': Unsatisfied dependency expressed through field 'blotService'; 



@SpringBootApplicat

Spring报错-‘artifactId‘ with value ‘xxxx‘ does not match a valid id pattern.错误

错误原因: POM文件为gav格式, 不允许中文字符或空格 ,仅使用下划线,数字,字母 将artifactId属性值改为符合要求的形式即可 1 2020_11_15
