BigDecimal is a data type that can be used in financial and ERP applications where the precision of a number is important.BigDecimalis used to store the rounding of the numbers after arithmetic operations. It is an immutable type. BigDecimalis a class declared in thejava.mathpackage of the J...
基本类型、包装类、BigDecimal转String默认使用DecimalFormat格式化,@Mapping#numberFormat可以指定格式,Date转String默认使用SimpleDateFormat格式化,如默认格式不符要求,可以用,@Mapping可以指定格式。 enum和String:可直接转枚举定义的值,不支持MappingConstants.ANY_REMAINING BigDecimal(等)、基本数据类(包括包装类)和String: ...
In this article, we explored different methods to convert a Java string to a decimal number. We learned that we can use theDouble.parseDouble()method for basic conversions, theBigDecimalclass for precision and arithmetic operations, and theNumberFormatclass for more flexibility. Depending on the sp...

其实format函数有些类似c语言中printf函数,一些格式字符串与 C 类似,但已进行了某些定制,以适应 Java 语言,并且利用了其中一些特性。此方法提供了对布局对齐和排列的支持,以及对数值、字符串和日期/时间数据的常规格式和特定于语言环境的输出的支持。支持诸如 byte、BigDecimal 和 Calendar 等常见 Java 类型。

Yeah, I can arrange to share the code. I'm wondering if micrometer is the correct place for providing such a generic converter though. Imagine if it provided a Converter<String, BigDecimal>. Is there a chance of putting it in spring/spring-boot itself somewhere? That would be the ideal ...
