jackson-dataformat-csv:无法序列化LocalDate [英] jackson-dataformat-csv: cannot serialize LocalDate

问题描述

当我尝试序列化包含本地日期的对象时，出现以下错误:

When I try to serialize object containing Local date, I get following error:

csv生成器不支持属性的对象值

csv generator does not support object values for properties

我启用了WRITE_DATES_AS_TIMESTAMPS的JSR-310模块，并且可以毫无问题地将同一对象转换为JSON.

I have JSR-310 module enabled, with WRITE_DATES_AS_TIMESTAMPS and I can convert the same object to JSON without problem.

目前，我诉诸于将对象映射到另一个仅字符串对象，但这是s废和浪费的.

For now I resorted to mapping the object to another, string only object, but it's decadent and wasteful.

Jackson csv映射器是否可以确认localDates?我是否应该以某种方式启用专门用于csv映射器的JSR-310?

Is there a way for Jackson csv mapper to acknowledge localDates? Should I somehow enable JSR-310 specifically for csv mapper?

推荐答案

由于在架构之后配置了映射器，因此我遇到了同样的问题.确保您使用的是杰克逊及其模块的最新版本.这段代码对我有用:

I had the same problem because of configuring mapper after schema. Make sure you are using the latest verson of jackson and its modules. This code works for me:

final CsvMapper mapper = new CsvMapper();
mapper.findAndRegisterModules();
mapper.configure(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS, false); //Optional
final CsvSchema schema = mapper.schemaFor(PojoWithLocalDate.class);
// Use this mapper and schema as you need to: get readers, writers etc.

Pojo类中不需要其他注释.

No additional annotations needed in Pojo class.
