篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了无法使用camel编组格式化LocalDate对象相关的知识,希望对你有一定的参考价值。

我正在使用驼峰路由将用户对象保存到文件,同时保存我正在使用camel marshaling选项将用户对象转换为json。虽然编组它是以下列格式保存日期对象

"birthDate":{"year":2018,"month":"FEBRUARY","era":"CE","dayOfMonth":20,"dayOfWeek":"TUESDAY","dayOfYear":51,"leapYear":false,"monthValue":2,"chronology":{"id":"ISO","calendarType":"iso8601"}}

想要的格式是

  "birthDate":"20-feb-2018"

这是我的POJO

public class User implements Serializable{

    private String id;

    private String fName;

    private String lName;

    private String email;

    private Integer  pinCode;

    @JsonFormat(pattern="dd-MMM-yyyy")
    private LocalDate birthDate;

    private Boolean isActive;
}

路由网址是

from("direct:saveUserJson").marshal().json(JsonLibrary.Jackson,User.class).to("file:"+filePath+"?fileName=${exchangeProperty.fileName}");

和pom.xml我在使用版本2.20.1的camel-jackson-starter和camel-spring-boot-starter

答案

不确定,但是当您将形状String添加到注释时,它可能会起作用:

@JsonFormat(shape = JsonFormat.Shape.STRING, pattern = "dd-MMM-yyyy")
