问题描述

jackson json 使用问题

有Department类
public class Department {
private Long id;
private String name;
private Department parDepartment;//上级部门

    //method set、get   .......

}

有如下dept和dept1 2个对象，dept是dept1的上级部门
Department dept = new Department();
dept.setId(1L);
dept.setName(""宜通世纪"");

Department dept1 = new Department();dept1.setId(2L);dept1.setName(""终端解决方案部"");dept1.setParDepartment(dept);

如何使用jackson的注解设置Department类，使得dept1转成json对象时是一下格式：
{""id"":2name"":""终端解决方案部""pId"":1}
