Question

我有两个文件：people.json和[ { "name": "director", "pay": "100000"}, { "name": "programmer", "pay": "75000"}, { "name": "teacher", "pay": "50000"} ]。前者只是一系列职业：

[
    { "name": "Mary", "occupation": "programmer" },
    { "name": "Jane", "occupation": "director" },
    { "name": "John", "occupation": "teacher" }
]

后者是一些人和他们的职业：

public class Occupation {
    private final String name;
    private final int pay;


    public String getName() { ... }
    public int getPay() { ... }
}

public class Person {
    private final String name;
    private final Occupation occupation;

    public String getName() { ... }
    public String getOccupation() { ... }
}

这些是相应的类：

Person

目前我正在使用ObjectMapper.readValue(InputStream, Class) 反序列化文件。如何让Occupation类了解所有现有的{{1}}个对象？我想用职业的名字选择一个人的职业。

Answer 1

向Person.class添加一个函数

public Occupation getOccupation_()
{
  // assume you had a static occupations list...
  for (Occupation o : occupations)
    if (o.name == this.occupation)
      return o;

  return null;
}

将两个JSON文件解析为POJOS，一个引用另一个
