我需要用Jackson库解析相对复杂的JSON。你们可以建议我应该使用什么Java类结构以及Jackson用来解析以下JSON对象的方法。
就像这样:
{
"firstField": "Something One",
"secondField": "Something Two",
"thirdField": [
{
"thirdField_one": "Something Four",
"thirdField_two": "Something Five"
},
{
"thirdField_one": "Something Six",
"thirdField_two": "Something Seven"
}
],
"fifthField": [
{
"fifthField_one": "Something… ",
"fifthField_two": "Something...",
"fifthField_three": 12345
},
{
"fifthField_one": "Something",
"fifthField_two": "Something",
"fifthField_three": 12345
}
]
}
答案 0 :(得分:1)
我对Gson更精通,但我认为这应该有效。
请参阅下面的StaxMan注释:
Jackson不会自动检测私有字段(可以使用@JsonAutoDetect或全局配置)。所以字段应该是私有的,用@JsonProperty注释,或者具有匹配的公共getter。
public class MyClass {
private String firstField, secondField;
private ThirdField thirdField;
private FifthField fifthField;
public static class ThirdField {
private List<ThirdFieldItem> thirdField;
}
public static class ThirdFieldItem {
private String thirdField_one, thirdField_two;
}
public static class FifthField {
private List<FifthFieldItem> fifthField;
}
public static class FifthField {
private String fifthField_one, fifthField_two;
private int fifthField_three;
}
}
