我很難想出一種解析這種 JSON 的方法。在我的應(yīng)用程序中獲得此響應(yīng)后，我需要能夠分別訪問數(shù)據(jù)和消息。{ "data": [ { "email": "eskaferas@gmail.com", "firstName": "Seras", "lastName": "Meras" }, { "email": "Soras@gmail.com", "firstName": "Oras", "lastName": "Moras" }, { "email": "bzbzb@gmail.com", "firstName": "hello", "lastName": "bye" }, { "email": "lrc@gmail.com", "firstName": "Seras", "lastName": "Meras" } ], "message": "Success"}任何人都可以建議一種專門用于 Spring Boot 的方法嗎？或者是 Spring boot 中用來(lái)解析這種 JSON 類型的常用方法。謝謝你。編輯我的主要問題是 Spring Boot 可以使用什么工具，如果我使用 Jackson，我的 POJO 類會(huì)是什么樣子。會(huì)是這樣嗎？：public class testPojo { Users[] users; String message;}

Pojo 類將如下所示：
public class TestPojo{
private Users[] data;
private String message;
public Users[] getData() {
return data;
}
public void setData(Users[] data) {
this.data = data;
}
public String getMessage() {
return message;
}
public void setMessage(String message) {
this.message = message;
}
}
class Users {
private String email;
private String firstName;
private String lastName;
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
public String getFirstName() {
return firstName;
}
public void setFirstName(String firstName) {
this.firstName = firstName;
}
public String getLastName() {
return lastName;
}
public void setLastName(String lastName) {
this.lastName = lastName;
}
}
在控制器的方法參數(shù)中使用 @RequestBody。
@RestController
class AbcController{
PostMapping("/api")
public String create(@RequestBody TestPojo test){
// you can acess your json in test object
return "done"
}
}
