我有2个API响应，并将它们转换为Json Array。当我将2个json转换为键值对映射时，值的顺序不同并且无法在2个API响应之间进行比较。
API 1的JsonArray：
[
{
"employeeSalutation": null,
"EmployeeName": "Example",
"EmployeeCode": "SAA",
"Zip": 12345,
"DepartmentName": "Social science",
"EmployeeAddress": "123 st",
"StateCode": 9,
"updatedDate": "2018-01-22T03:48:43.59",
"EmployeeId": 1257
}
]
API 2的Json数组：
[
{
"Emp_Name": "Example",
"emp_Sal": null,
"Dept_Name": "Social science",
"Emp_addr": "123 st",
"Zip": "12345",
"Stat_cd": 9,
"Emp_id": 1257,
"upd_d": "2018-01-22 03:48:43.59",
"Emp_Code": "SAA"
}
]
[我将2个Json数组转换为键值对的映射，其中EmployeeId作为数组1的键，而Emp_id作为数组2的键。当我比较2个映射时，映射值的顺序不同，并且会失败。
如何比较2个API，以确保2个API中的每个元素的值都匹配。
由于您使用Java进行此操作，因此建议您将此值映射到Java对象中。这样，您将非常容易比较值。您可以使用像Gson这样的库，但是在这里，我将向您展示如何在没有库的情况下做到这一点。
创建一个易于使用的API响应类：
public class Employee {
private String employeeSalutation; //i am not sure what type should this variable be
private String employeeName;
private String employeeCode;
private int zip;
private String departmentName;
private String employeeAddress;
private int stateCode;
private String updatedDate;
private int employeeId;
//this is where your parser can be used
public Employee(String employeeSalutation, String employeeName, String employeeCode,
int zip, String departmentName, String employeeAddress, int stateCode,String updatedDate, int employeeId){
this.employeeSalutation = employeeSalutation;
this.employeeName = employeeName;
this.employeeCode = employeeCode;
this.zip = zip;
this.departmentName = departmentName;
this.employeeAddress = employeeAddress;
this.stateCode = stateCode;
this.updatedDate = updatedDate;
this.employeeId = employeeId;
}
//getters, setters
}
现在您可以拥有一个用于将该数组转换为Java对象的类，将其称为EmployeeConverter：
public class EmployeeConverter {
public Employee convertApi1Employee(String json){
//since you didn't clarify how are you accessing your Json values, i will now use pseudo-code to finish my answer.
//using variable.value pseudo-code to access json property value
return new Employee(employeeSalutation.value, EmployeeName.value, EmployeeCode.value, Zip.value, DepartmentName.value, EmployeeAddress.value, EmployeeAddress.value, StateCode.value, updatedDate.value, EmployeeId.value);
}
}
您应该创建方法convertApi2Employee（），该方法具有与convertApi1Employee（）方法相同的功能，但是将使用不同的JSON对象。
我希望这会有所帮助。
首先，您需要创建一个模型来表示这两个JSON有效负载。除了Zip键的键名和值外，它们几乎相似，其中在第一个有效负载中它是第二个数字原语-String原语。日期也具有不同的格式，因此您需要通过实现自定义日期反序列化器来处理它们。
绝对应该使用Jackson或Gson库，该库允许将JSON反序列化为POJO模型，提供自定义日期反序列化器，以及许多其他功能。
