我想知道是否有一个网页/软件可以将Json Feed对象“转换”为具有属性的
Java对象.
例如 ：
{
'firstName': 'John','lastName': 'Smith','address': {
'streetAddress': '21 2nd Street','city': 'New York'
}
}
会成为：
class Person {
private String firstName;
private String lastName;
private Address address;
public String getFirstName() { return firstName; }
public String getLastName() { return lastName; }
public Address getAddress() { return address; }
public void setFirstName(String firstName) { this.firstName = firstName; }
public void setLastName(String lastName) { this.lastName = lastName; }
public void setAddress(Address address) { this.address = address; }
public String toString() {
return String.format("firstName: %s,lastName: %s,address: [%s]",firstName,lastName,address);
}
}
class Address {
private String streetAddress;
private String city;
public String getStreetAddress() { return streetAddress; }
public String getCity() { return city; }
public void setStreetAddress(String streetAddress) { this.streetAddress = streetAddress; }
public void setCity(String city) { this.city = city; }
public String toString() {
return String.format("streetAddress: %s,city: %s",streetAddress,city);
}
}
我不是因为我很懒,但是我要解析的JSON有很多属性.
解决方法
我已成功使用
json-lib进行json序列化和反序列化.你的例子看起来像这样：
String json = "{'firstName': 'John','address': {'streetAddress': '21 2nd Street','city': 'New York'}}";
JSONObject jsonObject = JSONObject.fromObject(json);
Person bean = (Person) JSONObject.toBean(jsonObject,Person.class);
System.out.println(bean);
并打印
firstName: John,lastName: Smith,address: [streetAddress: 21 2nd Street,city: New York]
如果你需要自定义它有很多扩展钩子.在我的应用程序中,我添加了对将Locale序列化为字符串“sv_SE”而不是对象的支持.并将相同的字符串反序列化为Locale对象.
