gson parse json to object array 2018-10-19 05:23
In this page I will show you how to use gson parse json string to object array. Add gson dependency in pom.xml file.
<dependency>
<groupId>com.google.code.gson</groupId>
<artifactId>gson</artifactId>
<version>2.8.2</version>
</dependency>
The User entity is here
public class User {
private String name;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
@Override
public String toString() {
return "User{" +
"name='" + name + '\'' +
'}';
}
}
The client is here
public class GsonClient {
public static void main(String[] args) {
String usersJson = "[ { \"name\": \"henry\" }, { \"name\": \"justin\" } ]";
Gson gson = new Gson();
User[] users = gson.fromJson(usersJson, User[].class);
for (User user : users) {
System.out.println(user);
}
}
}
Run main method and get the output.
User{name='henry'}
User{name='justin'}
