使用Java中的flexjson库漂亮地打印JSON？
该Flexjson 是一个轻量级的 Java库，用于序列化和反序列化的Javabean，映射，数组，并集合 在一个JSON 格式。一个JSONSerializer 是执行的Java序列化对象到JSON，默认情况下执行一个主类浅 序列化。我们可以使用JSONSerializer 类的prettyPrint（booleanprettyPrint）方法漂亮地打印JSON。
语法
public JSONSerializer prettyPrint(boolean prettyPrint)
在下面的程序中，使用flexjson库漂亮地打印JSON
示例
import flexjson.*;
public class PrettyPrintJSONTest {
public static void main(String[] args) {
JSONSerializer serializer = new JSONSerializer().prettyPrint(true); // pretty print
Employee emp = new Employee("Vamsi", "105", "Python Developer", "Python", "Pune");
String jsonStr = serializer.serialize(emp);
System.out.println(jsonStr);
}
}
// Employee classclass Employee {
private String name, id, designation, technology, location;
public Employee(String name, String id, String designation, String technology, String location) {
super();
this.name = name;
this.id = id;
this.designation = designation;
this.technology = technology;
this.location = location;
}
public String getName() {
return name;
}
public String getId() {
return id;
}
public String getDesignation() {
return designation;
}
public String getTechnology() {
return technology;
}
public String getLocation() {
return location;
}
}输出结果
{
"class": "Employee",
"designation": "Python Developer",
"id": "105",
"location": "Pune",
"name": "Vamsi",
"technology": "Python"
}
