<!-- 使用json-lib --> <dependency> <groupId>net.sf.json-lib</groupId> <artifactId>json-lib</artifactId> <version>2.4</version> <classifier>jdk15</classifier> </dependency>
代码:
// 对象到文本 Emp emp=new Emp(); emp.setId(1001); emp.setName("苗婉秋"); emp.setSalary(1000); JSONObject jsonObject = JSONObject.fromObject(emp); System.out.println("emp对象的json文本=" + jsonObject); // 文本到对象 String jsonStr = "{"id":1001,"name":"苗婉秋","salary":1000}"; JSONObject jsonObject1 = JSONObject.fromObject(jsonStr); Emp emp2 = (Emp) JSONObject.toBean(jsonObject1,Emp.class); System.out.println(emp2);
输出:
emp对象的json文本={"id":1001,"name":"苗婉秋","salary":1000}
emp:1001,苗婉秋,1000
使用到的Emp对象
package jsonSample; public class Emp { private long id; private String name; private int salary; public String toString() { return String.format("emp:%d,%s,%d",id,name,salary); } public long getId() { return id; } public void setId(long id) { this.id = id; } public String getName() { return name; } public void setName(String name) { this.name = name; } public int getSalary() { return salary; } public void setSalary(int salary) { this.salary = salary; } }
