fastjson解析任意json到bean
解析案例的代码
package com.base.config; import java.util.List; import com.alibaba.fastjson.JSONArray;
import com.alibaba.fastjson.JSONObject; public class JsonParse { public static void main(String[] args) { String arrJson = "[{\"id\":1,\"mobile\":15809619172},{\"id\":2,\"mobile\":14588827746}]";
List<Student> stus = JSONArray.parseArray(arrJson, Student.class); System.out.println("array json的解析结果:"); for (Student stu : stus) {
System.out.println(stu);
} String beanJson = "{\"id\":1,\"mobile\":15809619172}";
Student stu = JSONObject.parseObject(beanJson, Student.class);
System.out.println("beanjson的解析结果:");
System.out.println(stu); } }
Student的代码
package com.base.config; public class Student {
private int id;
private String mobile; public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getMobile() {
return mobile;
}
public void setMobile(String mobile) {
this.mobile = mobile;
} @Override
public String toString() {
return "Student [id=" + id + ", mobile=" + mobile + "]";
} }
程序运行结果
array json的解析结果:
Student [id=1, mobile=15809619172]
Student [id=2, mobile=14588827746]
beanjson的解析结果:
Student [id=1, mobile=15809619172]
这样解析效率很高,而且代码非常简单。比json-lib库要简化非常多。所以强烈推荐使用fastjson.
