package org.springblade.modules.property;

import com.fasterxml.jackson.databind.ObjectMapper;
import lombok.Data;

@Data
class TestPo{
    private Integer myint;
}

public class JacksonTest {
    public static void main(String[] args){
        TestPo testPo = new TestPo();
        testPo.setMyint(1);
        ObjectMapper mapper = new ObjectMapper();
        try {

            String json = mapper.writeValueAsString(testPo);
            System.out.println(json);

            TestPo testPo2 = mapper.readValue(json,TestPo.class);
            System.out.println(testPo2);
        }catch(Exception e){
            e.printStackTrace();
