如果 JSON 和對象字段名不匹配，我們可以使用注解 @JsonGetter 和 @JsonSetter，在不改變字段名的情況下，改變json的屬性名

package shangbo.jackson.demo11;import java.util.Date;import org.apache.commons.lang3.builder.ToStringBuilder;import com.fasterxml.jackson.annotation.JsonGetter; import com.fasterxml.jackson.annotation.JsonSetter;public class Person {private String firstname;private String lastname;private Date birthday;public String toString() {return ToStringBuilder.reflectionToString(this);}public String getFirstname() {return firstname;}public void setFirstname(String firstname) {this.firstname = firstname;}public String getLastname() {return lastname;}public void setLastname(String lastname) {this.lastname = lastname;}@JsonGetter("age")public Date getBirthday() {return birthday;}@JsonSetter("age")public void setBirthday(Date birthday) {this.birthday = birthday;} } package shangbo.jackson.demo11;import java.util.Date;import com.fasterxml.jackson.databind.ObjectMapper;public class App {public static void main(String[] args) throws Exception {// 實例化 ObjectMapper 對象ObjectMapper objectMapper = new ObjectMapper();// 將對象轉成 jsonString json = objectMapper.writeValueAsString(newPerson());System.out.println(json);// 將 json 轉成對象Person shangbo = objectMapper.readValue(json, Person.class);System.out.println(shangbo);}private static Person newPerson() {Person shangbo = new Person();shangbo.setFirstname("Bo");shangbo.setLastname("Shang");shangbo.setBirthday(new Date());return shangbo;} }
