如果在读写 JSON 时，我们想忽略某些字段，我们可以使用下面的注解。
@JsonIgnore
package shangbo.jackson.demo7;
import java.util.Date;
import org.apache.commons.lang3.builder.ToStringBuilder;
import com.fasterxml.jackson.annotation.JsonIgnore;
public class Person {
private String firstname;
private String lastname;
@JsonIgnore
private Date brithday;
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;
}
public Date getBrithday() {
return brithday;
}
public void setBrithday(Date brithday) {
this.brithday = brithday;
}
}
@JsonIgnoreProperties
package shangbo.jackson.demo8;
import java.util.Date;
import org.apache.commons.lang3.builder.ToStringBuilder;
import com.fasterxml.jackson.annotation.JsonIgnoreProperties;
@JsonIgnoreProperties({"brithday"})
public class Person {
private String firstname;
private String lastname;
private Date brithday;
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;
}
public Date getBrithday() {
return brithday;
}
public void setBrithday(Date brithday) {
this.brithday = brithday;
}
}
@JsonIgnoreType
package shangbo.jackson.demo9;
import org.apache.commons.lang3.builder.ToStringBuilder;
import com.fasterxml.jackson.annotation.JsonIgnoreType;
@JsonIgnoreType
public class Address {
private String state;
private String city;
private String streat;
public String toString() {
