@jsonignore的作用

作用是json序列化时将java bean中的一些属性忽略掉,序列化和反序列化都受影响。

如下：

package com.hzboy.orm;import java.util.List;import javax.persistence.CascadeType;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.FetchType;
import javax.persistence.JoinColumn;
import javax.persistence.JoinTable;
import javax.persistence.ManyToMany;
import javax.persistence.ManyToOne;
import javax.persistence.Table;
import javax.persistence.Transient;import org.codehaus.jackson.annotate.JsonIgnore;
import org.codehaus.jackson.annotate.JsonIgnoreProperties;
import org.codehaus.jackson.annotate.JsonManagedReference;/*** 系统用户实体类* @author tinner**/
@Entity(name = "com.hzboy.orm.User")
