二、实体类构建
1、博客实体类
package net.zjs.lrm.po;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.persistence.Table;
import java.util.Date;
/**

@Entity(name = "t_blog")
@Table
public class Blog {
@Id
@GeneratedValue
private Long id; //主键
private String title; //标题
private String content; //内容
private String firstPicture; //首图
private String flag; //标记
private Integer views; //浏览次数
private boolean appreciation; //赞赏开启
private boolean shareStatement; //版权开启
private boolean commentabled; //评论开启
private boolean published; //发布
private boolean recommend; //推荐
@Temporal(TemporalType.TIMESTAMP) //设置时间生成的格式
private Date createTime; //创建时间
@Temporal(TemporalType.TIMESTAMP) //设置时间生成的格式
private Date updateTime; //更新时间
public Blog() {
}
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public String getTitle() {
return title;
}
public void setTitle(String title) {
this.title = title;
}
public String getContent() {
return content;
}
public void setContent(String content) {
this.content = content;
}
public String getFirstPicture() {
return firstPicture;
}
public void setFirstPicture(String firstPicture) {
this.firstPicture = firstPicture;
}
public String getFlag() {
return flag;
}
public void setFlag(String flag) {
this.flag = flag;
}
public Integer getViews() {
return views;
}
public void setViews(Integer views) {
this.views = views;
}
public boolean isAppreciation() {
return appreciation;
}
public void setAppreciation(boolean appreciation) {
this.appreciation = appreciation;
}
public boolean isShareStatement() {
return shareStatement;
}
public void setShareStatement(boolean shareStatement) {
this.shareStatement = shareStatement;
}
public boolean isCommentabled() {
return commentabled;
}
public void setCommentabled(boolean commentabled) {
this.commentabled = commentabled;
}
public boolean isPublished() {
return published;
}
public void setPublished(boolean published) {
this.published = published;
}
public boolean isRecommend() {
return recommend;
}
public void setRecommend(boolean recommend) {
this.recommend = recommend;
}
public Date getCreateTime() {
return createTime;
}
public void setCreateTime(Date createTime) {
this.createTime = createTime;
}
public Date getUpdateTime() {
return updateTime;
}
public void setUpdateTime(Date updateTime) {
this.updateTime = updateTime;
}
@Override
public String toString() {
return "Blog{" +
"id=" + id +
", title='" + title + '\\'' +
", content='" + content + '\\'' +
", firstPicture='" + firstPicture + '\\'' +
", flag='" + flag + '\\'' +
", views=" + views +
", appreciation=" + appreciation +
", shareStatement=" + shareStatement +
", commentabled=" + commentabled +
", published=" + published +
", recommend=" + recommend +
", createTime=" + createTime +
", updateTime=" + updateTime +
'}';
}
}
2、博客分类实体类
package net.zjs.lrm.po;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.persistence.Table;
/**
* 功能：博客分类
* 作者：zjs
* 日期：2021-06-11
*/
@Entity(name = "t_type")
@Table
public class Type {
@Id
@GeneratedValue
private Long id;
private String name;
public Type() {
}
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
@Override
public String toString() {
return "Type{" +
"id=" + id +
", name='" + name + '\\'' +
'}';
}
}
3、博客标签实体类
package net.zjs.lrm.po;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.persistence.Table;
/**
* 功能：博客标签
* 作者：zjs
* 日期：2021-06-11
*/
@Entity(name = "t_tag")
@Table
public class Tag {
@Id
@GeneratedValue
private Long id;
private String name;
public Tag() {
}
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
@Override
public String toString() {
return "Tag{" +
"id=" + id +
", name='" + name + '\\'' +
'}';
}
}
4、博客评论
package net.zjs.lrm.po;
import javax.persistence.*;
import java.security.PrivateKey;
import java.util.Date;
/**
* 功能：博客评论实体类
* 作者：zjs
* 日期：2021-06-11
*/
@Entity(name = "t_comment")
@Table
public class Comment {
@Id
@GeneratedValue
private Long id;
private String nickname;//昵称
private String email; //邮箱
private String content;//评论的内容
private String avatar;//头像
@Temporal(TemporalType.TIMESTAMP) //设置时间生成的格式
private Date createTime;//创建时间
public Comment() {
}
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public String getNickname() {
return nickname;
}
public void setNickname(String nickname) {
this.nickname = nickname;
}
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
public String getContent() {
return content;
}
public void setContent(String content) {
this.content = content;
}
public String getAvatar() {
return avatar;
}
public void setAvatar(String avatar) {
this.avatar = avatar;
}
public Date getCreateTime() {
return createTime;
}
public void setCreateTime(Date createTime) {
this.createTime = createTime;
}
@Override
public String toString() {
return "Comment{" +
"id=" + id +
", nickname='" + nickname + '\\'' +
", email='" + email + '\\'' +
", content='" + content + '\\'' +
", avatar='" + avatar + '\\'' +
", createTime=" + createTime +
'}';
}
}
5、用户类
package net.zjs.lrm.po;
import javax.persistence.*;
import java.util.Date;
/**
* 功能：用户实体类
* 作者：zjs
* 日期：2021-06-11
*/
@Entity(name = "t_user")
@Table
public class User {
@Id
@GeneratedValue
private Long id;
private String nickname;//昵称
private String username;//用户名
private String password;//密码
private String email;//邮箱
private String avatar;//头像
private Integer type;//类型
@Temporal(TemporalType.TIMESTAMP) //设置时间生成的格式
private Date createTime;//创建时间
@Temporal(TemporalType.TIMESTAMP) //设置时间生成的格式
private Date updateTime;//更新时间
public User() {
}
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public String getNickname() {
return nickname;
}
public void setNickname(String nickname) {
this.nickname = nickname;
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
public String getAvatar() {
return avatar;
}
public void setAvatar(String avatar) {
this.avatar = avatar;
}
public Integer getType() {
return type;
}
public void setType(Integer type) {
this.type = type;
}
public Date getCreateTime() {
return createTime;
}
public void setCreateTime(Date createTime) {
this.createTime = createTime;
}
public Date getUpdateTime() {
return updateTime;
}
public void setUpdateTime(Date updateTime) {
this.updateTime = updateTime;
}
@Override
public String toString() {
return "User{" +
"id=" + id +
", nickname='" + nickname + '\\'' +
", username='" + username + '\\'' +
", password='" + password + '\\'' +
", email='" + email + '\\'' +
", avatar='" + avatar + '\\'' +
", type=" + type +
", createTime=" + createTime +
", updateTime=" + updateTime +
'}';
}
}
6、处理实体类之间的关系
- Blog类与Type类建立关系
- Blog类与Tag类建立关系
- Blog类与User类建立关系
- Blog类与Comment类建立关系
7、处理评论类自关联的关系
- 注意：每次添加完关系之后都要setter and getter
8、运行服务器，查看数据库
