本篇內(nèi)容主要講解“idea怎么從數(shù)據(jù)庫快速生成Spring Data JPA實體類”,感興趣的朋友不妨來看看。本文介紹的方法操作簡單快捷,實用性強。下面就讓小編來帶大家學(xué)習(xí)“idea怎么從數(shù)據(jù)庫快速生成Spring Data JPA實體類”吧!
File—>Project Structure—>model—> + —>JPA
1.數(shù)據(jù)源,即鏈接數(shù)據(jù)庫的信息,按要求填寫數(shù)據(jù)庫信息即可
2.生成實體類的位置.
3.實體類名稱前綴.這里我什么都沒寫.
4.實體類名稱后綴. 這里我寫Entity. 比如數(shù)據(jù)庫表名為 user,那么生成實體類為 UserEntity
5.選擇哪些表的哪些字段生成實體類.這里我全選.
6.生成的實體類自動添加 JPA注解.
如:
package com.itguang.weixinsell.entity; import javax.persistence.Basic; import javax.persistence.Column; import javax.persistence.Entity; import javax.persistence.Id; import javax.persistence.Table; import java.sql.Timestamp; /** * @author itguang * @create @Entity @Table(name = "product_category", schema = "sell", catalog = "") public class ProductCategoryEntity private int categoryId; private String categoryName; private int categoryType; private Timestamp createTime; private Timestamp updateTime; @Id @Column(name = "category_id") public int getCategoryId() { return categoryId; } public void setCategoryId(int categoryId) { this.categoryId = categoryId; } @Basic @Column(name = "category_name") public String getCategoryName() { return categoryName; } public void setCategoryName(String categoryName) { this.categoryName = categoryName; } @Basic @Column(name = "category_type") public int getCategoryType() { return categoryType; } public void setCategoryType(int categoryType) { this.categoryType = categoryType; } @Basic @Column(name = "create_time") public Timestamp getCreateTime() { return createTime; } public void setCreateTime(Timestamp createTime) { this.createTime = createTime; } @Basic @Column(name = "update_time") public Timestamp getUpdateTime() { return updateTime; } public void setUpdateTime(Timestamp updateTime) { this.updateTime = updateTime; } @Override public boolean equals(Object o) { if (this == o) return true; if (o == null || getClass() != o.getClass()) return false; ProductCategoryEntity that = (ProductCategoryEntity) o; if (categoryId != that.categoryId) return false; if (categoryType != that.categoryType) return false; if (categoryName != null ? !categoryName.equals(that.categoryName) : that.categoryName != null) return false; if (createTime != null ? !createTime.equals(that.createTime) : that.createTime != null) return false; if (updateTime != null ? !updateTime.equals(that.updateTime) : that.updateTime != null) return false; return true; } @Override public int hashCode() { int result = categoryId; result = 31 * result + (categoryName != null ? categoryName.hashCode() : 0); result = 31 * result + categoryType; result = 31 * result + (createTime != null ? createTime.hashCode() : 0); result = 31 * result + (updateTime != null ? updateTime.hashCode() : 0); return
到此,相信大家對“idea怎么從數(shù)據(jù)庫快速生成Spring Data JPA實體類”有了更深的了解,不妨來實際操作一番吧!這里是億速云網(wǎng)站,更多相關(guān)內(nèi)容可以進入相關(guān)頻道進行查詢,關(guān)注我們,繼續(xù)學(xué)習(xí)!
