阳光沙滩-让学习编程变得更加简单

我的IDEA里面没有Database只可以下载Database Navigator请问可以或者如何使用这个来生成Bean类？

什么是javaBean呀java豆么？什么是javaBean呀？简单一句，封装数据。提供getter和setter。pojo我们创建了一个包，叫做pojopojo的原单词是什么呢？PlainOrdinaryJavaObject翻译过来大概是简单的java对象。知道是对象就对了，其实就是javaBean创建对应的JavaBean类JavaBean类与数据库字段对应，好在现在有逆向工程，或者我们的工具，可以直接帮助我们生成对应的java类比如说我们这里使用到的PDMan所以，我们不需要手动创建啦。后面我们去学习MyBatis逆向的时候再去学另外一种生成方式。Userimportjavax.persistence.*;importjava.io.Serializable;importjava.util.Date;importjavax.persistence.Entity;@Entity@Table(name="tb_user")publicclassUserimplementsSerializable,Cloneable{/**ID*/@IdprivateStringid;/**用户名*/privateStringuserName;/**密码*/privateStringpassword;/**头像*/privateStringavatar;/**邮箱*/privateStringemail;/**签名*/privateStringsign;/**盐值*/privateStringsalt;/**ID*/publicStringgetId(){returnthis.id;}/**ID*/publicvoidsetId(Stringid){this.id=id;}/**用户名*/publicStringgetUserName(){returnthis.userName;}/**用户名*/publicvoidsetUserName(StringuserName){this.userName=userName;}/**密码*/publicStringgetPassword(){returnthis.password;}/**密码*/publicvoidsetPassword(Stringpassword){this.password=password;}/**头像*/publicStringgetAvatar(){returnthis.avatar;}/**头像*/publicvoidsetAvatar(Stringavatar){this.avatar=avatar;}/**邮箱*/publicStringgetEmail(){returnthis.email;}/**邮箱*/publicvoidsetEmail(Stringemail){this.email=email;}/**签名*/publicStringgetSign(){returnthis.sign;}/**签名*/publicvoidsetSign(Stringsign){this.sign=sign;}/**盐值*/publicStringgetSalt(){returnthis.salt;}/**盐值*/publicvoidsetSalt(Stringsalt){this.salt=salt;}}Categorypackagegroup.rober.pdman.BlogSystem.entity;importjavax.persistence.*;importjava.io.Serializable;importjava.util.Date;importjavax.persistence.Entity;@Entity@Table(name="tb_category")publicclassCategoryimplementsSerializable,Cloneable{/**ID*/@IdprivateStringid;/**分类名称*/privateStringcategoryName;/**分类拼音*/privateStringcategoryPy;/**描述说明*/privateStringdescription;/**顺序*/privateIntegerorder;/**ID*/publicStringgetId(){returnthis.id;}/**ID*/publicvoidsetId(Stringid){this.id=id;}/**分类名称*/publicStringgetCategoryName(){returnthis.categoryName;}/**分类名称*/publicvoidsetCategoryName(StringcategoryName){this.categoryName=categoryName;}/**分类拼音*/publicStringgetCategoryPy(){returnthis.categoryPy;}/**分类拼音*/publicvoidsetCategoryPy(StringcategoryPy){this.categoryPy=categoryPy;}/**描述说明*/publicStringgetDescription(){returnthis.description;}/**描述说明*/publicvoidsetDescription(Stringdescription){this.description=description;}/**顺序*/publicIntegergetOrder(){returnthis.order;}/**顺序*/publicvoidsetOrder(Integerorder){this.order=order;}}Settingspackagegroup.rober.pdman.BlogSystem.entity;importjavax.persistence.*;importjava.io.Serializable;importjava.util.Date;importjavax.persistence.Entity;@Entity@Table(name="tb_settings")publicclassSettingsimplementsSerializable,Cloneable{/**设置项ID*/@IdprivateStringid;/**设置项key*/privateStringsettingKey;/**设置项value*/privateStringsettingValue;/**设置项ID*/publicStringgetId(){returnthis.id;}/**设置项ID*/publicvoidsetId(Stringid){this.id=id;}/**设置项key*/publicStringgetSettingKey(){returnthis.settingKey;}/**设置项key*/publicvoidsetSettingKey(StringsettingKey){this.settingKey=settingKey;}/**设置项value*/publicStringgetSettingValue(){returnthis.settingValue;}/**设置项value*/publicvoidsetSettingValue(StringsettingValue){this.settingValue=settingValue;}}Articlepackagegroup.rober.pdman.BlogSystem.entity;importjavax.persistence.*;importjava.io.Serializable;importjava.util.Date;importjavax.persistence.Entity;@Entity@Table(name="tb_article")publicclassArticleimplementsSerializable,Cloneable{/**ID*/@IdprivateStringid;/**用户ID*/privateStringuserId;/**分类ID*/privateStringcategoryId;/**内容*/privateStringcontent;/**类型;0表示富文本，1表示markdown*/privateIntegertype;/**状态;0表示已经发布，1表示草稿，2表示等待发布*/privateIntegerstatus;/**浏览量*/privateIntegerviewCount;/**发布时间*/privateDatepublishTime;/**更新时间*/privateDateupdateTime;/**ID*/publicStringgetId(){returnthis.id;}/**ID*/publicvoidsetId(Stringid){this.id=id;}/**用户ID*/publicStringgetUserId(){returnthis.userId;}/**用户ID*/publicvoidsetUserId(StringuserId){this.userId=userId;}/**分类ID*/publicStringgetCategoryId(){returnthis.categoryId;}/**分类ID*/publicvoidsetCategoryId(StringcategoryId){this.categoryId=categoryId;}/**内容*/publicStringgetContent(){returnthis.content;}/**内容*/publicvoidsetContent(Stringcontent){this.content=content;}/**类型;0表示富文本，1表示markdown*/publicIntegergetType(){returnthis.type;}/**类型;0表示富文本，1表示markdown*/publicvoidsetType(Integertype){this.type=type;}/**状态;0表示已经发布，1表示草稿，2表示等待发布*/publicIntegergetStatus(){returnthis.status;}/**状态;0表示已经发布，1表示草稿，2表示等待发布*/publicvoidsetStatus(Integerstatus){this.status=status;}/**浏览量*/publicIntegergetViewCount(){returnthis.viewCount;}/**浏览量*/publicvoidsetViewCount(IntegerviewCount){this.viewCount=viewCount;}/**发布时间*/publicDategetPublishTime(){returnthis.publishTime;}/**发布时间*/publicvoidsetPublishTime(DatepublishTime){this.publishTime=publishTime;}/**更新时间*/publicDategetUpdateTime(){returnthis.updateTime;}/**更新时间*/publicvoidsetUpdateTime(DateupdateTime){this.updateTime=updateTime;}}Looperpackagegroup.rober.pdman.BlogSystem.entity;importjavax.persistence.*;importjava.io.Serializable;importjava.util.Date
