实现步骤

步骤一：创建实体类

步骤二： 创建学校实体类所对应的实体表

可使用快捷方式Getter and Setter 和 to String()直接生成后段代码 下面展示一些 详细代码。

package net.lyq.student.bean; import java.util.Date; public class College { private int id; //学校id private String name; //学校名称 private String president; //校长 private Date startTime; //建校时间 private String telephone; //联系电话 private String email; //邮箱 private String address; //通信地址 private String profile; //学校简介 //使用Getter and Setter自动生成 public int getId() { return id; } public void setId(int id) { this.id = id; } public String getName() { return name; } public void setName(String name) { this.name = name; } public String getPresident() { return president; } public void setPresident(String president) { this.president = president; } public Date getStartTime() { return startTime; } public void setStartTime(Date startTime) { this.startTime = startTime; } public String getTelephone() { return telephone; } public void setTelephone(String telephone) { this.telephone = telephone; } public String getEmail() { return email; } public void setEmail(String email) { this.email = email; } public String getAddress() { return address; } public void setAddress(String address) { this.address = address; } public String getProfile() { return profile; } public void setProfile(String profile) { this.profile = profile; } //使用to String()自动生成 @Override public String toString() { return "College{" + "id=" + id + ", name='" + name + '\'' + ", president='" + president + '\'' + ", startTime=" + startTime + ", telephone='" + telephone + '\'' + ", email='" + email + '\'' + ", address='" + address + '\'' + ", profile='" + profile + '\'' + '}'; } }

步骤三：创建状态类对应状态表

下面展示一些 代码详情。

package net.lyq.student.bean; public class Status { private int id; //状态标识符 private String college; //校名 private String version; //软件版本 private String aythor; //软件作者 private String telephone;//联系电话 private String address; // 通信地址 private String email; //电子邮箱 //使用Getter and Setter自动生成 public int getId() { return id; } public void setId(int id) { this.id = id; } public String getCollege() { return college; } public void setCollege(String college) { this.college = college; } public String getVersion() { return version; } public void setVersion(String version) { this.version = version; } public String getAythor() { return aythor; } public void setAythor(String aythor) { this.aythor = aythor; } public String getTelephone() { return telephone; } public void setTelephone(String telephone) { this.telephone = telephone; } public String getAddress() { return address; } public void setAddress(String address) { this.address = address; } public String getEmail() { return email; } public void setEmail(String email) { this.email = email; } //使用to String()自动生成 @Override public String toString() { return "Status{" + "id=" + id + ", college='" + college + '\'' + ", version='" + version + '\'' + ", aythor='" + aythor + '\'' + ", telephone='" + telephone + '\'' + ", address='" + address + '\'' + ", email='" + email + '\'' + '}'; } }

步骤四：创建学生实体类对应学生表

下面展示一些 内联代码片。

package net.lyq.student.bean; public class Student { private String id; //学号 private String name; //姓名 private String sex; //性别 private int age; //年龄 private String department; //系部 private String clazz; //班级 private String telephone; //联系电话 //使用Getter and Setter自动生成 public String getId() { return id; } public void setId(String id) { this.id = id; } public String getName() { return name; } public void setName(String name) { this.name = name; } public String getSex() { return sex; } public void setSex(String sex) { this.sex = sex; } public int getAge() { return age; } public void setAge(int age) { this.age = age; } public String getDepartment() { return department; } public void setDepartment(String department) { this.department = department; } public String getClazz() { return clazz; } public void setClazz(String clazz) { this.clazz = clazz; } public String getTelephone() { return telephone; } public void setTelephone(String telephone) { this.telephone = telephone; } //使用to String()自动生成 @Override public String toString() { return "Student{" + "id='" + id + '\'' + ", name='" + name + '\'' + ", sex='" + sex + '\'' + ", age=" + age + ", department='" + department + '\'' + ", clazz='" + clazz + '\'' + ", telephone='" + telephone + '\'' + '}'; } }

步骤五：创建用户实体类对应的用户表

下面展示一些 内联代码片。

package net.lyq.student.bean; import java.util.Date; public class User { private int id; //用户标识符 private String username; //用户名 private String password; //密码 private String telephone; //联系电话 private Date registerTime; //注册时间 //使用Getter and Setter自动生成 public int getId() { return id; } public void setId(int id) { this.id = id; } 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 getTelephone() { return telephone; } public void setTelephone(String telephone) { this.telephone = telephone; } public Date getRegisterTime() { return registerTime; } public void setRegisterTime(Date registerTime) { this.registerTime = registerTime; } //使用to String()自动生成 @Override public String toString() { return "User{" + "id=" + id + ", username='" + username + '\'' + ", password='" + password + '\'' + ", telephone='" + telephone + '\'' + ", registerTime=" + registerTime + '}'; } }
