# Teacher .java 在src上右建，新建一個entity包。 在entity右鍵，新建一個Teacher.java文件。 鍵入以下內容： ``` package entity; public class Teacher { private int id; // 主鍵 private String name; // 姓名 private String username; // 用戶名 private String email; // 郵箱 private Boolean sex = false; // 性別 0：男；1：女 private String password; // 密碼 } ``` ## 生成get/set ``` package entity; public class Teacher { private int id; // 主鍵 private String name; // 姓名 private String username; // 用戶名 private String email; // 郵箱 private Boolean sex = false; // 性別 0：男；1：女 private String password; // 密碼 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 getUsername() { return username; } public void setUsername(String username) { this.username = username; } public String getEmail() { return email; } public void setEmail(String email) { this.email = email; } public Boolean getSex() { return sex; } public void setSex(Boolean sex) { this.sex = sex; } public String getPassword() { return password; } public void setPassword(String password) { this.password = password; } } ``` ## 生成構造函數 生成帶有空參數的構造函數及帶有參數的構造函數 ``` package entity; public class Teacher { private int id; // 主鍵 private String name; // 姓名 private String username; // 用戶名 private String email; // 郵箱 private Boolean sex = false; // 性別 0：男；1：女 private String password; // 密碼 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 getUsername() { return username; } public void setUsername(String username) { this.username = username; } public String getEmail() { return email; } public void setEmail(String email) { this.email = email; } public Boolean getSex() { return sex; } public void setSex(Boolean sex) { this.sex = sex; } public String getPassword() { return password; } public void setPassword(String password) { this.password = password; } public Teacher() { } public Teacher(int id, String name, String username, String email, Boolean sex, String password) { // super(); this.id = id; this.name = name; this.username = username; this.email = email; this.sex = sex; this.password = password; } } ``` ## 生成toString\(\) 為了以后我們便于在控制臺打印實體信息，增加toString很有必要。 ``` package entity; public class Teacher { private int id; // 主鍵 private String name; // 姓名 private String username; // 用戶名 private String email; // 郵箱 private Boolean sex = false; // 性別 0：男；1：女 private String password; // 密碼 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 getUsername() { return username; } public void setUsername(String username) { this.username = username; } public String getEmail() { return email; } public void setEmail(String email) { this.email = email; } public Boolean getSex() { return sex; } public void setSex(Boolean sex) { this.sex = sex; } public String getPassword() { return password; } public void setPassword(String password) { this.password = password; } public Teacher() { } public Teacher(int id, String name, String username, String email, Boolean sex, String password) { // super(); this.id = id; this.name = name; this.username = username; this.email = email; this.sex = sex; this.password = password; } public String toString() { return "Teacher [id=" + id + ", name=" + name + ", username=" + username + ", email=" + email + ", sex=" + sex + ", password=" + password + "]"; } } ``` 在eclipse中，我們可以通過生成set\get函數，生成帶有參數的構造函數，生成toString函數，來自動生成上述大部分代碼。
