今天的任务依旧是完成多条件的查询

困难时dao层编写、

package com.example.shiyan.entity;

public class Student {
private String id;
private String password;
private String name;
private String age;
public Student(){

}

public Student(String id, String password, String name, String age){
this.id=id;
this.age=age;
this.name=name;
this.password=password;
}

public Student(String id) {
this.id=id;
}

public String getId() {
return id;
}

public void setId(String id) {
this.id = id;
}

public String getPassword() {
return password;
}

public void setPassword(String password) {
this.password = password;
}

public String getName() {
return name;
}

public void setName(String name) {
this.name = name;
}

public String getAge() {
return age;
}

public void setAge(String age) {
this.age = age;
}
}
