寝室类如下：
import java.util.List;
import java.util.Objects;
public class Bedroom {
private String place;
private String manager;
private Integer bedCount;
private Integer tableCount;
private ListPerson persons;
private char sexFlag;//男：1 女：2
public String getPlace() {
return place;
}
public void setPlace(String place) {
this.place = place;
}
public String getManager() {
return manager;
}
public void setManager(String manager) {
this.manager = manager;
}
public Integer getBedCount() {
return bedCount;
}
public void setBedCount(Integer bedCount) {
this.bedCount = bedCount;
}
public Integer getTableCount() {
return tableCount;
}
public void setTableCount(Integer tableCount) {
this.tableCount = tableCount;
}
public ListPerson getPersons() {
return persons;
}
public void setPersons(ListPerson persons) {
this.persons = persons;
}
public char getSexFlag() {
return sexFlag;
}
public void setSexFlag(char sexFlag) {
this.sexFlag = sexFlag;
}
@Override
public boolean equals(Object o) {
if (this == o) return true;
if (o == null || getClass() != o.getClass()) return false;
Bedroom bedroom = (Bedroom) o;
return sexFlag == bedroom.sexFlag
Objects.equals(place, bedroom.place)
Objects.equals(manager, bedroom.manager)
Objects.equals(bedCount, bedroom.bedCount)
Objects.equals(tableCount, bedroom.tableCount)
Objects.equals(persons, bedroom.persons);
}
@Override
public int hashCode() {
return Objects.hash(place, manager, bedCount, tableCount, persons, sexFlag);
}
@Override
public String toString() {
return "Bedroom{" +
"place='" + place + '\'' +
", manager='" + manager + '\'' +
", bedCount=" + bedCount +
", tableCount=" + tableCount +
", persons=" + persons +

}
}
寝室中住宿的人员类如下：
import java.util.Objects;
public class Person {
private String sno;
private String name;
private String subject;
public String getSno() {
return sno;
}
public void setSno(String sno) {
this.sno = sno;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getSubject() {
return subject;
}
public void setSubject(String subject) {
this.subject = subject;
}
@Override
public boolean equals(Object o) {
if (this == o) return true;
if (o == null || getClass() != o.getClass()) return false;
Person person = (Person) o;
return Objects.equals(sno, person.sno)
Objects.equals(name, person.name)
Objects.equals(subject, person.subject);
}
@Override
public int hashCode() {
return Objects.hash(sno, name, subject);
}
@Override
public String toString() {
return "Person{" +
"sno='" + sno + '\'' +
", name='" + name + '\'' +
", subject='" + subject + '\'' +
'}';
}
}
我给讲概思路：1：第步：设计数据库般像种型宿舍管理系统选用mysql作数据库设计表包括表字段名字段及表间关系2：第二布：确认使用技术作java选用Springmvc作mvc框架毕竟比较灵简单Spring必须用管理事务Hibernate作台数据库管理框架jsp作页面表现层程序比较健壮扩展起比较便3：第二步基础接建立Bean类比类、宿舍类等等映射数据库表字段编写Service层、Dao层等等建立数据处理逻辑4：实现表现层写jsp页面想前台展示内容写jsp面选用技术juqery,js考虑用户体验用ajax实现异步刷新交互5：前台相互通信用juint进行集测试看看数据否按照逻辑准确显示期测试等等嫌麻烦采用ssh框架直接用jsp+servlet写比较简单原理概差层没清晰明
