java书店系统毕业设计 用户模块（2）

java书店系统毕业设计 用户模块（2）

本文实例为大家分享了java书店系统毕业设计第二篇，供大家参考，具体内容如下

1、用户管理（user.txt）

字段名和顺序

说明：其中的type为int类型，用来表示操作用户的类型。

1——表示为admin，可以进行全部操作

2——表示为能操作图书模块的人员

3——表示为能操作进货模块的人员

4——表示为能操作销售模块的人员

5——表示为能操作库存模块的人员

type用了枚举实现

package cn.hncu.bookStore.user.common;

public enum UserTypeEnum {

AdMIN(1,"超级管理员"),BOOK(2,"图书管理员"),IN(3,"进货管理员"),OUT(4,"销售管理员"),STOCK(5,"库存管理员");

private final int type;

private final String name;

UserTypeEnum(int type,String name){//默认private

this.name =name;

this.type=type;

}

public int getType() {

return type;

}

public String getName() {

return name;

}

public static int getTypeByName(String name){

for(UserTypeEnum utm:UserTypeEnum.values()){

if(utm.getName().equals(name.trim())){

return utm.getType();

}

}

throw new IllegalArgumentException("没有该\""+name+"\"对应的用户类型");//非法参数异常

}

public static String getNameByType(int type){

for(UserTypeEnum utm:UserTypeEnum.values()){

if(utm.getType()==type){

return utm.getName();

}

}

throw new IllegalArgumentException("没有该\""+type+"\"对应的用户类型");//非法参数异常

}

}
