在公司代码中，用了一大堆的枚举，看得我好懵逼。下面开始看看枚举怎么写和怎么用。
一、枚举的写法
关于枚举的写法，网上好多这方面的知识。这里直接贴一个我自己写的枚举类的代码。
（1）代码片段一
package com.tomtop.application.libraries.constentEnum;
/**
* 包材领用状态枚举类
* @author zeng.xiao.yan
* @date Jun 5, 2017 1:04:40 PM
* @version V1.0
*/
public enum UseStatusEnum {
PACKING_NOT_USE(1), // 未领用
PACKING_HAS_USED(2), // 已领用
PACKING_BACK_USE(3); // 已打回
private Integer useStatus;
private UseStatusEnum(int useStatus) {
this.useStatus = useStatus;
}
public Integer getUseStatus() {
return useStatus;
}
}

二、枚举类在代码中的用法
（1）代码片段一
// 枚举使用案例01
productPackingRecord.setUseStatus(UseStatusEnum.PACKING_NOT_USE.getUseStatus()); //设为未领用状态
2
1
// 枚举使用案例01
2
productPackingRecord.setUseStatus(UseStatusEnum.PACKING_NOT_USE.getUseStatus()); //设为未领用状态
// 枚举使用案例01
productPackingRecord.setUseStatus(UseStatusEnum.PACKING_NOT_USE.getUseStatus()); //设为未领用状态
2
1
// 枚举使用案例01
2
productPackingRecord.setUseStatus(UseStatusEnum.PACKING_NOT_USE.getUseStatus()); //设为未领用状态
注意：这里调用getUseStatus这个方法才能返回枚举常量的值。
（2）代码片段二
// 枚举使用案例02
public Map<String,String> getOptions(){
Map<String,String> options = new LinkedHashMap<>();
B2bInvoiceStatusEnum[] statusEnums = B2bInvoiceStatusEnum.values(); // 获得枚举对象数组
// 遍历枚举对象
for (B2bInvoiceStatusEnum b2bInvoiceStatusEnum : statusEnums) {
// eg：put("10","待开票")
options.put(b2bInvoiceStatusEnum.getStatus().toString(), b2bInvoiceStatusEnum.getText());
}
return options;
}
// 枚举使用案例03
/** （3）保存发票，发票状态设为'待关务部审核发票' */
invoiceInfo.setStatus(B2bInvoiceStatusEnum.WAIT_CUSTOMS_AUDIT_INVOICE.getStatus());
session.save(invoiceInfo);
17
1
// 枚举使用案例02
2
public Map<String,String> getOptions(){
3
Map<String,String> options = new LinkedHashMap<>();
4
B2bInvoiceStatusEnum[] statusEnums = B2bInvoiceStatusEnum.values(); // 获得枚举对象数组
5
// 遍历枚举对象
6
for (B2bInvoiceStatusEnum b2bInvoiceStatusEnum : statusEnums) {
7
// eg：put("10","待开票")
8
options.put(b2bInvoiceStatusEnum.getStatus().toString(), b2bInvoiceStatusEnum.getText());
9
}
10
return options;
11
}
12
13
14
// 枚举使用案例03
15
/** （3）保存发票，发票状态设为'待关务部审核发票' */
16
invoiceInfo.setStatus(B2bInvoiceStatusEnum.WAIT_CUSTOMS_AUDIT_INVOICE.getStatus());
17
session.save(invoiceInfo);
// 枚举使用案例02
public Map<String,String> getOptions(){
Map<String,String> options = new LinkedHashMap<>();
B2bInvoiceStatusEnum[] statusEnums = B2bInvoiceStatusEnum.values(); // 获得枚举对象数组
// 遍历枚举对象
for (B2bInvoiceStatusEnum b2bInvoiceStatusEnum : statusEnums) {
// eg：put("10","待开票")
options.put(b2bInvoiceStatusEnum.getStatus().toString(), b2bInvoiceStatusEnum.getText());
}
return options;
}
// 枚举使用案例03
/** （3）保存发票，发票状态设为'待关务部审核发票' */
invoiceInfo.setStatus(B2bInvoiceStatusEnum.WAIT_CUSTOMS_AUDIT_INVOICE.getStatus());
session.save(invoiceInfo);
x
1
// 枚举使用案例02
2
public Map<String,String> getOptions(){
3
Map<String,String> options = new LinkedHashMap<>();
4
B2bInvoiceStatusEnum[] statusEnums = B2bInvoiceStatusEnum.values(); // 获得枚举对象数组
5
// 遍历枚举对象
6
for (B2bInvoiceStatusEnum b2bInvoiceStatusEnum : statusEnums) {
7
// eg：put("10","待开票")
8
options.put(b2bInvoiceStatusEnum.getStatus().toString(), b2bInvoiceStatusEnum.getText());
9
}
10
return options;
11
}
12
13
// 枚举使用案例03
14
/** （3）保存发票，发票状态设为'待关务部审核发票' */
15
invoiceInfo.setStatus(B2bInvoiceStatusEnum.WAIT_CUSTOMS_AUDIT_INVOICE.getStatus());
16
session.save(invoiceInfo);
