生成枚举类代码

1. 创建通用model枚举类封装对象

package com.ruoyi.coordination.enums;import java.io.Serializable;public class SelectBean implements Serializable {private String seKey;private String seValue;public String getSeKey() {return seKey;}public void setSeKey(String seKey) {this.seKey = seKey;}public String getSeValue() {return seValue;}public void setSeValue(String seValue) {this.seValue = seValue;}
}

2. 创建对应接口返回前台的枚举对象下拉框类型

package com.ruoyi.coordination.enums;public enum TaskTypeEnum {TOPIC("1","课题"),COMMUNICATION("2","沟通"),DESIGN("3","设计"),DEVELOP("4","开发"),TEST("5","测试"),DELIVER("6","交付");private String label;private String value;public String getLabel() {return label;}public void setLabel(String label) {this.label = label;}public String getValue() {return value;}public void setValue(String value) {this.value = value;}private TaskTypeEnum(String label, String value) {this.label = label;this.value = value;}}

3. 在对应控制层，编写接口返回给前台数据

@RequiresPermissions("coordination:teamTaskInfo:list")@GetMapping("/getTaskTypeEnum")public AjaxResult getTaskTypeEnum() {SelectBean bean;List<SelectBean> listBean = null;listBean = new ArrayList<SelectBean>();for (TaskTypeEnum taskTypeEnum : TaskTypeEnum.values()) {bean = new SelectBean();bean.setSeKey(taskTypeEnum.getLabel());bean.setSeValue(taskTypeEnum.getValue());listBean.add(bean);}return AjaxResult.success(listBean);}

枚举类自带一些很实用的方法：valueOf() ,values()等。valueOf();  它的作用是传来一个字符串，然后将它转变为对应的枚举变量。前提是你传的字符串和定义枚举变量的字符串一摸一样，区分大小写。如果你传了一个不存在的字符串，那么会抛出异常。values():  这个方法会返回包括所有枚举变量的数组

4. 使用接口测试类工具，检验是否能返回准确数据

{"msg": "操作成功","code": 200,"data": [{"seKey": "1","seValue": "课题"},{"seKey": "2","seValue": "沟通"},{"seKey": "3","seValue": "设计"},{"seKey": "4","seValue": "开发"},{"seKey": "5","seValue": "测试"},{"seKey": "6","seValue": "交付"}]
}
