自mybatis3.1.0开始，如果你无需使用原生枚举，可配置默认枚举来省略扫描通用枚举配置 默认枚举配置

1、配置文件配置枚举所在的包

#配置枚举 支持通配符 * 或者 ; 分割

mybatis-plus.type-enums-package=com.iscas.biz.mp.test.model.enums

mybatis-plus.configuration.default-enum-type-handler=org.apache.ibatis.type.EnumOrdinalTypeHandler

2、定义一个枚举，在需要存入数据库的字段上加上@EnumValue注解

package com.iscas.biz.mp.test.model.enums;

import com.baomidou.mybatisplus.annotation.EnumValue;

import com.fasterxml.jackson.annotation.JsonCreator;

import com.fasterxml.jackson.annotation.JsonValue;

import com.fasterxml.jackson.annotation.JsonView;

import com.iscas.biz.mp.test.model.TestEntity;

import lombok.Getter;

import java.util.Objects;

/**

* //TODO

*

* @author zhuquanwen

* @vesion 1.0

* @date 2020/4/5 15:23

* @since jdk1.8

*/

public enum SexEnum /*implements IEnum*/ {

/**

* 男

* */

MAN(1, "男"),

/**

* 女

* */

WOMEN(2, "女");

@EnumValue

private final int code;

@JsonValue

public int getCode() {

return this.code;

}

public String getDescription() {

return description;

}

private final String description;

SexEnum(int val, String description) {

this.code = val;

this.description = description;

}

@JsonCreator

public static SexEnum getByCode(int code) {

for (SexEnum value : SexEnum.values()) {

if (Objects.equals(code, value.getCode())) {

return value;

}

}

return null;

}

/*

@Override

public Integer getValue() {

return code;

}*/

}

3、测试实体使用枚举

package com.iscas.biz.mp.test.model;

import com.iscas.biz.mp.test.model.enums.SexEnum;

import lombok.Data;

/**

* //TODO

*

* @author zhuquanwen

* @vesion 1.0

* @date 2020/4/5 15:22

* @since jdk1.8

*/

@Data

public class TestEntity {

private String name;

private SexEnum sex;

}

4、测试读取和存储带有枚举的实体

package com.iscas.biz.mp.test.controller;

import com.iscas.biz.mp.test.mapper.TestEntityMapper;

import com.iscas.biz.mp.test.model.enums.SexEnum;

import com.iscas.biz.mp.test.model.TestEntity;

import com.iscas.templet.common.BaseController;

import com.iscas.templet.common.ResponseEntity;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.web.bind.annotation.*;

import java.util.List;

/**

* //TODO

*

* @author zhuquanwen

* @vesion 1.0

* @date 2020/4/5 15:22

* @since jdk1.8

*/

@RestController

@RequestMapping("/testEntity")

public class TestMpEnumController extends BaseController {

@Autowired

private TestEntityMapper testEntityMapper;

@GetMapping("/get")

public ResponseEntity testEntity() {

ResponseEntity response = getResponse();

List testEntities = testEntityMapper.selectList(null);

response.setValue(testEntities);

return response;

}

@PostMapping("/post")

public ResponseEntity testSaveEntity(@RequestBody TestEntity testEntity) {

ResponseEntity response = getResponse();

int insert = testEntityMapper.insert(testEntity);

response.setValue(insert);

return response;

}

}
