mybatis-plus使用@EnumValue处理枚举类型的示例代码

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<integer>*/ {

  /**
   * 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<testentity> 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;
  }

}
