Bean实体类转换

对象copy工具有很多，像dozer，orika等等。项目中对接搜索商品接口，原先是对接的是第三方平台的选单网，后面发现搜索类别实在太少了，只有一种like模糊搜索，后来打算用维易接口，搜索种类相对丰富。两者的商品实体类属性字段都各有差异，所以就通过从维易获取的结果转成选单的，使用了类型装换。搞了个demo，做个记录，方便以后查看。

1.BaseDto

package com.slx.outer.bean;


import sun.reflect.generics.reflectiveObjects.NotImplementedException;

abstract class BaseDto<T> {

    public BaseDto() {
    }

    public BaseDto(T t) {
    }

    abstract public T convertTo();

    public void setStatus(String status){
        throw new NotImplementedException();
    }

    public void check() {
    }


    @Override
    public String toString() {
        return GsonBuilderUtil.buildGson().toJson(this);
    }
}

2.GsonBuilderUtil

package com.slx.outer.bean;

import com.google.gson.Gson;
import com.google.gson.GsonBuilder;


public class GsonBuilderUtil {

    public static Gson buildGson() {
        return new GsonBuilder()
                .disableHtmlEscaping()
                .enableComplexMapKeySerialization()
                .setDateFormat("yyyy-MM-dd HH:mm:ss")
                .create();
    }
}

3.UserDO

package com.slx.outer.bean;

import java.io.Serializable;

/**
 * @Author: slx
 * @Date: 2019/6/15 20:32
 */
public class UserDO extends BaseDto<UserDTO> implements Serializable {

    private String userName;

    private String passWord;

    private String userType;

    private String mobile;

    public String getUserName() {
        return userName;
    }

    public void setUserName(String userName) {
        this.userName = userName;
    }

    public String getPassWord() {
        return passWord;
    }

    public void setPassWord(String passWord) {
        this.passWord = passWord;
    }

    public String getUserType() {
        return userType;
    }

    public void setUserType(String userType) {
        this.userType = userType;
    }

    public String getMobile() {
        return mobile;
    }

    public void setMobile(String mobile) {
        this.mobile = mobile;
    }

    @Override
    public UserDTO convertTo() {
        UserDTO userDTO = new UserDTO();
        userDTO.setUserName(this.userName);
        userDTO.setUserType(this.userType);
        userDTO.setMobile(this.mobile);
        return userDTO;
    }

    @Override
    public String toString() {
        return "UserDO{" +
                "userName='" + userName + '\'' +
                ", passWord='" + passWord + '\'' +
                ", userType='" + userType + '\'' +
                ", mobile='" + mobile + '\'' +
                '}';
    }
}

4、UserDTO

package com.slx.outer.bean;

/**
 * @Author: slx
 * @Date: 2019/6/15 20:33
 */
public class UserDTO {

    private String userName;

    private String userType;

    private String mobile;


    public String getUserName() {
        return userName;
    }

    public void setUserName(String userName) {
        this.userName = userName;
    }

    public String getUserType() {
        return userType;
    }

    public void setUserType(String userType) {
        this.userType = userType;
    }

    public String getMobile() {
        return mobile;
    }

    public void setMobile(String mobile) {
        this.mobile = mobile;
    }

    @Override
    public String toString() {
        return "UserDTO{" +
                "userName='" + userName + '\'' +
                ", userType='" + userType + '\'' +
                ", mobile='" + mobile + '\'' +
                '}';
    }
}

5.测试

package com.slx.outer.bean;

import org.junit.Test;

/**
 * @Author: slx
 * @Date: 2019/6/15 20:38
 */
public class UserTest {

    @Test
    public void Test() {
        UserDO userDO = new UserDO();
        userDO.setUserName("shuPush");
        userDO.setPassWord("123456");
        userDO.setUserType("VIP");
        userDO.setMobile("15866666666");
        UserDTO userDTO = userDO.convertTo();
        System.out.println(userDO.toString());
        System.out.println(userDTO.toString());
    }
}

结果：

UserDO{userName='shuPush', passWord='123456', userType='VIP', mobile='15866666666'}
UserDTO{userName='shuPush', userType='VIP', mobile='15866666666'}
