将重复的实体类复制到cloud-api-commons中

业务实体类

package com.gcl.springcloud.entities;

import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;

@Data
@AllArgsConstructor
@NoArgsConstructor
public class Payment {

    private Long id;
    private String serial;

}

结果包装类

package com.gcl.springcloud.entities;

import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;

@Data
@AllArgsConstructor
@NoArgsConstructor
public class CommonResult<T> {

    private Integer code;
    private String message;
    private T data;

    public CommonResult(Integer code, String message){
        this(code, message, null);
    }

}

将支付模块和消费模块的实体类删除，并在pom中引入

 <dependency>
     <groupId>org.gcl.learn</groupId>
     <artifactId>cloud-api-commons</artifactId>
     <version>${project.version}</version>
 </dependency>
