Spring boot 配置Controller字段映射

在项目开发的过程中，后端实体类Model需要遵循驼峰命名规则，Controller请求却需要返回下划线格式的变量名，或者其他根据需求的变量名，这时可以使用jackson实现

• 引入依赖

    com.fasterxml.jackson.core
    jackson-databind
    2.5.3

• 实体类加注解 

可以加在属性上，对set和get方法同时生效，也可以加在set或者get方法上，分别影响接口传入值和返回值

1. package com.grandtech.aquacultureinsurance.model;
   
   import com.fasterxml.jackson.annotation.JsonIgnore;
   import com.fasterxml.jackson.annotation.JsonProperty;
   import org.apache.commons.lang.StringUtils;
   
   import java.sql.Timestamp;

       }

           return gmtModified;
       }
   
       public void setGmtModified(Timestamp gmtModified) {
           this.gmtModified = gmtModified;
       }
   }
   

   然后正常的网络请求就可以看到

已经名称带下划线了，传参也可以用这个名字了
