三步走使用Dozer (Do,Po,Vo转换工具)

第一步 把依赖加上

<dependency>
    <groupId>com.github.dozermapper</groupId>
    <artifactId>dozer-core</artifactId>
    <version>6.5.0</version>
</dependency>

第二步,不同属性名的在被转换bean上(Do)注解@Mapping("vo里该字段名称")

 

 

第三步,使用dozer进行转换

 

 

 

测试结果:

user:User(id=3, yonghumingcheng=zhangsan, password=123123, truename=truename1, bumenmingcheng=bumen, gangweijuese=null, beizhu=null, salt=null, root=null, roles=role1,role2,role3, createtime=Sat Feb 15 17:59:10 CST 2020, updatetime=null, p_id=1, state=null, icon=null, sort=null, order=null)
userVo:UserVo(id=3, username=zhangsan, password=123123, truename=truename1, bumenmingcheng=bumen, gangweijuese=null, beizhu=null, salt=null, root=null, roles=role1,role2,role3)

        List<InterxxxxxxxxxxxxxmVo> resultVoList = null;
        //Do列表不为null,进行Do->Vo转换
