Java Spring集成MapStruct详情

前言：

mapstruct支持spring的依赖注入机制，只须要在@mapper注解中添加componentmodel配置项，并设置为“spring”便可。

待转换的类

@getter
@setter
@tostring
@builder
@allargsconstructor
@noargsconstructor
public class spu {
    private integer id;
    private string name;
    private string caption;
    private string pics;
    private string specs;
    private string unit;
    private integer hot;
    private integer comments;
    private integer agrees;
    private integer recommend;
    private integer status;
    private string service;
    private string info;
    private integer countryid;
    private string addr;
    private localdatetime createtime;
    private localdatetime updatetime;
}

目标类

@getter
@setter
@tostring
@builder
@allargsconstructor
@noargsconstructor
public class spuvo {
    private integer id;
    private string name;
    private string caption;
    private string pics;
    private string specs;
    private string unit;
    private string service;
    private string addr;
}

转换接口

@mapper(componentmodel = "spring")
public interface sputrans {
    list<spuvo> spulist2spuvolist(list<spu> spulist);
}

测试类

@controller
@requestmapping()
public class indexcontroller {
    @resource
    private sputrans sputrans;
    @resource
    private spuservice spuservice;

    @getmapping("/list")
    public modelandview list(modelandview mav) {
        //轮播图
        list<spu> spulist = spuservice.selectall();
  		list<spuvo> spuvolist = sputrans.spulist2spuvolist(spulist);

        mav.addobject("spuvolist", spuvolist);
        mav.setviewname("spu_list");
        return mav;
    }
}
