spring boot测试类junit无法注入实体对象类？

Question

问题遇到的现象和发生背景

可以注入Service,但是就是无法注入实体对象

问题相关代码，请勿粘贴截图

package com.yuyouya.householdledger;

import com.yuyouya.householdledger.service.FamilyService;
import com.yuyouya.householdledger.user.Family;
import org.junit.jupiter.api.Test;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.web.WebAppConfiguration;

import javax.annotation.Resource;

@SpringBootTest
class HouseholdledgerApplicationTests {

    @Test
    void contextLoads() {
    }

    @Resource
    private FamilyService familyService; //可以注入
    @Resource
    Family family; //无法注入

    @Test
    void insertFamily() {
        family.setCode("haha1");
        family.setName("很爱很爱你！");
        System.err.println(family);
//        Family family = new Family();
//        family.setName("测试家庭5");
//        familyService.insertFamily(family);
    }
}

运行结果及报错内容

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'com.yuyouya.householdledger.HouseholdledgerApplicationTests': Injection of resource dependencies failed; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'com.yuyouya.householdledger.user.Family' available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {@javax.annotation.Resource(shareable=true, lookup=, name=, description=, authenticationType=CONTAINER, type=class java.lang.Object, mappedName=)}

我的解答思路和尝试过的方法

网上搜的与启动类名称一样不存在，因为测试后面加的Test
service为什么可以注入，实体对象为什么不可以？

我想要达到的结果

可以在测试类成功注入实体对象类！

你可以new一个，或者在实体类上加@Component
