Spring Boot + Mybatis plus + Vue3 + Element Plus 截取年份

记一次，前端传String类型（2022）的年份到后台，后台响应类型为 Date类型（yyyy-MM-dd）怎么实现等值匹配
前端组件代码：
`

		<el-form-item label="年份">
			<el-date-picker
				v-model="state.queryForm.startTime"
				type="year"
				placeholder="请选择年份"
				format="YYYY"
				value-format="YYYY"
				/>
		</el-form-item>`

后端获取请求参数：
`

@Override

public PageResult<WrProjectVO> page(WrProjectQuery query) {

    //查询参数
    Map<String, Object> params = getParams(query);
    //开始分页
    IPage<WrProjectEntity> page = getPage(query);
    params.put(Constant.PAGE,page);

    //数据列表
    List<WrProjectEntity> list = baseMapper.getList(params);

    return new PageResult<>(WrProjectConvert.INSTANCE.convertList(list), page.getTotal());
}`

获取getParams(query) 请求参数，以Map形式进行匹配
`

	private Map<String, Object> getParams(WrProjectQuery query) {
		Map<String, Object> params = new HashMap<>();
		params.put("startTime",query.getStartTime());
		params.put("orgId",query.getOrgId());
		params.put("name",query.getName());
		return params;
		}`

Mapper.xml操作
`

<select id="getList" resultType="net.maku.system.entity.WrProjectEntity">
	select a.id,a.code,a.name,a.startTime,a.endTime ,f.personnel,n.contracts,a.checkedStatus ,a.checkedMemo  from wr_project a
	left join sys_org b on a.departmentId = b.id
	left join (select e.project_id,count(e.project_id) as personnel from wr_project_emp_relation  e group by e.project_id)  f
	on a.id = f.project_id
	left join (select m.projectId,count(1) as contracts from wr_project_contract_relation m
	left join wr_contract_info p
	on m.contractId = p.id
	where p.flag = 1
	group by m.projectId ) n
	on a.id = n.projectId where 1=1 and  a.deleted = 0 and b.deleted = 0
	<if test="orgId!=null and orgId.trim() != ''">
		and b.id = #{orgId}
	</if>
	<if test="name!=null and name.trim() != ''">
		and a.id = #{name}
	</if>
	<if test="startTime != null and startTime != ''">
		<![CDATA[ and EXTRACT(year FROM a.startTime) =   #{startTime} ]]>
	</if>
	order by a.update_time desc
</select>`
