浅谈mybatisPlus的Ipage分页和map参数的问题

Map params= new HashMap();
params.put("name","张三");
params.put("age","23");

List<Map<String,Object>> selectList(@Param("params") HashMap  params);

<select id="selectList" resultType="java.util.HashMap">

<if test="name != '' and name != null">
    AND name=#{name}
</if>
<if test="age != '' and age != null">
    AND age=#{age}
</if>

IPage selectAll(IPage page,@Param("params") HashMap  params);
<select id="selectAll" resultType="java.util.HashMap">

<if test="params.name != '' and params.name != null">
    AND name=#{params.name}
</if>
<if test="params.age != '' and params.age != null">
    AND age=#{params.age}
</if>

public interface ExampleMapper {
    IPage<EntityDto> selectEntityAndPage(@Param("param") Entity param, Page<Entity> page);
}

  <select id="selectEntityAndPage" parameterType="cn.com.example.enetity.Entity " resultType="cn.com.example.dto.EntityDto">
    select id, name from table
  </select>

IPage<EntityDto> selectEntityAndPage(Page<Entity> page, @Param("param") Entity param);
