Mybatis 在 insert 之后想获取自增的主键 id

package com.admin.dao.mapper.linkage;
@MyBatisDao
public interface StrategyMapper {
  int insert(Strategy record);
}

package com.admin.dao.mapper.linkage;
@Service
public class StrategyService {

  @Autowired
  private StrategyMapper strategyDao;

  public int insert(Strategy strategy){
      this.strategyDao.insert(strategy);
      int id = strategy.getId();
      System.out.println();
  }
}

<insert id="insert" useGeneratedKeys="true" keyProperty="id" parameterType="com.shengtong.smartlamppost.admin.dao.entity.linkage.Strategy" >
  insert into linkage_strategy (id, strategy_name, priority, 
  status, create_by, create_date, 
  update_by, update_date, remarks
  )
  values (#{id,jdbcType=INTEGER}, #{strategyName,jdbcType=VARCHAR}, #{priority,jdbcType=INTEGER}, 
  #{status,jdbcType=CHAR}, #{createBy.id,jdbcType=VARCHAR}, #{createDate,jdbcType=TIMESTAMP}, 
  #{updateBy.id,jdbcType=VARCHAR}, #{updateDate,jdbcType=TIMESTAMP}, #{remarks,jdbcType=VARCHAR}
  )
  </insert>
