従業員.java

public class Employee {
  private List<Emp> list = new ArrayList<Emp>();
  public List<Emp> getList() {
    return list;
  }
  public void setList(List<Emp> list) {
    this.list = list;
  }
}

Emp.java

public class Emp {
  public Emp(int id, String name) {
    this.id = id;
    this.name = name;
  }
  private int id;
  private String name;
  public int getId() {
    return id;
  }
  public void setId(int id) {
    this.id = id;
  }

TestDAO.java

public interface TestDAO {
public Integer insertEmployeeList(List<Emp> empList) throws SQLException;
}

Main.java

public class Main {
   public static void main (String args[]) {
       TestDAO tm = session.getMapper(TestDAO.class);
       Employee e = new Employee();
       Emp e11 = new Emp(123,"abc");
       Emp e12 = new Emp(456,"def");
       e.getList().add(e11);
       e.getList().add(e12);
       tm.insertEmployeeList(e.getList());
   }
}

私が得ている例外は次のとおりです。

The error may involve com.XXXX.sample.test.dao.TestDAO.insertEmployeeList-Inline

私はMySQLをデータベースとして使用しているので、数回試した後、これが私にとってどのように機能したかです。

<insert id="insert" parameterType="java.util.List">
        INSERT INTO games (
        id,
        game_id,
        game_vendor,
        game_code,
        game_name,
        game_type)
        VALUES
        <foreach collection="list" item="element" index="index" open="(" separator="),("  close=")">
            #{element.id},
            #{element.gameId},
            #{element.gameVendor},
            #{element.gameCode},
            #{element.gameName},
            #{element.gameType},
       </foreach>
    </insert>
</mapper>
