需求：使用批量插入後，需要insert之後的每一條記錄的ID

註意：Mybatis3.3.1的版本以後支持批量插入後返回主鍵ID

示例：

domin.java：

public class User
{
    private int d;
    private String name;
    private String pwd;
    public long getId() {
        return id;
    }
    public void setId(long id) {
        this.id = id;
    }
    public String getName() {
        
 
return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    public String getPwd() {
        return pwd;
    }
    public void setPwd(String pwd) {
        this.pwd = pwd;
    }
}

mapper.java：

public interface UserMapper{
    int insertTest(List<User> user);
}
 

mapper.xml：

<insert id="insertTest" parameterType="java.util.List" useGeneratedKeys="true" keyProperty="id">
   insert into user (name,pwd) values
    <foreach collection="list" item="item" index="index" separator=","> 
         (#{item.name},#{item.pwd}) 
     </foreach> 
</insert
 
>
