Java POJO作为Mybatis中插入的参数

我有一个名为UserDTO的域对象

这是我的mapper.xml文件配置

<insert id="insertUser" useGeneratedKeys="true" keyProperty="id" parameterType="com.myapp.dto.UserDTO">
    insert into
    tblusers(username,password,email,phone,role,is_active,security_question,securtiy_answer,first_name,last_name)
    values(#{username},#{password},#{email},#{phone},#{role,typeHandler=com.greenflight.typehandlers.StringArrayListTypeHandler},#{is_active},#{security_question},#{securtiy_answer},#{first_name},#{last_name})
</insert>

我浏览了mybatis的文档，没有找到关于如何将域对象作为参数发送的好例子

有人能告诉我你是如何在UserDAO中实现CreateNewUserDAO方法的吗？我认为你给电话号码的值是错误的（可能是设置了错误的值）

{phone}在像这样更改映射程序文件之后，我能够插入记录

我改变了这个

<insert id="insertUser" useGeneratedKeys="true" keyProperty="id" parameterType="com.greenflight.dto.UserDTO">
    insert into
    tblusers(username,password,email,phone,role,is_active,security_question,securtiy_answer,first_name,last_name)
    values(#{username},#{password},#{email},#{phone},#{role,typeHandler=com.greenflight.typehandlers.StringArrayListTypeHandler},#{is_active},#{security_question},#{securtiy_answer},#{first_name},#{last_name})
</insert>

适用于HashMap但不适用于POJO不知道为什么这不是问题这会插入记录，但不会返回插入的记录id，这是

useGeneratedKeys

和

keyProperty

的初始用法。在这种情况下，您可以使用HashMap

<insert id="insertUser" useGeneratedKeys="true" keyProperty="id" parameterType="com.greenflight.dto.UserDTO">
    insert into
    tblusers(username,password,email,phone,role,is_active,security_question,securtiy_answer,first_name,last_name)
    values(#{username},#{password},#{email},#{phone},#{role,typeHandler=com.greenflight.typehandlers.StringArrayListTypeHandler},#{is_active},#{security_question},#{securtiy_answer},#{first_name},#{last_name})
</insert>

<insert id="insertUser"  parameterType="com.greenflight.dto.UserDTO">
    insert into
    tblusers(username,password,email,phone,role,is_active,security_question,securtiy_answer,first_name,last_name)
    values(#{username},#{password},#{email},#{phone},#{role,typeHandler=com.greenflight.typehandlers.StringArrayListTypeHandler},#{is_active},#{security_question},#{securtiy_answer},#{first_name},#{last_name})
</insert>

   useGeneratedKeys="true" keyProperty="id"
