我正在尝试将 sql 语句添加到 java spring 中的映射器中，但是当我尝试时出现错误
I'm trying to add sql statements into mapper in java spring but gets an error when I try to
一开始以为是controller的问题，试着加上那些statements的ID，还是报错。有问题的代码在代码的中间。与上面的工作正常。
我不知道如何处理这个东西 :( 现在已经苦苦挣扎了几个小时。
任何帮助将非常感激。

您已经在映射器顶部用 id = "sample" 声明了 resultMap。在您的 select 语句中，您使用 resultType = "sample"。所以像这样改变你的 select 语句
<select id="getReply" parameterType="sampleVO" resultMap="sample">
或者，如果您想使用 resultType 而不是 resultMap，那么您需要确保已经创建了一个名为 sample 的 class。
1.最重要的是，检查你的错误日志。
TypeException: Could not resolve type alias 'egovframework.example.sample.service.sampleVO'.
Cause: java.lang.ClassNotFoundException: Cannot find class: egovframework.example.sample.service.sampleVO
2。为 sampleVO 添加类型别名标签 class.
<mapper namespace="egovframework.example.sample.service.impl.SampleMapper">
<typeAlias alias="sampleVO" type="egovframework.example.sample.service.sampleVO" />
...
</mapper>
此别名用于以下属性。
parameterType="sampleVO"
3。检查 "sampleVO.java".
的路径
没问题？接下来..
4.修改以下代码。输入 -> class
<resultMap id="sample" type="egovframework.example.sample.service.sampleVO">
到
<resultMap id="sample" class="egovframework.example.sample.service.sampleVO">
一开始以为是controller的问题，试着加上那些statements的ID，还是报错。有问题的代码在代码的中间。与上面的工作正常。

您已经在映射器顶部用 id = "sample" 声明了 resultMap。在您的 select 语句中，您使用 resultType = "sample"。所以像这样改变你的 select 语句
<select id="getReply" parameterType="sampleVO" resultMap="sample">
或者，如果您想使用 resultType 而不是 resultMap，那么您需要确保已经创建了一个名为 sample 的 class。
1.最重要的是，检查你的错误日志。
TypeException: Could not resolve type alias 'egovframework.example.sample.service.sampleVO'.
Cause: java.lang.ClassNotFoundException: Cannot find class: egovframework.example.sample.service.sampleVO
2。为 sampleVO 添加类型别名标签 class.
<mapper namespace="egovframework.example.sample.service.impl.SampleMapper">
<typeAlias alias="sampleVO" type="egovframework.example.sample.service.sampleVO" />
...
</mapper>
此别名用于以下属性。
parameterType="sampleVO"
3。检查 "sampleVO.java".
的路径没问题？接下来..
4.修改以下代码。输入 -> class
<resultMap id="sample" type="egovframework.example.sample.service.sampleVO">
到
<resultMap id="sample" class="egovframework.example.sample.service.sampleVO">
