在类W/ClassMapper上找不到字符串的setter或字段

public class ClassMapper {
    private String someField;

    // 正确的setter方法
    public void setSomeField(String someField) {
        this.someField = someField;
    }

    // 可选：添加getter方法以便于读取
    public String getSomeField() {
        return someField;
    }
}

<resultMap id="classMapperResultMap" type="com.example.ClassMapper">
    <result property="someField" column="some_column_in_db"/>
