我正在将Spring MVC与Spring-Mybatis结合使用,以使用Annotations(@Insert
,@Select
等)执行基本的CRUD操作,并得到以下异常org.apache.ibatis.binding.BindingException: Invalid bound statement (not found):
这是一个相关的问题mybatis spring mvc application, getting Invalid bound statement (not found),但它不能解决我的问题,因为它使用XML(UserMapper.xml
)映射进行查询,而我在Java接口(UserMapper.java
)中使用了批注。
异常堆栈跟踪:

国籍 POJO类,
public class Nationality {
private Long nationalityId;
private String name;
//ignoring getters and setters
}
我在查询中使用注释,下面是来自UserMapper.java接口的相关代码,
@Select("SELECT nationalityId, name FROM nationality where nationalityId = #{nationalityId} ")
public Nationality selectNationality(Long nationalityId);
像上面那样调用上面的方法,
Nationality nationality = userService.selectNationalityById(new Long("1"));
在
UserServiceImpl.java
中,我注入了UserMapper bean并像这样使用它,userMapper.selectNationality(nationalityId);
我用于选择
teamById
的同一查询工作正常,userMapper.getTeamById(teamId)
和
@Select("SELECT teamId, name FROM TEAM WHERE teamId = #{teamId}")
public Team getTeamById(Long teamId);
以及控制台中相应的teamById查询,

[artifact:mvn] 2015-11-02 18:51:20 DEBUG getTeamById:54 - <== Total: 1
我不明白为什么只有国籍有这个问题,而团队班用相同的方法却能正常工作。我的代码中提取国籍数据可能是什么问题?
最佳答案
我曾经犯过类似的错误,结果发现目录不正确。
如果UserMapper的名称空间是com.mybatisdemo.mappers.UserMapper
,请确保mapper-locations是src/resources/com/mybatisdemo/mappers/
。
有时我们可能创建一个名为com.mybatisdemo.mappers
的目录,那么它的位置原来是src/resources/com.mybatisdemo.mappers
,这是错误的。
