mybatis org.apache.ibatis.binding.BindingException：无效的绑定语句（未找到）

时间：2015-11-02 13:41:57

标签： java spring spring-mvc spring-mybatis

我正在使用带有Spring-Mybatis的Spring MVC来使用注释（@Insert，@Select等）执行基本的CRUD操作并获得以下异常

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)但是这并没有解决我的问题，因为它使用XML（UserMapper.xml）映射来查询我使用java接口的问题（{{1} }）带注释。

异常堆栈跟踪： 

UserMapper.java

springConfig.xml

国籍 POJO课程，

<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
  <property name="dataSource" ref="dataSource" />
  <property name="typeAliasesPackage" value="com.spring.mybatisdemo.model"/>
  <property name="mapperLocations" value="classpath*:com/spring/mybatis/mappers/*.xml" />
</bean>

<bean id="sqlSession" class="org.mybatis.spring.SqlSessionTemplate">
  <constructor-arg index="0" ref="sqlSessionFactory" />
</bean>

<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
  <property name="basePackage" value="com.spring.mybatisdemo.mappers" />
</bean>

我在查询中使用注释，下面是我在UserMapper.java界面中的相关代码，

public class Nationality {  
  private Long nationalityId;
  private String name;

  //ignoring getters and setters
}

调用上述方法，

@Select("SELECT nationalityId, name FROM nationality where nationalityId = #{nationalityId} ")
public Nationality selectNationality(Long nationalityId);

在Nationality nationality = userService.selectNationalityById(new Long("1")); 中，我注入了UserMapper bean并将其用作

UserServiceImpl.java

我用于选择userMapper.selectNationality(nationalityId); 工作正常的查询

teamById

和

userMapper.getTeamById(teamId)

和控制台中相应的teamById查询，

@Select("SELECT teamId, name FROM TEAM WHERE teamId = #{teamId}")
public Team getTeamById(Long teamId);

我无法理解为什么只有国籍有这个问题，而Team类的相同方法工作正常。我的代码中有什么问题可以获取国籍数据？

1 个答案:

答案 0 :(得分：2)

我曾经犯过一个类似的错误，结果发现目录不正确 如果UserMapper的命名空间为com.mybatisdemo.mappers.UserMapper，请确保映射器位置为src/resources/com/mybatisdemo/mappers/ 有时我们可能会创建一个名为com.mybatisdemo.mappers的目录，然后它的位置变为src/resources/com.mybatisdemo.mappers，这是错误的。
