spring - mybatis spring mvc 应用，得到 Invalid bound statement (not found)

Question

这是我第一个使用spring 3.2.4的mybatis spring mvc应用，mybatis-spring-1.2.1

当我尝试调用我的网络服务时，我得到了错误::

org.springframework.web.util.NestedServletException: Request processing failed; 
nested exception is org.apache.ibatis.binding.BindingException: Invalid bound 
statement (not found): 
org.mydomain.formulary.drugmaster.dao.DrugMasterDao.getDrugsWithAlert

我一定遗漏了一些明显的东西。感谢您的帮助

这是我的关联文件:applicationContext.xml

<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
    <property name="dataSource" ref="formularyDb" />
    <property name="configLocation"  value="file:/web/sites/drugformulary-spring/config/mybatis-config.xml" />
</bean>

<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
    <property name="basePackage" value="org.mydomain.formulary.mappers" />
</bean>
<bean id="DrugMasterDao" class="org.mybatis.spring.mapper.MapperFactoryBean">
    <property name="mapperInterface" value="org.mydomain.formulary.drugmaster.dao.DrugMasterDao" />
    <property name="sqlSessionFactory" ref="sqlSessionFactory" />
</bean>

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

映射器文件 -->/classes/org/mydomain/formulary/mappers/drugmasterDao.xml

<mapper namespace="org.mydomain.formulary.drugmaster.dao.DrugMasterDao">

<select id="getDrugsWithAlert" parameterType="int" resultType="org.mydomain.formulary.drug_master.model.DrugMasters">
    Select drug_id,drug_name,drug_alert_date,drug_alert_source, rownum
    from (select drug_id,drug_name,to_char(drug_alert_datetime,'MM/DD/YYYY') as drug_alert_date ,drug_alert_source, rownum
    from drug_master
    where drug_status ='A' and length(drug_alert) > 0
    order by drug_alert_datetime DESC )
    where
    <if test="_parameter != null">
        rownum &lt; #{count}
    </if>
</select>
</mapper>

映射文件 -->/classes/org/mydomain/formulary/drugmaster/dao/DrugMasterDao.java

public interface DrugMasterDao {
    public List<DrugMasters> getDrugsWithAlert(int count);
}

Controller 文件 -->/classes/org/mydomain/formulary/drugmaster/controller/DrugMasterController.java

@Controller
public class DrugMasterController {
@Autowired
DrugMasterService drugMasterService;


@RequestMapping(value = "/drugmaster/withalerts/count/{count}", method = RequestMethod.GET)
public String withAlerts(ModelMap model, @PathVariable int count) {

    List<DrugMasters> drugs = drugMasterService.getDrugsWithAlert(count);

    return null/*for now*/;

}
}    

服务文件 -->/classes/org/mydomain/formulary/drugmaster/service/DrugMasterServiceImpl.java

@Service
public class DrugMasterServiceImpl implements DrugMasterService {

    @Autowired
    DrugMasterDao drugMasterDao;

    public List<DrugMasters> getDrugsWithAlert(int count){
        return drugMasterDao.getDrugsWithAlert(count);
    }
}

mybatis-configfile -->

<configuration>
<settings>
    <setting name="cacheEnabled" value="false" />
    <setting name="lazyLoadingEnabled" value="false" />
</settings>
</configuration>

Answer 1

我在寻找我的错误时搜索了这个答案。它实际上与OP的问题无关，但异常(exception)是相同的，这个问题在谷歌中非常明显。

就我而言，我忘记更改映射器命名空间

<mapper namespace="pl.my.package.MyNewMapper">

这导致了同样的问题。
