Question

被异常卡住，下面是日志：

org.springframework.beans.factory.BeanCreation异常：创建名为扬声器的bean时出错：注入自动生成的依赖项失败；嵌套异常是org.springframework.beans.factory.BeanCreation异常：无法自动连接方法：公共最终无效org.mybatis.spring.support.SqlSessionDaoSupport.setSqlSessionTem板（org.mybatis.spring.SqlSessionTemboard）；嵌套异常是java.lang.NoSuch方法错误：org.springframework.core.方法arameter.getNestedParameterType（）Ljava/lang/Class

java web服务：

@WebService
public class voiceRecognition extends SpringBeanAutowiringSupport {
    @Autowired
    private Speaker speaker;


    @WebMethod
    public void test() {

        String userid = "111";
        String enrollmentid = "111";

        try{
        String test1 = speaker.getEnrollmentId(userid);  
        System.out.println(test1);
        }
        catch (Exception e)
        {
            e.printStackTrace();
        }    
    }
}

我相信您在MapperScannerConfiguration中配置的basePackage不正确。它应该是包含映射器类的包，而不是映射器类本身。因此，尝试将basePackage更改为：

<bean id="mapperSpeaker" class="org.mybatis.spring.mapper.MapperScannerConfigurer">
    <property name="basePackage" value="ph.com.aub.mapper" />
    <property name="sqlSessionFactoryBeanName" value="sqlSessionFactorySpeaker" />
</bean>
