创建bean时出错，自动连接依赖项注入失败，无法自动连接字段

蔡伟：

卡住了一个异常，下面是日志：

org.springframework.beans.factory.BeanCreationException：创建名称为“ speaker”的bean时出错：自动连接依赖项注入失败；嵌套异常是org.springframework.beans.factory.BeanCreationException：无法自动装配方法：public final void org.mybatis.spring.support.SqlSessionDaoSupport.setSqlSessionTemplate（org.mybatis.spring.SqlSessionTemplate）; 嵌套的异常是java.lang.NoSuchMethodError：org.springframework.core.MethodParameter.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();
        }    
    }
}

陈健：

我相信你配置basePackage的MapperScannerConfigurer不正确。它应该是包含mapper类而不是mapper类本身的包。因此，尝试将更basePackage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>
