tomcat部署项目时出错

Injection of autowired dependencies failed

自动装配失败
第一、xml配置文件不对
第二、注解没加
serviceImpl中的@Service和@Autowired
controller中的@Controller和@Autowired
第三 、包冲突

Failed to start component [StandardEngine[Catalina].StandardHost[localhost].StandardC)

错误代码

    <!-- 错误配置 servlet的servlet-name 同servlet-mapping中的servlet-name不符 -->      <servlet>        <servlet-name>taotao-portal</servlet-name> <!-- 错误 -->          <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>        <init-param>            <param-name>contextConfigLocation</param-name>            <param-value>classpath:spring/springmvc.xml</param-value>        </init-param>        <load-on-startup>1</load-on-startup>    </servlet>    <servlet-mapping>        <servlet-name>taotao-manager</servlet-name> <!-- 错误 -->          <url-pattern>*.html</url-pattern>    </servlet-mapping>
