错误是这样的

但是控制台没有报错

SpringMVC配置文件是这样的

	<context:component-scan base-package="com.face.controller" annotation-config="true"></context:component-scan>
	
	<mvc:annotation-driven>
        <mvc:message-converters>
            <bean class="org.springframework.http.converter.StringHttpMessageConverter">
                <property name="supportedMediaTypes">
                    <list>
                        <value>text/plain;charset=UTF-8</value>
                        <value>text/html;charset=UTF-8</value>
                    </list>
                </property>
            </bean>
            <bean class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter">
                <property name="supportedMediaTypes">
                    <list>
                        <value>application/json;charset=UTF-8</value>
                    </list>
                </property>
            </bean>
        </mvc:message-converters>
    </mvc:annotation-driven>

Controller里面是这样的

@RequestMapping(value = "test.do",method = RequestMethod.GET)
	@ResponseBody
	public ServerResponse<Result> test(){
		Result result = new Result(20);
		return ServerResponse.createBySuccess(result);
	}

这是我按照老师电商项目自己搭的其他项目，我想问下老师，是不是哪里漏了什么？或者哪里配置错了？如何解决？
