解决The resource identified by this request is only capable of generating responses with characteristics not acceptable according to the request "accept" headers.

SpringMVC中当在浏览器中输入对应的MappingUrl时，报The resource identified by this request is only capable of generating responses with characteristics not acceptable according to the request "accept" headers.

错误的意思是：说是指定的资源已经找到，但它的MIME类型和客户在Accpet头中所指定的不兼容

@ResponseBody返回json格式的数据，而浏览器接受的是text/html;charset=UTF-8文本类型

解决方法：

1：在pom.xml中添加json所需要的依赖

 <!--json所需要的依赖-->
    <dependency>
      <groupId>com.fasterxml.jackson.core</groupId>
      <artifactId>jackson-core</artifactId>
      <version>2.7.3</version>
    </dependency>

    <dependency>
      <groupId>com.fasterxml.jackson.core</groupId>
      <artifactId>jackson-databind</artifactId>
      <version>2.7.3</version>
    </dependency>

    <dependency>
      <groupId>com.fasterxml.jackson.core</groupId>
      <artifactId>jackson-annotations</artifactId>
      <version>2.7.3</version>
    </dependency>

2:在springmvc配置文件中配置对应的bean

<!--转化json-->
    <bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">
        <property name="messageConverters">
            <list>
                <!--json视图拦截器，读取到@ResponseBody的时候去配置它-->
                <ref bean="mappingJacksonHttpMessageConverter"/>
            </list>
        </property>
    </bean>
    <!--json转化器，它可以将结果转化-->
    <bean id="mappingJacksonHttpMessageConverter" class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">
        <property name="supportedMediaTypes">
            <list>
                <value>application/json;charset=UTF-8</value>
            </list>
        </property>
    </bean>

重新启动不在报错了
