Spring WebMVC 4.1返回json时导致的 406(Not Acceptable)问题

1.问题现象Tomcat7+Spring4.1.3，返回json字符串时发生406错误

引用

POST http://localhost:8080/ARP/resouces/publishRes.do 406 (Not Acceptable)
The resource identified by this request is only capable of generating responses with characteristics not acceptable according to the request "accept" headers

所用服务器：
Apache Tomcat/7.0.54

2.具体实现

@RequestMapping(value ="/publishRes",method= RequestMethod.POST)
	@ResponseBody
	public AjaxResultVO publishRes(HttpServletRequest request){
		
		AjaxResultVO resultVo = new AjaxResultVO();
		
		resultVo.setSuccess(false);
		resultVo.setErrCode("500");
		resultVo.setExecMsg("查询成功");
		return resultVo;
	}

3.网上调查
按照问题现象在网上搜了一下类似问题不少，代表性的有以下几篇：

The resource identified by this request is only capable of generating responses with characteristics
Spring MVC + JSON = 406 Not Acceptable
Spring 3 MVC And JSON Example

4.0.9使用了网上所说的：

<dependency>  
    <groupId>org.codehaus.jackson</groupId>  
    <artifactId>jackson-mapper-asl</artifactId>  
    <version>1.9.10</version>  
</dependency>

\spring-webmvc-4.0.9.RELEASE-sources\org\springframework\web\servlet\view\json\MappingJacksonJsonView.Java

import org.codehaus.jackson.JsonEncoding;  
import org.codehaus.jackson.JsonGenerator;  
import org.codehaus.jackson.map.ObjectMapper;  
import org.codehaus.jackson.map.SerializationConfig;

而4.1.0开始，使用了：

<dependency>  
    <groupId>com.fasterxml.jackson.core</groupId>  
    <artifactId>jackson-databind</artifactId>  
    <version>2.5.1</version>  
</dependency>

spring-webmvc-4.1.0.RELEASE-sources\org\springframework\web\servlet\view\json\AbstractJackson2View.java

import com.fasterxml.jackson.annotation.JsonView;  
import com.fasterxml.jackson.core.JsonEncoding;  
import com.fasterxml.jackson.core.JsonGenerator;  
import com.fasterxml.jackson.databind.ObjectMapper;  
import com.fasterxml.jackson.databind.SerializationFeature;

6.解决问题
引入fasterxml的jar包，改回spring4.1.4，问题解决。
7.后记：就在要发表文章的时候，在下方预览中看到一篇
Spring MVC 4.1.4 RESTFUL风格返回JSON数据406错误处理

在spring4.X中删除了啊MappingJacksonHttpMessageConverter类文件，可以使用MappingJackson2HttpMessageConverter替换但是启动仍然会报异常
Caused by: java.lang.NoClassDefFoundError: com/fasterxml/jackson/core/JsonProcessingException 解决办法是在pom文件中引入一下jar包

<dependency>
   <groupId>com.fasterxml.jackson.core</groupId>
   <artifactId>jackson-core</artifactId>
   <version>2.5.1</version>
</dependency>
<dependency>
   <groupId>com.fasterxml.jackson.core</groupId>
   <artifactId>jackson-databind</artifactId>
   <version>2.5.1</version>
</dependency>
