项目信息：
项目是用maven构建的，用的Spring+Mybatis+Oracle，后台和页面以json数据通信，用的fastjson做的中间转换器：

<mvc:annotation-driven><!-- 返回值类型的转换器 --><mvc:message-converters register-defaults="true"><!-- 将Jackson2HttpMessageConverter的默认格式化输出为true --><!-- 配置Fastjson支持 --><beanclass="com.alibaba.fastjson.support.spring.FastJsonHttpMessageConverter"><property name="supportedMediaTypes"><list><value>text/html;charset=UTF-8</value><value>application/json</value></list></property><property name="features"><list><!-- 输出key时是否使用双引号 --><!-- <value>QuoteFieldNames</value>是否输出值为null的字段<value>WriteMapNullValue</value>数值字段如果为null,输出为0,而非null<value>WriteNullNumberAsZero</value>List字段如果为null,输出为[],而非null<value>WriteNullListAsEmpty</value>字符类型字段如果为null,输出为"",而非null<value>WriteNullStringAsEmpty</value>Boolean字段如果为null,输出为false,而非null<value>WriteNullBooleanAsFalse</value>null String不输出<value>WriteNullStringAsEmpty</value>null String也要输出<value>WriteMapNullValue</value>Date的日期转换器<value>WriteDateUseDateFormat</value> --><value>WriteMapNullValue</value><value>QuoteFieldNames</value> <value>WriteDateUseDateFormat</value></list></property></bean></mvc:message-converters></mvc:annotation-driven>

异常现象：对应实体的json数据从页面往后台传时，若包含中文，就报如上异常；若无中文，则正常。

异常原因：运行环境问题，编译的JDK和运行的不一致导致。

查看项目发现用的fastjosn版本为：1.2.24
查看其编译JDK：1.8.0_112
而项目构建JDK：1.6



解决办法：把fastjson版本换为用1.6编译的1.1.41后解决。

附：查看jar包JDK版本的方法：
地址：http://www.itnpc.com/news/web/146215427561876.html

1.查看.jar包中的META-INF\MANIFEST.MF

          使用winrar等压缩软件打开.jar包，查看META-INF\MANIFEST.MF中的内容，Build-Jdk属性就是JDK的版本，比如：

Build-Jdk: 1.8.0_91

      说明其JDK版本为1.8.0_91。 

      但是，如果一个.jar文件中，如果没有这个字段，就必须通过下面一种方法来查看。

2.通过反编译.class文件来查看

      解压.jar包，能得到.class文件。用JDK自带的javap反编译.class文件，用如下命令：

javap -verbose Configuration.class11

      查看得到的信息中，major version属性的内容，如下

major version: 5211

      说明这个.class文件是由JDK1.8编译得到的。

• J2SE 6.0 = 50 (0x32 hex)

• J2SE 5.0 = 49 (0x31 hex)

• JDK 1.4 = 48 (0x30 hex)

• JDK 1.3 = 47 (0x2F hex)

• JDK 1.2 = 46 (0x2E hex)

• JDK 1.1 = 45 (0x2D hex)

      ［注意］一个.jar包中可能有多个.class文件，每个.class的JDK版本可能会不一样（编译器多个项目设置不同） 。

3.如何设置Eclipse导出.jar的JDK版本

      我们可以在同一台机器上安装多个JDK，然后在eclipse中选择不同版本的JDK来导出.jar包。

      Project右键->Properties->JavaCompiler中的JDK Compliance选项下，有Use Compliance from execution environment 选择JDK版本。

      ［注意］如果一个.jar依赖于多个Project，必须将每个Project的JDK版本都选择一致。
