这个文件是由于引用json的版本不对引起的，打开pom.xml文件 找到引入json包的配置位置
- <dependency>
- <groupId>org.json</groupId>
- <artifactId>json</artifactId>
- <version>20150729</version>
- </dependency>
修改成：
- <dependency>
- <groupId>org.json</groupId>
- <artifactId>json</artifactId>
- <version>20140107</version>
- </dependency>
***问题解决!
