问TLS 签名报错怎么办？

tls 用的是独立托管模式，在本地服务跑是完全没有问题的，放到linux64上（我们自己的服务器上） 报错如下:Apr 16, 2016 92818 PM org.apache.catalina.core.StandardWrapperValve invokeSEVERE: Servlet.service() for servlet SpringMVC in context with path [] threw exception Handler processing failed; nested exception is java.lang.UnsupportedClassVersionError: com/tls/base64_url/base64_url : Unsupported major.minor version 52.0 (unable to load class com.tls.base64_url.base64_url) with root causejava.lang.UnsupportedClassVersionError: com/tls/base64_url/base64_url : Unsupported major.minor version 52.0 (unable to load class com.tls.base64_url.base64_url)
