    java.lang.UnsupportedClassVersionError: org/springframework/web/SpringServletContainerInitializer : Unsupported major.minor version 52.0
    这个异常是说你编译用的jre和运行用的jre不一致。比如你开发用jdk1.8，但是在运行环境中用的jdk11，就hu已出现上述问题。而version 52.0指的是jdk8。具体对应如下：
    49 = Java 5
    50 = Java 6
    51 = Java 7
    52 = Java 8
    53 = Java 9
    54 = Java 10
    55 = Java 11
    56 = Java 12
    57 = Java 13
    58 = Java 14
