解决方法:
这是杰克逊数据绑定jar的问题.在您的jar屏幕截图中,可以看到版本2.4.5的jar正在解析中&仅在jackson-databind jar版本2.6.0中引入withDefaultPrettyPrinter方法时使用.请更正jar版本以解决此问题.
Caused by: java.lang.NoSuchMethodError: com.fasterxml.jackson.databind.SerializationConfig.
withDefaultPrettyPrinter(Lcom/fasterxml/jackson/core/PrettyPrinter;)
Lcom/fasterxml/jackson/databind/SerializationConfig;
