• springmvc 整合 camunda

    参考官网：Process Engine 配置 | docs.camunda.org

    一 POM

    注意：

    1 低版本c3p0会报错：Method com/mchange/v2/c3p0/impl/NewProxyResultSet.isClosed()Z 

    千万记得要删除Target包下的旧版本！！！

    com.mchange
    c3p0
    0.9.5.4

    2 低版本jackson会报错：com.fasterxml.jackson.databind.exc.InvalidDefinitionException

    
    com.fasterxml.jackson.core
    jackson-databind
    2.9.8

    3 如果先前创建过Camunda会报错：HistoryLevel mismatch

    删除Camunda，重新创建

    4 springmvc4 中 web.xml配置的Log4jConfigListener

    在springmvc5中已经弃用，所以需要修改

    参考：spring5.0解决Log4jConfigListener过期问题_dabaishaflyw的博客-CSDN博客

    三 官网中配置了：

    但我的datasource已经在application.xml中配置了。

    所以此处注释了
