2018-03-20 13:32:01.022 ERROR 13152 --- \[ost-startStop-1\] o.a.catalina.core.AprLifecycleListener   : An incompatible version \[1.1.32\] of the APR based Apache Tomcat Native library is installed, while Tomcat requires version \[1.2.14\]

#### 原因分析： ####

字面意思就是当前版本为1.1.32，需要重新下载1.2.14以上版本。分析SpringBoot的tomcat为内置环境，所以将新版本文件放在java安装目录下即可。

Apache把 httpd的底层库与上层应用逻辑分离，底层库单独发行，底层这就是Apache Portable Runtime Library，简称APR。

APR在跨平台方面，支持多种平台，主要有：

UNIX variants Windows Netware Mac OS X OS/2

APR把很多常用功能都封装好了，内容非常丰富，主要有：

>  Atomic operations
> 
> Dynamic Shared Object loading
> 
> File I/O
> 
> Locks (mutexes, condition variables, etc)
> 
> Memory management (high performance allocators)
> 
> Memory-mapped files
> 
> Multicast Sockets
> 
> Network I/O
> 
> Shared memory
> 
> Thread and Process management
> 
> Various data structures (tables, hashes, priority queues, etc)

#### 解决办法： ####

1.下载对应版本文件，链接如下：

http://archive.apache.org/dist/tomcat/tomcat-connectors/native/

2.解压后，在bin目录下找到tcnative-1.dll文件，我springboot环境为win10，64位系统，选择了x64文件下的dll文件。![20180320215859595][]

3.将dll文件保存到jdk的bin目录中或者是jre的bin目录中，前提要求java的环境变量已经设置好（在高级设置-环境变量中设置查看）。

4.重新启动SpringBoot程序，即可。

启动信息可以看出，版本信息为1.6.2，错误消息没了。
