安装完zookeeper后启动服务端报错如如上

错误信息很明显说了地址已经被占用，以为一般的tomcat默认设置了自动部署，需要修改tomcat的 server.xml 属性

我用的tomcat8，默认配置如下

  <Host appBase="webapps" autoDeploy="true"  name="localhost" unpackWARs="true">

修改为 

  <Host appBase="webapps" autoDeploy="false" deployOnStartup="false" name="localhost" unpackWARs="true">

在启动就好了。

注意：如果是在eclipse中修改你项目栏左侧server离得server.xml ,开始我修改的是我安装tomcat的硬盘的文件，每次都会自动还原成默认

[小梅哥FPGA] 如何通过动态重配置实现FPGA时钟的实时频率/相位/占空比调整？

PLL和MMCM是实际存在的硬件电路，用以对输入时钟的负面变化，如抖动、频率变化、相位偏移、占空比失真等进行处理。基于该表，用户在初始化Clk_Wiz后，只需要计算好所需的频率、相位、占空比对应的设置值，使用Xil_Out32函数配置对应寄存器即可。通过上述步骤，在平时的开发调试过程中，亦或是一些对于时钟可能有着实时性要求的设计（如数据采集、图像处理）里，我们便可以在无需重新修改设计的前提下，通过AXI4总线来完成对时钟频率、相位的调控，从而达到缩短设计周期以及让设计适应更多场景的目的。

如果错误使用ListA，由于是一个大类下的子类，所以表现上是没有问题的，但是入参类不同，进行解析的时候就会解析失败，程序会判定你要调用的并不是getId(ListB类)这个接口，继续会去找xxx.getIds(ListA类)的接口，但是根本就没有xxx.getIds(ListA类)，未找到就会报调用失败。stream.tolist() 和 collect(Collectors.toList())虽然返回的都是List，但是他们其实是list下对应的不同的子类。正常去数据库中查询，需要的是ListB类。
