eclipse中启动tomcat不产生日志文件-CSDN问答

Tomcat启动闪退且不报错

首先先给大家看看startup.bat的效果 ![图片说明](https://img-ask.csdn.net/upload/201911/03/1572761838_130755.jpg) </br>可以看到没有任何报错，并且log日志文件夹也是空的。所以不知道该怎么排查...（可以百分百确定jdk和jre都是好的，因为在cmd中java、javac、java -version都能显示正确的信息），还有环境变量那些CATALINA_HOME、CATALINA_BASE,path都是已经配置好了的，但是就是启动闪退。</br> 之前也有看很多的博客，他们启动的时候要么有报错信息但是闪退（显然我这个没这么轻松），有的可以通过log查看到是jre的问题（我没有log信息输出），基本的环境变量问题就不谈了。。。大家有没有解决启动闪退不报错的办法呢？因为以前一直是用eclipse，他里面自带了tomcat插件，最近转IDEA所以要配置了QAQ（以前留下的问题终将要解决的呐.....）

tomcat 启动失败该怎么办？

![图片说明](https://img-ask.csdn.net/upload/201810/24/1540392958_805663.png) JSP软件安装过程中把Tomcat以及JDK更改了原始路径。导致教师所给的eclipse无法安装成功。但在Java老师给的eclipse中tomcat启动成功，并在默认页面打开成功。此时新建web文件无果，于是在eclipse中下载了web插件。遂tomcat页面报出404错误。发现原始页面笼罩在了404错误之下。 tomcat启动日志如图。

zookeeper 注册接口速度很慢。每一个接口越5秒，请教

首先是平台为macOS 10.12 ide为eclipse，项目搭载到tomcat7.0 项目为java-web zookeeper使用为 3.4.6 （尝试过最新3.5.2） zoo.cfg配置为 The number of milliseconds of each tick _tickTime=2000_ The number of ticks that the initial synchronization phase can take _initLimit=10_ The number of ticks that can pass between sending a request and getting an acknowledgement _syncLimit=5_ the directory where the snapshot is stored. do not use /tmp for storage, /tmp here is just example sakes. _dataDir=/Users/yukaiji/Documents/tmp/ttehui_ the port at which the clients will connect _clientPort=2181_ the maximum number of client connections. increase this if you need to handle more clients _maxClientCnxns=60_ Be sure to read the maintenance section of the administrator guide before turning on autopurge. http://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_maintenance The number of snapshots to retain in dataDir _autopurge.snapRetainCount=3_ Purge task interval in hours Set to "0" to disable auto purge feature _autopurge.purgeInterval=1_ hosts 设置为本机 ip 本机名称 zkSever.sh. 启动正常。日志文件无错误，jps查看端口正常。 **zkCli.sh. 启动约 5 秒** 目前认为是重点，配置文件反复看了很多次了。 2181 端口正常启动java-web项目，在注册dubbo接口（managerService）的时候，一个大约5秒钟。 ![图片说明](https://img-ask.csdn.net/upload/201612/20/1482234464_970971.png) 在win环境下启动项目整体约30秒，现在启动是两分钟多点。排查了一天半，不清楚因为什么。日志信息就是在dubbo接口注册的时候非常慢。这里还有个问题需要请教，每一个接口的注册，都需要重新连接zookeeper吗？因为每一个接口间隔5s 很均匀。在这里向各位请教。不胜感激。新入门没有币

springboot 配置多库之后,mybatis在控制台不打印sql语句了

JavaTomcat部署远程web启动错误-本地部署远程web启动错误

JavaTomcat启动错误关键错误日志如下： 28-Jun-2019 07:54:44.034 INFO [localhost-startStop-1] org.apache.jasper.servlet.TldScanner.scanJars At least one JAR was scanned for TLDs yet contained no TLDs.

Springboot启动报错一个是找不到url 一个是找不到dao

## 之前一直启动都没有问题，今天突然发现启动不了 ![图片说明](https://img-ask.csdn.net/upload/201910/10/1570671612_490949.jpg) ## 然后我把启动的位置改成@SpringBootApplication(exclude = DataSourceAutoConfiguration.class) ``` package com.mall.shopping.demo; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import

hibernate映射表报错 unknown Oracle major version [0]
