- 一、問題描述
- 二、問題分析
-
- 1.主機名解析耗時長
- 2.TomcatEmbeddedWebappClassLoader同步加載class性能低
一、問題描述
說明：本地使用idea開發工具，啟動很快，但是部署到生産庫，啟動比較慢，有時甚至啟動失敗卡死！使用jstack列印線程dump,結果如下：

二、問題分析
1.主機名解析耗時長
從dump資訊1可以看出，主線程一直停留在at java.net.InetAddress.getLocalHost(InetAddress.java:1501),也就是主機名解析上。
java.lang.Thread.State: RUNNABLE
at java.net.Inet6AddressImpl.lookupAllHostAddr(Native Method)
at java.net.InetAddress$2.lookupAllHostAddr(InetAddress.java:929)
at java.net.InetAddress.getAddressesFromNameService(InetAddress.java:1324)
at java.net.InetAddress.getLocalHost(InetAddress.java:1501)
- locked <0x00000006c010e838> (a java.lang.Object)
編寫測試類，在伺服器上執行，測試結果，有時可以瞬間執行完畢，有時需要5~10秒！！！
import java.net.InetAddress;
import java.net.UnknownHostException;
public class Test {
public static void main(String[] args) throws UnknownHostException {
System.out.println(System.currentTimeMillis());
System.out.println(InetAddress.getLocalHost());
System.out.println(System.currentTimeMillis());
}
}
原因：運維人員設定了hostname，但是并未将hostname映射，增加到/etc/hosts中
解決辦法：
hostname
hostnamectl set-hostname cas-server1
vim /etc/hosts
#追加以下内容
192.168.1.220 cas-server1
2.TomcatEmbeddedWebappClassLoader同步加載class性能低
cas 5.3 服務端 springboot内置tomcat，首次通路登入頁面非常慢，使用外置tomcat正常。以下是使用jstack列印的線程dump，确認是org.springframework.boot.context.embedded.tomcat.TomcatEmbeddedWebappClassLoader加載日志類慢導緻的！！！

cas 5.3預設使用，springboot 1.5 版本的tomcat增加synchronized關鍵字加載class，而springboot 2.x使用ParallelWebappClassLoader加載class，加載class的效率提升數倍以上，啟動速度和登入頁面首次通路速度也提升數倍。

解決辦法：
1.更換為jttey（jttey生成的war無法直接在tomcat中運作）；
2.更新springboot版本，1.5->2.x（cas server更新springboot版本較麻煩，jar包沖突不易解決）。
備注：jar包沖突主要是由于cas-server-webapp-tomcat中包含了幾乎所有的cas核心包，且依賴的jar包版本大部分寫死，更新springboot版本難度較大。
<dependency>
<groupId>org.apereo.cas</groupId>
<artifactId>cas-server-webapp${app.server}</artifactId>
<version>${cas.version}</version>
<type>war</type>
<scope>runtime</scope>
</dependency>
<!--截取上面的war包依賴的spring-boot-starter-web包舉例說明-->

<!--省略-->
3.更換為undertow（推薦）
<!-- app.server could be -jetty, -undertow, -tomcat, or blank if you plan to provide appserver -->
<app.server>-undertow</app.server>
server:
undertow:
accesslog:
enabled: true
dir: logs

# 指定工作者線程個數，預設為 I/O 線程個數的 8 倍

# 設定 HTTP POST 内容的最大長度，預設不做限制
