在tomcat 7.0和tomcat 8.0之间改变什么

我的tomcat应用在openSUSE 13.2上的tomcat 7.0.55上运行良好。在tomcat 7.0和tomcat 8.0之间改变什么

我需要使该应用程序在openSUSE 13.2上的tomcat 8.0.32上工作。我可以成功安装tomcat 8.0.32。

[email protected]:~> java -cp lib/catalina.jar org.apache.catalina.util.ServerInfo 
Server version: Apache Tomcat/8.0.32 
Server built: Feb 22 2016 11:10:58 UTC

OS Version:  3.10.0-123.el7.x86_64

JVM Version: 1.7.0_95-b00 
JVM Vendor:  Oracle Corporation

我没有对文件夹结构或目录或应用程序做任何更改。现在，当我运行它时，它会抛出许多错误，我无法弄清楚如何解决。我们需要在这两个版本之间进行更改？

没什么不寻常的。基本的java罐子。 – praving5

它是由这个例外

Caused by: java.lang.NoSuchMethodError: java.util.concurrent.ConcurrentHashMap.keySet()Ljava/util/concurrent/ConcurrentHashMap$KeySetView;

你应该尝试使用的Java 1.8，而不是1.7造成的。 ConcurrentHashMap的1.8版本的keyset（）方法改变了返回类型http://docs.oracle.com/javase/8/docs/api/java/util/concurrent/ConcurrentHashMap.html#keySet--。

与1.7版本比较：http://docs.oracle.com/javase/8/docs/api/java/util/concurrent/ConcurrentHashMap.html#keySet--)./ConcurrentHashMap.html#keySet%28%29

好的，安装jdk 1.8。我认为tomcat 8.0会自动安装它可以使用的jvm。将在几分钟后发布结果。谢谢。 – praving5

太棒了！这就像一个魅力。谢谢是不够的。自从早上起我就一直在努力。你摇滚！ – praving5

欢迎您:) –

您的机器上是否安装了java 8？看来tomcat 8正在寻找自java 1.8以来增加的ConcurrentHashMap的一种方法

编辑：我刚才看到现在你正在运行jvm 7.0，试用8.0，它应该运行良好。

的Java 8 ConcurrentHashMap.keySet()而在Java 7它返回一个Set<K>（其中K映射键和V映射值）返回一个KeySetView<K, V>。

由于根本原因异常期望KeySetView，因此只需运行Java 8。

对我来说，“tomcat 8.0.23”在JDK 1.8和1.7下运行良好。似乎这个问题在他们的最新版本“tomcat 8.0.32”中被裁剪。正如建议尝试使用JDK 8.这应该有助于解决。

这可能是Tomcat最新版本的一个文档错误;作为他们的在线setup page以及RUNNING.txt（随附可安装），提及它将与“1.7或以上”一起使用。测试成功后，您可能想指出它们。
