在IntelliJ IDEA中设置Tomcat的问题 [英] Problems setting up tomcat in intellij idea

问题描述

我正在尝试使用intellij想法创建一个简单的可测试的宁静Web服务.我正在学习本教程: https: //medium.com/@jamsesso/starting-out-with-jersey-apache-tomcat-using-intellij-6338d93ffd40

I'm trying to create a simple test restful web service using intellij idea. I'm following this tutorial: https://medium.com/@jamsesso/starting-out-with-jersey-apache-tomcat-using-intellij-6338d93ffd40

但是，我在运行它时遇到了一些问题.每次运行它后，我每次进入localhost:8080/，它都会向我显示error 404和消息

But, i got some problems running it. Every time i go to localhost:8080/ after running it, it shows me error 404 and the message

The origin server did not find a current representation for the target resource or is not willing to disclose that one exists.

.并且，在intellij中，存在大量错误.我将第一个放在这里:

. And, in intellij, there is a extense list of errors. I'll put the first one here:

13-Jan-2019 15:34:28.861 GRAVE [RMI TCP Connection(3)-127.0.0.1] org.apache.catalina.core.ContainerBase.addChildInternal ContainerBase.addChild: start: 
 org.apache.catalina.LifecycleException: Failed to start component [StandardEngine[Catalina].StandardHost[localhost].StandardContext[]]

在开始时，它显示以下内容:

At the beggining, it shows this:

F:\Java\apache-tomcat-9.0.13\bin\catalina.bat run
[2019-01-13 03:34:27,290] Artifact RestTeste:war exploded: Waiting for server connection to start artifact deployment...
Using CATALINA_BASE:   "C:\Users\vitor\.IntelliJIdea2018.2\system\tomcat\Tomcat_9_0_13_RestTeste"
Using CATALINA_HOME:   "F:\Java\apache-tomcat-9.0.13"
Using CATALINA_TMPDIR: "F:\Java\apache-tomcat-9.0.13\temp"
Using JRE_HOME:        "C:\Program Files\Java\jdk1.8.0_111"
Using CLASSPATH:       "F:\Java\apache-tomcat-9.0.13\bin\bootstrap.jar;F:\Java\apache-tomcat-9.0.13\bin\tomcat-juli.jar"

我认为tomcat可能没有正确的配置，但是我找不到错误的配置.我在intellij和tomcat之间寻找环境变量和java版本，但是我可以确切地说出是否是问题之一. Java_home和catalina_home分别设置为jdk文件夹和tomcat文件夹，从我所看到的来看，版本是正确的.我对这个问题完全迷失了，在超过4个小时内找不到任何解决方案.

I think tomcat is maybe not with the right configs, but i couldn't find the ones that are wrong. I looked for environment variables and java version between intellij and tomcat, but i could say precisely if one of this was the problem. Java_home and catalina_home was set up to jdk folder and tomcat folder, respectively, and from what i saw, the versions were correct. I'm completely lost regarding this problem, and couldn't find any solution in more than 4 hours.

可能是什么问题?

我是否错过了tomcat或intellij中的某些配置步骤?我正在读取tomcat文件夹中的running.txt文件，并按照配置该文件的步骤进行操作，但是没有成功.

Am i missing some configuration step in tomcat or in intellij? I was reading the running.txt file inside of tomcat folder and followed the steps to configure it but no success.

非常感谢！

更新:我尝试做其他事情，因此在这里值得一提.我尝试通过apache tomcat网站下载的.exe进行安装.它工作正常，我启动了它，并在localhost:8080处显示了默认的tomcat页面.然后，我去了intellij，并将这个新版本的tomcat添加到了我的应用程序服务器中，该服务器位于C:\ Program Files \ Apache Software Foundation \ Tomcat 9.0中.当我尝试运行它时，一开始，它给了我一个错误，那就是本地主机已在使用中，但是我关闭了tomcat并再次尝试并成功了.至少是部分.它给我的错误与以前相同，并且仅运行localhost:8080会给我以下消息:源服务器未找到目标资源的当前表示，或不愿意透露该资源的存在."再次.我尝试将我的jre_home变量更改为C:\ Program Files \ Java \ jre1.8.0_191，如yan所建议的那样，但它仍显示使用JRE_HOME:"C:\ Program Files \ Java \ jdk1.8.0_111".如果我在cmd中回显％JRE_HOME％，它将打印jre路径，而不是jdk路径.你们能帮我吗? 要添加应用服务器，我只是选择了tomcat及其路径. 再次输入初始文本:

UPDATE: I tried to do other stuff so it's worth pointing out here. I tried the install through the .exe downloaded in apache tomcat website. It worked fine, i started it and at localhost:8080 it shows me the default tomcat page. I then went to intellij and added this new version of tomcat to my application servers, located in C:\Program Files\Apache Software Foundation\Tomcat 9.0. When i tried to run it, at first, it gave me the error that localhost was already in use, but i closed tomcat and tried again and it worked. At least, partially. It gives me the same errors than before and running only localhost:8080 gives me the message "The origin server did not find a current representation for the target resource or is not willing to disclose that one exists." again. I tried changing my jre_home variable to C:\Program Files\Java\jre1.8.0_191, as the answer from yan suggested, but it continued to show Using JRE_HOME: "C:\Program Files\Java\jdk1.8.0_111". If i echo %JRE_HOME% in cmd it will print the jre path, not the jdk one. Can you guys help me? To add the application server, i simply selected tomcat and the path to it. The initial text, again:

Using CATALINA_BASE:   "C:\Users\vitor\.IntelliJIdea2018.2\system\tomcat\Tomcat_9_0_8_RestTest"
Using CATALINA_HOME:   "C:\Program Files\Apache Software Foundation\Tomcat 9.0"
Using CATALINA_TMPDIR: "C:\Program Files\Apache Software Foundation\Tomcat 9.0\temp"
Using JRE_HOME:        "C:\Program Files\Java\jdk1.8.0_111"
Using CLASSPATH:       "C:\Program Files\Apache Software Foundation\Tomcat 9.0\bin\bootstrap.jar;C:\Program Files\Apache Software Foundation\Tomcat 9.0\bin\tomcat-juli.jar"

推荐答案

确保已在部署"选项卡中添加了工件(请参见下面的屏幕截图)！

Make sure that you added your artifact(s) in the Deployment tab (see screenshot below)!

完成此操作后，您就可以运行项目了，应该没问题.

After do this, you run your project and it should be ok.
