Detailed explanation of Tomcat's Server Options

1. Configuration

By default, the first two are not checked and should be checked:

( 1 ) The first option of Server Options is Serve modules without publishing

By default, when the project is deployed to tomcat, the plug-in will copy the project files to the wtpwebapps directory that displays the Server path in the previous configuration item Server Locations, that is, the directory where the current wrokspace is located . In the metadata subdirectory, if my wrokspace is D:\workspace , then the directory is: D:\workspace\.metadata\.plugins\org.eclipse.wst.server.core\tmp0\wtpwebapps .

But if you select the above option, the project file will not be published to this directory for running, but:

The web resource directory is: WebContent of the web project , that is, the src/main/webapp directory of the Maven web project

The class file directory is: the output directory of the currently configured class file, that is, the target/classes directory of the Maven project

( 2 ) Timeouts

By default, start is 45 seconds and stop is 15 seconds. You may need to modify start to a larger value. This means that if the startup time exceeds the specified time and the startup is not completed, an error will be reported. When our project starts up and it takes a long time, this is obviously not what we want, so we need to modify this value.

Check Server Options-> Serve Modules without publishing. If you do not check it, the Web server will be restarted continuously when you modify the class file . If the Web project takes a long time to start, you also need to modify the timeout time, which can be set in Timeouts.

在Cotext節點中有一個reloadable='true'屬性，將它改為false，可以在修改java文件后不用重啟服務器即可生效，但是不包括新建java文件、添加方法和變量的操作

2. Browse files

Files generated separately by the Context node:

The Context node in conf/server.xml in the original Tomcat installation directory (after checking the second option, this node does not exist in server.xml):

<Host appBase="webapps" autoDeploy="true" name="localhost" unpackWARs="true">
  <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs" pattern="%h %l %u %t &quot;%r&quot; %s %b" prefix="localhost_access_log" suffix=".txt"/>
  <Context docBase="D:\workspace\workspace(eclipse)\Shop\WebContent" path="/Shop" reloadable="true" source="org.eclipse.jst.jee.server:Shop">
    <Resources>
      <PreResources base="D:\workspace\workspace(eclipse)\Shop\build\classes" classLoaderOnly="false" className="org.apache.catalina.webresources.DirResourceSet" internalPath="/" webAppMount="/WEB-INF/classes"/>
    </Resources>
  </Context>
</Host>

3. Reasons

1. Check the first one to prevent warnings:

Warning: A docBase D:/Tomcat/webapps/Shop inside the host appBase has been specified, and will be ignored

After checking, it means that Tomcat will directly use the content under WebContent in eclipse without publishing to <workspace>.metadata.pluginsorg.eclipse.wst.server.coretmp0webapps
And delete the related resources under tmp0webapps,
At the same time, the serveModulesWithoutPublish=true in <workspace>.metadata.pluginsorg.eclipse.wst.server.coreservers.xml and the <Context> configuration in tmp0/conf/server.xml will be modified

2. Check the second one to prevent warnings:

Warning: [SetPropertiesRule]{Server/Service/Engine/Host/Context} Setting property 'source' to 'org.eclipse.jst.j2ee.server:strut2demo' did not find a matching property.

The reason for the [SetPropertiesRule] warning is that the source attribute is no longer supported in the context node of server.xml in Tomcat 6.0 and above. The specific instructions are as follows:

For Tomcat 6, unlike Tomcat 4.x, it is NOT recommended to place <Context> elements directly in the server.xml file. This is because it makes modifying the Context configuration more invasive since the main conf/server.xml file cannot be reloaded without restarting Tomcat.

Checking English spelling is useless, so disable spell checking here. Location: General->Editors->Text Editors->Spelling , uncheck Enable spell checking

There is another check that can be canceled : Validation , check Suspend all validators

Display line number location: General->Editors->Text Editors , check Show line numbers

Change the default encoding of jsp pages to utf-8 location: Web->JSP Files , Encoding to ISO 10646/Unicode ( UTF-8 )
