Sublime Text 3修改文件后Eclipse不更新，JSF项目浏览器无变化求助

I’ve run into this exact frustration before—external editors not syncing properly with Eclipse’s deployment pipeline can grind your HTML/CSS development to a halt. Let’s walk through the most reliable fixes to get your changes showing up instantly:

1. Enable Eclipse Workspace Auto-Refresh #

Eclipse doesn’t automatically watch for file changes made outside the IDE by default. Fix that:

• Go to Window > Preferences > General > Workspace
• Check both Refresh using native hooks or polling and Refresh on access
• Click Apply/OK. This makes Eclipse pick up edits from Sublime Text in real time.

2. Turn On Automatic Project Builds #

If Eclipse isn’t rebuilding your project when files change, updated resources won’t get deployed to the server:

• Click the Project menu at the top of Eclipse
• Ensure Build Automatically is checked (it should have a checkmark next to it)

3. Tweak Server Publishing Settings #

Even if Eclipse detects changes, it might wait too long to push them to your server:

• Open the Servers view (if hidden, go to Window > Show View > Servers)
• Right-click your server (e.g., Tomcat) and select Properties
• Navigate to the Publishing section
• Choose Automatically publish when resources change
• Set the Publishing interval to 1 second (down from the default 15)
• Click Apply/OK. This ensures Eclipse deploys updates the moment they’re detected.

4. Disable Server-Side Resource Caching #

Most application servers cache static resources (like HTML/CSS) for performance—great for production, but a headache during development:

For Tomcat: #

• Open your server’s context.xml file (either in Eclipse’s Servers project or your Tomcat installation’s conf folder)
• Add <Resources cachingAllowed="false"/> inside the <Context> element. Example:

  <Context>
      <Resources cachingAllowed="false"/>
      <!-- existing server config -->
  </Context>
  

• Restart your server to apply the change.

5. Bypass Browser Caching #

Even if the server sends updated files, your browser might still serve cached versions:

• Use a hard refresh instead of a normal refresh: Ctrl+F5 (Windows/Linux) or Cmd+Shift+R (Mac)
• Or disable caching temporarily in your browser’s dev tools:
  • Open DevTools with F12
  • Go to the Network tab
  • Check the Disable cache box (this works only while DevTools is open)

6. Verify Deployment Assembly #

Double-check that your HTML/CSS files are actually being included in the deployed application:

• Right-click your project in Eclipse > Properties > Deployment Assembly
• Ensure folders containing your HTML/CSS (e.g., WebContent, src/main/webapp) are mapped to the root / of your deployed app
• If missing, click Add > Folder to include them.

Start with the first three steps—they’re the most likely to solve your problem. If not, moving to server and browser caching tweaks should resolve the delay.
