javax.servlet.servletexception: could not resolve view with name 'login' in servlet with name 'grailsdispatcherservlet'

This error message typically indicates that the Grails framework is unable to find a view with the name 'login' in your application. Here are some steps you can take to troubleshoot this issue: 1. Check if the view exists: Make sure that the view file 'login.gsp' exists in the correct directory (usually under grails-app/views). If it doesn't exist, create it. 2. Check the spelling and capitalization: Ensure that the name of the view is spelled correctly and that the capitalization matches exactly. For example, if your view is named 'Login.gsp', make sure you're using 'Login' instead of 'login'. 3. Check your controller: Verify that your controller is forwarding to the correct view name. For example, if your controller code looks like this: ``` def login() { render(view: 'login') } ``` 4. Check your URL mapping: Make sure that your URL mapping is set up correctly to map requests to the correct controller action. Here's an example of a URL mapping that maps requests to the login action of a UserController: ```python "/login"(controller: 'user', action: 'login') ``` 5. Clear your browser cache: Sometimes, your browser may be caching an old version of the page, which can cause issues. Try clearing your browser cache and reloading the page. If none of these steps work, try searching for similar issues online or posting on a forum for help. [2023-12-04 16:56:34 | AI写代码神器 | 308点数解答]
