Spring Boot Circular View Path Error Explained
Issue
When running a Spring Boot MVC application, you may encounter the following error:
Circular view path [index]: would dispatch back to the current handler URL [/index] again. Check your ViewResolver setup!
This error causes the application to fail to render the view. What causes this and how can it be fixed?
Solution
The Circular view path error in Spring Boot usually occurs when a controller method returns a view name that matches the request mapping, causing an infinite loop. For example:
@GetMapping("/index")
public String index() {
return "index";
}
If you have a view template named index.html in your templates directory, make sure your controller does not map to the same path as the view name. Instead, use:
@GetMapping("/")
public String index() {
return "index";
}
Or rename the view or mapping to avoid the conflict. Always check your ViewResolver configuration as well.
