# Migration from Legacy View API
|
|
|
|
Legacy API (`@View`, `ViewEngine`, `Renderer`, `Template`) has been removed.
|
|
|
|
## Replace annotations
|
|
|
|
- `@View("page")` -> `@Page("page")`
|
|
- `@View(value = "x", fragment = true)` -> `@Partial(template = "x")`
|
|
|
|
`@Page` and `@Partial` must be declared on classes extending `ViewHandler`.
|
|
|
|
## Replace handler return contract
|
|
|
|
Before (legacy):
|
|
|
|
```java
|
|
public Object handle(Request req, Response res) {
|
|
return Map.of("name", "Flash");
|
|
}
|
|
```
|
|
|
|
Now:
|
|
|
|
```java
|
|
public ViewModel render(Request req) {
|
|
return ViewModel.of("name", "Flash");
|
|
}
|
|
```
|
|
|
|
## Replace engine integration
|
|
|
|
- Implement `ViewEngineAdapter` directly.
|
|
- Or use `ViewEngineType.THYMELEAF`.
