Description

As a downstream of #3485, this task needs you to add(do not delete any existing annotations) more simpler client annotations.

For example, below is how we use client annotation now:

@RestController
@RequestMapping("/order")
@ShenyuSpringCloudClient("/order")
public class OrderController {
    
    @PostMapping("/save")
    @ShenyuSpringCloudClient("/save")
    public OrderDTO save(@RequestBody final OrderDTO orderDTO) {
        orderDTO.setName("hello world spring cloud save order");
        return orderDTO;
    }
}

Does it seem a little repetitive? We can realize combined annotation through @AliasFor and org.springframework.core.annotation.AnnotatedElementUtils#findMergedAnnotation.

Notice: the newly added annotation needs to be compatible with all functions of other frameworks !

Use simplified annotations like below:

@RestController
@ShenyuRequestMapping("/order")
public class OrderController {
    
    @ShenyuPostMapping("/save")
    public OrderDTO save(@RequestBody final OrderDTO orderDTO) {
        orderDTO.setName("hello world spring cloud save order");
        return orderDTO;
    }
}

You are welcome to make suggestions !
