优化下列代码: private final ApplicationProperty applicationProperty; private final DeveloperProperty developerProperty; @Autowired public PropertyController(ApplicationProperty applicationProperty, DeveloperProperty developerProperty) { this.applicationProperty = applicationProperty; this.developerProperty = developerProperty; } @GetMapping("/property") public Dict index() { return Dict.create().set("applicationProperty", applicationProperty).set("developerProperty", developerProperty); }

优化后的代码如下，主要是使用了Lombok的注解简化了代码：

@RestController
@RequestMapping("/property")
@RequiredArgsConstructor(onConstructor = @__(@Autowired))
public class PropertyController {
    private final ApplicationProperty applicationProperty;
    private final DeveloperProperty developerProperty;

    @GetMapping
    public Dict index() {
        return Dict.create()
                .set("applicationProperty", applicationProperty)
                .set("developerProperty", developerProperty);
    }
}

使用`@RestController`注解代替了`@Controller`和`@ResponseBody`，使用`@RequiredArgsConstructor`注解代替了构造方法，并且在注解中使用了Lombok的`@Autowired`注解，省略了构造方法中的`@Autowired`注解。

同时，将`@GetMapping`注解中的URL从`/property`修改为默认值，省略了URL参数。
