任何人都可以告诉我我在上面的代码中做错了什么吗？或者告诉我在 application.property 文件
中声明变量的任何其他方法
看起来 Spring 在这里试图做的是将 ${crossOrigin} 的值注入到您的方法中。
- 在
findLocation 中，它没有中断，因为没有方法参数可以在其中注入值
- 在
btnSearchClick 中，有多个参数并且它没有尝试注入值
- 有一个参数，它试图将
${crossOrigin} 的值注入 AccountMaintenanceSave saveObj
您应该只将 ${crossOrigin} 注入 class 顶部的 @CrossOrigin？像这样：
@RestController
@CrossOrigin(origins = "${crossOrigin}")
@RequestMapping("/api.spacestudy.com/SpaceStudy/Admin/Account")
public class AccountController {
@Autowired
AccountService accService;
...
}
并以这种方式访问变量。您需要从控制器方法中删除 @Value 注释。
您还需要在 application.properties:
中指定来源名称
crossOrigin=http://localhost:4200
