How to set a boolean at controller level in springboot?

问题

  1. 我有一个名为WalletController的控制器类，我还有另一个具有布尔属性的转换器类。我在我的控制器的每个方法中将该布尔值设置为true。是否有一种方法可以在控制器级别上设置该布尔值，而不是在方法级别上，以便该布尔值只对这个特定的控制器为true？
  3. @RestController
  4. @CrossOrigin(origins = "*")
  5. @RequestMapping("/api/wallet")
  6. public class WalletController {
  8.     private static final Logger logger = LoggerFactory.getLogger(WalletController.class);
  10.     @Autowired
  11.     private VoucherService voucherService;
  13.     @Autowired
  14.     MailManager mailManager;
  16.     @Autowired
  17.     Converter converter;
  19.     // ... （其他方法的定义）
  21.     @CrossOrigin(origins = "*")
  22.     @RequestMapping(value = "/create", method = RequestMethod.POST)
  23.     public @ResponseBody ResponseEntity saveTransaction(@RequestBody CreateTopupDTO createTopupDTO, HttpServletRequest httpServletRequest) {
  24.         //converter.supports = true;
  25.         System.out.println("------------------" + httpServletRequest.getRequestURI());
  26.         return voucherService.createVoucher(createTopupDTO);
  27.     }
  29.     // ... （其他方法的定义）
  31.     @CrossOrigin(origins = "*")
  32.     @RequestMapping(value = "/withdraw", method = RequestMethod.POST)
  33.     public @ResponseBody ResponseEntity createWithdrawRequest(@RequestBody CreateWithdrawDTO withdrawDTO, HttpServletRequest httpServletRequest) {
  34.         //converter.supports = true;
  35.         return voucherService.createWithdrawRequest(withdrawDTO);
  36.     }
  38.     // ... （其他方法的定义）
  40.     // 其他方法的定义...
  42. }

I have a controller class named WalletController, I also have another converter class that have attribute boolean. I am setting that boolean to true at every method in my controller. Is there a way to set that boolean at controller level instead of method level, so that boolean would only be true for this particular controller only?

你可以为转换器类创建自定义的Bean（避免在类上使用@Component注解），并在需要的时候在控制器中进行注入。

例如：

假设你有一个这样的Converter类：

  1. public class Converter {
  3.     private boolean supports = false;
  5.     public boolean isSupports() {
  6.         return supports;
  7.     }
  9.     public void setSupports(boolean supports) {
  10.         this.supports = supports;
  11.     }
  13. }

在一个@Configuration类中创建自定义的Converter Bean。

  1. @Configuration
  2. public class SampleConfig {
  4.     @Bean(name = "converterSupportTrue")
  5.     public Converter beanOne() {
  6.         Converter converter = new Converter();
  7.         converter.setSupports(true);
  8.         return converter;
  9.     }
  10.   
  11.     @Bean(name = "converterSupportFalse")
  12.     public Converter beanTwo() {
  13.         Converter converter = new Converter();
  14.         return converter;
  15.     } 
  17. }

用于测试的控制器：

  1. @Controller
  2. public class FirstController {
  4.     @Autowired
  5.     private Converter converterSupportTrue;
  7.     @GetMapping("/test/support1")
  8.     public void test() {
  9.         System.out.println(converterSupportTrue.isSupports());
  10.     }
  12. }

另一个用于测试的控制器：

  1. @Controller
  2. public class SecondController {
  4.     @Autowired
  5.     private Converter converterSupportFalse;
  7.     @GetMapping("/test/support2")
  8.     public void test() {
  9.         System.out.println(converterSupportFalse.isSupports());
  10.     }
  12. }

你可以在整个应用程序中使用这个Bean，而无需编写样板代码。

英文:

You can create your custom bean for converter class (avoid @Component over the class) and inject it in controller when required.

For example:

Suppose you have a Converter class like this :

  1. public class Converter {
  3. 	private boolean supports = false;
  5. 	public boolean isSupports() {
  6. 		return supports;
  7. 	}
  9. 	public void setSupports(boolean supports) {
  10. 		this.supports = supports;
  11. 	}
  13. }

Create custom Converter bean in a @Configuration class.

  1. @Configuration
  2. public class SampleConfig {
  4. 	@Bean(name = "converterSupportTrue")
  5. 	public Converter beanOne() {
  6. 		Converter converter = new Converter();
  7. 		converter.setSupports(true);
  8. 		return converter;
  9. 	}
  10.   
  11.     @Bean(name = "converterSupportFalse")
  12. 	public Converter beanTwo() {
  13. 		Converter converter = new Converter();
  14. 		return converter;
  15. 	} 
  17. }

Controller to test :

  1. @Controller
  2. public class FirstController {
  4. 	@Autowired
  5. 	private Converter converterSupportTrue;
  7. 	@GetMapping("/test/support1")
  8. 	public void test() {
  9. 		System.out.println(converterSupportTrue.isSupports());
  10. 	}
  12. }

Another controller to test ;

  1. @Controller
  2. public class SecondController {
  4. 	@Autowired
  5. 	private Converter converterSupportFalse;
  7. 	@GetMapping("/test/support2")
  8. 	public void test() {
  9. 		System.out.println(converterSupportFalse.isSupports());
  10. 	}
  12. }

You can use this bean throughout the application without writing boilerplate code.
