在 Spring Boot 应用程序中不起作用的方面

问题描述 投票：0回答：1

我正在使用 Aspects 创建一个 Spring boot 应用程序，但它不起作用。它没有被拾取。

我在自定义配置类中定义了EnableAspectJAutoProxy。

@Configuration
@EnableAspectJAutoProxy(proxyTargetClass = true)
public class AppConfig {

@Bean
public ModelMapper modelMapper() {
    return new ModelMapper();
}

查看了有关堆栈溢出的多种解决方案，我发现添加@Component可能会解决我的问题，但是当我添加@Component时，我的应用程序无法启动。

请找出下面的错误-

我的代码-

资源文件-

@RestController
@RequestMapping("/data")
public class PtbBankResource {

     @GetMapping("/ret")
     @ValidateUser(headerName = "Authorization")
     public ResponseEntity<?> getCall()
     {
          return ResponseEntity.ok().body("data Successfull");
     }
}

自定义注释-

@Component
@Retention(RetentionPolicy.RUNTIME)
@Target(ElementType.METHOD)
public @interface ValidateUser {    
    String headerName() default "";
}

方面类-

@Aspect
public class AuthAspect {

private static final Logger logger = LoggerFactory.getLogger(AuthAspect.class);

@Autowired
PtbUtils ptbUtils;

@Around(value = "execution(* *(..)) && @annotation(ValidateUser)")
public Object authValidation(ProceedingJoinPoint joinPoint, ValidateUser validateUser) throws Throwable
{
    logger.info("Inside authValidation class");

    String headerName = validateUser.headerName().isEmpty() ? HttpHeaders.AUTHORIZATION : validateUser.headerName();
    HttpServletRequest request = ((ServletRequestAttributes) RequestContextHolder.currentRequestAttributes()).getRequest();

    logger.info("headerName = " + headerName);
    logger.info("request = " + request);
    String token = request.getHeader(headerName);
    logger.info("token = " + token);
    Boolean value = ptbUtils.validateJwtToken(token);
    System.out.println("value = " + value);
    return joinPoint.proceed();
}

从 

@Component
类中删除 
@interface
注释，并将其添加到 
@Aspect
类中。然后，将 @Around 注释修改为： 
@Around(value="@annotation(fully.qualified.package.here.ValidateUser)")
。我删除了 
execution(* *(..))
部分，因为该方面将涉及 every （公共）方法，这不是您想要的。

顺便说一句，我强烈建议使用 Spring Security 模块，而不是创建自定义方面来对用户进行身份验证和授权，并将自定义身份验证逻辑放入自定义 PermissionEvaluator 中。或者，假设您在代码片段中提到了 OAuth，请验证 Spring security OAuth2 设置是否足够。
