springboot+AOP接口签名鉴权

Spring Boot结合AOP(面向切面编程)可以方便地实现接口签名级别的权限验证。首先,你需要创建一个自定义的注解,比如`@ApiPermission`,用于标记那些需要特定权限的接口。然后,利用AOP的通知(Advice)功能,编写一个前置通知(Before advice),该通知会在目标方法执行前检查是否具备所需的权限。
下面是一个简单的步骤说明:
1. **创建注解**:
```java
@Retention(RetentionPolicy.RUNTIME)
@Target(ElementType.METHOD)
public @interface ApiPermission {
String[] roles() default {};
}
```
2. **配置全局拦截器**:
```java
@Configuration
@EnableAspectJAutoProxy
public class AopConfig {
@Autowired
private SecurityContext securityContext;
@Pointcut("@annotation(apiPermission)")
public void apiPermissionMethods(ApiPermission apiPermission) {
// 点匹配规则
}
@Before("apiPermissionMethods()")
public Object checkPermission(JoinPoint joinPoint, ApiPermission apiPermission) throws Throwable {
String[] requiredRoles = apiPermission.roles();
Authentication authentication = securityContext.getAuthentication();
if (requiredRoles != null && !Arrays.asList(requiredRoles).contains(authentication.getName())) {
throw new PermissionDeniedException("无权限访问");
}
return proceed(joinPoint);
}
}
```
3. **在接口上应用权限注解**:
```java
@Service
@ApiPermission(roles = {"ADMIN"})
public interface UserService {
void createUser(User user);
}
```
当试图调用未授权的接口时,将会抛出`PermissionDeniedException`异常。
