生成一段springboot项目中的拦截器代码

好的,以下是一段简单的Spring Boot拦截器示例代码:
```java
@Component
public class CustomInterceptor implements HandlerInterceptor {
@Override
public void afterCompletion(HttpServletRequest request, HttpServletResponse response, Object handler, Exception ex)
throws Exception {
// This method is called after the handler is executed and after the view is rendered
}
@Override
public void postHandle(HttpServletRequest request, HttpServletResponse response, Object handler,
ModelAndView modelAndView) throws Exception {
// This method is called after the handler is executed, but before the view is rendered
}
@Override
public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler)
throws Exception {
// This method is called before the handler is executed. Here, we can perform web request logging or validation
return true; // If we return false from here, the request will be rejected
}
}
```
这是一个名为 CustomInterceptor 的自定义拦截器,在 preHandle() 方法中进行了请求的前置处理,postHandle() 和 afterCompletion() 方法分别用于处理请求完成后的操作。同时,我们还需要将该拦截器注册到 Spring Boot 应用中,方法如下:
```java
@Configuration
public class AppConfig implements WebMvcConfigurer {
@Autowired
private CustomInterceptor customInterceptor;
@Override
public void addInterceptors(InterceptorRegistry registry) {
registry.addInterceptor(customInterceptor);
}
}
```
这样就可以将 CustomInterceptor 注册进入 Spring Boot 应用中,并对指定的请求进行拦截处理了。
