将Spring HandlerInterceptor仅绑定到一个控制器

// CustomInterceptor.java
public class CustomInterceptor implements HandlerInterceptor {
    @Override
    public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {
        // 在请求处理前进行拦截处理
        return true;
    }

    @Override
    public void postHandle(HttpServletRequest request, HttpServletResponse response, Object handler, ModelAndView modelAndView) throws Exception {
        // 在请求处理后进行拦截处理
    }

    @Override
    public void afterCompletion(HttpServletRequest request, HttpServletResponse response, Object handler, Exception ex) throws Exception {
        // 在视图渲染之前进行拦截处理
    }
}

// Controller.java
@Controller
@RequestMapping("/example")
@Interceptor(CustomInterceptor.class)
public class Controller {
    @RequestMapping("/endpoint")
    public String handleRequest() {
        // 控制器处理请求的逻辑
        return "view";
    }
}

<!-- spring-config.xml -->

    <mvc:interceptor>
        <mvc:mapping path="/example/**"/>
        <bean class="com.example.CustomInterceptor"/>
