从 jersey 迁移到 spring-mvc/rest：ContainerRequestFilter、ContainerResponseFilter

由于业务需求，我需要从 jersey 迁移到 spring-mvc/rest ...

我正在 spring-mvc 中搜索相当于 jersey 的东西ContainerRequestFilter, ContainerResponseFilter.

有任何想法吗？

我想你正在寻找的是HandlerInterceptor http://docs.spring.io/spring/docs/current/javadoc-api/org/springframework/web/servlet/HandlerInterceptor.html。您不会在双类请求/响应风格中找到它，但是两个过滤器方法都包含在同一个类中，形式为preHandle and postHandle，这相当于请求 -filter和回应-filter， 分别。拦截器包装处理程序调用。这是一个例子：

拦截器：

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.web.servlet.HandlerInterceptor;
import org.springframework.web.servlet.ModelAndView;

public class LogginHandlerInterceptor implements HandlerInterceptor{
    @Override
    public boolean preHandle(HttpServletRequest hsr, 
                             HttpServletResponse hsr1, Object handler) throws Exception {
        System.out.println("preHandle - " + handler);
        return true;
    }

    @Override
    public void postHandle(HttpServletRequest hsr, HttpServletResponse hsr1, 
                           Object handler, ModelAndView mav) throws Exception {
        System.out.println("postHandle - " + handler);
    }

    @Override
    public void afterCompletion(HttpServletRequest hsr, HttpServletResponse hsr1, 
                                Object handler, Exception excptn) throws Exception {
        System.out.println("afterCompletion - " + handler);
    }
}

Config:

import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
import org.springframework.web.servlet.config.annotation.InterceptorRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;

@Configuration
@EnableWebMvc
@ComponentScan(basePackages = {"..."})
public class WebAppConfiguration extends WebMvcConfigurerAdapter {
    ...
    @Override
    public void addInterceptors(InterceptorRegistry registry) {
        registry.addInterceptor(new LogginHandlerInterceptor());
    }
    ...
}

也可以看看：

• 使用HandlerInterceptor拦截请求 http://docs.spring.io/spring/docs/current/spring-framework-reference/htmlsingle/#mvc-handlermapping-interceptor
• MVC 配置拦截器 http://docs.spring.io/spring/docs/current/spring-framework-reference/htmlsingle/#mvc-config-interceptors
