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

Question

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

我正在 spring-mvc 中搜索与球衣的 ContainerRequestFilter、ContainerResponseFilter 等效的东西。

有什么想法吗？

我认为您正在寻找的是HandlerInterceptor。你不会在二类请求/响应风格中找到它，但两种过滤方法都包含在同一个类中，形式为preHandle和postHandle，相当于request-filter和分别响应-filter。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);
    }
}

配置：

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());
    }
    ...
}
