JAVA过滤器和拦截器有什么区别详细讲解

import javax.servlet.Filter;
import javax.servlet.FilterChain;
import javax.servlet.FilterConfig;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
import java.io.IOException;

public class MyFilter implements Filter {
    @Override
    public void init(FilterConfig filterConfig) throws ServletException {
        // 初始化过滤器
    }

    @Override
    public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain)
            throws IOException, ServletException {
        // 在请求处理之前执行的代码
        System.out.println("Before request processing");

        // 传递请求到下一个过滤器或目标资源
        chain.doFilter(request, response);

        // 在响应返回之前执行的代码
        System.out.println("After response processing");
    }

    @Override
    public void destroy() {
        // 销毁过滤器
    }
}

import org.springframework.web.servlet.HandlerInterceptor;
import org.springframework.web.servlet.ModelAndView;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

public class MyInterceptor implements HandlerInterceptor {
    @Override
    public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler)
            throws Exception {
        // 在请求处理之前执行的代码
        System.out.println("Before request processing");
        return true; // 返回true表示继续处理请求，返回false表示中断请求处理
    }

    @Override
    public void postHandle(HttpServletRequest request, HttpServletResponse response, Object handler,
                           ModelAndView modelAndView) throws Exception {
        // 在控制器处理请求之后，但在视图渲染之前执行的代码
        System.out.println("After request processing, before view rendering");
    }

    @Override
    public void afterCompletion(HttpServletRequest request, HttpServletResponse response, Object handler,
                                Exception ex) throws Exception {
        // 在视图渲染之后执行的代码
        System.out.println("After view rendering");
    }
}
