SpringWeb项目中实现自己的Interceptor

编写自己的拦截器

1、编写一个SecurityInterceptor拦截器

import org.assertj.core.annotations.Nullable;
import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.handler.HandlerInterceptorAdapter;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

public class SecurityInterceptor extends HandlerInterceptorAdapter {

    public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {
        System.out.println(">>>>>> SecurityInterceptor.preHandle");
        return true;
    }

    public void postHandle(HttpServletRequest request, HttpServletResponse response, Object handler,
        @Nullable ModelAndView modelAndView) throws Exception {
        System.out.println(">>>>>> SecurityInterceptor.postHandle");
    }

    public void afterCompletion(HttpServletRequest request, HttpServletResponse response, Object handler, @Nullable Exception ex)
        throws Exception {
        System.out.println(">>>>>> SecurityInterceptor.afterCompletion");
    }
}

1、编写一个RoleAuthorizationInterceptor拦截器

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.assertj.core.annotations.Nullable;
import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.handler.HandlerInterceptorAdapter;

public class RoleAuthorizationInterceptor extends HandlerInterceptorAdapter {

    public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {
        System.out.println(">>>>>> RoleAuthorizationInterceptor.preHandle");
        return true;
    }

    public void postHandle(HttpServletRequest request, HttpServletResponse response, Object handler, @Nullable ModelAndView modelAndView) throws Exception {
        System.out.println(">>>>>> RoleAuthorizationInterceptor.postHandle");
    }

    public void afterCompletion(HttpServletRequest request, HttpServletResponse response, Object handler, @Nullable Exception ex) throws Exception {
        System.out.println(">>>>>> RoleAuthorizationInterceptor.afterCompletion");
    }
}

注册拦截器

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.InterceptorRegistration;
import org.springframework.web.servlet.config.annotation.InterceptorRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurationSupport;

@Configuration
public class WebSecurityConfig extends WebMvcConfigurationSupport {

    @Bean
    public SecurityInterceptor getSecurityInterceptor() {
        return new SecurityInterceptor();
    }

    @Bean
    public RoleAuthorizationInterceptor getRoleAuthorizationInterceptor() {
        return new RoleAuthorizationInterceptor();
    }

    @Override
    public void addInterceptors(InterceptorRegistry registry) {
        InterceptorRegistration addInterceptor = registry.addInterceptor(getSecurityInterceptor());
        // 排除配置
        addInterceptor.excludePathPatterns("/"+ HttpStatus.FORBIDDEN.value());
        addInterceptor.excludePathPatterns("/toLogin");
        addInterceptor.excludePathPatterns("/login**");
        addInterceptor.excludePathPatterns("/register**");
        // 拦截配置
        addInterceptor.addPathPatterns("/**");

        InterceptorRegistration roleInter = registry.addInterceptor(getRoleAuthorizationInterceptor());
        // 拦截配置
        roleInter.addPathPatterns("/**");
    }
}
