Spring Boot 拦截器权限验证 HandlerInterceptor 配置类

关键词由优快云通过智能技术生成

集成拦截器

一.引入依赖

		<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>

二.编写配置类

/*
 * InterceptorRegistry内的addInterceptor需要一个实现HandlerInterceptor接口的拦截器实例，
 * addPathPatterns方法用于设置拦截器的过滤路径规则。
 * 在配置类上添加了注解@Configuration，标明了该类是一个配置类并且会将该类作为一个SpringBean添加到IOC容器内
 */
@Configuration
public class InterceptorConfig implements WebMvcConfigurer {
    @Override
    public void addInterceptors(InterceptorRegistry registry) {
        //拦截所有请求
        registry.addInterceptor(authenticationInterceptor())
                .addPathPatterns("/**");
    }
    @Bean
    public AuthenticationInterceptor authenticationInterceptor(){
        return new AuthenticationInterceptor();
    }
}

三.编写拦截方法

public class AuthenticationInterceptor implements HandlerInterceptor {

    @Override
    public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {
        //TODO 拦截器过滤请求的方法
        return true;
    }

    @Override
    public void postHandle(HttpServletRequest request, HttpServletResponse response, Object handler, ModelAndView modelAndView) throws Exception {
    }

    @Override
    public void afterCompletion(HttpServletRequest request, HttpServletResponse response, Object handler, Exception ex) throws Exception {
    }
}
