springboot拦截器中获取配置文件值

package com.zhx.web.interceptor;

import com.zhx.util.other.IpUtil;

import org.slf4j.Logger;

import org.slf4j.LoggerFactory;

import org.springframework.beans.factory.annotation.Value;

import org.springframework.web.servlet.HandlerInterceptor;

import org.springframework.web.servlet.ModelAndView;

import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpServletResponse;

public class LoginInterceptor implements HandlerInterceptor {

    private Logger log = LoggerFactory.getLogger(String.valueOf(LoginInterceptor.class));

    @Value("${spring.profiles.active}")//取配置文件的值

    private  String environment;

    @Override

    public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object o) throws Exception {

        String ip = IpUtil.getIpAddr(request);

        log.info("###################IP访问来自{}#################运行环境{}",ip,environment);

        if (ip.equals("####.##.##.##") || "dev".equals(environment)){

            return true;

        }

        return false;

    }

    @Override

    public void postHandle(HttpServletRequest request, HttpServletResponse response, Object o, ModelAndView modelAndView) throws Exception {

        if(response.getStatus()==500){

            modelAndView.setViewName("error");

        }else if(response.getStatus()==404){

            modelAndView.setViewName("404");

        }

    }

    @Override

    public void afterCompletion(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, Object o, Exception e) throws Exception {

    }

}

自定义拦截器：对指定ip进行限制

package com.zhx;

import com.zhx.config.ApiServerConfig;

import com.zhx.config.SmsConfig;

import com.zhx.web.interceptor.LoginInterceptor;

import org.springframework.boot.SpringApplication;

import org.springframework.boot.autoconfigure.SpringBootApplication;

import org.springframework.boot.context.embedded.ConfigurableEmbeddedServletContainer;

import org.springframework.boot.context.embedded.EmbeddedServletContainerCustomizer;

import org.springframework.boot.context.properties.EnableConfigurationProperties;

import org.springframework.context.annotation.Bean;

import org.springframework.transaction.annotation.EnableTransactionManagement;

import org.springframework.web.servlet.config.annotation.InterceptorRegistry;

import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;

@EnableTransactionManagement

@SpringBootApplication

@EnableConfigurationProperties({SmsConfig.class,ApiServerConfig.class})

public class Application extends WebMvcConfigurerAdapter {

    public static void main(String[] args) {

        SpringApplication.run(Application.class, args);

    }

    /**

     * 配置拦截器

     * @param registry

     */

    @Override

    public void addInterceptors(InterceptorRegistry registry) {

        /**

         * 加入ip验证拦截器

         */

        registry.addInterceptor(loginInterceptor()).addPathPatterns("/**");

        super.addInterceptors(registry);

    }

    @Bean

    public EmbeddedServletContainerCustomizer containerCustomizer(){

        return new EmbeddedServletContainerCustomizer() {

            @Override

            public void customize(ConfigurableEmbeddedServletContainer container) {

                container.setSessionTimeout(1800);

            }

        };

    }

    @Bean //将自定义拦截器注册到spring bean中

    public  LoginInterceptor loginInterceptor(){

        return new LoginInterceptor();

    }

}

这里注册拦截器时要以bean的方式注册进去，这样启动时拦截器才能取到配置文件的值。
