spring boot 中使用 Redis 与 Log

spring boot + mybatis + redis 配置

2. RedisConfig 配置

package com.springboot.config;

import org.springframework.cache.CacheManager;
import org.springframework.cache.annotation.CachingConfigurerSupport;
import org.springframework.cache.interceptor.KeyGenerator;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.redis.cache.RedisCacheManager;
import org.springframework.data.redis.connection.RedisConnectionFactory;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.data.redis.core.StringRedisTemplate;
import org.springframework.data.redis.serializer.Jackson2JsonRedisSerializer;

import com.fasterxml.jackson.annotation.JsonAutoDetect;
import com.fasterxml.jackson.annotation.PropertyAccessor;
import com.fasterxml.jackson.databind.ObjectMapper;

@Configuration
public class RedisConfig extends CachingConfigurerSupport {

    // 自定义缓存key生成策略
    @Bean
    public KeyGenerator keyGenerator() {
        return new KeyGenerator() {
            @Override
            public Object generate(Object target, java.lang.reflect.Method method, Object... params) {
                StringBuffer sb = new StringBuffer();
                sb.append(target.getClass().getName());
                sb.append(method.getName());
                for (Object obj : params) {
                    sb.append(obj.toString());
                }
                return sb.toString();
            }
        };
    }

    // 缓存管理器
    @Bean
    public CacheManager cacheManager(@SuppressWarnings("rawtypes") RedisTemplate redisTemplate) {
        RedisCacheManager cacheManager = new RedisCacheManager(redisTemplate);
        // 设置缓存过期时间
        cacheManager.setDefaultExpiration(10000);
        return cacheManager;
    }

    @Bean
    public RedisTemplate<String, String> redisTemplate(RedisConnectionFactory factory) {
        StringRedisTemplate template = new StringRedisTemplate(factory);
        setSerializer(template);// 设置序列化工具
        template.afterPropertiesSet();
        return template;
    }

    private void setSerializer(StringRedisTemplate template) {
        @SuppressWarnings({ "rawtypes", "unchecked" })
        Jackson2JsonRedisSerializer jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer(Object.class);
        ObjectMapper om = new ObjectMapper();
        om.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);
        om.enableDefaultTyping(ObjectMapper.DefaultTyping.NON_FINAL);
        jackson2JsonRedisSerializer.setObjectMapper(om);
        template.setValueSerializer(jackson2JsonRedisSerializer);
    }
}

spring boot + Log

1.LogAspect 配置

package com.springboot.aspect;

import java.lang.reflect.Method;
import java.util.Date;
import javax.servlet.http.HttpServletRequest;
import org.aspectj.lang.ProceedingJoinPoint;
import org.aspectj.lang.annotation.Around;
import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Pointcut;
import org.aspectj.lang.reflect.MethodSignature;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.core.LocalVariableTableParameterNameDiscoverer;
import org.springframework.stereotype.Component;
import com.springboot.annotation.Log;
import com.springboot.dao.SysLogDao;
import com.springboot.domain.SysLog;
import com.springboot.util.HttpContextUtils;
import com.springboot.util.IPUtils;

@Aspect
@Component
public class LogAspect {

    @Autowired
    private SysLogDao sysLogDao;

    @Pointcut("@annotation(com.springboot.annotation.Log)")
    public void pointcut() {
    }

    @Around("pointcut()")
    public void around(ProceedingJoinPoint point) {
        long beginTime = System.currentTimeMillis();
        try {
            // 执行方法
            point.proceed();
        } catch (Throwable e) {
            e.printStackTrace();
        }
        // 执行时长(毫秒)
        long time = System.currentTimeMillis() - beginTime;
        // 保存日志
        saveLog(point, time);
    }

    private void saveLog(ProceedingJoinPoint joinPoint, long time) {
        MethodSignature signature = (MethodSignature) joinPoint.getSignature();
        Method method = signature.getMethod();
        SysLog sysLog = new SysLog();
        Log logAnnotation = method.getAnnotation(Log.class);
        if (logAnnotation != null) {
            // 注解上的描述
            sysLog.setOperation(logAnnotation.value());
        }
        // 请求的方法名
        String className = joinPoint.getTarget().getClass().getName();
        String methodName = signature.getName();
        sysLog.setMethod(className + "." + methodName + "()");
        // 请求的方法参数值
        Object[] args = joinPoint.getArgs();
        // 请求的方法参数名称
        LocalVariableTableParameterNameDiscoverer u = new LocalVariableTableParameterNameDiscoverer();
        String[] paramNames = u.getParameterNames(method);
        if (args != null && paramNames != null) {
            String params = "";
            for (int i = 0; i < args.length; i++) {
                params += "  " + paramNames[i] + ": " + args[i];
            }
            sysLog.setParams(params);
        }
        // 获取request
        HttpServletRequest request = HttpContextUtils.getHttpServletRequest();
        // 设置IP地址
        sysLog.setIp(IPUtils.getIpAddr(request));
        // 模拟一个用户名
        sysLog.setUsername("mrbird");
        sysLog.setTime((int) time);
        Date date = new Date();
        sysLog.setCreateTime(date);
        // 保存系统日志
        sysLogDao.saveSysLog(sysLog);
    }
}

2.日志工具类 IPUtils 获取 IP

package com.springboot.util;

import javax.servlet.http.HttpServletRequest;

public class IPUtils {

    /**
     * 获取IP地址
     * 
     * 使用Nginx等反向代理软件， 则不能通过request.getRemoteAddr()获取IP地址
     * 如果使用了多级反向代理的话，X-Forwarded-For的值并不止一个，而是一串IP地址，X-Forwarded-For中第一个非unknown的有效IP字符串，则为真实IP地址
     */
    public static String getIpAddr(HttpServletRequest request) {

        String ip = request.getHeader("x-forwarded-for");
        if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {
            ip = request.getHeader("Proxy-Client-IP");
        }
        if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {
            ip = request.getHeader("WL-Proxy-Client-IP");
        }
        if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {
            ip = request.getRemoteAddr();
        }
        return "0:0:0:0:0:0:0:1".equals(ip) ? "127.0.0.1" : ip;
    }

}

3.工具类 HttpContextUtils

package com.springboot.util;

import javax.servlet.http.HttpServletRequest;
import org.springframework.web.context.request.RequestContextHolder;
import org.springframework.web.context.request.ServletRequestAttributes;

public class HttpContextUtils {
    public static HttpServletRequest getHttpServletRequest() {
        return ((ServletRequestAttributes) RequestContextHolder.getRequestAttributes()).getRequest();
    }
}
