SpringMVC配置太多？试试SpringBoot

4.Redis数据源设备.

import org.springframework.beans.factory.annotation.Autowired;import org.springframework.beans.factory.annotation.Qualifier;import org.springframework.beans.factory.annotation.Value;import org.springframework.context.annotation.Bean;import org.springframework.context.annotation.Configuration;import redis.clients.jedis.JedisPool;import redis.clients.jedis.JedisPoolConfig;/** * 设备redis数据源 * * @ClassName RedisConfig * @author Zhang.Tao * @Date 2017年4月24日 下昼5:25:30 * @version V2.0.0 */@Configurationpublic class RedisConfig {             @Bean(name= "jedis.pool")   @Autowired   public JedisPool jedisPool(@Qualifier("jedis.pool.config") JedisPoolConfig config,                @Value("${jedis.pool.host}")String host,                @Value("${jedis.pool.port}")int port) {       return new JedisPool(config, host, port);   }        @Bean(name= "jedis.pool.config")   public JedisPoolConfig jedisPoolConfig (@Value("${jedis.pool.config.maxTotal}")int maxTotal,                               @Value("${jedis.pool.config.maxIdle}")int maxIdle,                               @Value("${jedis.pool.config.maxWaitMillis}")int maxWaitMillis) {       JedisPoolConfig config = new JedisPoolConfig();       config.setMaxTotal(maxTotal);       config.setMaxIdle(maxIdle);       config.setMaxWaitMillis(maxWaitMillis);       return config;   }}

5.mybatis设备

6.MyBatis设备文件（这个和Spring没紧要，是mybatis的，必须写没缺点啊，老铁）

<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN" "http://mybatis.org/dtd/mybatis-3-config.dtd"><configuration> <properties> <property name="dialect" value=http://news.51cto.com/art/201710/"mysql" />
