springmvc-redis-mybatis

springmvc redis mybatis springboot 集成demo.

• redis提供缓存
• mybatis提供ORM框架 在8G内存机器下，QPS性能轻松达到2K.

redis依赖

		<dependency>
			<groupId>org.springframework.data</groupId>
			<artifactId>spring-data-redis</artifactId>
		</dependency>

		<dependency>
			<groupId>redis.clients</groupId>
			<artifactId>jedis</artifactId>
		</dependency>

springboot版本

	<parent>
		<groupId>org.springframework.boot</groupId>
		<artifactId>spring-boot-starter-parent</artifactId>
		<version>1.2.2.RELEASE</version>
	</parent>

缓存配置说明

  @Bean
  public JedisConnectionFactory redisConnectionFactory() {
    JedisConnectionFactory redisConnectionFactory = new JedisConnectionFactory();

    // Defaults
    redisConnectionFactory.setHostName("127.0.0.1");
    redisConnectionFactory.setPort(6379);
    return redisConnectionFactory;
  }

  @Bean
  public RedisTemplate<String, String> redisTemplate(RedisConnectionFactory cf) {
    RedisTemplate<String, String> redisTemplate = new RedisTemplate<String, String>();
    redisTemplate.setConnectionFactory(cf);
    return redisTemplate;
  }

  @Bean
  public CacheManager cacheManager(RedisTemplate<String, String> redisTemplate) {
    RedisCacheManager cacheManager = new RedisCacheManager(redisTemplate);

    cacheManager.setDefaultExpiration(300); // 设置失效时间
    return cacheManager;
  }

注意事项

MODEL或者entity实体类需要实现序列化接口。

public class User implements Serializable{
        
        // 这句话不能少的。否则运行期间会报错。
	private static final long serialVersionUID = -9078118632986764352L;

	private int user_id;
	private int user_type;

	public int getUser_id() {
		return user_id;
	}
	public void setUser_id(int user_id) {
		this.user_id = user_id;
	}
	public int getUser_type() {
		return user_type;
	}
	public void setUser_type(int user_type) {
		this.user_type = user_type;
	}
	
}
