Spring Boot + Mybatis + Redis二級快取例項

xiaolyuh123發表於2017-06-29

二級快取是多個SqlSession共享的，其作用域是mapper的同一個namespace，不同的sqlSession兩次執行相同namespace下的sql語句且向sql中傳遞引數也相同即最終執行相同的sql語句，第一次執行完畢會將資料庫中查詢的資料寫到快取（記憶體），第二次會從快取中獲取資料將不再從資料庫查詢，從而提高查詢效率。Mybatis預設沒有開啟二級快取需要在setting全域性引數中配置開啟二級快取。

下面是使用Redis來作為Mybatis二級快取的例項：

Redis的安裝使用的是Docker，Docker的簡介

application.properties

在application.properties檔案中配置Redis，Mybatis，開啟Mybatis二級快取等：

server.port=80
# 資料來源配置
spring.datasource.url=jdbc:mysql://localhost:3306/ssb_test
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.datasource.username=root
spring.datasource.password=root
#連線池配置
#spring.datasource.type=org.apache.commons.dbcp2.BasicDataSource

#mybatis
#entity掃描的包名
mybatis.type-aliases-package=com.xiaolyuh.domain.model
#Mapper.xml所在的位置

#開啟MyBatis的二級快取
mybatis.configuration.cache-enabled=true

#pagehelper

Redis配置類替換序列化實現方式

package com.xiaolyuh.config;

import com.fasterxml.jackson.annotation.JsonAutoDetect;
import com.fasterxml.jackson.annotation.PropertyAccessor;
import com.fasterxml.jackson.databind.ObjectMapper;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.redis.connection.RedisConnectionFactory;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.data.redis.serializer.Jackson2JsonRedisSerializer;
import org.springframework.data.redis.serializer.StringRedisSerializer;

@Configuration
public class RedisConfig {

	/**
	 * 重寫Redis序列化方式，使用Json方式:
	 * 當我們的資料儲存到Redis的時候，我們的鍵（key）和值（value）都是通過Spring提供的Serializer序列化到資料庫的。RedisTemplate預設使用的是JdkSerializationRedisSerializer，StringRedisTemplate預設使用的是StringRedisSerializer。
	 * Spring Data JPA為我們提供了下面的Serializer：
	 * GenericToStringSerializer、Jackson2JsonRedisSerializer、JacksonJsonRedisSerializer、JdkSerializationRedisSerializer、OxmSerializer、StringRedisSerializer。
	 * 在此我們將自己配置RedisTemplate並定義Serializer。
	 * @param redisConnectionFactory
	 * @return
	 */
	@Bean
	public RedisTemplate<String, Object> redisTemplate(RedisConnectionFactory redisConnectionFactory) {
		RedisTemplate<String, Object> redisTemplate = new RedisTemplate<>();
		redisTemplate.setConnectionFactory(redisConnectionFactory);

		Jackson2JsonRedisSerializer<Object> jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer<Object>(Object.class);
		ObjectMapper om = new ObjectMapper();
        om.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);
        om.enableDefaultTyping(ObjectMapper.DefaultTyping.NON_FINAL);  
        jackson2JsonRedisSerializer.setObjectMapper(om);

		// 設定值（value）的序列化採用Jackson2JsonRedisSerializer。
		redisTemplate.setValueSerializer(jackson2JsonRedisSerializer);
		// 設定鍵（key）的序列化採用StringRedisSerializer。
		redisTemplate.setKeySerializer(new StringRedisSerializer());

		redisTemplate.afterPropertiesSet();
		return redisTemplate;
	}
}

Spring容器獲取Bean工具類

通過Spring Aware（容器感知）來獲取到ApplicationContext，然後根據ApplicationContext獲取容器中的Bean。

package com.xiaolyuh.holder;

import org.springframework.context.ApplicationContext;
import org.springframework.context.ApplicationContextAware;
import org.springframework.stereotype.Component;

/**
 * 以靜態變數儲存Spring ApplicationContext, 可在任何程式碼任何地方任何時候中取出ApplicaitonContext.
 */
@Component
public class SpringContextHolder implements ApplicationContextAware {
    private static ApplicationContext applicationContext;

    /**
     * 實現ApplicationContextAware介面的context注入函式, 將其存入靜態變數.
     */
    public void setApplicationContext(ApplicationContext applicationContext) {
        SpringContextHolder.applicationContext = applicationContext; // NOSONAR
    }

    /**
     * 取得儲存在靜態變數中的ApplicationContext.
     */
    public static ApplicationContext getApplicationContext() {
        checkApplicationContext();
        return applicationContext;
    }

    /**
     * 從靜態變數ApplicationContext中取得Bean, 自動轉型為所賦值物件的型別.
     */
    @SuppressWarnings("unchecked")
    public static <T> T getBean(String name) {
        checkApplicationContext();
        return (T) applicationContext.getBean(name);
    }

    /**
     * 從靜態變數ApplicationContext中取得Bean, 自動轉型為所賦值物件的型別.
     */
    @SuppressWarnings("unchecked")
    public static <T> T getBean(Class<T> clazz) {
        checkApplicationContext();
        return (T) applicationContext.getBeansOfType(clazz);
    }

    /**
     * 清除applicationContext靜態變數.
     */
    public static void cleanApplicationContext() {
        applicationContext = null;
    }

    private static void checkApplicationContext() {
        if (applicationContext == null) {
            throw new IllegalStateException("applicaitonContext未注入,請在applicationContext.xml中定義SpringContextHolder");
        }
    }
}

自定的Mybatis快取

自定義快取需要實現Mybatis的Cache介面，我這裡將使用Redis來作為快取的容器。

package com.xiaolyuh.cache;

import com.xiaolyuh.holder.SpringContextHolder;
import org.apache.ibatis.cache.Cache;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.dao.DataAccessException;
import org.springframework.data.redis.connection.RedisConnection;
import org.springframework.data.redis.core.RedisCallback;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.util.CollectionUtils;

import java.util.Collections;
import java.util.Set;
import java.util.concurrent.TimeUnit;
import java.util.concurrent.locks.ReadWriteLock;
import java.util.concurrent.locks.ReentrantReadWriteLock;

/**
 * 使用Redis來做Mybatis的二級快取
 * 實現Mybatis的Cache介面
 */
public class MybatisRedisCache implements Cache {

    private static final Logger logger = LoggerFactory.getLogger(MybatisRedisCache.class);

    // 讀寫鎖
    private final ReadWriteLock readWriteLock = new ReentrantReadWriteLock(true);

    private RedisTemplate<String, Object> redisTemplate = SpringContextHolder.getBean("redisTemplate");

    private String id;

    public MybatisRedisCache(final String id) {
        if (id == null) {
            throw new IllegalArgumentException("Cache instances require an ID");
        }
        logger.info("Redis Cache id " + id);
        this.id = id;
    }

    @Override
    public String getId() {
        return this.id;
    }

    @Override
    public void putObject(Object key, Object value) {
        if (value != null) {
            // 向Redis中新增資料，有效時間是2天
            redisTemplate.opsForValue().set(key.toString(), value, 2, TimeUnit.DAYS);
        }
    }

    @Override
    public Object getObject(Object key) {
        try {
            if (key != null) {
                Object obj = redisTemplate.opsForValue().get(key.toString());
                return obj;
            }
        } catch (Exception e) {
            logger.error("redis ");
        }
        return null;
    }

    @Override
    public Object removeObject(Object key) {
        try {
            if (key != null) {
                redisTemplate.delete(key.toString());
            }
        } catch (Exception e) {
        }
        return null;
    }

    @Override
    public void clear() {
        logger.debug("清空快取");
        try {
            Set<String> keys = redisTemplate.keys("*:" + this.id + "*");
            if (!CollectionUtils.isEmpty(keys)) {
                redisTemplate.delete(keys);
            }
        } catch (Exception e) {
        }
    }

    @Override
    public int getSize() {
        Long size = (Long) redisTemplate.execute(new RedisCallback<Long>() {
            @Override
            public Long doInRedis(RedisConnection connection) throws DataAccessException {
                return connection.dbSize();
            }
        });
        return size.intValue();
    }

    @Override
    public ReadWriteLock getReadWriteLock() {
        return this.readWriteLock;
    }
}
