spring boot 自学笔记(三) Redis集成—RedisTemplate

Spring boot 基于Spring,  Redis集成与Spring大同小异。

文章示例代码均以前篇笔记为基础增加修改，直接上代码：

pom.xml  Redis相关依赖：

 

	4.0.0
	com.vic
	vic
	0.1.0

	
		1.7
	
	
	
		org.springframework.boot
		spring-boot-starter-parent
		1.3.8.RELEASE
	

	
		
		
			org.springframework.boot
			spring-boot-starter-web
		
		
		
		
			org.springframework.boot
			spring-boot-starter-jdbc
		

		
			org.mybatis
			mybatis-spring
			1.2.2
		
		
			org.mybatis
			mybatis
			3.2.8

			com.mchange
			c3p0

            com.google.code.gson  
            gson  
          
		
		
	
	
		
			
				org.springframework.boot
				spring-boot-maven-plugin
			
		
	

 

 

application.properties增加redis相关属性：

 

 

#datasource
spring.datasource.jdbcUrl=jdbc:mysql://115.28.92.178:3306/wms?useUnicode\=true&characterEncoding\=utf8;autoReconnect\=true;maxReconnects\=10;connectTimeout\=180000;socketTimeout\=180000
spring.datasource.user=root
spring.datasource.password=xx
spring.datasource.driverClass=com.mysql.jdbc.Driver
spring.datasource.maxActive=100
spring.datasource.initialPoolSize=5
spring.datasource.minPoolSize=5
spring.datasource.maxPoolSize=20
spring.datasource.maxStatements=100
spring.datasource.maxIdleTime=3600
spring.datasource.acquireIncrement=2
spring.datasource.acquireRetryAttempts=10
spring.datasource.acquireRetryDelay=600
spring.datasource.testConnectionOnCheckin=true
spring.datasource.idleConnectionTestPeriod=1200
spring.datasource.checkoutTimeout=100000


#redis
spring.redis.hostName=115.28.92.178
spring.redis.port=6379  
spring.redis.password=xxx
spring.redis.pool.maxActive=8  
spring.redis.pool.maxWait=-1  
spring.redis.pool.maxIdle=8  
spring.redis.pool.minIdle=0  
spring.redis.timeout=0

 

 

com.vic.config包中新增RedisConfig.java:

 

 

/**
 * 
 * @author vic
 * @desc redis config bean
 *
 */
@Configuration
@EnableAutoConfiguration
public class RedisConfig {

	private static Logger logger = Logger.getLogger(RedisConfig.class);
	
	@Bean
	@ConfigurationProperties(prefix="spring.redis")
	public JedisPoolConfig getRedisConfig(){
		JedisPoolConfig config = new JedisPoolConfig();
		return config;
	}
	
	@Bean
	@ConfigurationProperties(prefix="spring.redis")
	public JedisConnectionFactory getConnectionFactory(){
		JedisConnectionFactory factory = new JedisConnectionFactory();
		JedisPoolConfig config = getRedisConfig();
		factory.setPoolConfig(config);
		logger.info("JedisConnectionFactory bean init success.");
		return factory;
	}
	
	
	@Bean
	public RedisTemplate getRedisTemplate(){
		RedisTemplate template = new StringRedisTemplate(getConnectionFactory());
		return template;
	}
}

 

 

 

 

 

OK,此时Reddis已经集成完成，下面来对常用操作做一些封装测试：

新增IRedisService接口定义一些常用操作接口，以及添加实现类RedisServiceImpl，代码如下：

 

IRedisService.java

 

/**
 * 
 * @author vic
 * @desc redis service
 */
public interface IRedisService {
	
	public boolean set(String key, String value);
	
	public String get(String key);
	
	public boolean expire(String key,long expire);
	
	public  boolean setList(String key ,List list);
	
	public  List getList(String key,Class clz);
	
	public long lpush(String key,Object obj);
	
	public long rpush(String key,Object obj);
	
	public String lpop(String key);
	
}

RedisServiceImpl.java

 

 

/**
 * 
 * @author vic
 * @desc resdis service
 *
 */
@Service
public class RedisServiceImpl implements IRedisService{

	@Autowired
	private RedisTemplate redisTemplate;
	
	@Override
	public boolean set(final String key, final String value) {
		boolean result = redisTemplate.execute(new RedisCallback() {
            @Override
            public Boolean doInRedis(RedisConnection connection) throws DataAccessException {
            	RedisSerializer serializer = redisTemplate.getStringSerializer();
                connection.set(serializer.serialize(key), serializer.serialize(value));
                return true;
            }
	    });
		return result;
	}

	public String get(final String key){
		String result = redisTemplate.execute(new RedisCallback() {
            @Override
            public String doInRedis(RedisConnection connection) throws DataAccessException {
            	RedisSerializer serializer = redisTemplate.getStringSerializer();
                byte[] value =  connection.get(serializer.serialize(key));
                return serializer.deserialize(value);
            }
	    });
		return result;
	}

	@Override
	public boolean expire(final String key, long expire) {
		return redisTemplate.expire(key, expire, TimeUnit.SECONDS);
	}

	@Override
	public  boolean setList(String key, List list) {
		String value = JSONUtil.toJson(list);
		return set(key,value);
	}

	@Override
	public  List getList(String key,Class clz) {
		String json = get(key);
		if(json!=null){
			List list = JSONUtil.toList(json, clz);
			return list;
		}
		return null;
	}

	@Override
	public long lpush(final String key, Object obj) {
		final String value = JSONUtil.toJson(obj);
		long result = redisTemplate.execute(new RedisCallback() {
            @Override
            public Long doInRedis(RedisConnection connection) throws DataAccessException {
            	RedisSerializer serializer = redisTemplate.getStringSerializer();
                long count = connection.lPush(serializer.serialize(key), serializer.serialize(value));
                return count;
            }
	    });
		return result;
	}

	@Override
	public long rpush(final String key, Object obj) {
		final String value = JSONUtil.toJson(obj);
		long result = redisTemplate.execute(new RedisCallback() {
            @Override
            public Long doInRedis(RedisConnection connection) throws DataAccessException {
            	RedisSerializer serializer = redisTemplate.getStringSerializer();
                long count = connection.rPush(serializer.serialize(key), serializer.serialize(value));
                return count;
            }
	    });
		return result;
	}

	@Override
	public String lpop(final String key) {
		String result = redisTemplate.execute(new RedisCallback() {
            @Override
            public String doInRedis(RedisConnection connection) throws DataAccessException {
            	RedisSerializer serializer = redisTemplate.getStringSerializer();
                byte[] res =  connection.lPop(serializer.serialize(key));
                return serializer.deserialize(res);
            }
	    });
		return result;
	}

}

其中的JSONUtil类，可下载demo代码查看，其实就是一个JSON的工具类。

 

 

在ExampleController中添加测试方法：

 

@RestController
public class ExampleController {

	@Autowired
	private IUserService userService;
	
	@Autowired
	private IRedisService redisService;
	
	@RequestMapping("/users")
	public ResponseModal users(){
		List users = userService.getAll();
		ResponseModal modal = new ResponseModal(200,true,"",users);
		return modal;
	}
	
	@RequestMapping("/redis/set")
	public ResponseModal redisSet(@RequestParam("value")String value){
		boolean isOk = redisService.set("name", value);
		return new ResponseModal(isOk ? 200 : 500, isOk, isOk ? "success" : "error" , null);
	}
	
	@RequestMapping("/redis/get")
	public ResponseModal redisGet(){
		String name = redisService.get("name");
		return new ResponseModal(200, true,"success",name);
	}
	
}

 

 

 

 

 

运行Application的main函数

浏览器输入：http://localhost:8080/redis/set?value=vic  响应结果：

 

{"code":200,"success":true,"message":"success","response":null}

 

浏览器输入：http://localhost:8080/redis/get  响应结果：

 

{"code":200,"success":true,"message":"success","response":"vic"}
