SpringBoot整合SpringDataRedis的示例代码

  本文介绍下SpringBoot如何整合SpringDataRedis框架的，SpringDataRedis具体的内容在前面已经介绍过了，可自行参考。

  创建SpringBoot项目，并添加如下依赖:

<dependencies> <!-- springBoot 的启动器 --> <dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId> </dependency> <!-- Spring Data Redis 的启动器 --> <dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-data-redis</artifactId> </dependency> <dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-test</artifactId><scope>test</scope> </dependency> <dependency><groupId>redis.clients</groupId><artifactId>jedis</artifactId><version>2.9.0</version> </dependency></dependencies>2.设置application.properties文件

spring.redis.jedis.pool.max-idle=10spring.redis.jedis.pool.min-idle=5spring.redis.pool.max-total=20spring.redis.hostName=192.168.88.120spring.redis.port=63793.添加Redis的配置类

  添加Redis的java配置类，设置相关的信息。

/** * @program: springboot-redis-demo * @description: Redis的配置类 * @author: 波波烤鸭 * @create: 2019-05-20 23:40 */@Configurationpublic class RedisConfig { /** * 1.创建JedisPoolConfig对象。在该对象中完成一些链接池配置 * @ConfigurationProperties:会将前缀相同的内容创建一个实体。 */ @Bean @ConfigurationProperties(prefix='spring.redis.pool') public JedisPoolConfig jedisPoolConfig(){JedisPoolConfig config = new JedisPoolConfig();/*//最大空闲数config.setMaxIdle(10);//最小空闲数config.setMinIdle(5);//最大链接数config.setMaxTotal(20);*/System.out.println('默认值：'+config.getMaxIdle());System.out.println('默认值：'+config.getMinIdle());System.out.println('默认值：'+config.getMaxTotal());return config; } /** * 2.创建JedisConnectionFactory：配置redis链接信息 */ @Bean @ConfigurationProperties(prefix='spring.redis') public JedisConnectionFactory jedisConnectionFactory(JedisPoolConfig config){System.out.println('配置完毕：'+config.getMaxIdle());System.out.println('配置完毕：'+config.getMinIdle());System.out.println('配置完毕：'+config.getMaxTotal());JedisConnectionFactory factory = new JedisConnectionFactory();//关联链接池的配置对象factory.setPoolConfig(config);//配置链接Redis的信息//主机地址/*factory.setHostName('192.168.70.128');//端口factory.setPort(6379);*/return factory; } /** * 3.创建RedisTemplate:用于执行Redis操作的方法 */ @Bean public RedisTemplate<String,Object> redisTemplate(JedisConnectionFactory factory){RedisTemplate<String, Object> template = new RedisTemplate<>();//关联template.setConnectionFactory(factory);//为key设置序列化器template.setKeySerializer(new StringRedisSerializer());//为value设置序列化器template.setValueSerializer(new StringRedisSerializer());return template; }}4.添加pojo

/** * @program: springboot-redis-demo * @description: Users * @author: 波波烤鸭 * @create: 2019-05-20 23:47 */public class Users implements Serializable { private Integer id; private String name; private Integer age; public Integer getId() {return id; } public void setId(Integer id) {this.id = id; } public String getName() {return name; } public void setName(String name) {this.name = name; } public Integer getAge() {return age; } public void setAge(Integer age) {this.age = age; } @Override public String toString() {return 'Users [id=' + id + ', name=' + name + ', age=' + age + ']'; }}5.单元测试

@RunWith(SpringRunner.class)@SpringBootTest(classes = SpringbootRedisDemoApplication.class)public class SpringbootRedisDemoApplicationTests { @Autowired private RedisTemplate<String, Object> redisTemplate; /** * 添加一个字符串 */ @Test public void testSet(){this.redisTemplate.opsForValue().set('key', 'bobokaoya...'); } /** * 获取一个字符串 */ @Test public void testGet(){String value = (String)this.redisTemplate.opsForValue().get('key');System.out.println(value); } /** * 添加Users对象 */ @Test public void testSetUesrs(){Users users = new Users();users.setAge(20);users.setName('张三丰');users.setId(1);//重新设置序列化器this.redisTemplate.setValueSerializer(new JdkSerializationRedisSerializer());this.redisTemplate.opsForValue().set('users', users); } /** * 取Users对象 */ @Test public void testGetUsers(){//重新设置序列化器this.redisTemplate.setValueSerializer(new JdkSerializationRedisSerializer());Users users = (Users)this.redisTemplate.opsForValue().get('users');System.out.println(users); } /** * 基于JSON格式存Users对象 */ @Test public void testSetUsersUseJSON(){Users users = new Users();users.setAge(20);users.setName('李四丰');users.setId(1);this.redisTemplate.setValueSerializer(new Jackson2JsonRedisSerializer<>(Users.class));this.redisTemplate.opsForValue().set('users_json', users); } /** * 基于JSON格式取Users对象 */ @Test public void testGetUseJSON(){this.redisTemplate.setValueSerializer(new Jackson2JsonRedisSerializer<>(Users.class));Users users = (Users)this.redisTemplate.opsForValue().get('users_json');System.out.println(users); }}
