spring boot 整合 redis

1、先创建spring boot项目

 

2、添加redis依赖

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
   xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
   <modelVersion>4.0.0</modelVersion>

   <groupId>com.daqsoft</groupId>
   <artifactId>demo</artifactId>
   <version>0.0.1-SNAPSHOT</version>
   <packaging>jar</packaging>
   <name>demo</name>
   <description>Demo project for Spring Boot</description>

      <artifactId>spring-boot-starter-parent</artifactId>
      <version>1.5.3.RELEASE</version>
      <relativePath/> <!-- lookup parent from repository -->
   </parent>

   <properties>
      <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
      <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
      <java.version>1.8</java.version>
   </properties>

   <dependencies>
      <dependency>
         <groupId>org.springframework.boot</groupId>
         <artifactId>spring-boot-starter-web</artifactId>
      </dependency>

      <dependency>
         <groupId>org.springframework.boot</groupId>
         <artifactId>spring-boot-starter-test</artifactId>
         <scope>test</scope>
      </dependency>

　　　　//添加redis依赖，其他依赖信息在创建spring boot项目回自动创建
　　　　<dependency>
   　　　　<groupId>org.springframework.boot</groupId>
  　　　　 <artifactId>spring-boot-starter-redis</artifactId>
  　　 　　<version>1.4.3.RELEASE</version>
　　　　</dependency>
   </dependencies>
   <build>
      <plugins>
         <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
         </plugin>
      </plugins>
   </build>
</project>

 

3、添加redis相关配置(可直接在properties文件中配置，也可以创建yml文件配置，使用yml文件时注意格式)

# Redis数据库索引（默认为0）
spring.redis.database=0
# Redis服务器地址
spring.redis.host=192.168.2.67
# Redis服务器连接端口
spring.redis.port=6379
# Redis服务器连接密码（默认为空）
spring.redis.password=
# 连接池最大连接数（使用负值表示没有限制）
spring.redis.pool.max-active=8
# 连接池最大阻塞等待时间（使用负值表示没有限制）
spring.redis.pool.max-wait=-1
# 连接池中的最大空闲连接
spring.redis.pool.max-idle=8
# 连接池中的最小空闲连接
spring.redis.pool.min-idle=0
# 连接超时时间（毫秒）
spring.redis.timeout=0

 

4、添加redis配置类

@Configuration
@EnableCaching
public class RedisConfig extends CachingConfigurerSupport {
    /**
     * 生成key的策略
     * @return
     */
    @Bean
    public KeyGenerator wiselyKeyGenerator(){
        return new KeyGenerator() {
            @Override
            public Object generate(Object target, Method method, Object... params) {
                StringBuilder sb = new StringBuilder();
                sb.append(target.getClass().getName());
                sb.append(method.getName());
                for (Object obj : params) {
                    sb.append(obj.toString());
                }
                return sb.toString();
            }
        };
    }

    /**
     * 管理缓存
     * @param redisTemplate
     * @return
     */

    @Bean
    public CacheManager cacheManager(
            @SuppressWarnings("rawtypes") RedisTemplate redisTemplate) {
        return new RedisCacheManager(redisTemplate);
    }


    /**
     * RedisTemplate配置
     * @param factory
     * @return
     */
    @Bean
    public RedisTemplate<String, String> redisTemplate( RedisConnectionFactory factory) {
        StringRedisTemplate template = new StringRedisTemplate(factory);
        Jackson2JsonRedisSerializer jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer(Object.class);
        ObjectMapper om = new ObjectMapper();
        //所有的属性都可以访问到(private到public)
        om.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);
        om.enableDefaultTyping(ObjectMapper.DefaultTyping.NON_FINAL);
        jackson2JsonRedisSerializer.setObjectMapper(om);
        template.setValueSerializer(jackson2JsonRedisSerializer);
        template.afterPropertiesSet();
        return template;
    }
}

 

5、配置完成，书写测试服务（redisTemplate常用API）

@Service
public class RedisService {

    @Autowired
    private RedisTemplate redisTemplate;

    /**
     * 写入缓存
     * @param key
     * @param val
     * @return
     */
    public boolean save(String key,Object val){
        boolean result = false;
        try {
            ValueOperations<Serializable, Object> operations = redisTemplate.opsForValue();
            operations.set(key, val);
            result = true;
        } catch (Exception e) {
            e.printStackTrace();
        }
        return result;
    }

    /**
     * 写入缓存并设置失效时间
     * @param key
     * @param value
     * @param expireTime
     * @return
     */
    public boolean save(final String key, Object value, Long expireTime) {
        boolean result = false;
        try {
            ValueOperations<Serializable, Object> operations = redisTemplate.opsForValue();
            operations.set(key, value);
            redisTemplate.expire(key, expireTime, TimeUnit.SECONDS);
            result = true;
        } catch (Exception e) {
            e.printStackTrace();
        }
        return result;
    }

    /**
     * 批量删除对应的value
     * @param keys
     */
    public void remove(final String... keys) {
        for (String key : keys) {
            remove(key);
        }
    }

    /**
     * 批量删除key
     * @param pattern
     */
    public void removePattern(final String pattern) {
        Set<Serializable> keys = redisTemplate.keys(pattern);
        if (keys.size() > 0)
            redisTemplate.delete(keys);
    }
    /**
     * 删除对应的value
     * @param key
     */
    public void remove(final String key) {
        if (exists(key)) {
            redisTemplate.delete(key);
        }
    }
    /**
     * 判断缓存中是否有对应的value
     * @param key
     * @return
     */
    public boolean exists(final String key) {
        return redisTemplate.hasKey(key);
    }
    /**
     * 读取缓存
     * @param key
     * @return
     */
    public Object get(final String key) {
        Object result = null;
        ValueOperations<Serializable, Object> operations = redisTemplate.opsForValue();
        result = operations.get(key);
        return result;
    }
    /**
     * 哈希 添加
     * @param key
     * @param hashKey
     * @param value
     */
    public void hmSet(String key, Object hashKey, Object value){
        HashOperations<String, Object, Object> hash = redisTemplate.opsForHash();
        hash.put(key,hashKey,value);
    }

    /**
     * 哈希获取数据
     * @param key
     * @param hashKey
     * @return
     */
    public Object hmGet(String key, Object hashKey){
        HashOperations<String, Object, Object>  hash = redisTemplate.opsForHash();
        return hash.get(key,hashKey);
    }

    /**
     * 列表添加
     * @param k
     * @param v
     */
    public void lPush(String k,Object v){
        ListOperations<String, Object> list = redisTemplate.opsForList();
        list.rightPush(k,v);
    }

    /**
     * 列表获取
     * @param k
     * @param l
     * @param l1
     * @return
     */
    public List<Object> lRange(String k, long l, long l1){
        ListOperations<String, Object> list = redisTemplate.opsForList();
        return list.range(k,l,l1);
    }

    /**
     * 集合添加
     * @param key
     * @param value
     */
    public void add(String key,Object value){
        SetOperations<String, Object> set = redisTemplate.opsForSet();
        set.add(key,value);
    }

    /**
     * 集合获取
     * @param key
     * @return
     */
    public Set<Object> setMembers(String key){
        SetOperations<String, Object> set = redisTemplate.opsForSet();
        return set.members(key);
    }

    /**
     * 有序集合添加
     * @param key
     * @param value
     * @param scoure
     */
    public void zAdd(String key,Object value,double scoure){
        ZSetOperations<String, Object> zset = redisTemplate.opsForZSet();
        zset.add(key,value,scoure);
    }

    /**
     * 有序集合获取
     * @param key
     * @param scoure
     * @param scoure1
     * @return
     */
    public Set<Object> rangeByScore(String key,double scoure,double scoure1){
        ZSetOperations<String, Object> zset = redisTemplate.opsForZSet();
        return zset.rangeByScore(key, scoure, scoure1);
    }
}

6、测试类

@RestController
@RequestMapping("redis")
public class TestRedisCtrl {
    @Autowired
    private RedisService redisService;
    @RequestMapping(value = "/test")
    public String redisTest() {
        StringBuffer sb = new StringBuffer();
        redisService.save("str", "str");
        sb.append("str=").append(redisService.get("str").toString()).append(",");
        redisService.hmSet("hmset","key","val");
        sb.append("hmset=").append(redisService.hmGet("hmset","key")).append(",");
        redisService.lPush("list","val");
        sb.append("list=").append(redisService.lRange("list",0,1).toString()).append(",");
        redisService.add("set","val");
        sb.append("set=").append(redisService.setMembers("set").toString()).append(",");
        redisService.zAdd("zset","val1",1);
        redisService.zAdd("zset","val2",2);
        sb.append("zset=").append(redisService.rangeByScore("zset",1,2)).append(",");
        return sb.toString();
    }

    @RequestMapping(value = "/user")
    public Object redisBeanTest(){
        UserBean userBean = new UserBean();
        userBean.setUserName("test");
        userBean.setAge("18");
        redisService.save("user",userBean);
        return redisService.get("user");
    }
}

7、启动服务，访问测试方法，获取正确信息

　　

　　

 

　　查看redis桌面管理器，对应值正确添加

　　

 

 

　　特殊：安装redis服务及redis桌面管理器，方便测试和查看
