1.spring boot 整合redis

1.下载redis

2.配置Java代码：

2.1 添加spring boot maven 代码：

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

	<build>
		<plugins>
			<plugin>
				<groupId>org.springframework.boot</groupId>
				<artifactId>spring-boot-maven-plugin</artifactId>
			</plugin>
		</plugins>
	</build>

2.写controller：

设置实体： User：

  private String userName;
    private String password;
    private String email;
    private String birthDate;

3.配置redis 控制器文件：

@RestController
@RequestMapping("/redis")
public class RedisController {

    @Autowired
    private RedisTemplate redisTemplate;

    @RequestMapping("/save")
    public String save2Redis(@RequestParam("key") String key, @RequestParam("value") String value) {
        redisTemplate.opsForValue().set(key,value);
        return "OK";
    }

    @RequestMapping("/get/{key}")
    public String get4Redis(@PathVariable("key")String key) {
        return redisTemplate.opsForValue().get(key).toString();
    }

    @RequestMapping("/save2Hash")
    public String save2RedisHash(@RequestParam("key") String key,
                                 @RequestParam("field") String field,
                                 @RequestParam("value") String value) {
         redisTemplate.opsForHash().put(key,field,value);
         return "ok";
    }

    @RequestMapping("/get4Hash")
    public String get4RedisHash(@RequestParam("key") String key, @RequestParam("field") String field) {
        return redisTemplate.opsForHash().get(key,field).toString();
    }

配置Redis的模版文件：

@Configuration
public class RedisConfig {

   @Bean
    public RedisTemplate<Object, Object> redisTemplate(RedisConnectionFactory redisConnectionFactory)  {
        RedisTemplate<Object, Object> template = new RedisTemplate<>();
        template.setDefaultSerializer(new Jackson2JsonRedisSerializer<Object>(Object.class));
        template.setConnectionFactory(redisConnectionFactory);
        return template;
    }
}

3.配置redis的配置文件：yml 文件：

spring:
  redis:
    host: 47.104.128.12
    port: 6379
    password: 123456
    jedis:
      pool:
        max-active: 20
        max-idle: 10
        min-idle: 5
