@ConfigurationProperties获取配置文件值

在编写项目代码时，我们要求更灵活的配置，更好的模块化整合。在 Spring Boot 项目中，为满足以上要求，我们将大量的参数配置在 application.properties 或 application.yml 文件中，通过 @ConfigurationProperties 注解，我们可以方便的获取这些参数值

编写配置类

/**
 * @author wang.song
 * @date 2020-12-09 14:54
 * @Desc  获取properties中 spring.private.redis前缀的值
 */
@ConfigurationProperties(prefix = "spring.private.redis")
@Component
@Data
public class MyRedisProperties {
    /**
     * 模式
     */
    private Integer mode;
    /**
     * 密码
     */
    private String password;
    /**
     * 单机HOST:PORT
     */
    private String hostPort;
    /**
     * 单机port
     */
    private String port;
    /**
     * 哨兵名称
     */
    private String sentinelName;
    /**
     * 哨兵节点
     */
    private String sentinelnodes;
}

@EnableConfigurationProperties 进行注册

/**
 * @author wang.song
 * @date 2020-12-09 11:50
 * @Desc redisson 配置

@Slf4j
@Configuration
@EnableConfigurationProperties(MyRedisProperties.class)

    /**
     * 构建前缀
     */
    private static final String SENTINEL_PREFIX = "redis://";

    private static Config config = new Config();

    private static  Redisson redisson;


    @Bean

        setConfig(mode, myRedisProperties);
        redisson=(Redisson) Redisson.create(config);
