JAVA SpringBoot中使用redis的事务

本文介绍: 1、自定义redisConfig , 如果项目中要使用redis事务，最好将用事务和不用事务的redis分开。

@Order(value = 1)
@Data
@Component
public class RedisProperties {

    @Value("${spring.redis.host}")
    private String host;

    @Value("${spring.redis.port}")
    private Integer port;

    @Value("${spring.redis.password}")
    private String password;

    @Value("${spring.redis.database}")
    private Integer database;

    @Value("${spring.redis.timeout}")
    private Integer timeout;

    @Value("${spring.redis.lettuce.pool.max-idle}")
    public Integer maxIdle;

    @Value("${spring.redis.lettuce.pool.min-idle}")
    public Integer minIdle;

    @Value("${spring.redis.lettuce.pool.max-active}")
    public Integer maxActive;

    @Value("${spring.redis.lettuce.pool.max-wait}")
    public Integer maxWait;



}

需要事务的注入

@Resource(name = "redisTransactionTemplate")

不需要事务的注入

@Resource(name = "redisTemplate")

事务完整执行流程

redisTransactionTemplate.multi();   //开启

redisTransactionTemplate.exec();  //执行

redisTransactionTemplate.discard();  //取消
