前言
新开个坑，关于Redisson源码分析的，感觉不记一下，看完以后，过段时间又忘了...
源码下载
Redisson：https://github.com/redisson/redisson
本次源码我这下载的是3.17.7版本
3.17.7版本地址：Release redisson-3.17.7 · redisson/redisson · GitHub
其他准备
1.redis-server
Releases · microsoftarchive/redis · GitHub
因为用的系统是windows，所以redis可以直接下载windows 版本的，即开即用
2.RedisDesktopManager
开源Redis 可视化工具，这个有没有都可，主要是可视化，看起来方便点。
源码启动
- idea引入redisson-redisson-3.17.7 的pom看了一眼，分为很多包，其实看redisson的源码，核心的代码在redisson文件中。
- 退出来，重新在idea引入redisson中的pom.xml
- maven目录配置一下，拉下包
- 拉好以后，找下test 直接跑一个看看，理所当然的失败了
我的问题是因为默认的pom中的jar包版本，有些是必须要求jdk16的，有些是版本高了，不支持jdk8的。统一调一下。以下是我的pom文件配置，可以直接copy一下。

再试试，看看能不能起起来，还是报错。这次说是
品一品，也很正常，毕竟环境和redis这类的都没给人家配置，人按默认test走，链接得上还有鬼了。
看下代码：
我要test的是 RedissonLockTest#testTryLockWait
该类继承->BaseConcurrentTest->BaseTest
BaseTest 中有代码
@BeforeAll
public static void beforeClass() throws IOException, InterruptedException {
//尝试调用redis文件，启动一个redis-server
RedisRunner.startDefaultRedisServerInstance();
//连接redis-server，向test暴露一个由redisson实现的可用客户端
redisson = createInstance();
}实际上windows的这个redis启动，是一个exe程序，不需要代码帮助启动。我能否把第一行注释掉，直接改下配置，链接我已经启动的redis-server？
@BeforeAll
public static void beforeClass() throws IOException, InterruptedException {
//尝试调用redis文件，启动一个redis-server
//RedisRunner.startDefaultRedisServerInstance();
//连接redis-server，向test暴露一个由redisson实现的可用客户端
redisson = createInstance();
}
public static Config createConfig() {
// String redisAddress = System.getProperty("redisAddress");
// if (redisAddress == null) {
// redisAddress = "127.0.0.1:6379";
// }
Config config = new Config();
// config.setCodec(new MsgPackJacksonCodec());
// config.useSentinelServers().setMasterName("mymaster").addSentinelAddress("127.0.0.1:26379", "127.0.0.1:26389");
// config.useClusterServers().addNodeAddress("127.0.0.1:7004", "127.0.0.1:7001", "127.0.0.1:7000");
config.useSingleServer()
.setAddress("redis://127.0.0.1:6379");
// .setPassword("mypass1");
// config.useMasterSlaveConnection()
// .setMasterAddress("127.0.0.1:6379")
// .addSlaveAddress("127.0.0.1:6399")
// .addSlaveAddress("127.0.0.1:6389");
return config;
}或者 把 RedissonRuntimeEnvironment类中的redisBinaryPath 地址配置好（既上文准备1中redis-server.exe 的地址），createConfig不变：
config.useSingleServer() .setAddress(RedisRunner.getDefaultRedisServerBindAddressAndPort());
推荐这种做法，端口号自动生成，比较灵活。
执行：
成了，再看RDM中也有个30s过期的key
到这里，前期准备已经完全好了，只要能跑起来，能debug，剩余就是愿意花多少时间和精力的问题了
