seata1.0redis自动注入失败一共有两个问题,
1:不支持密码
2:转换异常
做如下修改
@component
@ConfigurationProperties(prefix = REGISTRY_REDIS_PREFIX)
public class RegistryRedisProperties {
private String serverAddr = "localhost:6379";
private String db = "0";
private String password = "";

public String getServerAddr() {
	return serverAddr;
}

public RegistryRedisProperties setServerAddr(String serverAddr) {
	this.serverAddr = serverAddr;
	return this;
}

public String getPassword() {
	return password;
}

public RegistryRedisProperties setPassword(String password) {
	this.password = password;
	return this;
}

public String getDb() {
	return db;
}

public RegistryRedisProperties setDb(String db) {
	this.db = db;
	return this;
}

}
/**
* getRedisDbFileKey()获取的是key,不是value,无法强转,导致 unable not cast
*/
int db = seataConfig.getInt(seataConfig.getConfig(getRedisDbFileKey()));

@renyuanxin111 类型已经修复，fix #2160

[slievrly]

I haven't actually verified this pr, but I think the problem is that we need int type but reflection returns Object. Can you add unit tests about this pr?

[guojingyinan219]

@slievrly I don't know how to write this unit test. I package seata-spring-boot-starter and run in my program with debug, it's ok

[guojingyinan219]

if look like you describe, serverAddr can not read and return Object ,but is ok

[slievrly]

LGTM, but test coverage is reduced a lot.
