启动项目报错handshake failed

## 问题描述
我按照readme里面的指引，首先复制了sdk的三个证书文件到resource目录，然后修改了application.yml配置

启动项目报handshake failed错误，message: not an SSL/TLS record


## 版本信息
fisco 2.4.0
国密版

## 重现步骤

** step1: 部署链，使用sdk和链交互**
[全过程步骤记录](https://gist.github.com/huahuayu/c32bb822786a263954649626803d68e8)

**step2: 配置示例springboot sdk项目**
克隆本项目，并将控制台的证书文件拷贝到resource文件夹


修改application.yml配置
```
encrypt-type: # 0:standard, 1:guomi
encrypt-type: 1

group-channel-connections-config:
caCert: classpath:ca.crt
sslCert: classpath:sdk.crt
sslKey: classpath:sdk.key
all-channel-connections:
- group-id: 1 #group ID
connections-str:
- 192.168.10.239:9025 # node listen_ip:channel_listen_port
- group-id: 2
connections-str:
- 192.168.10.239:9026 # node listen_ip:channel_listen_port
- group-id: 3
connections-str:
- 192.168.10.239:9027 # node listen_ip:channel_listen_port

channel-service:
group-id: 1 # The specified group to which the SDK connects
agency-name: agencyB # agency name

accounts:
pem-file: 0xcdcce60801c0a2e6bb534322c32ae528b9dec8d2.pem
p12-file: 0x98333491efac02f8ce109b0c499074d47e7779a6.p12
password: 123456
```

其中192.168.10.239:9025，9026，9027就是三个群组节点的channel_listen_port

另外**多问一句**：accounts是干嘛用的？

**step3: 启动项目，报错**
handshake failed错误，message: not an SSL/TLS record
