【问题描述】（请对问题进行描述，方便定位问题）

用的是sdk-java-demo-v2.2.0 chain_client:

链ID

chain_id: "chain"

组织ID

org_id: "TestCMorg1"

客户端用户私钥路径

user_key_file_path: "C:\Users\itsij\Downloads\sdk-java-demo-v2.2.0\src\main\resources\crypto-config\TestCMorg1\user\cmtestuser1\cmtestuser1.tls.key"

客户端用户证书路径

user_crt_file_path: "C:\Users\itsij\Downloads\sdk-java-demo-v2.2.0\src\main\resources\crypto-config\TestCMorg1\user\cmtestuser1\cmtestuser1.tls.crt"

客户端用户交易签名私钥路径(若未设置，将使用user_key_file_path)

user_sign_key_file_path: "C:\Users\itsij\Downloads\sdk-java-demo-v2.2.0\src\main\resources\crypto-config\TestCMorg1\user\cmtestuser1\cmtestuser1.sign.key"

客户端用户交易签名证书路径(若未设置，将使用user_crt_file_path)

user_sign_crt_file_path: "C:\Users\itsij\Downloads\sdk-java-demo-v2.2.0\src\main\resources\crypto-config\TestCMorg1\user\cmtestuser1\cmtestuser1.sign.crt"

retry_limit: 10

同步交易结果模式下，每次轮训交易结果时的等待时间，单位：ms 删除此项或设为<=0则使用默认值 500

retry_interval: 500

当前签名证书的别名。当设置此配置项时，chain client 对象将自动检查链上是否已添加此别名，如果没有则自动上链此证书别名，

并且后续所有交易都会使用别名，别名可降低交易体大小。若为空则不启用。

alias: mycert5

nodes: - # 节点地址，格式为：IP:端口:连接数 node_addr: "47.110.150.177:12301" # 节点连接数 conn_cnt: 4 # RPC连接是否启用双向TLS认证 enable_tls: true # 信任证书池路径 trust_root_paths: - "src/main/resources/crypto-config/TestCMorg1/ca" # TLS hostname tls_host_name: "chainmaker.org" archive: # 数据归档链外存储相关配置 type: "mysql" dest: "root:root:localhost:3306" secret_key: xxx rpc_client: # grpc客户端最大接受容量(MB) max_receive_message_size: 16
