Java SDK 2.x连接节点失败
JavaSDK连接节点失败排查思路
Important: 前置说明
1. jdk版本支持
JavaSDK原则上支持从jdk 1.8到jdk 15的OracleJDK和OpenJDK，但中间有部分版本禁用或者不支持secp256k1曲线，会导致sdk与节点之间握手失败，请首先检查当前使用的jdk是否支持secp256k1曲线，目前已经覆盖测试的jdk版本如下，推荐大家使用：
-
OracleJDK:- 1.8.0_141
- 1.8.0_202
- 11.0.2
- 14.0.2
- 15.0.2
-
OpenJDK:- 11.0.2
- 14.0.2
- 15.0.2
-
jdk下载链接:
- OracleJDK官网:
- https://www.oracle.com/java/technologies/downloads/archive/
- 国内镜像:
- http://www.codebaoku.com/jdk/jdk-oracle.html
- http://www.codebaoku.com/jdk/jdk-openjdk.html
- OracleJDK官网:
若使用的jdk禁用了secp256k1曲线(注意: 如果jdk不支持secp256k1曲线，不适用该方法)，可以参考 #issue 470通过手动修改java.security属性的方式重新启用secp256k1曲线.
2. JavaSDK版本说明
JavaSDK 2.8.1优化了sdk连接失败的日志和报错提示，欢迎使用2.8.1以及以上版本的sdk，更便于定位错误问题。
maven方式

}
}
排查步骤
JavaSDK启动失败时会有类似于如下的异常信息:
* TRACE INFORMATION:
----------------------------
====> STEP1: try to connect nodes with ecdsa context...
<==== STEP1 Result: try to connect nodes with ecdsa context failed for cert missing
* Missed certificates: [conf/ca.crt,conf/sdk.crt,conf/sdk.key,]
currentPath: /Users/octopus/fisco/asset-app/dist
----------------------------
====> STEP2: connect nodes with ecdsa context failed, try to connect nodes with sm-context...
<==== STEP2 Result: connect with sm context failed for cert missing.
* Missed certificates:
[conf/gm/gmca.crt,conf/gm/gmsdk.crt,conf/gm/gmsdk.key,conf/gm/gmensdk.key,conf/gm/gmensdk.crt,]
currentPath: /Users/octopus/fisco/asset-app/dist
----------------------------
<====> Error: try to connect nodes with both ecdsa and sm context failed <====>
<====> Please refer to github issue: https://github.com/FISCO-BCOS/java-sdk/issues/536
<====> Please refer to fisco-docs: https://fisco-bcos-documentation.readthedocs.io/zh_CN/latest/docs/faq/connect.html
----------------------------
* FISCO BCOS Java SDK Version: 2.8.1
* Support secp256k1 : true
* Java Version : 15.0.2
* JDK Disabled NamedCurves : null
* JDK DisableNative Option : null
* OS Name : Mac OS X
* OS Arch : x86_64
* OS Version : 10.16
* JVM Version : 15.0.2+7-27
* JVM Vendor : Oracle Corporation
* JVM Vendor URL : https://java.oracle.com/
不同的项目对错误的处理方式不同，这段错误信息可能会重复显示多次，用户从最后的RACE INFORMATION:开始排查即可。
step1：检查是否拷贝证书
若sdk同时抛出下面两个错误，说明没有拷贝证书，需要将证书拷贝到src/main/resources/conf子目录或conf子目录下：
<==== STEP1 Result: try to connect nodes with ecdsa context failed for cert missing
* Missed certificates: xxxxxx
<==== STEP2 Result: connect with sm context failed for cert missing.
* Missed certificates: xxxxxx
证书拷贝步骤可参考FISCO BCOS文档：搭建第一个区块链网络
step2: 检查节点是否启动或者sdk与节点之间网络是否连通
若sdk抛出如下错误，说明sdk与节点之间网络不连通，或者节点没有启动：
* TRACE INFORMATION:
----------------------------
====> STEP1: try to connect nodes with ecdsa context...
<==== STEP1-1: Load certificates for ecdsa context success...
<==== connect nodes failed, reason:
Failed to connect to all the nodes!
* connect to 127.0.0.1:20200 failed! Please make sure the nodes have been started, and the network between the SDK and the nodes are connected normally.reason: Connection refused: /127.0.0.1:20200
* connect to 127.0.0.1:20201 failed! Please make sure the nodes have been started, and the network between the SDK and the nodes are connected normally.reason: Connection refused: /127.0.0.1:20201
通过ps命令检查节点进程是否启动:
# 到节点所在机器运行ps命令
ps aux |grep -i fisco-bcos
通过telnet命令检查sdk到节点的网络是否连通:
telnet ${节点ip} ${节点channel_listen_port}
注意：channel_listen_port，在节点config.ini配置文件中：
$ cat node0/config.ini | egrep channel_listen
channel_listen_ip=0.0.0.0
channel_listen_port=20208
step3: 检查证书是否拷贝正确
保证项目打开java-sdk日志，在日志中grep SSLHandshakeException 或ValidatorException或者secp256k1`：
grep -iE 'SSLHandshakeException|ValidatorException|secp256k1' sdk.log
若输出如下错误说明放置在sdk中的证书错误，需要重新配置证书：
...
sun.security.validator.ValidatorException: PKIX path validation failed: java.security.cert.CertPathValidatorException: Path does not chain with any of the trust anchors
Caused by: java.security.cert.CertPathValidatorException: Path does not chain with any of the trust anchors
sun.security.validator.ValidatorException: PKIX path validation failed: java.security.cert.CertPathValidatorException: Path does not chain with any of the trust anchors
Caused by: java.security.cert.CertPathValidatorException: Path does not chain with any of the trust anchors
javax.net.ssl.SSLHandshakeException: General OpenSslEngine problem
Caused by: sun.security.validator.ValidatorException: PKIX path validation failed: java.security.cert.CertPathValidatorException: Path does not chain with any of the trust anchors
Suppressed: javax.net.ssl.SSLHandshakeException: error:14090086:SSL routines:ssl3_get_server_certificate:certificate verify failed
Caused by: java.security.cert.CertPathValidatorException: Path does not chain with any of the trust anchors
javax.net.ssl.SSLHandshakeException: General OpenSslEngine problem
...
Note: 若这里输出disable secp256k1的日志，说明握手失败是由于jdk禁用secp256k1曲线导致的，可继续转step4排查。
step4： 非国密区块链-检查jdk是否支持secp256k1曲线
Note: 国密区块链且采用国密SSL连接可跳过本检查步骤。
FISCO BCOS非国密默认采用secp256k1曲线，但随着jdk版本的升级，secp256k1曲线逐渐被弃用（因此2.9.0版本在保证向下兼容的同时，非国密连接采用RSA曲线），对于采用非国密SSL的区块链(节点的config.ini配置sm_channel_crypto=false)，在sdk日志中grep关键字disable.*secp256k1：
cat sdk.log|grep -i 'disable.*secp256k1'
若有如下输出，说明当前jdk不支持secp256k1曲线，则需要参考#issue 470 手动修改java.security属性启用secp256k1曲线或者替换到支持secp256k1曲线的jdk版本：
Caused by: sun.security.validator.ValidatorException: PKIX path validation failed: java.security.cert.CertPathValidatorException: Algorithm constraints check failed on disabled algorithm: secp256k1
Caused by: java.security.cert.CertPathValidatorException: Algorithm constraints check failed on disabled algorithm: secp256k1
Caused by: java.security.cert.CertPathValidatorException: Algorithm constraints check failed on disabled algorithm: secp256k1
Caused by: sun.security.validator.ValidatorException: PKIX path validation failed: java.security.cert.CertPathValidatorException: Algorithm constraints check failed on disabled algorithm: secp256k1
Caused by: java.security.cert.CertPathValidatorException: Algorithm constraints check failed on disabled algorithm: secp256k1
Caused by: java.security.cert.CertPathValidatorException: Algorithm constraints check failed on disabled algorithm: secp256k1
Note: jdk曲线的变更均会记录在release notes中，具体可参考 https://www.oracle.com/java/technologies/javase/jdk-relnotes-index.html。
step5： 国密区块链 && 启用国密SSL连接 --- 检查netty库是否冲突
Note: 非国密区块链或者国密区块链但没有开启国密SSL连接可跳过本检查步骤。
FISCO BCOS国密区块链若开启国密SSL连接(节点的config.ini配置sm_channel_crypto=true)，可能因为netty库冲突，导致sdk连接节点失败。
Java SDK默认的netty库版本是netty-4.1.53.Final，Spring-boot等其他组件若和Java SDK一起使用，会引入高版本或者低版本的netty，从而因netty冲突导致sdk连接节点失败。
对于本情况，可在sdk日志中grep关键字NoSuchMethodError或netty关键字：
cat sdk.log|grep -E 'NoSuchMethodError|netty'
若输出如下日志，说明netty库冲突：(这里的示例是spring采用了高版本的netty-4.1.60.Final，java-sdk不支持该版本的netty)。

此时参考#issue 332，指定netty版本为4.1.53解决冲突，大致写法如下：
<dependency>
<groupId>io.netty</groupId>
<artifactId>netty-all</artifactId>
<version>4.1.53.Final</version>
</dependency>
<dependency>
<groupId>org.fisco-bcos.java-sdk</groupId>

<version>2.8.0</version>
<exclusions>
<exclusion>
<groupId>io.netty</groupId>
<artifactId>netty-all</artifactId>

</exclusions>
</dependency>
spring + java-sdk 构建应用，强烈推荐参考应用spring-boot-crud:
2.8.1版本官方会优化SDK连接失败的日志和报错提示，欢迎试用2.8.1-SNAPSHOT版本。
若有其他连接失败的场景出现，欢迎补充本issue。

证书已拷贝，通过检查日志可知证书拷贝正确
jdk版本也支持secp256k1
问题应该是区块链节点运行的端口有问题，启动的nodes运行在30300-30303
于是尝试修改dist/conf中与端口相关的几个文件内容，手动改成30300-30303
但还是会报相同的错误..
尝试其他方法暂未解决问题
有办法指定nodes运行在20200-20203端口吗？这样应该就不会ssl handshake failed了吧
