运行 Sample 代码时出现空指针错误

[wuyg123]

创建一份错误报告需要您填写以下内容：

概述

在按照官方文档进行WeIdentity入门时，到了运行 Sample 代码步骤时，已按照官方文档进行配置后运行，结果运行失败，错误为空指针异常，我怀疑是配置时出现错误，但不知道如何正确去配置。

复现

1.1 下载 WeIdentity-Sample 源码：
git clone https://github.com/WeBankBlockchain/WeIdentity-Sample

1.2 配置基本信息：
修改application.properties文件，主要修改下面这两个参数，其他参数使用默认即可，也可以根据实际需要修改：
#0非国密，1国密
encrypt.type=0
#2 FISCO BCOS V2，3 FISCO BCOS V3
bcos.version=2
#database数据库模式，blockchain区块链模式
deploy.style=database

如果您是第一次运行 WeIdentity-Sample，您需要先进行编译：
chmod +x build.sh
./build.sh

2.1 启用服务：

chmod +x build.sh start.sh stop.sh
./start.sh

在这里运行时报错

环境

• 区块链类型（FISCO-BCOS，Fabric，Ethereum）：FISCO-BCOS
• 区块链版本及网络：2
• WeIdentity版本：3.1.0

其他内容

配置文件

/home/bigwu/WeIdentity-Sample/resources/application.properties
内容：

#the private key storage path of SDK
admin.privKeyPath=./keys/priv/ecdsa_key
#the private key storage path of weId
weid.keys.dir=./keys/

admin.privKey.dir=./keys/priv/

resources.dir=./resources/

is open swagger ui, value is true or false

mconfig.swagger-ui-open=true

config swagger host address, when nginx deploy, the interface of the swagger-ui.html will access.

#springfox.documentation.swagger.v2.host=localhost:${http.port}

#0非国密，1国密
encrypt.type=0
#2 FISCO BCOS V2，3 FISCO BCOS V3
bcos.version=2
#database数据库模式，blockchain区块链模式
deploy.style=blockchain
