Question

我想在Corda 3.1企业版中使用Oracle 11g数据库设置一个Corda节点：

apply plugin: 'kotlin'
apply plugin: 'idea'
apply plugin: 'net.corda.plugins.cordapp'
apply plugin: 'net.corda.plugins.cordformation'
apply plugin: 'net.corda.plugins.quasar-utils'
apply plugin: 'maven-publish'
jar.baseName = "cordapp-example"

task deployNodes(type: net.corda.plugins.Cordform, dependsOn: ['jar']) {
directory "./build/nodes"
node {
    name "O=Notary Pool,L=Sao Paolo,C=BR"
    notary = [validating : false]
    p2pPort 10002
    rpcSettings {
        address("localhost:10003")
        adminAddress("localhost:10043")
    }
    webPort 10004
    cordapps = ["$corda_release_group:corda-finance:$corda_release_version"]
    rpcUsers = [[ user: "user1", "password": "test", "permissions": ["ALL"]]]
}
node {
    name "O=First Bank of London,L=London,C=GB"
    p2pPort 10005
    rpcSettings {
        address("localhost:10006")
        adminAddress("localhost:10046")
    }
    webPort 10007
    cordapps = ["$corda_release_group:corda-finance:$corda_release_version"]
    rpcUsers = [[ user: "user1", "password": "test", "permissions": ["ALL"]]]
    dataSourceProperties {
        dataSourceClassName = "oracle.jdbc.pool.OracleDataSource"
        dataSource.url = "jdbc:oracle:thin:@localhost:1521:db11g2"
        dataSource.user = "sys"
        dataSource.password = "98765"
    }
    database = {
        transactionIsolationLevel = READ_COMMITTED
        schema = "db11g2"
    }

}
}

部署此任务时出现错误：

 FAILURE: Build failed with an exception.

 * Where:
 Build file 'D:\WorkPlaceCorda\TestDatabase\cordapp-example\kotlin-source\build.gradle' line: 94

 * What went wrong:
 A problem occurred evaluating project ':kotlin-source'.
 Could not find method dataSourceProperties() for arguments [build_4c7s0yjnncjhr0s832fhma3b4$_run_closure6$_closure16$_closure21@45dad5d1] on object of type net.corda.plugins.Node.

那么，如何配置参数“ dataSourceProperties”以将此节点连接到Oracle数据库？

@Henry，为了完成您在deployNodes任务中想要做的事情，您必须使用名为extraConfig的条目，如下所示：

task deployNodes(type: net.corda.plugins.Cordform, dependsOn: ['jar']) {
...
  node {
  ...
     extraConfig = [
       "dataSourceProperties.dataSourceClassName"  = "oracle.jdbc.pool.OracleDataSource",
       "dataSourceProperties.dataSource.url"       = "jdbc:oracle:thin:@localhost:1521:db11g2",
       "dataSourceProperties.dataSource.user"      = "sys",
       "dataSourceProperties.dataSource.password"  = "98765",
       "database.transactionIsolationLevel"        = "READ_COMMITED",
       "database.schema"                           = "YOUR_DB_SCHEMA",
       "database.runMigration"                     = "true"
    ]
  ...
  }

如果您正在修改某些dataSourceProperties.{}文件，则可以直接使用node.conf。

我认为该错误描述了gradle构建失败。因此，它必须与gradle文件语法相关。只想知道是否是由于在gradle文件中的dataSourceProperties标记之后缺少了等号（ = ）？

还要注意，从内置资源文件中加载了一组基本的默认值：node gradle模块的 /node/src/main/resources/reference.conf 。 dataSourceProperties标记存在于默认的参考配置集中。我们应该使用完全相同的键集（包括双引号），同时覆盖默认标记。

请通过如下方式更新build.gradle文件进行检查：

dataSourceProperties = {
    dataSourceClassName = "oracle.jdbc.pool.OracleDataSource"
    "dataSource.url" = "jdbc:oracle:thin:@localhost:1521:db11g2"
    "dataSource.user" = "sys"
    "dataSource.password" = "98765"
}

将dataSourceProperties添加到“ deployNodes”时出错
