将 dataSourceProperties 添加到“deployNodes”时出错

Question

我想在 Corda 3.1 企业版中使用 Oracle 11g 数据库设置 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"
    }

}
}

我部署这个任务时出现错误：

 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”来连接这个节点到Oracle数据库？

@Henry，为了完成您在deployNodes 任务中要做的事情，您必须使用一个名为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"
    ]
  ...
  }

如果你正在修改一些node.conf文件，你可以直接使用dataSourceProperties.{}。

我认为该错误描述了 gradle 构建失败。所以肯定和gradle文件语法有关。只是想知道是否是因为在您的 gradle 文件中的 dataSourceProperties 标记之后缺少等号 (=)？

另请注意，有一组从内置资源文件加载的基本默认值 /node/src/main/resources/reference.conf :node gradle 模块。 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一组键（包括双引号），同时覆盖默认标记。

请通过更新 build.gradle 文件进行检查，如下所示：

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