如何從 jboss cli 讀取引導錯誤？

Question

當通過 jboss-cli ( deploy --file on_controller.war ) 使用 hot-deploy 並且部署它時出現問題，有一些 output 描述了這個問題，例如（實際上並不是那么漂亮。^^）：

{
    "WFLYCTL0080: Failed services" => {
        "jboss.undertow.deployment.default-server.default-host./THE_WAR" =>
            "< some description containing exceptions etc >"
    }
}

不使用熱部署時，例如在standlone.xml中使用<fs-archive />時；
如何使用 jboss-cli 讀取此錯誤？

我知道有deployment-info命令，但它只告訴部署是否失敗，而不是為什么。
我也試過/deployment=*:query() ，但它也只包含部署是否失敗。

此外:read-attribute(server-state)將返回"running" ，即使在引導期間出現錯誤也是如此。

您可以嘗試/core-service=management:read-boot-errors ：

[standalone@jboss:9990 /] /core-service=management:read-boot-errors
{
    "outcome" => "success",
    "result" => []
}

Because that output can be a little bit hard to parse when using automation , you can also use JBoss' HTTP Management API , which will give you JSON:

$ curl --digest --location --dump-header - http://$JBOSS_HOST:9990/management/ \
    --header "Content-Type: application/json" --data - --user admin <<EOT
{
    "address": {
        "core-service": "management"
    },
    "operation": "read-boot-errors",
    "json.pretty": 1
}
EOT
