springboot 1.5 -> 2.0 へアップグレード #66

Closed soudegesu closed 6 years ago

soudegesu commented 6 years ago

対応したことメモをする。 今の所の予想

soudegesu commented 6 years ago

まずは、 springboot-actuator のメトリック設定を確認する

この中で監視に使用しているメトリックはどれかというと。。

soudegesu commented 6 years ago

以下の6つぽい

soudegesu commented 6 years ago

datadog の gauge で打ち上げているロジックのエンドポイントを↑のパラメータにしてあげればよさそう。 packerで作成しているAMI内に含めているpythonスクリプトを修正してあげればよさそう

soudegesu commented 6 years ago

次にログフォーマットは

soudegesu commented 6 years ago

とりあえず springboot のバージョンを上げてみる

soudegesu commented 6 years ago

コンパイルエラーが出た

findById(java.lang.String)はorg.springframework.data.repository.CrudRepositoryのfindById(ID)と競合します
  戻り値の型XXXXXはjava.util.Optional<XXXXX>と互換性がありません
soudegesu commented 6 years ago

Optional<型> になったぽいのでそちらに修正する

soudegesu commented 6 years ago

次に

Error:(21, 34) java: シンボルを見つけられません
  シンボル:   メソッド findOne(long)
  場所: タイプXXXXXXの変数 identityRepository
soudegesu commented 6 years ago

findOne がなくなったので findById を使う

soudegesu commented 6 years ago

ErrorAttributes はパッケージが変更されているため修正 org.springframework.boot.autoconfigure.web.ErrorAttributes から org.springframework.boot.web.servlet.error.ErrorAttributes へ overrideしないといけないメソッドの引数も型が変わっている

soudegesu commented 6 years ago

dropwizardMetricで取得していた拡張メトリックは監視で使用していないため、削除する.

例えば、以下で取得する /actuator/metrics/tomcat.sessions.created

{
    "name": "tomcat.sessions.created",
    "measurements": [
        {
            "statistic": "COUNT",
            "value": 0
        }
    ],
    "availableTags": []
}
