Springでlog4j2(Gradleでプロジェクト作成)

以前にSpringでlog4jをmavenの設定で使用するようにしたことがあったけど、今回はGraldeで行ってみる。

SpringでLog4j2

build.gradleファイルを開いて、log4j2を取り込む設定を記述する。

build.gradleの設定内容は次のとおり。

buildscript {
    ext {
        springBootVersion = '1.5.13.BUILD-SNAPSHOT'
    }
    repositories {
        mavenCentral()
        maven { url "https://repo.spring.io/snapshot" }
        maven { url "https://repo.spring.io/milestone" }
    }
    dependencies {
        classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}")
    }
}

apply plugin: 'java'
apply plugin: 'eclipse'
apply plugin: 'org.springframework.boot'

group = 'com.example'
version = '0.0.1-SNAPSHOT'
sourceCompatibility = 1.8

repositories {
    mavenCentral()
    maven { url "https://repo.spring.io/snapshot" }
    maven { url "https://repo.spring.io/milestone" }
}


dependencies {
    compile('org.springframework.boot:spring-boot-starter-web') {
        exclude group: 'org.springframework.boot', module: 'spring-boot-starter-logging'
    }
    compile('org.springframework.boot:spring-boot-starter-log4j2')
    testCompile('org.springframework.boot:spring-boot-starter-test')
}

build.gradleを選択したまま、コンテキストメニューを表示して、「Gradle」-「Refresh Gradle Project」をクリック。

src/main/javaを選択したまま、コンテキストメニューを表示して、「New」-「File」をクリック。

File name: に log4j2.xml を入力して「Finish」をクリック。

log4j2.xmlにログ出力の設定内容を記述する。

log4j2.xmlの設定は次のとおり。

<?xml version="1.0" encoding="UTF-8"?>

        <Property name="app_name">hoge</Property>
        <Property name="date">%d{yyyy-MM-dd HH:mm:ss.SSS}</Property>

前回の記事で作成したHogeController.javaにログ出力のコードを追加する。

SpringでHello world(Gradleでプロジェクト作成)

private static・・・、Logger.info("#index START")とimport文が追加になる。

HogeController.javaのソースは次のとおり。

package com.example.hoge;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class HogeController {

    private static final Logger logger = LoggerFactory.getLogger(HogeController.class);

    @RequestMapping("/")
    public String index() {
        logger.info("#index START");
        return "Hello World.";
    }
}

log4j2の設定が終わったので、Springを動かしてログ出力されているかを確認する。
プロジェクトを選択したまま、メニューバーの「Run」-「Run As」-「4 Spring Boot App」をクリック。

Hello World. の表示を前回同様に確認する。

プロジェクトを選択したまま、コンテキストメニューを表示して「Refresh」をクリック。

log4j2.xmlで設定したとおりに、logsフォルダが作成され、その下にログが出力されている。これでおわり。

SpringでHello world(Gradleでプロジェクト作成)

Spring Tool SuiteにBuildshipをインストールしたので、プロジェクトを作成し、HelloWorldをしてみる。

Package Explorer上でポップアップを表示させ、「New」-「Spring Starter Project」をクリック。

Name に hoge を入力。
Type: は Gradle (Buildship 2.x) を選択。
Package に com.example.hoge を入力。
「Next」をクリック。

Web をチェックして、「Next」をクリック。

「Finish」をクリック。

プロジェクトができているので、 com.exmple.hoge パッケージにHelloWorld出力用のクラスを作成する。
com.exmple.hoge パッケージを選択して、ポップアップを表示して、「New」-「Class」をクリック。

Name: に HogeController を入力して、「Finish」をクリック。

HogeControllerのプログラムを次のようにコーディングする。

package com.example.hoge;

import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class HogeController {

    @RequestMapping("/")
    public String index() {
        return "Hello World.";
    }
}

メニューバーの「Run」-「Run As」-「4 Spring Boot App」をクリック。

Spring Boot app起動のログがコンソールに出力される。
Started HogeApplication・・・と出力されていたら、ブラウザで動作確認できる。

ブラウザで動作確認する。
アドレスバーに、 http://localhost:8080 を入力。
Hello World. が出力された。おわり。

Spring Tool SuiteにBuildshipをインストール

以前にSTS Gradleをインストールしたけど、"Migration from STS Gradle to Buildship" The STS Gradle plugin is under minimal maintenance and may be discontinued in the future. A document explaining the migration process from STS Gradle to Buildship can be found here ってメッセージが表示した。

Spring Tool SuiteにGradleのプラグインをインストール

なので、Buildshipをインストールすることにした。

hereのリンク(Migration guide from STS Gradle to Buildship)をクリックすると、STS GradleからBuildshipの移行方法が書いてあるサイトが表示される。
移行の手順は次のように書いてある。

まず、手順1にしたがって、最新のBuildshipをインストールすることにする。
(手順1 Install the latest Buildship release. Download locations and instructions are in the Buildship)


メニューバーの 「Help」-「Install New Software...」を選択。

Work with: に http://download.eclipse.org/buildship/updates/e47/releases/2.x を入力して、「Add...」をクリック。

Name: に Buildship 2.x
Location: に http://download.eclipse.org/buildship/updates/e47/releases/2.x を入力して、「OK」をクリック。

Buildship: Eclipse Plug-ins for Gradle がチェックの状態で「Next」をクリック。

「Next」をクリック。

I accept the terms of the license agreement を選択して、「Finish」をクリック。

Spring Tool Suiteの再起動が促されるので、「Restart Now」をクリック。

Spring Tool Suiteの再起動後に、またも、Migration from STS Gradle to Buildship のダイアログが表示されたが、「OK」をクリックして進める。

手順2は、移行したいプロジェクトのパスを控えておきなさいとのことだけど、その気はないので、この手順は実施しない。
(手順2 Note the root module location of the project you want to migrate.)

手順3は、ワークスペースからプロジェクトをファイルを残して削除する、とのことなので、指示通りにする。

(手順3 Delete the projects from the workspace without physically removing them from the file system.)

プロジェクトを選択して、ポップアップメニューを表示して、「Delete」をクリック。

Delete project contents on disk [cannot be undone] はチェックせず、「OK」をクリック。

手順4から8は、元々あったプロジェクトをBuildshipに移行する手順であるが、今回それは行わないので、その次の手順のSTS Gradleのアンインストールを行う。
(手順4 Open the Buildship import wizard and specify the root project location.
Optionally set the advanced options (Gradle version, JVM argument, etc.) and check the project import preview.
手順5 Click Finish to execute the import.
手順6 When prompted, choose Overwrite Eclipse descriptors to perform a clean import, or choose the Keep option to preserve the plugin configuration.
手順7 Disable the hidden file filter in the Project/Package Explorer view.
手順8 For all projects, delete the .settings/gradle folder (it contains configuration data from STS Gradle).)

STS Gradleのアンインストールの手順は次のとおり。

これも、Migration guide from STS Gradle to Buildship のサイトに書いてある。

メニューバーの「Spring Tool Suite」-「Spring Tool Suiteについて」をクリック。

「Installation Details」をクリック。

「Installed Software」タブの「Gradle IDE」をクリック。

「Finish」をクリック。

Gradle IDEのアンインストールを反映させるためにSpring Tool Suiteの再起動が促されるので「Restart Now」をクリック。これで終わり。

MacにTensorFlowの環境構築

最近、会社でAIを業務に活用できないかという観点で、AIのAPIやAIライブラリのTensorFlowを確認している。
会社のMacにはもちろん、TensorFlowをインストールしている。
そんで、自宅MacにもTensorFlowの環境を構築することにした。

参考にしたサイトは次の通り。
Python3 TensorFlow for Mac 環境構築

ちなみにボクのmacOSは、10.13.4(macOS High Sierra)。
実施した手順は次から。
全てターミナルでコマンド入力。

1. Xcode Command Line tools

xcode-select --install
xcode-select: note: install requested for command line developer tools

2. Homebrewは以前にインストールしているので、homebrewからpyenvをインストール。

brew install pyenv

brew install pyenv

==> Caveats
A CA file has been bootstrapped using certificates from the SystemRoots
keychain. To add additional certificates (e.g. the certificates added in
the System keychain), place .pem files in
  /usr/local/etc/openssl/certs

and run
  /usr/local/opt/openssl/bin/c_rehash

This formula is keg-only, which means it was not symlinked into /usr/local,
because Apple has deprecated use of OpenSSL in favor of its own TLS and crypto libraries.

If you need to have this software first in your PATH run:
  echo 'export PATH="/usr/local/opt/openssl/bin:$PATH"' >> ~/.bash_profile

For compilers to find this software you may need to set:
    LDFLAGS:  -L/usr/local/opt/openssl/lib
    CPPFLAGS: -I/usr/local/opt/openssl/include

This formula is keg-only, which means it was not symlinked into /usr/local,
because macOS provides the BSD libedit library, which shadows libreadline.
In order to prevent conflicts when programs look for libreadline we are
defaulting this GNU Readline installation to keg-only..

Unversioned symlinks `python`, `python-config`, `pip` etc. pointing to
`python3`, `python3-config`, `pip3` etc., respectively, have been installed into
  /usr/local/opt/python/libexec/bin

If you need Homebrew's Python 2.7 run
  brew install python@2

Pip, setuptools, and wheel have been installed. To update them run
  pip3 install --upgrade pip setuptools wheel

You can install Python packages with
  pip3 install 
They will install into the site-package directory
  /usr/local/lib/python3.6/site-packages
