GradleのマルチプロジェクトでJavaDocを一箇所にまとめて出力する
$ gradle init --type java-library
でいくつかプロジェクトを作って階層構造に並べなおす。

Spring Boot でプロパティファイルを外部ファイル化する
プロパティファイルを外部ファイル化したい。
さらにファイル名に application.properties は使えないという条件。
Application.java
package hello; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.boot.CommandLineRunner; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.context.MessageSource; @SpringBootApplication public class Application implements CommandLineRunner { @Autowired GreedInterface greedInterface; @Autowired MessageSource messageSource; public static void main(String[] args) throws Exception { SpringApplication application = new SpringApplication(Application.class); application.setShowBanner(false); application.run(args); } @Override public void run(String... args) throws Exception { System.out.println(greedInterface.greed()); } }
GreedInterface.java
package hello; public interface GreedInterface { public String greed(); }
HelloService.java
package hello.impl; import hello.GreedInterface; import org.springframework.beans.factory.annotation.Value; import org.springframework.context.annotation.PropertySource; import org.springframework.stereotype.Service; @PropertySource("${spring.config.basepath}") @Service public class HelloService implements GreedInterface { @Value("${message}") private String message; @Override public String greed() { return message; } }
src/main/resources/default.properties
message=default
../../override/override.properties
message=override
jar実行
$ java -jar spring-boot-value-0.1.0.jar --spring.config.basepath=classpath:default.properties default
jar実行
$ java -jar spring-boot-value-0.1.0.jar --spring.config.basepath=file:../override/override.properties override
Sprig BootでProfile切り替え
Springの起動引数でBeanを切り替えたい
切り替え対象のBeanが実装するインターフェース
package hello; public interface GreedInterface { public String greed(); }
実装クラス。@Profileアノテーションで切り替えに使うプロファイル名を指定する。
package hello.impl; import org.springframework.context.annotation.Profile; import org.springframework.stereotype.Service; import hello.GreedInterface; @Profile("hello") @Service public class HelloService implements GreedInterface { @Override public String greed() { return "hello"; } }
package hello.impl; import org.springframework.context.annotation.Profile; import org.springframework.stereotype.Service; import hello.GreedInterface; @Profile("hi") @Service public class HiService implements GreedInterface { @Override public String greed() { return "Hi"; } }
呼び出し側のメインクラス。GreedInterfaceをAutowireする。
package hello; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.boot.CommandLineRunner; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; @SpringBootApplication public class Application implements CommandLineRunner { @Autowired GreedInterface greedInterface; public static void main(String[] args) throws Exception { SpringApplication application = new SpringApplication(Application.class); application.setShowBanner(false); application.run(args); } @Override public void run(String... args) throws Exception { System.out.println(greedInterface.greed()); } }
application.propertiesにデフォルトのプロファイル名を指定する。
spring.profiles.active=hello
実行時に起動引数でプロファイルを変える。
$ java -jar gs-spring-boot-0.1.0.jar --spring.profiles.active=hi Hi $ java -jar gs-spring-boot-0.1.0.jar --spring.profiles.active=hello hello
exportする環境変数をファイル経由で読み込む
環境
- Ubuntu 14.04
やりたいこと
- シェルを実行するときにexportする環境変数を別ファイルにする
- 別ファイルはシェルで動的に生成する
動的にexport文を作るシェルは割愛
出力イメージ
send.txt
export HOGE_PATH='send_path' export HOGE_NAME='send_name'
受け取る側の親シェル
root.sh
#!/bin/bash export FILE_PATH=send.txt ./receive.sh
受け取ったことを確認するシェル
receive.sh
#!/bin/bash
. ${FILE_PATH}
echo ${HOGE_PATH}
echo ${HOGE_NAME}

touch ./test/hello
}
# テスト結果の整理。リダイレクトしたファイルを削除する。
tearDown() {

}
# テスト対象スクリプトを読み込む
. first.sh
# テスト関数。testを名称の初めにつける。
testHelloWorld() {
# テスト対象を読んでリダイレクトする
helloWorld > ./test/hello
# 関数の戻りが0であることを確認する

# 出力結果を変数に入れる
