Springbootでjndiルックアップで2つのデータソースを設定する

Question

Springブートで構築された小さなアプリケーションで、アプリケーションデータ用とユーザアクセス情報取得用の2つのデータソースがあります。これは、各データソースのconfigクラスを使用し、application.propertiesファイルのデータソース接続の詳細を使用して正常に設定しました。

私はdev/testとprodで使用するのと同じアプローチをローカルで使用できるように、これをリファクタリングしてデータソースの詳細のjndiルックアップを使用しようとしています。

jndiルックアップを使用するようにデータベースコンフィグレーションクラスを修正し、Spring Tool Suiteで提供されるPivotal tcサーバーでアプリケーションを実行しています。

現在、データソースの1つが正しく設定されていることがわかります（アプリケーションの起動時にテーブルからレコード数を返します）。しかし

マイapplication.propertiesファイルが

spring.datasource.jndi-name=java:comp/env/jdbc/app_datasource 
spring.datasource.expected-type=javax.sql.DataSource 

security.datasource.jndi-name=java:comp/env/jdbc/security_datasource 
security.datasource.expected-type=javax.sql.DataSource 

私のデータベース・コンフィギュレーション・クラスは次のようになり、次のプロパティがあり...私の第二のデータソースが正しく設定を取得するためには表示されませんし、私は例外を取得します。 。

@Configuration 
@EnableConfigurationProperties 
@EnableAutoConfiguration(exclude = {DataSourceAutoConfiguration.class, DataSourceTransactionManagerAutoConfiguration.class}) 
public class AppDBConfig { 

    @Bean 
    @ConfigurationProperties(prefix = "spring.datasource") 
    public JndiPropertyHolder primary() { 
     return new JndiPropertyHolder(); 
    } 

    @Bean(name = "app") 
    @Primary 
    public DataSource appDataSource() { 
     JndiDataSourceLookup dataSourceLookup = new JndiDataSourceLookup(); 
     DataSource dataSource = dataSourceLookup.getDataSource(primary().getJndiName()); 
     return dataSource; 
    } 
} 

@Configuration 
@EnableConfigurationProperties 
@EnableAutoConfiguration(exclude = {DataSourceAutoConfiguration.class, DataSourceTransactionManagerAutoConfiguration.class}) 
public class SecurityDBConfig { 

    @Bean 
    @ConfigurationProperties(prefix = "security.datasource") 
    public JndiPropertyHolder security() { 
     return new JndiPropertyHolder(); 
    } 

    @Bean(name = "security") 
    public DataSource securityDataSource() { 
     JndiDataSourceLookup dataSourceLookup = new JndiDataSourceLookup(); 
     DataSource dataSource = dataSourceLookup.getDataSource(security().getJndiName()); 
     return dataSource; 
    } 
} 

とserver.xmlには、この

のように見えます

私の2番目のデータソースが設定されない理由は誰にも見えますか？これはライフサイクルのタイミングの問題ですか？私は、プライマリデータソースが正しく設定されますが、私は私の春を構成することによって成功し、これを達成した

import org.springframework.stereotype.Component; 

@Component 
public class JndiPropertyHolder { 
    private String jndiName; 

    public String getJndiName() { 
     return this.jndiName; 
    } 

    public void setJndiName(final String jndiName) { 
     this.jndiName = jndiName; 
    } 

} 

Answer 1

以下のように、1つは

として宣言されていますGreetingControllerクラス私は安全に@Autowired Config設定インスタンスを使用できます。つまり、new JdbcTemplate(conf.secondaryDs())を使用して、セカンダリデータソースによって参照されるデータベースをクエリできます。これはクラスConfigJdbcTemplates Application.javaでを観察するためまたはプライマリデータソース

で呼ばデータベースを照会するためnew JdbcTemplate(conf.primaryDs()) **は同じことが、Application.classでJdbcTemplatesを構成することによって達成することができます。上記の方法の両方が期待どおりに動作している唯一の違いは、最初の実装では、私がデータソースをオートワイヤリングし、第2の実施JdbctemplateによということであるコントローラDatabasePrimaryQueryController

//DatabasePrimaryQueryController.java 
//package hello; 
// 
//import java.util.List; 
//import java.util.Map; 
//import java.util.Set; 
//import java.util.concurrent.atomic.AtomicLong;

//import org.springframework.beans.factory.annotation.Autowired;

//@RestController 
public class DatabasePrimaryQueryController { 

    private static final String template = "Hello, %s!"; 
    private final AtomicLong counter = new AtomicLong(); 

    @Autowired 
    ConfigJdbcTemplates confJts; 

    @RequestMapping("/queryforpas") 
    public Greeting greeting() throws Exception { 
     String ss = null; 
     List<Map<String, Object>> a = confJts.secondaryJT() 
       .queryForList("SELECT * from secondaryDB"); 
     for (Map<String, Object> map : a) { 
      Set<String> kkeys = map.keySet(); 
      for (String string : kkeys) { 
       if (map.get(string) != null) 
        ss += string + " -- " + map.get(string).toString() + "## "; 
      } 
     } 
     return new Greeting(counter.incrementAndGet(), String.format(template, ss)); 
    } 

    @RequestMapping("/queryforods") 
    public Greeting greetingBlank() throws Exception { 
     String ss = null; 
     List<Map<String, Object>> a = confJts.primaryJT().queryForList(
       "SELECT * from primaryDB"); 
     for (Map<String, Object> map : a) { 
      Set<String> kkeys = map.keySet(); 
      for (String string : kkeys) { 
       if (map.get(string) != null) 
        ss += string + " -- " + map.get(string).toString() + "## "; 
      } 
     } 
     return new Greeting(counter.incrementAndGet(), String.format(template, ss)); 
    } 
} 

で実装以下を見てください。 Autowiredです。このアプリケーションは、JNDI-名はJBossのからのデータソースの詳細はバインドされたJBoss EAP 6.4に配備されている

server.servlet-path=/* 
server.port=7877 
foo.spring.datasource.jndi-name=java:/PrimaryDB 
bar.spring.datasource.jndi-name=java:/SecondaryDB 

以下のよう
