Konfigurieren von zwei Datenquellen durch jndi Nachschlagen mit Springboot

2017-01-30 3 views

Ich habe eine kleine Webanwendung mit Spring Boot erstellt, die zwei Datenquellen hat (eine für die Anwendungsdaten und eine für das Abrufen von Benutzerzugriffsinformationen). Ich habe dies erfolgreich konfiguriert, indem ich eine config-Klasse für jede Datenquelle verwendete und Verbindungsdetails für Datenquellen in der Datei application.properties verwendete.Konfigurieren von zwei Datenquellen durch jndi Nachschlagen mit Springboot

Ich versuche jetzt, dies umzuformatieren, um jndi lookup für die Datenquellendetails zu verwenden, so dass ich den gleichen Ansatz lokal verwenden kann, wie ich in dev/test und prod verwenden werde.

Ich habe meine Datenbank-Konfigurationsklassen so geändert, dass sie jndi lookup verwenden und meine App jetzt auf dem Pivotal tc Server in der Spring Tool Suite ausführen.

Derzeit kann ich sehen, dass eine der Datenquellen korrekt konfiguriert ist (ich gebe eine Datensatzanzahl aus einer Tabelle beim Start der Anwendung zurück). Jedoch meine zweite Datenquelle scheint nicht richtig konfiguriert werden, und ich bekomme eine Ausnahme ...

Meine application.properties Datei hat die folgenden Eigenschaften

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

Meine Datenbank Konfigurationsklassen wie folgt aussehen.

. 
@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; 
    } 
}

Kann jemand sehen, warum meine zweite Datenquelle nicht konfiguriert wird? Ist dies ein Life-Cycle-Timing-Problem? Wie sage ich die primäre Datenquelle richtig konfiguriert aber die Sicherheit nicht ein

aktualisiert

Die JndiPropertyHolder Komfort-Klasse wie unten

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; 
    } 

}

können Sie bitte erwähnen Die Referenz von 'JndiPropertyHolder' Klasse? Ich kann keinen Import für die Auflösung finden. –

Beachten Sie die Klasse Config in über Code-Schnipsel, hat es mit @Configuration kommentiert worden und einer der Datenquellen in ihm als @Primary

//GreetingController.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; 
//import org.springframework.jdbc.core.JdbcTemplate; 
//import org.springframework.web.bind.annotation.RequestMapping; 
//import org.springframework.web.bind.annotation.RequestParam; 
//import org.springframework.web.bind.annotation.RestController; 
// 
//import hello.Application.Config; 
// 
//@RestController 
public class GreetingController { 

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

    @Autowired 
    Config conf; 

    @RequestMapping("/greeting") 
    public Greeting greeting(@RequestParam(value = "name", defaultValue = "World") String name) { 
     String ss = null; 
     List<Map<String, Object>> a = new JdbcTemplate(conf.secondaryDs()) 
       .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("/") 
    public Greeting greetingBlank() throws Exception { 
     String ss = null; 
     List<Map<String, Object>> a = new JdbcTemplate(conf.primaryDs()).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)); 
    } 
}

nun also in einen meiner Ruhe Controller erklärt in GreetingController Klasse Ich kann sicher die @Autowired Config Config Instanz verwenden. So können wir new JdbcTemplate(conf.secondaryDs()) für die Abfrage der Datenbank verwenden, die von der sekundären Datenquelle referenziert wird. OR new JdbcTemplate(conf.primaryDs()) für die Datenbank, die von der primären Datenquelle bezeichnet Abfrage

** Gleiche kann durch Konfiguration JdbcTemplates in Application.class erreicht werden, denn dies ist die Klasse ConfigJdbcTemplates beobachten in Application.java.Bitte haben Sie einen Blick auf unten Implementierung in Controller 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; 
//import org.springframework.web.bind.annotation.RequestMapping; 
//import org.springframework.web.bind.annotation.RestController; 
// 
//import hello.Application.ConfigJdbcTemplates; 
// 
//@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)); 
    } 
}

Erwartungen Beide oben genannten Methoden arbeiten gemäß der einzige Unterschied besteht darin, dass bei der ersten Implementierung ich autowiring Datenquellen und in der zweiten Implementierung Jdbctemplate ist Autowired.

Meine application.properties Datei ist als unten

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

Diese Anwendung auf Jboss eap 6.4, wo die jndi-Namen gebunden sind, mit Datasource Details von Jboss eingesetzt wird standalone.xml
