使用JNDI在Spring Boot中配置多个DataSource
我想使用您的Application Server内置功能管理多个 DataSource，并使用JNDI访问它。我正在使用带有Spring JPA数据的Spring启动。
I want to manage mutiple DataSource using your Application Servers built-in features and access it using JNDI. I am using Spring boot with Spring JPA data.
我可以为单个数据源配置application.properties： -
I am able to configure the application.properties for single datasource:-
spring.datasource.jndi-name=jdbc/customers
我在context.xml文件中的配置如下： -
And my configuration in context.xml file as below:-
<Resource name="jdbc/customer" auth="Container" type="javax.sql.DataSource"
maxTotal="100" maxIdle="30" maxWaitMillis="10000"
username="root" password="root" driverClassName="com.mysql.jdbc.Driver"
url="jdbc:mysql://localhost:3306/customer"/>
一切正常。
但是当我无法配置两个数据源。
But when I am unable to configure for two datasource.
我确信context.xml文件中的配置： -
I am sure on the configuration in context.xml file:-
<Resource name="jdbc/customer" auth="Container" type="javax.sql.DataSource"
maxTotal="100" maxIdle="30" maxWaitMillis="10000"
username="root" password="root" driverClassName="com.mysql.jdbc.Driver"
url="jdbc:mysql://localhost:3306/customer"/>
<Resource name="jdbc/employee" auth="Container" type="javax.sql.DataSource"
maxTotal="100" maxIdle="30" maxWaitMillis="10000"
username="root" password="root" driverClassName="com.mysql.jdbc.Driver"
url="jdbc:mysql://localhost:3306/employee"/>
我对application.properties文件配置有疑问。
我尝试了以下选项但没有成功： -
I tried the below options with no success:-
spring.datasource.jndi-name=jdbc/customers,jdbc/employee
请告诉我有关Spring启动的任何详细信息使用JNDI获取多个数据源。我好几天都在寻找这种配置。任何形式的建议或评论都会受到高度赞赏。
Please let me know any details on Spring boot with JNDI for mutiple data source. I was looking for this configuration for days now. Any kind of suggestion or comments is hight appreciated.
第二次试用按 Spring Boot Documentation
spring.datasource.primary.jndi-name=jdbc/customer
spring.datasource.secondary.jndi-name=jdbc/project
配置类。
@Bean
@Primary
@ConfigurationProperties(prefix="datasource.primary")
public DataSource primaryDataSource() {
return DataSourceBuilder.create().build();
}
@Bean
@ConfigurationProperties(prefix="datasource.secondary")
public DataSource secondaryDataSource() {
return DataSourceBuilder.create().build();
}
应用程序无法启动。虽然tomcat服务器正在启动。日志中不会打印错误。
The application does not get started. Though the tomcat server is getting started. No errors are printed in the log.
第三次审判： - 使用JndiObjectFactoryBean
我有以下application.properties
I have the below application.properties
spring.datasource.primary.expected-type=javax.sql.DataSource
spring.datasource.primary.jndi-name=jdbc/customer
spring.datasource.primary.jpa.database-platform=org.hibernate.dialect.MySQL5Dialect
spring.datasource.primary.jpa.show-sql=false
spring.datasource.primary.jpa.hibernate.ddl-auto=validate
spring.datasource.secondary.jndi-name=jdbc/employee
spring.datasource.secondary.expected-type=javax.sql.DataSource
spring.datasource.secondary.jpa.database-platform=org.hibernate.dialect.MySQL5Dialect
spring.datasource.secondary.jpa.show-sql=false
spring.datasource.secondary.jpa.hibernate.ddl-auto=validate
以及下面的java配置： -
And the below java configuration:-
@Bean(destroyMethod="")
@Primary
@ConfigurationProperties(prefix="spring.datasource.primary")
public FactoryBean primaryDataSource() {
return new JndiObjectFactoryBean();
}
@Bean(destroyMethod="")
@ConfigurationProperties(prefix="spring.datasource.secondary")
public FactoryBean secondaryDataSource() {
return new JndiObjectFactoryBean();
}
但仍然收到错误： -
But still getting error:-
Related cause: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'primaryDataSource' defined in class path resource [com/web/initializer/MvcConfig.class]: Invocation of init method failed; nested exception is javax.naming.NameNotFoundException: Name [jdbc/customer] is not bound in this Context.

更新： -
使用以下属性文件进行试用： -
Update:- Trial using the below properties file:-
spring.datasource.primary.expected-type=javax.sql.DataSource
spring.datasource.primary.jndi-name=java:comp/env/jdbc/customer
spring.datasource.secondary.jndi-name=java:comp/env/jdbc/employee
spring.datasource.secondary.expected-type=javax.sql.DataSource
spring.jpa.database-platform=org.hibernate.dialect.MySQL5Dialect
spring.jpa.show-sql=false
spring.jpa.hibernate.ddl-auto=validate
它创建了客户架构中的所有表，但也未能尝试查找其他表。（来自第二个架构）
It creates all the tables in customer schema , but fails trying to find the other tables also.(from the second schema)
这是您的第三次试用的解决方案稍作修改。
考虑这个解决方案（Spring Boot 1.3.2）：
This is the solution for your third trial a little bit modified. Consider this solution (Spring Boot 1.3.2):
application.properties文件：
application.properties file:
spring.datasource.primary.jndi-name=java:/comp/env/jdbc/SecurityDS
spring.datasource.primary.driver-class-name=org.postgresql.Driver
spring.datasource.secondary.jndi-name=java:/comp/env/jdbc/TmsDS
spring.datasource.secondary.driver-class-name=org.postgresql.Driver
spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.PostgreSQL9Dialect
spring.jpa.show-sql=false
配置：
@Configuration@ EnableConfigurationProperties
public class AppConfig {
@Bean@ ConfigurationProperties(prefix = "spring.datasource.primary")
public JndiPropertyHolder primary() {
return new JndiPropertyHolder();
}
@Bean@ Primary
public DataSource primaryDataSource() {
JndiDataSourceLookup dataSourceLookup = new JndiDataSourceLookup();
DataSource dataSource = dataSourceLookup.getDataSource(primary().getJndiName());
return dataSource;
}
@Bean@ ConfigurationProperties(prefix = "spring.datasource.secondary")
public JndiPropertyHolder secondary() {
return new JndiPropertyHolder();
}
@Bean
public DataSource secondaryDataSource() {
JndiDataSourceLookup dataSourceLookup = new JndiDataSourceLookup();
DataSource dataSource = dataSourceLookup.getDataSource(secondary().getJndiName());
return dataSource;
}
private static class JndiPropertyHolder {
private String jndiName;
public String getJndiName() {
return jndiName;
}
public void setJndiName(String jndiName) {
this.jndiName = jndiName;
}
}
}
然后你可以按照指南 http：// docs .spring.io / spring-data / jpa / docs / 1.3.0.RELEASE / reference / html / jpa.repositories.html 将您的数据源与jpa存储库一起使用。
And then you can follow guide http://docs.spring.io/spring-data/jpa/docs/1.3.0.RELEASE/reference/html/jpa.repositories.html to use your datasources with jpa repositories.
