使用 JPA 在 java SpringBoot 上通过 JNDI 连接两个数据库

问题描述 投票：0回答：3

我有这个问题。 3天。 当我尝试使用 Maven 构建应用程序时，我遇到了这个问题，但我的构建成功了，然后当我在 WebLogic 上部署并调用任何端点时，此响应给我一个 500 内部服务器错误。

这是我的DataSourceConfig

import javax.sql.DataSource;

import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.boot.jdbc.DataSourceBuilder;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Primary;


    @Configuration
    public class DataSourceConfig {
         
            @Bean(name = "primaryDataSource",destroyMethod = "")
            @Primary
            @ConfigurationProperties("spring.datasource.primary")
            public DataSource firstDataSource(){
                return DataSourceBuilder.create().build();
            }
    
            @Bean(name = "secondaryDataSource",destroyMethod = "")
            @ConfigurationProperties("spring.datasource.secondary")
            public DataSource secondDataSource(){
                return DataSourceBuilder.create().build();
            }
            
    
    }

        HashMap<String, Object> properties = new HashMap<>();
        properties.put("hibernate.hbm2ddl.auto", env.getProperty("hibernate.hbm2ddl.auto"));

        em.setJpaPropertyMap(properties);

    }

    @Primary
    @Bean

        DriverManagerDataSource dataSource = new DriverManagerDataSource();
        dataSource.setUrl(env.getProperty("spring.datasource.primary.jndi-name"));

        return dataSource;
    }

    @Primary

    public PlatformTransactionManager localTransactionManager() {

        JpaTransactionManager transactionManager = new JpaTransactionManager();
        transactionManager.setEntityManagerFactory(localEntityManager().getObject());
        return transactionManager;

这是我的 weblogic JNDI。 webLogic jndi

我尝试了所有方法..但无法解决。请我需要一些帮助。谢谢！

#Base de datos LOCAL 
spring.datasource.primary.driver-class-name=oracle.jdbc.OracleDriver 
spring.datasource.primary.jndi-name=jdbc/differenceload 
#Base de datos FACTURADOR 
spring.datasource.secondary.jndi-name=jdbc/facturador 
spring.datasource.secondary.driver-class-name=oracle.jdbc.OracleDriver
java spring weblogic jndi

快速查看并在文件中进行一些更改。

应用程序属性

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

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;
        }
    }
}

您需要从 jndi 查找数据源，而不是使用 

DataSourceBuilder
创建数据源。你可以这样做...

@Configuration
public class WeblogicResourceConfig {

    private static final Logger log = LoggerFactory.getLogger(WeblogicResourceConfig.class);

    @Autowired
    private Environment env;

    @Bean
    public JndiTemplate jndiTemplate() {
        Properties props = new Properties();
        props.put(Context.INITIAL_CONTEXT_FACTORY, "weblogic.jndi.WLInitialContextFactory");
        return new JndiTemplate(props);
    }

    // destroyMethod MUST be blank or datasource is removed from jndi tree on
    // see https://github.com/spring-projects/spring-framework/issues/17153
    @Bean(destroyMethod = "")
    @Primary
    public DataSource primaryDataSource() throws NamingException {
        return (DataSource) jndiTemplate().lookup(env.getProperty("spring.datasource.primary.jndi-name"));
    }


    // destroyMethod MUST be blank or datasource is removed from jndi tree
    // see https://github.com/spring-projects/spring-framework/issues/17153
    @Bean(destroyMethod = "")
    public DataSource secondaryDataSource() throws NamingException {
        return (DataSource) jndiTemplate().lookup(env.getProperty("spring.datasource.secondary.jndi"));
    }
}

创建

LocalContainerEntityManagerFactoryBean
时，注入上面的那些数据源，而不是创建新的数据源bean。

最后问题出在我的 WebLogic 本地配置中。我真的不知道出了什么问题，但我的伙伴在他的环境中尝试并且确实有效！

谢谢。我关闭它是因为我不记得我的 WebLogic 配置中的错误在哪里。

致以诚挚的问候！
