java - Wildfly 数据源与 DefaultDS 冲突

coder 2024-03-05 原文

我从 jboss 7.1 迁移到 wildfly，我的数据源出现了一些问题。

当我查看我的日志时，我看到 wildfly 部署了我的骰子数据源并将其绑定(bind)到 [java:/jdbc/dice]。它在我的持久性 xml 中被引用。

<?xml version="1.0" encoding="UTF-8"?>
<persistence version="2.1"
    xmlns="http://xmlns.jcp.org/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/persistence http://xmlns.jcp.org/xml/ns/persistence/persistence_2_1.xsd">
    <persistence-unit name="dice">
        <provider>org.hibernate.ejb.HibernatePersistence</provider>
        <jta-data-source>jdbc/dice</jta-data-source>

现在我想在启动时检查一些数据源设置以确保隔离级别等:

@Singleton
@Startup
public class ConfigService {
    @Resource(name = "java:/jdbc/dice")
    private DataSource dataSource;

在启动方法中我只是做这样的事情:

        Connection connection = dataSource.getConnection();
        boolean autoCommit = connection.getAutoCommit();
        int isolationLevel = connection.getTransactionIsolation();

在启动时我总是得到:

如果我更改数据源注入(inject)的 jndi 名称，它会起作用(例如，仅限骰子)，但我不明白为什么。我做错了什么？

问候， 米

最佳答案 

@Resource(lookup = "java:jboss/datasources/dice")
private DataSource dataSource;

我误用了@Resource 注释并使用了名称而不是查找。 (切换 jndi 名称只是为了测试。以防万一)
