【问题描述】：

这是我的persistence.xml 的样子

<?xml version="1.0" encoding="UTF-8"?>
<persistence
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xmlns="http://java.sun.com/xml/ns/persistence"
        xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd"
        version="2.0">
    <persistence-unit name="earth">
        <provider>org.hibernate.jpa.HibernatePersistenceProvider</provider>
        <jta-data-source>java:/jdbc/EarthDS</jta-data-source>
        <properties>
            <property name="hibernate.archive.autodetection" value="class"/>
            <property name="hibernate.id.new_generator_mappings" value="true"/>
            <property name="javax.persistence.lock.timeout" value="5000"/>
        </properties>
    </persistence-unit>
</persistence>

我正在使用maven-cargo-plugin 部署war 文件。根据他们的documentation，他们将JNDI的数据源设置为

        <configuration>
          <properties>
            <cargo.datasource.datasource.derby>
                cargo.datasource.driver=org.apache.derby.jdbc.EmbeddedDriver|
                cargo.datasource.url=jdbc:derby:derbyDB;create=true|
                cargo.datasource.jndi=jdbc/CargoDS|
                cargo.datasource.username=APP|
                cargo.datasource.password=nonemptypassword
            </cargo.datasource.datasource.derby>
          </properties>
        </configuration>

由于我使用的是H2数据库，所以我将其设置为

                      <properties>
                           <cargo.servlet.port>9090</cargo.servlet.port>
                           <properties>
                                <cargo.datasource.datasource>
                                     cargo.datasource.driver=org.h2.Driver|
                                     cargo.datasource.url=jdbc:h2:~/earth;create=true|
                                     cargo.datasource.jndi=jdbc/EarthDS|
                                     cargo.datasource.username=sa|
                                     cargo.datasource.password=
                                </cargo.datasource.datasource>
                           </properties>
                      </properties>
                 </configuration>

当我运行项目时，我在日志中看到错误

有人可以帮我理解这里有什么不对吗？

谢谢

【参考方案1】：

在文档 sn-p 中，名称有 4 个部分 在您的示例中，它只有 3 个部分

既然 cargo 可以配置多个数据源，那么第 4 部分是否需要唯一标识它们？

【参考方案2】：

使用与 persistence.xml 中相同的 jndi 字符串，并在 jdbc 字符串中指定 file 或 mem：

<cargo.datasource.datasource.h2>
    cargo.datasource.jndi=java:/jdbc/EarthDS|
    cargo.datasource.driver=org.h2.Driver|
    cargo.datasource.url=jdbc:h2:mem:earth;create=true|
    cargo.datasource.username=sa|
    cargo.datasource.password=sa
</cargo.datasource.datasource.h2>

确保容器具有对 h2 驱动程序的依赖项：

<container>
    ...
    <dependencies>
        <dependency>
            <groupId>com.h2database</groupId>
            <artifactId>h2</artifactId>
        </dependency>
    </dependencies>
</container>

并且 h2 驱动程序列在 maven 依赖项中：

<dependencies>
    ...
    <dependency>
        <groupId>com.h2database</groupId>
        <artifactId>h2</artifactId>
        <version>1.4.182</version>
    </dependency>
</dependencies>
