Question

我全局设置了CATALINA_HOME属性（在.profile中）。

BJs-Mac-Pro:server bjpeterdelacruz$ echo $CATALINA_HOME
/Users/bjpeterdelacruz/apache-tomcat-8.0.30

在persistence.xml文件中，我有以下配置：

<?xml version="1.0" encoding="UTF-8"?>
<persistence version="2.0" xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd">
<persistence-unit name="jpa-test" transaction-type="RESOURCE_LOCAL">
<provider>org.eclipse.persistence.jpa.PersistenceProvider</provider>
<class>com.bpd.rest.Department</class>
<properties>
  <property name="javax.persistence.jdbc.driver" value="org.sqlite.JDBC" />
  <property name="javax.persistence.jdbc.url" value="jdbc:sqlite:/${catalina.home}/webapps/server/WEB-INF/classes/hr.db" />
  <property name="eclipselink.ddl-generation" value="drop-and-create-tables" />
  <property name="eclipselink.ddl-generation.output-mode" value="database" />
</properties>
</persistence-unit>
</persistence>

但是，当我转到URL时，我收到以下异常：

Exception [EclipseLink-4002] (Eclipse Persistence Services - 2.6.2.v20151217-774c696): org.eclipse.persistence.exceptions.DatabaseException
Internal Exception: java.sql.SQLException: path to '/${catalina.home}/webapps/server/WEB-INF/classes/hr.db': '/${catalina.home}' does not exist
Error Code: 0

如果我硬编码hr.db文件的路径，一切都很好，但我不想硬编码。

如何解决此错误，即设置catalina.home？
我可以通过Gradle或属性文件传递路径吗？

您需要删除斜杠，因此网址如下所示：

jdbc:sqlite:${catalina.home}/webapps/server/WEB-INF/classes/hr.db

另见本讨论：

Relative path to SQLite DB in context.xml

'/$ {catalina.home}'不存在 - 如何修复此错误？
