在网上快速搜索会显示3或4个变体如何在persistence.xml中指定xmlns和xsi:schemaLocation。
指定JPA 2.1版的“正确”方式是什么?
我在用着:
<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">
根据
official documentation它必须(像你的):
