本文整理了Java中javax.jcr.Node.addNode()方法的一些代码示例，展示了Node.addNode()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Node.addNode()方法的具体详情如下：
包路径：javax.jcr.Node
类名称：Node
方法名：addNode

Node.addNode介绍

[英]Creates a new node at relPath.

This is session-write method, meaning that the addition of the new node is dispatch upon Session#save.

The relPath provided must not have an index on its final element, otherwise a Repository

If ordering is supported by the node type of the parent node of the new node then the new node is appended to the end of the child node list.

The new node's primary node type will be determined by the child node definitions in the node types of its parent. This may occur either immediately, on dispatch (save, whether within or without transactions) or on persist (save without transactions, commit within a transaction), depending on the implementation.

An ItemExistsException will be thrown either immediately, on dispatch (save, whether within or without transactions) or on persist (save without transactions, commit within a transaction), if an item at the specified path already exists and same-name siblings are not allowed. Implementations may differ on when this validation is performed.

A PathNotFoundException will be thrown either immediately, on dispatch (save, whether within or without transactions) or on persist (save without transactions, commit within a transaction), if the specified path implies intermediary nodes that do not exist. Implementations may differ on when this validation is performed.

A ConstraintViolationException will be thrown either immediately, on dispatch (save, whether within or without transactions) or on persist (save without transactions, commit within a transaction), if adding the node would violate a node type or implementation-specific constraint or if an attempt is made to add a node as the child of a property. Implementations may differ on when this validation is performed.

A VersionException will be thrown either immediately, on dispatch (save, whether within or without transactions) or on persist (save without transactions, commit within a transaction), if the node to which the new child is being added is read-only due to a checked-in node. Implementations may differ on when this validation is performed.

A LockException will be thrown either immediately, on dispatch (save, whether within or without transactions) or on persist (save without transactions, commit within a transaction), if a lock prevents the addition of the node. Implementations may differ on when this validation is performed.
[中]在[$0$]处创建一个新节点。
这是会话写入方法，意味着新节点的添加是在会话#保存时分派。
提供的relPath不能在其最后一个元素上有索引，否则将创建一个存储库
如果新节点的父节点的节点类型支持排序，则新节点将附加到子节点列表的末尾。
新节点的主节点类型将由其父节点类型中的子节点定义确定。这可能会立即发生，在分派时（保存，无论是否包含事务）或在持久化时（保存而不包含事务，在事务中提交），具体取决于实现。
如果指定路径上的项目已存在且不允许同名同级，则在分派（保存，无论是否包含事务）或持久化（保存，不包含事务，在事务中提交）时会立即抛出ItemExistsException。执行此验证的时间可能会有所不同。
如果指定的路径暗示中间节点不存在，则在分派时（保存，无论是否包含事务）或在持久化时（保存而不包含事务，在事务中提交），将立即抛出PathNotFoundException。执行此验证的时间可能会有所不同。
如果添加节点会违反节点类型或特定于实现的约束，或者尝试将节点添加为属性的子级，则在分派（保存，无论是否包含事务）或持久化（保存，不包含事务，在事务中提交）时，会立即抛出ConstraintViolationException。执行此验证的时间可能会有所不同。
如果要添加新子节点的节点由于签入节点而为只读，则在分派（保存，无论是否包含事务）或持久化（保存，不包含事务，在事务中提交）时，会立即抛出VersionException。执行此验证的时间可能会有所不同。
如果锁阻止添加节点，则LockException将在分派时（保存，无论是否包含事务）或持久化时（保存而不包含事务，在事务中提交）立即抛出。执行此验证的时间可能会有所不同。
