本文整理了Java中javax.jcr.Session.exportSystemView()方法的一些代码示例，展示了Session.exportSystemView()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。Session.exportSystemView()方法的具体详情如下：
包路径：javax.jcr.Session
类名称：Session
方法名：exportSystemView

Session.exportSystemView介绍

[英]Serializes the node (and if noRecurse is false, the whole subgraph) at absPath as an XML stream and outputs it to the supplied OutputStream. The resulting XML is in the system view form. Note that absPath must be the path of a node, not a property.

If skipBinary is true then any properties of PropertyType.BINARY will be serialized as if they are empty. That is, the existence of the property will be serialized, but its content will not appear in the serialized output (the <sv:value> element will have no content). Note that in the case of multi-value BINARY properties, the number of values in the property will be reflected in the serialized output, though they will all be empty. If skipBinary is false then the actual value(s) of each BINARY property is recorded using Base64 encoding.

If noRecurse is true then only the node at absPath and its properties, but not its child nodes, are serialized. If noRecurse is false then the entire subgraph rooted at absPath is serialized.

If the user lacks read access to some subsection of the specified tree, that section simply does not get serialized, since, from the user's point of view, it is not there.

The serialized output will reflect the state of the current workspace as modified by the state of this Session. This means that pending changes (regardless of whether they are valid according to node type constraints) and all namespace mappings in the namespace registry, as modified by the current session-mappings, are reflected in the output.

The output XML will be encoded in UTF-8.

It is the responsibility of the caller to close the passed OutputStream.
[中]将absPath处的节点（如果noRecurse是false，则整个子图）序列化为XML流，并将其输出到提供的OutputStream。生成的XML是系统视图形式。请注意absPath必须是节点的路径，而不是属性。
如果skipBinary为真，则PropertyType.BINARY的任何属性都将被序列化，就像它们是空的一样。也就是说，属性的存在将被序列化，但其内容不会出现在序列化的输出中（<sv:value>元素将没有内容）。请注意，在多值BINARY属性的情况下，属性中的值数将反映在序列化输出中，尽管它们都是空的。如果skipBinary为false，则使用Base64编码记录每个BINARY属性的实际值。
如果noRecurse为true，则只序列化absPath处的节点及其属性，而不序列化其子节点。如果noRecurse为false，则以absPath为根的整个子图将被序列化。
如果用户缺乏对指定树的某个子部分的读取权限，该部分就不会被序列化，因为从用户的角度来看，它不在那里。
序列化输出将反映当前工作区的状态，该状态由该Session的状态修改。这意味着挂起的更改（无论根据节点类型约束这些更改是否有效）和命名空间注册表中由当前会话映射修改的所有命名空间映射都会反映在输出中。
输出XML将以UTF-8编码。
来电者有责任关闭已通过的OutputStream。
