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

Query.getParameters介绍

[英]Get the parameter objects corresponding to the declared parameters of the query. Returns empty set if the query has no parameters. This method is not required to be supported for native queries.
[中]获取与查询的已声明参数相对应的参数对象。如果查询没有参数，则返回空集。本机查询不需要支持此方法。

private boolean registerExcessParameters(Query query) {
  // DATAJPA-1172
  // Since EclipseLink doesn't reliably report whether a query has parameters
  // we simply try to set the parameters and ignore possible failures.
  // this is relevant for native queries with SpEL expressions, where the method parameters don't have to match the
  // parameters in the query.
