本文整理了Java中org.mongodb.morphia.query.Query.filter方法的一些代码示例，展示了Query.filter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.filter方法的具体详情如下：
包路径：org.mongodb.morphia.query.Query
类名称：Query
方法名：filter

Query.filter介绍

[英]Create a filter based on the specified condition and value.

Note: Property is in the form of "name op" ("age >").

Valid operators are ["=", "==","!=", "<>", ">", "=", "

Examples:

  • filter("yearsOfOperation >", 5)
  • filter("rooms.maxBeds >=", 2)
  • filter("rooms.bathrooms exists", 1)
  • filter("stars in", new Long[]{3, 4}) //3 and 4 stars (midrange?)}
  • filter("quantity mod", new Long[]{4, 0}) // customers ordered in packs of 4)}
  • filter("age >=", age)
  • filter("age =", age)
  • filter("age", age) (if no operator, = is assumed)
  • filter("age !=", age)
  • filter("age in", ageList)
  • filter("customers.loyaltyYears in", yearsList)

You can filter on id properties if this query is restricted to a Class.
[中]根据指定的条件和值创建筛选器。
注：物业的形式为“名称op”（“年龄>”）。
有效运算符为[“=”、“=”、“！=”、“<>”、“>”、“=”、”
例如：
*过滤器（“yearsOfOperation>”，5）
*过滤器（“rooms.maxBeds>=”，2）
*过滤器（“房间。浴室存在”，1）
*过滤器（“星在”，新长[]{3，4}）//3和4星（中程？}
*过滤器（“数量模式”，新长[]{4，0}）//客户以4个包装订购）
*过滤器（“年龄>=”，年龄）
*过滤器（“age=，age）
*过滤器（“年龄”，年龄）（如果没有运算符，则假定为）
*过滤器（“年龄！=”，年龄）
*过滤器（“年龄范围”，年龄列表）
*筛选（“customers.loyaltyYears in”，yearsList）
如果此查询仅限于类，则可以根据id属性进行筛选。
