【问题描述】：
我正在 Spring Boot Rest api 中使用带有 Web 支持的 Querydsl 实现实体过滤器。我希望能够过滤日期字段，而不是完全匹配，而是按日期或日期。我遇到了这个项目
https://bitbucket.org/gt_tech/spring-data-querydsl-value-operators/src/master/
它似乎有我需要的功能，但是我在生成 Q 类时遇到了问题。目前我正在使用 JPAAnnotationProcessor 作为处理器，但根据该项目文档，我需要使用 QuerydslAnnotationProcessor。如果我用 QuerydslAnnotationProcessor 替换 JPAAnnotationProcessor 并执行 mvn clean install 它不会生成这些类。我还尝试在 Tournament 类上使用 @QueryEntity 注释。
这是我的 pom.xml

我要过滤的实体：
@Entity
public class Tournament {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
private String name;
@JsonFormat(pattern = "yyyy-MM-dd'T'HH:mm:ss")
private Date eventStart;
//getters and setters
}
目前我可以按名称匹配过滤实体，但我需要在 2019-09-01 00:00:01 等之前或之后实施日期过滤。
如何解决 Q 类生成问题，或者有什么更简单的方法可以解决这个问题？
