java - 尝试使用 MongoDB 设置 Querydsl 3.6.0，但未找到 MorphiaAnnotationProcessor

Question

我有一个用于 mongodb 的小示例项目，但无法让注释处理器工作。我使用的示例来自:

http://www.querydsl.com/static/querydsl/latest/reference/html/ch02s07.html

运行 mvn clean install 产生:

Annotation processor 'com.querydsl.mongodb.morphia.MorphiaAnnotationProcessor' not found

我到处寻找那个处理器。就是找不到。这是 pom.xml:

Answer 1

使用 Spring Data，你应该使用 org.springframework.data.mongodb.repository.support.MongoAnnotationProcessor

Spring Data Mongo provides a custom APT processor to generate the Metamodels instead of the one provided in QueryDSL, it will scan the Spring specific @Document instead of the Morphia specific annotations.
