Question

我有一个针对mongodb的小示例项目，无法让注释处理器工作。我正在使用以下示例：

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

运行mvn clean install会产生：

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

我到处寻找那个处理器。只是无法找到它。这是pom.xml：

Answer 1

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

Spring Data Mongo提供了一个自定义APT处理器来生成 Metamodels而不是QueryDSL中提供的那个，它会扫描特定于Spring的@Document而不是Morphia特定的注释。

Answer 2

正确的班级名称是com.mysema.query.apt.morphia.MorphiaAnnotationProcessor

尝试使用MongoDB设置Querydsl 3.6.0，但找不到MorphiaAnnotationProcessor
