querydsl-jpa与spring-data-jpa 1.10.0一起使用时出现3.7.3错误

Question

我正在使用

<groupId>com.mysema.querydsl</groupId>
<artifactId>querydsl-jpa</artifactId>
<version>3.7.3</version>

没问题

<groupId>org.springframework.data</groupId>
<artifactId>spring-data-jpa</artifactId>
<version>1.9.4.RELEASE</version>

而是使用

<groupId>org.springframework.data</groupId>
<artifactId>spring-data-jpa</artifactId>
<version>1.10.1.RELEASE</version>

在相同的代码我有以下错误:

[ERROR] /C:/Prj/Java/Eclipse/Elfolab/src/main/java/com/interlabsrl/elfolab/persistence/multiple/repository/elettroforesi/springdatajpa/LinguaRepository.java:[13,8] cannot access com.querydsl.core.types.OrderSpecifier

有关这些版本之间有什么问题的想法吗？

编辑:

运用

    <dependency>
        <groupId>com.querydsl</groupId>
        <artifactId>querydsl-jpa</artifactId>
        <version>4.1.0</version>
    </dependency>   

我仍然有这些错误:

C:\Prj\Java\Eclipse\Elfolab\src\main\java\com\interlabsrl\elfolab\persistence\multiple\repository\elettroforesi\table\custom\impl\MetodicaRepositoryImpl.java:11: error: package com.mysema.query.jpa.impl does not exist
import com.mysema.query.jpa.impl.JPAQuery;

Answer 1

代替

<dependency>
    <groupId>com.mysema.querydsl</groupId>
    <artifactId>querydsl-*</artifactId>
    <version>3.7.3</version>
</dependency>

你现在应该使用

<dependency>
    <groupId>com.querydsl</groupId>
    <artifactId>querydsl-*</artifactId>
    <version>4.1.3</version>
</dependency>

jar文件中的包也已更改,因此您必须在源代码中更改导入的querydsl类.

Answer 2

您应该将 querydsl 的版本更新到 4.1。请注意，groupId 也已更改。

在这里您可以看到 1.10.1.RELEASE 使用 querydsl 的 4.1，这可能会干扰您使用旧版本。
