从包生成QueryDsl Q类

Question

如何仅通过指定包名称来生成QueryDsl Q-Class？鉴于源类位于我的target/generated-sources文件夹中,因为它们是其他构建插件(WSDL,XSD等)的产品.

我尝试使用以下插件,但找不到正确的配置:

<groupId>com.mysema.querydsl</groupId>
<artifactId>querydsl-maven-plugin</artifactId>
<version>2.9.0</version>
<executions>
    <phase>generate-sources</phase>
    <goals>
        <goal>process</goal>
    </goals>
    <configuration>
        <outputDirectory>target/generated-sources</outputDirectory>
        <processor>${com.mysema.query.apt.ProcessorClass}</processor>
    </configuration>
</executions>

和:

<groupId>com.mysema.maven</groupId> 
<artifactId>maven-apt-plugin</artifactId> 
<version>1.0.4</version> 

我想做的是这样的事情:

<configuration>
    <packageName>com.my.package</packageName>
    <sourceFolder>target/generated-sources</sourceFolder>
    <targetFolder>target/generated-sources/querydsl</targetFolder>
</configuration>

...会生成类:

• com.my.package.QFoo.java
• com.my.package.QBar.java

由于没有常见的JPA或JDO注释,并且我无法访问源文件,因此我无法将任何com.mysema.query.apt.*Processors用于maven-apt-plugin <processor>.

编辑1:添加了完整的maven-apt-plugin配置.

编辑2: - 我能够通过maven命令行偶尔使用maven-apt-plugin工作,但不是通过扩展AbstractQuerydslProcessor来查找@XmlType注释类而不是Eclipse/STS.双代码生成无疑是不理想的解决方案.

答案是使用Timo在此概述的策略生成Q-class:https://github.com/mysema/querydsl/issues/196

在我的模块中package-info.java:

@QueryEntities({ com.remote.module.Foo.class,
    com.remote.module.Bar.class })
package com.my.local.module.querydsl;

import com.mysema.query.annotations.QueryEntities;

Maven POM中的插件执行:

<plugin>
    <groupId>com.mysema.maven</groupId>
    <artifactId>apt-maven-plugin</artifactId>
    <executions>
        <execution>
            <id>apt-maven-plugin-remote-module-QuerydslAnnotationProcessor</id>
            <goals>
                <goal>process</goal>
            </goals>
            <configuration>
                <outputDirectory>target/generated-sources</outputDirectory>
                <showWarnings>true</showWarnings>
                <!-- genereate Q-classes specified in package-info.java -->
                <processor>com.mysema.query.apt.QuerydslAnnotationProcessor</processor>
            </configuration>
        </execution>
    </executions>
    <dependencies>
        <dependency>
            <groupId>com.mysema.querydsl</groupId>
            <artifactId>querydsl-apt</artifactId>
        </dependency>
    </dependencies>
</plugin>
