Question

我正在尝试使用此处描述的替代方法从groovy实体生成querydsl类http://www.querydsl.com/static/querydsl/2.7.3/reference/html/ch03s02.html

我遇到的问题是这些类只在我执行mvn编译/包两次

时生成

即。有关顺序的东西，应该在编译groovy类之前生成类

否则我收到编译错误

Groovy:unable to resolve class com.application.domain.QUser

我的pom.xml

我缺少什么？

你需要：

编译源Groovy代码
生成QClasses的后处理类

再次编译生成的QClass。

    <plugin>
        <groupId>com.mysema.querydsl</groupId>
        <artifactId>querydsl-maven-plugin</artifactId>
        <version>${querydsl.version}</version>
        <executions>
            <execution>
                <id>generate-query-dsl-classes</id>
                <phase>process-classes</phase>
                <goals>
                    <goal>jpa-export</goal>
                </goals>
                <configuration>
                    <targetFolder>target/generated-sources/java</targetFolder>
                    <packages>
                        <package>com.my.package</package>
                    </packages>
                </configuration>
            </execution>
            <execution>
                <id>compile-query-dsl-classes</id>
                <phase>process-classes</phase>
                <goals>
                    <goal>compile</goal>
                </goals>
                <configuration>
                    <sourceFolder>target/generated-sources/java</sourceFolder>
                </configuration>
            </execution>
        </executions>
    </plugin>

使用带有groovy-eclipse-compiler的querydsl-maven-plugin生成QueryDsl类
