QueryDsl生成的类抛出未定义的构造方法

问题描述

我在Spring Boot项目中添加了Query DSL。并且，通过“ mvn compile”生成了QType类。一些生成的类具有如下编译错误： The constructor QAddress(Class<Address>,PathMetadata,PathInits) is undefined用于以下构造函数，

public QAddress(String variable) {
    this(Address.class,forVariable(variable),INITS);
}

public QAddress(Path<? extends Address> path) {
    this(path.getType(),path.getMetadata(),PathInits.getFor(path.getMetadata(),INITS));
}

您能否让我知道我在这方面缺少什么？

pom.xml

<dependency> 
        <groupId>com.querydsl</groupId> 
        <artifactId>querydsl-apt</artifactId> 
        <version>4.4.0</version>
        </dependency>
    <dependency>

                    </goals>
                    <configuration>
                        <outputDirectory>target/generated-sources/java</outputDirectory>
                        <processor>com.querydsl.apt.jpa.JPAAnnotationProcessor</processor>
                    </configuration>
                </execution>
            </executions>
        </plugin>

解决方法

尝试包括querydsl-core依赖项：

<!-- https://mvnrepository.com/artifact/com.querydsl/querydsl-core -->
    <dependency>
        <groupId>com.querydsl</groupId>
        <artifactId>querydsl-core</artifactId>
        <version>4.4.0</version>
    </dependency>

将其包含在pom.xml中后进行编译。
