Question

这是我第一次使用Spring-Data-jpa和Querydsl。

我正在尝试配置DataModel的自动生成。

我执行了以下步骤：

我在pom.xml

添加了以下依赖项

    <dependency>
        <groupId>com.mysema.querydsl</groupId>
        <artifactId>querydsl-apt</artifactId>
        <version>3.2.1</version>
    </dependency>
    <dependency>
        <groupId>com.mysema.querydsl</groupId>
        <artifactId>querydsl-jpa</artifactId>
        <version>3.2.1</version>
    </dependency>
    <dependency>
        <groupId>com.mysema.querydsl</groupId>
        <artifactId>querydsl-core</artifactId>
        <version>3.2.1</version>
    </dependency>

然后我添加了以下插件

      <plugin>
            <groupId>com.mysema.maven</groupId>
            <artifactId>maven-apt-plugin</artifactId>
            <version>1.0.2</version>
            <executions>
                <execution>
                    <goals>
                        <goal>process</goal>
                    </goals>
                    <phase>generate-sources</phase>
                    <configuration>
                        <outputDirectory>target/generated-sources/java</outputDirectory>
                        <processor>com.mysema.query.apt.jpa.JPAAnnotationProcessor</processor>
                    </configuration>
                </execution>
            </executions>
        </plugin>

但是我在pom.xml中总是遇到同样的错误：

生命周期配置未涵盖的插件执行：com.mysema.maven：maven-apt-plugin：1.0.2：process（执行：默认，阶段：生成源）

并且未生成并填充文件夹target / generated-sources / java。我在哪里？

Answer 1

使用此插件，它的版本为1.1.1

<plugin>
                <groupId>com.mysema.maven</groupId>
                <artifactId>apt-maven-plugin</artifactId>
                <version>1.1.1</version>
                <executions>
                    <execution>
                        <phase>generate-sources</phase>
                        <goals>
                            <goal>process</goal>
                        </goals>
                        <configuration>
                            <!-- Specifies the directory in which the query types are generated -->
                            <outputDirectory>target/generated-sources</outputDirectory>
                            <!-- States that the APT code generator should look for JPA annotations -->
                                <processor>com.mysema.query.apt.jpa.JPAAnnotationProcessor</processor>
                        </configuration>
                    </execution>
                </executions>
            </plugin>

依赖关系：

<!-- Query DSL -->
        <dependency>
            <groupId>com.mysema.querydsl</groupId>
            <artifactId>querydsl-core</artifactId>
            <version>3.4.3</version>
        </dependency>

        <dependency>
            <groupId>com.mysema.querydsl</groupId>
            <artifactId>querydsl-apt</artifactId>
            <version>3.4.3</version>
        </dependency>

        <dependency>
            <groupId>com.mysema.querydsl</groupId>
            <artifactId>querydsl-jpa</artifactId>
            <version>3.4.3</version>
        </dependency>
        <dependency>
            <groupId>org.slf4j</groupId>
            <artifactId>slf4j-log4j12</artifactId>
        </dependency>

构建插件：

<plugin>
                        <groupId>com.mysema.maven</groupId>
                        <artifactId>apt-maven-plugin</artifactId>
                        <version>1.1.3</version>
                        <executions>
                            <execution>
                                <goals>
                                    <goal>process</goal>
                                </goals>
                                <configuration>
                                    <outputDirectory>target/generated-sources/java</outputDirectory>
                                    <processor>com.mysema.query.apt.jpa.JPAAnnotationProcessor</processor>
                                </configuration>
                            </execution>
                        </executions>
                    </plugin>

如果您使用m2e

，请使用以下内容

<plugin>
    <groupId>com.mysema.maven</groupId>
    <artifactId>apt-maven-plugin</artifactId>
    <version>1.1.1</version>
    <executions>
        <execution>
            <goals>
                <goal>process</goal>
            </goals>
            <configuration>
                <outputDirectory>target/generated-sources/java</outputDirectory>
                <processor>com.mysema.query.apt.jpa.JPAAnnotationProcessor</processor>
            </configuration>
        </execution>
        </executions>
        <dependencies>
            <dependency>
                <groupId>com.mysema.querydsl</groupId>
                <artifactId>querydsl-apt</artifactId>
                <version>3.6.7</version>

            <dependency>
                <groupId>com.mysema.querydsl</groupId>
                <artifactId>querydsl-jpa</artifactId>
                <classifier>apt</classifier>
                <version>3.6.7</version>
            </dependency>
        </dependencies>
    </plugin>

更改已安装的JRE：jre - ＆gt; jdk解决了这个问题

Maven querydsl配置不起作用
