Maven 在 Hibernate 5.2 中生成的静态元模型无法被 DAO 识别类

Question

我成功生成元模型，所有元模型类都输出到target/annotations目录。 但我的问题是我的其他类例如 DAOImpl 无法识别生成的这些元模型类。有什么帮助吗？

下面是我如何生成元模型使用我的 Maven 项目的 pom.xml 文件:

<plugin>
  <groupId>org.bsc.maven</groupId>
  <artifactId>maven-processor-plugin</artifactId>
  <executions>
    <execution>
      <id>process</id>
      <goals>
        <goal>process</goal>
      </goals>
      <phase>generate-sources</phase>
      <configuration>
        <processors>
          <processor>org.hibernate.jpamodelgen.JPAMetaModelEntityProcessor</processor>
        </processors>
      </configuration>
    </execution>
  </executions>
  <dependencies>
    <dependency>        
      <groupId>org.hibernate</groupId>
      <artifactId>hibernate-jpamodelgen</artifactId>
      <version>4.3.4.Final</version>
    </dependency>
  </dependencies>
</plugin>

检查你是否设置了这个：

 <plugin> <!--Compiler instructions to generate model, add to sources.-->

    <artifactId>maven-compiler-plugin</artifactId>

    <configuration>

        <source>1.6</source>

        <target>1.6</target>

        <compilerArguments>

            <processor>org.hibernate.jpamodelgen.JPAMetaModelEntityProcessor</processor>

        </compilerArguments>

    </configuration>

</plugin>


<plugin><!--path were to generate model, add to -->

    <groupId>org.bsc.maven</groupId>

    <artifactId>maven-processor-plugin</artifactId>

    <executions>

        <execution>

            <id>process</id>

            <goals>

                <goal>process</goal>

            </goals>

            <phase>generate-sources</phase>

            <configuration>

                <!-- source output directory -->

                <outputDirectory>target/metamodel</outputDirectory>

            </configuration>

        </execution>

    </executions>

</plugin>

<plugin>

    <groupId>org.codehaus.mojo</groupId>

    <artifactId>build-helper-maven-plugin</artifactId>

    <version>1.3</version>

    <executions>

        <execution>

            <id>add-source</id>

            <phase>generate-sources</phase>

            <goals>

                <goal>add-source</goal>

            </goals>

            <configuration>

                <sources>

                    <source>target/metamodel</source>

                </sources>

            </configuration>

        </execution>

    </executions>

</plugin>

我认为主要问题是您生成类的文件夹未链接到项目源。你应该告诉你的项目这个目录是源文件夹或者在 src 目录下生成所有内容。
