Hibernate 如何生成 JPA 的 Metamodel
要在 Hibernate 中生成 JPA 的 Metamodel。
你只需要在 pom.xml 进行下面的 2 个操作就可以了。
添加依赖
在 POM 中添加下面的依赖。
编译插件
在编译插件中,添加编译参数
完整的编译参数如下图
注意上图中的插件配置。
进行编译
运行命令:mvn compile
输出如下:
PS C:\WorkDir\USRealEstate\Source-Code\mls-common> mvn compile[INFO] Scanning for projects...[INFO][INFO] --------------------< com.ossez.usreio:mls-common >---------------------[INFO] Building Mls-Common 0.0.1-SNAPSHOT[INFO] --------------------------------[ jar ]---------------------------------[INFO][INFO] --- maven-resources-plugin:2.6:resources (default-resources) @ mls-common ---[INFO] Using 'UTF-8' encoding to copy filtered resources.[INFO] Copying 5 resources[INFO][INFO] --- maven-compiler-plugin:3.8.1:compile (default-compile) @ mls-common ---[INFO] Changes detected - recompiling the module![INFO] Compiling 35 source files to C:\WorkDir\USRealEstate\Source-Code\mls-common\target\classes[INFO] /C:/WorkDir/USRealEstate/Source-Code/mls-common/src/main/java/com/ossez/usreio/mls/common/dao/factories/ListingMlsPhotoFactory.java: Some input files use or override a deprecated API.[INFO] /C:/WorkDir/USRealEstate/Source-Code/mls-common/src/main/java/com/ossez/usreio/mls/common/dao/factories/ListingMlsPhotoFactory.java: Recompile with -Xlint:deprecation for details.[INFO] /C:/WorkDir/USRealEstate/Source-Code/mls-common/src/main/java/com/ossez/usreio/mls/common/dao/factories/ListingMlsPhotoFactory.java: Some input files use unchecked or unsafe operations.[INFO] /C:/WorkDir/USRealEstate/Source-Code/mls-common/src/main/java/com/ossez/usreio/mls/common/dao/factories/ListingMlsPhotoFactory.java: Recompile with -Xlint:unchecked for details.[INFO] ------------------------------------------------------------------------[INFO] BUILD SUCCESS[INFO] ------------------------------------------------------------------------[INFO] Total time: 2.738 s[INFO] Finished at: 2022-01-12T16:52:51-05:00[INFO] ------------------------------------------------------------------------PS C:\WorkDir\USRealEstate\Source-Code\mls-common>
然后 Maven 将会在 target 文件夹中生成 Metamodel 的源代码。
生成的源代码如上图。
