org.hibernate.hql.internal.ast.querysyntaxception:实体未映射

spring-boot maven hibernate spring java

Marc · 技术社区 · 6 年前

当我试图运行一个打包成胖jar的spring启动应用程序时,我面临着一些奇怪的问题。

mvn spring-boot:run 但是当我使用 java -jar myjar 没有映射hibernate实体。

Caused by: org.hibernate.hql.internal.ast.QuerySyntaxException: Entity is not mapped
        at org.hibernate.hql.internal.ast.util.SessionFactoryHelper.requireClassPersister(SessionFactoryHelper.java:169) ~[hibernate-core-5.2.17.Final.jar!/:5.2.17.Final]

我知道是不同的,因为它改变了类路径,但是有没有一种方法可以用verbose运行它,这样我就可以看到类路径是什么,这样我就可以使用 java -jar 有类似的东西吗?

System.getProperty("java.class.path");

我明白了

 Classpath:/usr/local/apache-maven/boot/plexus-classworlds-2.5.2.jar

当我从 java -jar myJar.jar ,我明白了 myJar.jar 所以这可能就是它不起作用的原因。

这是主课

@SpringBootApplication
@ComponentScan("com.foo")
public class Application  extends SpringBootServletInitializer {
    private static final Logger LOG = LoggerFactory.getLogger(Application.class);

    public static void main(String[] args) {
        if (!argurmentsValid(args)) {
            return;
        }

        final SpringApplication app = new SpringApplication(Application.class);
        app.setBannerMode(Banner.Mode.OFF);
        app.run(args);
    }
}

下面是api内部的配置

@Configuration
@ApplicationPath("/api")
public class ApiConfiguration extends ResourceConfig {
    public static final String CONFIG_FILE_NAME = "api.properties";

    public ApiConfiguration() {
        register(com.foo.api.v1.controllers.aController.class);
    }
}

@Configuration
@ComponentScan("com.foo.service")
@EnableTransactionManagement
public class ServiceConfiguration {

    @Bean
    public PersistenceAnnotationBeanPostProcessor persistenceAnnotationBeanPostProcessor() {
        return new PersistenceAnnotationBeanPostProcessor();
    }

    @Bean
    public LocalContainerEntityManagerFactoryBean localContainerEntityManagerFactoryBean () {
        return new LocalContainerEntityManagerFactoryBean();
    }

    @Bean
    public JpaTransactionManager jpaTransactionManager() {
        return new JpaTransactionManager();
    }
}

我在com.foo.service中有常规的hibernate实体。

我用 mvn clean install 然后我用 java -jar jar-with-all-dependencies.jar

我需要知道一些细节才能帮助你:

1-你是怎么包装成胖罐子的? 2-你是怎么操作的?

我最近为springboot应用程序创建了一个fatjar,它运行得很好,但是我不得不使用重新打包的gradle插件来正确地重新组装jar。这个插件是spring做的,你可能和maven有相同的地方。

你看过这里吗?: https://docs.spring.io/spring-boot/docs/current/reference/html/build-tool-plugins-maven-plugin.html

产科加强生命支持

您在哪里指定了EntityScan路径?问题可能是弹簧,不要扫描包裹
你忘了给java-jar传递参数了吗,比如spring.profiles.active?

对于fatJar,您需要:

特殊的springboot包装(使用插件)
指定主类(您已经完成了)
通过所需的系统参数(配置文件等)

关于最后一点,我注意到springboot打包在使用java-jar运行时没有考虑我的-D参数,我不得不使用JavaExec gradle插件。
