Question

请告诉我哪里有问题？我尝试启动我在Spring Boot上开发的第一个应用程序。我已经在SpringMVC上有简单的Web项目，现在我想在BOOT上构建它。这是错误输出：

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'messageSource': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: public lv.intrade.example.dao.TranslationDAO lv.intrade.example.services.Dictionary.translationDAO; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'translationDAOImpl': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private javax.persistence.EntityManagerFactory lv.intrade.example.dao.TranslationDAOImpl.emf; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'entityManagerFactory': Post-processing of FactoryBean's singleton object failed; nested exception is java.lang.IllegalStateException: ApplicationEventMulticaster not initialized - call 'refresh' before multicasting events via the context: org.springframework.boot.context.embedded.AnnotationConfigEmbeddedWebApplicationContext@1a666bf: startup date [Tue Dec 30 23:20:58 EET 2014]; root of context hierarchy

这是我的Application.class

@ComponentScan("lv.intrade.example")
@EnableAutoConfiguration
public class Application {
    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}

我有更多3个类，其中包含@Configuration和@Order注释，其中我已定位@Bean个定义。如果需要更多信息，请问我！我无法找到一些有所需功能的实例。

Answer 1

问题的根源在于DataSourceInitializedPublisher，它在某些bean已注册时发布事件。这个bean由HibernateJpaAutoConfiguration类添加。此类尝试创建LocalContainerEntityManagerFactory但是在您的配置中，您自己创建它。导致早期发射事件。

排除HibernateJpaAutoConfiguration应解决问题，因为禁用了DataSourceInitializedPublisher的注册。

@EnableAutoConfiguration(exclude=org.springframework.boot.autoconfigure.orm.jpa.HibernateJpaAutoConfiguration.class)

关于您的配置，您几乎可以删除所有配置，只需在application.properties文件中添加一些属性即可。

您的WebAppConfig。

@Configuration
public class WebAppConfig  extends WebMvcConfigurerAdapter {

    @Bean(name = "messageSource")
    public MessageSource configureMessageSource() {
        AbstractMessageSource messageSource = new Dictionary();
        return messageSource;
    }

    @Bean
    public LocaleResolver localeResolver() {
        SessionLocaleResolver lr = new SessionLocaleResolver();
        lr.setDefaultLocale(Locale.ENGLISH);
        return lr;
    }

    @Bean
    public LocaleChangeInterceptor localeChangeInterceptor(){
        LocaleChangeInterceptor localeChangeInterceptor=new LocaleChangeInterceptor();
        localeChangeInterceptor.setParamName("lang");
        return localeChangeInterceptor;
    }

    @Override
    public void addInterceptors(InterceptorRegistry registry) {
        registry.addInterceptor(localeChangeInterceptor());
    }

}

并在application.properties添加以下2个属性

spring.view.prefix=/WEB-INF/jsp/
spring.view.suffix=.jsp

现在是您的RootConfig。

@Configuration
public class RootConfig {

    @Bean
    public HibernateJpaSessionFactoryBean sessionFactory(EntityManagerFactory emf) {
        HibernateJpaSessionFactoryBean sessionFactoryBean = new HibernateJpaSessionFactoryBean();
        sessionFactoryBean.setEntityManagerFactory(emf);
        return sessionFactoryBean;
    }
}

并将以下属性添加到application.properties

spring.datasource.url=
spring.datasource.username=
spring.datasource.password=

spring.jpa.database-platform= // Hibernate Dialect
spring.jpa.show-sql=
spring.jpa.hibernate.ddl-auto=
