SpringBoot应用程序崩溃 [英] SpringBoot application crash
本文介绍了SpringBoot应用程序崩溃的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
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：
Tell me please where I have problem? I try to start my first application developed on Spring Boot. I already have simple web project on SpringMVC and now I like to build it on BOOT. Here is error output:

这是我的Application.class
And here is my Application.class
@ComponentScan("lv.intrade.example")
@EnableAutoConfiguration
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}
我还有3个课程 @Configuration 和 @Order 注释我放置了 @Bean 定义。
如果需要更多信息，请问我！
我找不到一些带有所需功能的实例。
And I have more 3 classes with @Configuration and @Order annotations where I've placed @Bean definitions.
If need more information, ask me!
I can't find some worked example with needed features.
推荐答案
问题的根源在于< a href =https://github.com/spring-projects/spring-boot/blob/master/spring-boot-autoconfigure/src/main/java/org/springframework/boot/autoconfigure/orm/jpa/DataSourceInitializedPublisher。 javarel =nofollow> DataSourceInitializedPublisher ，它在已注册某些bean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。
The root of the problem lies in the DataSourceInitializedPublisher which publishes an event when certain beans have been registered. This bean is added by the HibernateJpaAutoConfiguration class. This class tries to create a LocalContainerEntityManagerFactory however in your configuration you are creating it yourself. Leading to early firing of events.
排除 HibernateJpaAutoConfiguration 应解决问题，因为禁用 DataSourceInitializedPublisher <的注册/ code>。
Excluding the HibernateJpaAutoConfiguration should fix the problem as that disable the registration of the DataSourceInitializedPublisher.
@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中添加一些属性文件。
Regarding your configuration you can almost remove all of it and simply put some properties in the application.properties files.
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());
}
}
并且在 application.properties 添加以下2个属性
And in the application.properties add the following 2 properties
spring.view.prefix=/WEB-INF/jsp/
spring.view.suffix=.jsp
现在你的 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=
spring.jpa.properties.hibernate.format_sql=true
有关更多属性，请参阅参考guide.
For more properties see the reference guide.
Your Initializer can be removed as that doesn't do anything in a Spring Boot application. I might have missed a couple of properties but this should give you a start and feel for what Spring Boot can do for you.

Note: I’m not sure why you need both JPA and plain hibernate if you can do it with JPA only you can simply remove your RootConfig completely.
