大佬教程收集整理的这篇文章主要介绍了Java SE + Spring Data + Hibernate，大佬教程大佬觉得挺不错的，现在分享给大家，也给大家做个参考。
你看到的异常不是由无效的Spring配置引起的，而是由你的类路径设置引起的。感觉就像关于ASM库和Java 8的版本不兼容。已知Spring 3.2依赖的ASM版本与Java 8不兼容。
因此，如果要使用Java 8运行代码，则需要使用最新的Spring 4.0版本。
我正在尝试使用Spring Data + Hibernate启动Java SE应用程序，并且到目前为止已经完成了以下工作：
配置文件
@Configuration
@Propertysource("classpath:hibernate.properties")
@EnableJpaRepositories
@EnabletransactionManagement
public class JpaConfiguration {
private static final String PROPERTY_NAME_DATABASE_DRIVER = "db.driver";
private static final String PROPERTY_NAME_DATABASE_password = "db.password";
private static final String PROPERTY_NAME_DATABASE_URL = "db.url";
private static final String PROPERTY_NAME_DATABASE_USERNAME = "dB.USERNAME";
private static final String PROPERTY_NAME_HIBERNATE_DIALECT = "hibernate.dialect";
private static final String PROPERTY_NAME_HIBERNATE_SHOW_SQL = "hibernate.show_sql";
private static final String PROPERTY_NAME_ENTITymANAGER_PACKAGES_TO_SCAN =
"entitymanager.packages.to.scan";
@resource
private Environment env;
@Bean
public Datasource datasource() {
DriveRMANagerDatasource datasource = new DriveRMANagerDatasource();
datasource.setDriverClassName(
env.getrequiredProperty(PROPERTY_NAME_DATABASE_DRIVER));
datasource.setUrl(env.getrequiredProperty(PROPERTY_NAME_DATABASE_URL));
datasource.setUsername(env.getrequiredProperty(PROPERTY_NAME_DATABASE_USERName));
datasource.setpassword(env.getrequiredProperty(PROPERTY_NAME_DATABASE_password));
return datasource;
}
@Bean
public LocalContainerEntitymanagerFactoryBean entitymanagerFactory() {
LocalContainerEntitymanagerFactoryBean entitymanagerFactoryBean = new
LocalContainerEntitymanagerFactoryBean();
entitymanagerFactoryBean.setDatasource(datasource());
entitymanagerFactoryBean.setPersistenceProviderClass(org.hibernate
.jpa.HibernatePersistenceProvider.class);
entitymanagerFactoryBean.setPackagesToScan(env.
getrequiredProperty(PROPERTY_NAME_ENTITymANAGER_PACKAGES_TO_SCAN));
entitymanagerFactoryBean.setJpaProperties(hibProperties());
return entitymanagerFactoryBean;
}
private Properties hibProperties() {
Properties properties = new Properties();
properties.put(PROPERTY_NAME_HIBERNATE_DIALECT,env.getrequiredProperty(PROPERTY_NAME_HIBERNATE_DIALECT));
properties.put(PROPERTY_NAME_HIBERNATE_SHOW_SQL,env.getrequiredProperty(PROPERTY_NAME_HIBERNATE_SHOW_SQL));
return properties;
}
@Bean
public JpatransactionManager transactionManager() {
JpatransactionManager transactionManager = new JpatransactionManager();
transactionManager.setEntitymanagerFactory(entitymanagerFactory().getObject());
return transactionManager;
}
@Bean
public MainBean mainBean() {
return new MainBean();
}
}
Start class
public class Start {
private static final String CONFIG_PACKAGE = "org.app.config";
public static void main(String[] args) {
try (AnnotationConfigApplicationContext ctx = new
AnnotationConfigApplicationContext()) {
ctx.scan(CONFIG_PACKAGE);
ctx.refresh();
MainBean bean = ctx.getBean(MainBean.class);
bean.start();
}
}
}
public class MainBean {
public void start() {
System.out.println("Application Started. . .");
}
}
但是我收到以下异常
Exception in thread "main" org.springframework.beans.factory.beanDefinitionStoreException: Failed to read candidate component class: file [C:\MyPath\target\classes\org\app\config\JpaConfiguration.class]; nested exception is java.lang.IllegalArgumentexception

有人知道我在做什么错吗？
