我有一个功能强大的Spring Boot Web App。
当我从我的Eclipse开始时，一切都很好（参见下面的@SpringBootApplication）
但是当我尝试使用tomcat 7加载生成的WAR时，我在catalina日志文件中收到以下错误
GRAVE: ContainerBase.addChild: start:

似乎webapp启动了一次（在tomcat控制台中看到），然后重新启动并且无法完成启动（???）但是catalina日志中没有第一次启动的痕迹
@SpringBootApplication
public class SchdtoolApplication extends SpringBootServletInitializer {
public static void main(String[] args) {
SpringApplication.run(SchdtoolApplication.class, args);
}
}
@Configuration
@EnableWebMvc
@EnableTransactionManagement
@ComponentScan("fr.myapp")
public class WebAppConfig extends WebMvcConfigurerAdapter {
@Bean
public DataSource dataSource() {
SimpleDriverDataSource d = new SimpleDriverDataSource();
d.setConnectionProperties(dProperties());
d.setDriverClass(Driver.class);
d.setUrl("jdbc:postgresql://localhost:5432/mydb");
d.setUsername("BNF0016779");
d.setPassword("");
return d;
}
@Bean
public LocalContainerEntityManagerFactoryBean entityManagerFactory() {
LocalContainerEntityManagerFactoryBean entityManagerFactoryBean = new LocalContainerEntityManagerFactoryBean();
entityManagerFactoryBean.setDataSource(dataSource());
entityManagerFactoryBean.setPersistenceProviderClass(HibernatePersistenceProvider.class);
entityManagerFactoryBean.setPackagesToScan("fr.myapp");
entityManagerFactoryBean.setJpaProperties(hibProperties());
return entityManagerFactoryBean;
}
private Properties hibProperties() {

return properties;
}
private Properties dProperties() {
Properties properties = new Properties();
properties.put("spring.jpa.database", "POSTGRESQL");
return properties;
}
@Autowired
private ApplicationContext applicationContext;
@Bean
public SchedulerFactoryBean configureScheduler() {
SchedulerFactoryBean f = new SchedulerFactoryBean();
f.setDataSource(dataSource());
f.setJobFactory(new SpringBeanJobFactory());
f.setAutoStartup(false);
Properties properties = new Properties();
properties.setProperty("org.quartz.threadPool.threadCount", "3");
properties.setProperty("org.quartz.jobStore.useProperties", "false");
properties.setProperty("org.quartz.jobStore.driverDelegateClass", "org.quartz.impl.jdbcjobstore.PostgreSQLDelegate");
f.setQuartzProperties(properties);
f.setApplicationContext(applicationContext);
f.setApplicationContextSchedulerContextKey("applicationContext");
return f;
}
}
我也会收到这个错误吗？
tomcat-embed-el-8.0.28.jar) - jar not loaded. See Servlet Spec 3.0, section 10.7.2. Offending class: javax/el/Expression.class
答案 0 :(得分：0)
好的，所以你的问题是
Caused by: org.springframework.beans.factory.NoUniqueBeanDefinitionException: No qualifying bean of type [javax.persistence.EntityManager] is defined: expected single matching bean but found 3: org.springframework.orm.jpa.SharedEntityManagerCreator#0,org.springframework.orm.jpa.SharedEntityManagerCreator#1,org.springframework.orm.jpa.SharedEntityManagerCreator#2
当您有多个entitymanager时会出现此问题。
@Bean(name = "your-entity-manager-factory")
@Primary
public LocalContainerEntityManagerFactoryBean entityManagerFactory() {
答案 1 :(得分：0)
Spring无法找到@Configuration类
请参阅以下已解决的问题：
