Question

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() {
            Properties properties = new Properties();
            properties.put("hibernate.hbm2ddl.auto", "update");
            properties.put("hibernate.dialect", "org.hibernate.dialect.PostgreSQLDialect");
            properties.put("hibernate.show_sql", "false");
            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

Answer 1

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() {

Answer 2

Spring无法找到@Configuration类

请参阅以下已解决的问题：

Spring Boot App deployed in Tomcat : Quartz Scheduler bean is not visible from @Service

在tomcat实例中启动Spring Boot War
