Spring Boot with Hibernate应用程序启动失败

Question

当我启动我的Spring Boot应用程序时，我得到了：

2020-11-11 03:02:24.333 WARN 20648 - main bean :上下文初始化过程中遇到异常-取消刷新尝试: org.springframework.beans.factory.UnsatisfiedDependencyException:创建名为'org.springframework.boot.autoconfigure.orm.jpa.HibernateJpaConfiguration'：的bean时出错，通过构造函数参数0表示的依赖项不满足；嵌套异常是org.springframework.beans.factory.BeanCreationException:在通过工厂方法实例化类路径资源org/springframework/boot/autoconfigure/jdbc/DataSourceConfiguration$Hikari.class: ConfigServletWebServerApplicationContext中定义的名为'dataSource‘的Bean时出错；嵌套异常是org.springframework.beans.BeanInstantiationException:无法实例化Tomcat2020-11-11 03:02:24.335信息20648 - main o.apache.catalina.core.StandardService :停止服务Tomcat2020-11-11 03:02:02:24.486信息20648 - main ConditionEvaluationReportLoggingListener :停止服务Tomcat 2020-11-11 03:02:02:24.486信息2020-11-11 03:02:24.486信息2020-11-11 03:02:02:24.486信息2020-11-11 03:02:24.486信息2020-11-11 03:02:02:24.486信息2020-11-11 03:02:24.486信息2020-11-11 03:02:02:24.486信息2020-11-11 03:02:02:24.486信息2020-11-11 03:02:02:24.486信息2020-11-11 03:02:02:24.486信息2020-main ConditionEvaluationReportLoggingListener：

启动ApplicationContext时出错。要显示条件报告，请在启用“debug”的情况下重新运行应用程序。20648 -11-11 03:02:24.489错误2020- main o.s.b.d.LoggingFailureAnalysisReporter：

应用程序启动失败

描述：

无法配置url:未指定“”datasource“”属性，并且无法配置嵌入的数据源。“”

原因:无法确定合适的驱动程序类

操作：

考虑以下几点:如果您需要一个嵌入式数据库(H2、HSQL或Derby)，请将其放在类路径中。如果您有要从特定配置文件加载的数据库设置，则可能需要激活它(当前没有活动的配置文件)。

你能告诉我该怎么做才能解决这个问题吗？

Answer 1

只需使用application.properties文件即可设置数据源url

spring:
    datasource:
        url: 'jdbc:mssql://localhost:5432/dbname'
        username: username
        password: password 

Answer 2

我最终解决了这个问题，只需添加

spring.autoconfigure.exclude=org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration

到Spring Boot application.properties

Answer 3

我的配置文件：

package com.projectparty.config;

import org.springframework.boot.jdbc.DataSourceBuilder;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.orm.hibernate5.HibernateTransactionManager;
import org.springframework.orm.hibernate5.LocalSessionFactoryBean;
import org.springframework.transaction.PlatformTransactionManager;
import org.springframework.transaction.annotation.EnableTransactionManagement;

import javax.sql.DataSource;
import java.util.Properties;

@Configuration
@EnableTransactionManagement
public class HibernateConfig {

    @Bean
    public DataSource dataSource() {
        return DataSourceBuilder.create()
                .driverClassName("com.microsoft.sqlserver.jdbc.SQLServerDriver")
                .url("jdbc:sqlserver://127.0.0.1:51264")
                .username("admin")
                .password("admin")
                .build();
    }


    @Bean
    public LocalSessionFactoryBean sessionFactory() {
        LocalSessionFactoryBean sessionFactory = new LocalSessionFactoryBean();
        sessionFactory.setDataSource(dataSource());
        sessionFactory.setHibernateProperties(hibernateProperties());

        return sessionFactory;
    }

    @Bean
    public PlatformTransactionManager hibernateTransactionManager() {
        HibernateTransactionManager transactionManager
                = new HibernateTransactionManager();
        transactionManager.setSessionFactory(sessionFactory().getObject());

        return transactionManager;
    }

    private Properties hibernateProperties() {
        Properties hibernateProperties = new Properties();
        hibernateProperties.setProperty(
                "hibernate.hbm2ddl.auto", "update");
        hibernateProperties.setProperty(
                "hibernate.dialect", "org.hibernate.SQLServerDialect");

        return hibernateProperties;
    }
}
