如何配置弹簧引导

Question

休眠获取下面的错误使用Hibernate配置

Parameter 0 of constructor in org.springframework.boot.autoconfigure.orm.jpa.HibernateJpaAutoConfiguration required a bean of type 'javax.sql.DataSource' that could not be found. 
    - Bean method 'dataSource' not loaded because @ConditionalOnProperty (spring.datasource.jndi-name) did not find property 'jndi-name' 
    - Bean method 'dataSource' not loaded because @ConditionalOnBean (types: org.springframework.boot.jta.XADataSourceWrapper; SearchStrategy: all) did not find any beans 

操作：

考虑重新审视上述条件或定义类型的豆“的javax.sql.DataSource”你组态。

这是我使用

import org.springframework.boot.SpringApplication; 
import org.springframework.boot.autoconfigure.EnableAutoConfiguration; 
import org.springframework.boot.autoconfigure.SpringBootApplication; 
import org.springframework.boot.autoconfigure.data.jpa.JpaRepositoriesAutoConfiguration; 
import org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration; 
import org.springframework.boot.autoconfigure.jdbc.DataSourceTransactionManagerAutoConfiguration; 
@SpringBootApplication 
@EnableAutoConfiguration(exclude={ DataSourceAutoConfiguration.class, 
     DataSourceTransactionManagerAutoConfiguration.class,JpaRepositoriesAutoConfiguration.class}) 
public class Application { 
    public static void main(String[] args) throws Throwable { 

     SpringApplication.run(Application.class, args); 
    } 
} 

属性文件中的Application.java文件 -

spring.jpa.hibernate.ddl-auto=create-drop 
spring.datasource.url=jdbc:oracle:thin:@localhost:1521:ORCL 
spring.datasource.username=system 
spring.datasource.password=**** 
spring.datasource.driver-class-oracle.jdbc.driver.OracleDriver 
spring.datasource.testWhileIdle = true 
spring.datasource.validationQuery = SELECT 1 

spring.jpa.show-sql = true 
spring.jpa.hibernate.ddl-auto = update 
spring.jpa.hibernate.naming-strategy = 
org.hibernate.cfg.ImprovedNamingStrategy 
spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.MySQL5Dialect 

Answer 1

已经排除了DataSourceAutoConfiguration这意味着你必须手动指定@Bean为DataSource。由于排除，application.properties中的数据源配置将不会被加载。
