BeanCurrentlyInCreationException Spring Boot

Question

我該如何解決這個異常？

沒有Spring Boot一切正常。

所以問題出現在「應用」部分，對嗎？

捕捉到異常

BeanCurrentlyInCreationException: Error creating bean with name 'pooledConnectionFactory': 
Requested bean is currently in creation: Is there an unresolvable circular reference? 

應用

@ComponentScan 
@EnableAutoConfiguration 
@ImportResource("classpath:contexts/bean-locations.xml") 
public class MyApp{ 
public static void main(String[] args) throws Exception { 
    new SpringApplication(MyApp.class).run(args); 
} 
} 

通過導入

豆使用進口

<import resource="classpath*:contexts/database/datasource/base-data-source.xml"/> 
<import resource="classpath*:contexts/database/datasource/pooled-data-source.xml"/> 

第一個文件：

<beans xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xmlns="http://www.springframework.org/schema/beans" 
    xsi:schemaLocation="http://www.springframework.org/schema/beans 
     http://www.springframework.org/schema/beans/spring-beans-4.2.xsd"> 
<bean id="baseDataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource"> 
    <property name="driverClassName" value="${connection.driverClassName}"/> 
    <property name="username" value="${connection.userName}"/> 
    <property name="password" value="${connection.password}"/>

春季啓動具有Database initialization功能，與你的DataSource配置衝突。見DataSourceInitializer課。它試圖在創建之前獲取數據源。

爲了可以

1. 禁用初始化使用屬性

   spring.datasource.initialize=false 
   

2. 排除數據源自動配置，你有你自己的配置

   @EnableAutoConfiguration(exclude={DataSourceAutoConfiguration.class})
