當我們導入context.xml中兩個不同的罐子

Question

林試圖導入兩個不同的罐中，主要項目的context.xml這樣

<import resource="classpath*:/META-INF/mini-project-1-context.xml" /> 
<import resource="classpath*:/META-INF/mini-project-2-context.xml" /> 

它的失敗，小項目服務，回購協議自動連接自動連接失敗。每個迷你項目都有mysql配置。請找到我的項目結構。

main-project.war 
| 
------- main-project-context.xml 
     |   | 
     |   | 
     |   mini-project-1.jar 
     |      | 
     |      ------- mini-project-1-context.xml 
     |      | 
     |      ------- persistence.xml 
     | 
     mini-project-2.jar 
        | 
        ------- mini-project-2-context.xml 
        | 
        ------- persistence.xml 

find mini-project-1-context.xml。項目名稱只在另一context.xml中

主要項目的context.xml看起來像這樣

<camelContext xmlns="http://camel.apache.org/schema/spring"

即時得到以下錯誤

12:03:33.894 [localhost-startStop-1] DEBUG o.s.b.f.s.DefaultListableBeanFactory - Retrieved dependent beans for bean 'org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter#1e5bc130': [entityManagerFactory]

得到改變

的pom.xml

<dependency> 
    <groupId>com.project</groupId> 
    <artifactId>mini-project-1</artifactId> 
    <version>1.0</version> 
</dependency> 
<dependency> 
    <groupId>com.project</groupId> 
    <artifactId>mini-project-1</artifactId> 
    <version>1.0</version> 
</dependency> 

Answer 1

的問題是由依賴模塊的context.xml中定義transactionManager和annotation-driven（這裏主要項目-context.xml中）得到解決，從罐子項目（小型項目1上下文刪除transactionManager .xml和mini-project-2-context.xml）。

所以從小型項目-1-context.xml中和小型項目-2-context.xml的刪除的transactionManager和annotation-driven。

<bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager"> 
    <property name="entityManagerFactory" ref="entityManagerFactory" /> 
</bean> 
<tx:annotation-driven transaction-manager="transactionManager" /> 

和添加的transactionManager和annotation-driven在主項目的context.xml。

<tx:annotation-driven /> 

<bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager"> 
    <property name="entityManagerFactory" ref="entityManagerFactory" /> 
    <qualifier value="qualifier" /> 
</bean> 

<bean id="transactionManager1" class="org.springframework.orm.jpa.JpaTransactionManager"> 
    <property name="entityManagerFactory" ref="entityManagerFactory1" /> 
    <qualifier value="qualifier1" /> 
</bean>
