Question

В настоящее время работает над проектом Spring MVC.Он использует Apache Tomcat для получения данных из моей базы данных SQL.

В настоящее время я могу получать данные из одного источника данных, но моя следующая цель - получить информацию из двух источников данных.,

Вот изображение структуры файла

Файл context.xml с информацией об источнике данных

<Context useHttpOnly="true">

<Realm
className="com.sentry.tomcat.realm.AuthenticationServiceRealm"
applicationName="CLUB"
environmentName="Dev"
logicalDomainNames="Intranet,ServiceAccounts"
authenticationProfileName="SentryLogin" 
/>

<Valve
className="org.apache.catalina.valves.AccessLogValve"
directory="${server.log.base}"
fileDateFormat="yyyy-MM-dd"
pattern="%t ${server.hostName}  ${server.domainName}    ${tomcat.instancename}  Dev %a  %{X-Forwarded-For}i %m  %U  %q  %p  %u  %v  %A  %H  %{User-Agent}i  %S  %I  %{Referer}i %s  %b  %D  tomcat_v2"
prefix="SEL_access_log_tomcat_v2."
suffix=".log"
/>

<Resource
logAbandoned="true" 
removeAbandonedOnBorrow="true" 
removeAbandonedTimeout="60000"
testOnBorrow="true"
validationQuery="SELECT 1"
maxWaitMillis="10000"
maxIdle="100"
maxTotal="100"
url="jdbc:sqlserver://*server name*;databaseName=*db name*;integratedSecurity=true;sendStringParametersAsUnicode=false"
driverClassName="com.microsoft.sqlserver.jdbc.SQLServerDriver"
type="javax.sql.DataSource"
auth="Container"
name="jdbc/CLUB"
/>

 <Resource
logAbandoned="true" 
removeAbandonedOnBorrow="true" 
removeAbandonedTimeout="60000"
testOnBorrow="true"
validationQuery="SELECT 1"
maxWaitMillis="10000"
maxIdle="100"
maxTotal="100"
url="jdbc:sqlserver://*server name*;databaseName=*db name*;integratedSecurity=true;sendStringParametersAsUnicode=false"
driverClassName="com.microsoft.sqlserver.jdbc.SQLServerDriver"
type="javax.sql.DataSource"
auth="Container"
name="jdbc/PC"
/>

Файл application-context.xml, который импортирует два разных ресурса.

<?xml version="1.0" encoding="UTF-8"?>
<import resource="CLUB-datasource-context.xml"/> 
<import resource="PC-datasource-context.xml"/> 

<context:component-scan base-package="com.sentry.club.service" />

Мне удалось решить проблему. В каждом из файлов datasource-context.xml необходимо однозначно назвать компоненты (включая entityManager, TransactionsManager и т. Д.). Кроме того, вам нужно сослаться на менеджер сущностей в элементе jpa: repositories с атрибутом entity-manager-factory-ref = =.
