使用JNDI Connection進行Grails 3.1.1部署

[英]Grails 3.1.1 deployment with JNDI Connection

 原文  2016-10-25 04:44:35  7   1    tomcat/ grails/ jndi

問題描述

我正在使用grails 3.1.1，我試圖用jndi連接來配置我的應用程序，例如..

25-Oct-2016 11:41:03.764 INFO [main] org.apache.coyote.AbstractProtocol.start Starting ProtocolHandler [http-nio-8090] 25-Oct-2016 11:41:03.770 INFO [main] org.apache.coyote.AbstractProtocol.start Starting ProtocolHandler [ajp-nio-8009] 25-Oct-2016 11:41:03.771 INFO [main] org.apache.catalina.startup.Catalina.start Server startup in 36712 ms

像這樣

因為我使用的是tomcat 8，所以我的代碼是這樣的 

package accounter

import grails.boot.GrailsApp
import grails.boot.config.GrailsAutoConfiguration
import javax.naming.NamingException;
import javax.sql.DataSource;
import org.springframework.context.annotation.Bean;
import org.springframework.jndi.JndiObjectFactoryBean;

class Application extends GrailsAutoConfiguration {
    static void main(String[] args) {
        GrailsApp.run(Application, args)
    }


    @Bean(destroyMethod="")
    public DataSource jndiDataSource() throws IllegalArgumentException, NamingException {
        JndiObjectFactoryBean bean = new JndiObjectFactoryBean();
        bean.setJndiName("java:comp/env/jdbc/akyDS");
        bean.setProxyInterface(DataSource.class);
        bean.setLookupOnStartup(false);
        bean.afterPropertiesSet();
        return (DataSource)bean.getObject();
    }
}

然后在context.xml 

<?xml version="1.0" encoding="UTF-8"?>

<!-- The contents of this file will be loaded for each web application -->
<Context>

    <!-- Default set of monitored resources. If one of these changes, the    -->
    <!-- web application will be reloaded.                                   -->
    <WatchedResource>WEB-INF/web.xml</WatchedResource>
    <WatchedResource>${catalina.base}/conf/web.xml</WatchedResource>

    <Resource name="jdbc/akyDS"
                auth="Container"
                type="javax.sql.DataSource"
                maxIdle="25"
                minIdle="5"
                initialSize="5"
                validationQuery="SELECT 1"
                timeBetweenEvictionRunsMillis="60000"
                minEvictableIdleTimeMillis="60000"
                username="root"
                password="root"
                driverClassName="com.mysql.jdbc.Driver"
                url="jdbc:mysql://localhost:3306/accounter?autoReconnect=true"
    />

    <!-- Uncomment this to disable session persistence across Tomcat restarts -->
    <!--
    <Manager pathname="" />
    -->
</Context>

但是當我嘗試運行我的tomcat時，我得到了這樣的日志。

卡塔利娜原木

但是當我訪問localhost:8090/時，我看不到我的項目成功啟動

將級別日志設置為DEBUG時出現此錯誤

在刪除application.yml此代碼后，我得到一些錯誤

與刪除此代碼，然后我運行grails prod war之后，我嘗試再次部署。

我收到此錯誤。

頂部的三個日志語句與此無關，它們是INFO語句，而不是錯誤。

您顯示的其他輸出同樣不是錯誤，它告訴您（連同一堆配置設置）它已完成一些MySQL連接，並將它們返回到連接池，這正是您在使用時希望看到的內容連接池。 它以jdbc:mysql://localhost:3306/accounter?autoReconnect=true形式顯示數據庫的URL，這是從context.xml中配置的數據源中顯示的內容。

基本上省略了所有的連接細節 

Releasing JDBC Connection ... after transaction
Returning JDBC Connection to DataSource

這里沒有任何內容表明為什么您可能無法從瀏覽器訪問應用程序，但是就數據庫連接而言，一切看起來都不錯。
