使用JNDI Connection进行Grails 3.1.1部署

Question

我正在使用grails 3.1.1，我试图用jndi连接来配置我的应用程序，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

像这样

因为我使用的是tomcat 8，所以我的代码是这样的

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>

但是当我尝试运行我的tomcat时，我得到了这样的日志。

卡塔利娜原木

但是当我访问localhost:8090/时，我看不到我的项目成功启动

将级别日志设置为DEBUG时出现此错误

在删除application.yml此代码后，我得到一些错误

与删除此代码，然后我运行grails prod war之后，我尝试再次部署。

我收到此错误。

顶部的三个日志语句与此无关，它们是INFO语句，而不是错误。

您显示的其他输出同样不是错误，它告诉您（连同一堆配置设置）它已完成一些MySQL连接，并将它们返回到连接池，这正是您在使用时希望看到的内容连接池。 它以jdbc:mysql://localhost:3306/accounter?autoReconnect=true形式显示数据库的URL，这是从context.xml中配置的数据源中显示的内容。

基本上省略了所有的连接细节

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

这里没有任何内容表明为什么您可能无法从浏览器访问应用程序，但是就数据库连接而言，一切看起来都不错。
