我有一个包含 2 个子项目(后端和 ui)的 gradle 项目。 Ui由gradle tomcatRunWar完美启动.后端有我们在生产地点的配置描述符<tomcat home>/conf/Catalina/localhost/portal-api.xml它包含一些资源定义，如数据库数据源(剪切部分):
<?xml version='1.0' encoding='UTF-8'?>
<Context>
<!-- Database access -->
<!-- For information about these DataSource Pool properties see: http://www.tomcatexpert.com/blog/2010/04/01/configuring-jdbc-pool-high-concurrency -->
<Resource type="javax.sql.DataSource" name="jdbc/EgaisDataSource" description="Database for EGAIS portal" factory="org.apache.tomcat.jdbc.pool.DataSourceFactory" driverClassName="org.postgresql.Driver" url="jdbc:postgresql://egais.perf.db.master:5432/e....>
<Resource name="mail/EgaisMail" auth="Container" type="javax.mail.Session" mail.transport.protocol="smtp" mail.smtp.host="smtp.mail.ru" mail.smtp.port="465" mail.smtp.starttls.enable="true" mail.smtp.socketFactory.port="465" mail.smtp.socketFactory.cla....>
<Environment name="ru.rlh.egais.portal.url" value="http://lesegais.ru/portal" type="java.lang.String"/>
</Context>
上下文本身 <tomcat home>/conf/context.xml很简单:
<?xml version='1.0' encoding='utf-8'?>
<Context>
<WatchedResource>WEB-INF/web.xml</WatchedResource>
</Context>
我的后端 gradle 构建看起来像(略有截断):
apply plugin: 'war'
apply plugin: 'com.bmuschko.tomcat'
buildscript {
repositories {
mavenCentral()
jcenter()
}
dependencies {
classpath 'com.bmuschko:gradle-tomcat-plugin:2.2.2'
}
}
dependencies {
def tomcatVersion = '7.0.57'
tomcat "org.apache.tomcat.embed:tomcat-embed-core:${tomcatVersion}",
"org.apache.tomcat.embed:tomcat-embed-logging-juli:${tomcatVersion}",
"org.apache.tomcat.embed:tomcat-embed-jasper:${tomcatVersion}",
'org.slf4j:jul-to-slf4j:1.7.12',
'org.slf4j:slf4j-simple:1.7.12',
'ch.qos.logback:logback-classic:1.1.3',
'ch.qos.logback:logback-core:1.1.3',
'javax.mail:mail:1.5.0-b01',
'org.apache.xmlbeans:xmlbeans:2.6.0',
'com.mchange:c3p0:0.9.5.1',
'org.apache.tomcat:tomcat-jdbc:8.0.24',
'org.postgresql:postgresql:9.4-1201-jdbc41'
...
}
tomcat{
contextPath = 'portal-api'
httpPort = 8081
}
[tomcatRun, tomcatRunWar]*.configFile = file('/opt/configuration/context-backend.xml')
最后一行是我尝试通过官方常见问题解答的方式。
看来我离胜利很近了——tomcat 启动了，但随后立即停止了:

附言最初我在插件的作者那里问过:https://github.com/bmuschko/gradle-tomcat-plugin/issues/130但是一时半会儿没有任何答案...
最佳答案
https://github.com/bmuschko/gradle-tomcat-plugin/issues/129#issuecomment-145356377 花了很多时间...我将 gradle 从 2.2 升级到 2.7 以及项目中的一些库。我不能确切地说出更多的变化，但它现在可以通过文档向前推进。 我认为这只是旧的 gradle 问题。
同时回答该问题以标记它不再需要关注。
关于tomcat - Gradle tomcat 插件尝试启动 tomcat 两次，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/31963314/
