我有 2 个子项目（后端和 ui）的 gradle 项目。Ui 完美地从gradle tomcatRunWar. 后端有配置描述符，我们在生产位置<tomcat home>/conf/Catalina/localhost/portal-api.xml它包含一些资源定义，如数据库数据源（可爱的部分）：
<?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 gradle 后端构建看起来像（略微截断）：
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')
最后一行是我如何尝试通过官方常见问题处理它。
看来我接近胜利了——tomcat 启动，但随后立即停止：
